Dysplazja włóknisto-mięśniowa
Objawy

Dysplazja włóknisto-mięśniowa (FMD) to rzadkie schorzenie naczyniowe charakteryzujące się nieprawidłowym rozwojem komórek ścian tętnic, prowadzącym do ich zwężenia (stenozy), tętniaków oraz rozwarstwień. Najczęściej zajmuje tętnice nerkowe i szyjne wewnętrzne, dotykając głównie kobiety w wieku 30-50 lat (średni wiek debutu około 47 lat). Objawy zależą od lokalizacji zmian i obejmują nadciśnienie tętnicze (często oporne), zaburzenia czynności nerek, bóle głowy, szumy uszne, zawroty głowy, a także poważne powikłania naczyniowe jak udar mózgu, zawał serca czy krwawienie podpajęczynówkowe. U około 40% pacjentów obserwuje się poważne zdarzenia naczyniowe, a czynniki ryzyka progresji to m.in. płeć męska, palenie tytoniu oraz zajęcie wielu łożysk naczyniowych. Rozwarstwienia tętnic występują u około 20% chorych, najczęściej w tętnicach szyjnych zewnątrzczaszkowych (72,7% przypadków). FMD może prowadzić do przewlekłej niewydolności nerek, atrofii nerki, a także do powikłań neurologicznych i sercowo-naczyniowych.

Dysplazja włóknisto-mięśniowa – charakterystyka

Dysplazja włóknisto-mięśniowa (FMD – Fibromuscular Dysplasia) jest rzadkim schorzeniem naczyniowym charakteryzującym się nieprawidłowym rozwojem lub wzrostem komórek w ścianach tętnic. Prowadzi to do pogrubienia tkanki mięśniowej i włóknistej, powodując zwężenie tętnic (stenozę), co ogranicza przepływ krwi do narządów i może prowadzić do ich uszkodzenia. Choroba ta może również powodować powstawanie tętniaków (uwypukleń ściany tętnicy) oraz rozwarstwienia (rozdarcia ściany tętnicy).123

FMD najczęściej dotyczy tętnic średniej i dużej wielkości, szczególnie tętnic nerkowych i szyjnych wewnętrznych, choć może wystąpić w niemal każdym łożysku naczyniowym. Zmiany mogą również obejmować tętnice kręgowe, trzewne i biodrowe zewnętrzne.45

Choroba ta dotyka przede wszystkim kobiety (ponad 90% przypadków), zwłaszcza w wieku od 30 do 50 lat, przy czym średni wiek w momencie pojawienia się pierwszych objawów to około 47 lat. Mężczyźni również mogą chorować na FMD, i choć występuje u nich rzadziej, często przebieg choroby jest cięższy, z większym ryzykiem powikłań takich jak tętniaki czy rozwarstwienia tętnic.6789

Objawy kliniczne dysplazji włóknisto-mięśniowej

Objawy dysplazji włóknisto-mięśniowej są bezpośrednio związane z lokalizacją zajętych tętnic, stopniem ich zwężenia oraz wystąpieniem ewentualnych powikłań naczyniowych. Wielu pacjentów z FMD nie doświadcza żadnych objawów i choroba zostaje wykryta przypadkowo podczas badań obrazowych wykonywanych z innych przyczyn.101112

Objawy związane z zajęciem tętnic nerkowych

Zajęcie tętnic nerkowych jest najczęstszą manifestacją FMD, a typowymi objawami są:

  • Nadciśnienie tętnicze (najczęstszy objaw, często oporne na leczenie)513
  • Zaburzenia czynności nerek wykrywane w badaniach laboratoryjnych1415
  • Ból w okolicy lędźwiowej (spowodowany rozwarstwieniem lub zawałem nerki)516
  • Zmniejszenie rozmiaru nerki (atrofia)1417
  • Szmer naczyniowy słyszalny w badaniu osłuchowym nad jamą brzuszną lub w okolicy lędźwiowej185
  • Hipokaliemia w wyniku wtórnego hiperaldosteronizmu518
  • Przewlekła niewydolność nerek (rzadko)1117

Objawy związane z zajęciem tętnic szyjnych i kręgowych

Zajęcie tętnic szyjnych i kręgowych może prowadzić do następujących objawów:195

  • Ból głowy (często migreny)2021
  • Szum pulsacyjny w uszach (tinnitus pulsacyjny) – opisywany jako „szum” lub „świst” zsynchronizowany z rytmem serca2016
  • Zawroty głowy lub uczucie wirowania (vertigo)2223
  • Ból szyi13
  • Udar mózgu lub przemijający atak niedokrwienny (TIA)2425
  • Zespół Hornera (opadnięcie powieki, nierówność źrenic) w przypadkach rozwarstwienia2226
  • Zaburzenia widzenia (niewyraźne widzenie lub przejściowa utrata wzroku)1917
  • Osłabienie lub drętwienie twarzy1918
  • Szmer naczyniowy słyszalny nad tętnicą szyjną2016

Objawy związane z zajęciem tętnic trzewnych (krezkowych)

Zajęcie tętnic krezkowych, zaopatrujących jelita, wątrobę i śledzionę, występuje rzadziej, ale może powodować:2728

  • Ból brzucha po posiłku (ból poposiłkowy)2229
  • Niezamierzoną utratę masy ciała1416
  • Objawy niedokrwienia jelit (rzadko)3031

Objawy związane z zajęciem tętnic kończyn

W przypadku zajęcia tętnic kończyn górnych i dolnych mogą wystąpić:3233

Objawy związane z zajęciem tętnic wieńcowych

FMD może również dotyczyć tętnic wieńcowych, powodując:3536

  • Ból w klatce piersiowej3237
  • Duszność3738
  • Zawał serca (rzadko)3532
  • Spontaniczne rozwarstwienie tętnicy wieńcowej (SCAD), szczególnie u kobiet, które niedawno urodziły2739

Progresja i przebieg choroby

Przebieg dysplazji włóknisto-mięśniowej jest zróżnicowany i może zależeć od wielu czynników, w tym lokalizacji zmian naczyniowych, ich nasilenia oraz współistniejących czynników ryzyka.4041

Naturalna historia choroby

U większości pacjentów FMD ma stabilny przebieg, a progresja choroby jest rzadka lub powolna:4243

  • Wiele osób z FMD nie doświadcza żadnych objawów przez całe życie i choroba zostaje wykryta przypadkowo4342
  • U bezobjawowych pacjentów z przypadkowo wykrytą FMD rokowanie jest stosunkowo dobre4425
  • Choroba zwykle nie wpływa na długość życia – wielu pacjentów z FMD dożywa 80-90 lat1445

Jednak w niektórych przypadkach FMD może postępować i prowadzić do poważnych powikłań:4637

  • U mniejszości pacjentów, szczególnie u dzieci i młodych dorosłych, może dochodzić do szybkiej progresji zmian z dramatycznymi powikłaniami4647
  • Obustronna FMD tętnic nerkowych lub ogniskowa FMD (pojedyncze lub kilka izolowanych zwężeń) wydają się bardziej podatne na progresję4647
  • U około 40% pacjentów z FMD występują poważne zdarzenia naczyniowe, takie jak rozwarstwienie tętnicy, udar, zawał serca lub krwawienie podpajęczynówkowe4841

Palenie tytoniu wydaje się być istotnym czynnikiem zwiększającym ryzyko progresji i ciężkości FMD. U osób palących z FMD odnotowano wyższy odsetek tętniaków (24,8% vs 18,9% u osób niepalących) oraz tendencję do częstszego występowania poważnych zdarzeń naczyniowych.4649

Czynniki wpływające na przebieg choroby

Na przebieg kliniczny FMD wpływają następujące czynniki:5051

  • Lokalizacja zmian naczyniowych – zajęcie tętnic mózgowych lub wieńcowych wiąże się z gorszym rokowaniem4041
  • Płeć – mężczyźni z FMD częściej doświadczają rozwarstwień tętnic i tętniaków w porównaniu do kobiet506
  • Obecność tętniaków lub rozwarstwień tętnic zwiększa ryzyko poważnych powikłań4850
  • Współistniejące czynniki ryzyka sercowo-naczyniowego, szczególnie palenie tytoniu4946

Powikłania dysplazji włóknisto-mięśniowej

FMD może prowadzić do szeregu poważnych powikłań, które w znaczącym stopniu wpływają na rokowanie i jakość życia pacjentów.5237

Powikłania naczyniowe

Najczęstsze powikłania naczyniowe FMD to:5053

  • Rozwarstwienie tętnic (arterial dissection) – występuje u około 20% pacjentów z FMD, najczęściej w tętnicach szyjnych zewnątrzczaszkowych (72,7% przypadków)4854
    • Rozwarstwienie tętnic szyjnych i kręgowych może prowadzić do udaru mózgu lub TIA4425
    • Spontaniczne rozwarstwienie tętnicy wieńcowej (SCAD) może prowadzić do zawału serca3955
  • Tętniaki – osłabienie ściany tętnic w przebiegu FMD może prowadzić do powstawania tętniaków3755
    • Najczęściej występują w tętnicach szyjnych zewnątrzczaszkowych, tętnicach nerkowych i tętnicach wewnątrzczaszkowych5348
    • Pęknięcie tętniaka może prowadzić do krwawienia podpajęczynówkowego lub wewnątrzczaszkowego, co stanowi zagrożenie życia2256

Powikłania narządowe

FMD może prowadzić do uszkodzenia narządów docelowych na skutek przewlekłego niedokrwienia:5751

  • Powikłania nerkowe:
    • Nadciśnienie oporne na leczenie558
    • Postępujące upośledzenie czynności nerek5440
    • Atrofia nerki1617
    • Zawał nerki1548
    • Niewydolność nerek (rzadko u dorosłych, częściej u dzieci)5958
  • Powikłania mózgowo-naczyniowe:
    • Udar mózgu lub TIA2160
    • Krwawienie podpajęczynówkowe5848
    • Trwałe uszkodzenie neurologiczne5659
  • Powikłania sercowo-naczyniowe:
    • Choroba wieńcowa5552
    • Zawał serca3532
    • Niewydolność serca5552
  • Powikłania jelitowe:

Czynniki ryzyka powikłań

Czynniki zwiększające ryzyko wystąpienia powikłań FMD obejmują:4950

  • Płeć męska – mężczyźni z FMD mają wyższe ryzyko rozwarstwień i tętniaków506
  • Palenie tytoniu – zwiększa ryzyko wystąpienia tętniaków i poważnych zdarzeń naczyniowych4946
  • Zajęcie wielu łożysk naczyniowych jednocześnie5940
  • Obecność FMD w tętnicach mózgowych4041
  • Ogniskowa postać FMD (w przeciwieństwie do wieloogniskowej)4647

Wpływ dysplazji włóknisto-mięśniowej na jakość życia

FMD może znacząco wpływać na jakość życia pacjentów, przede wszystkim poprzez:4263

  • Przewlekłe objawy takie jak bóle głowy, szumy uszne i zawroty głowy, które mogą być uciążliwe w codziennym funkcjonowaniu4264
  • Konieczność regularnego monitorowania ciśnienia tętniczego i stosowania leków przeciwnadciśnieniowych6365
  • Potrzebę regularnych kontroli lekarskich i badań obrazowych6328
  • Ograniczenia aktywności fizycznej, szczególnie u pacjentów z wysokim ryzykiem rozwarstwienia tętnic6366
  • Lęk związany z ryzykiem wystąpienia poważnych powikłań67

Różnica między momentem wystąpienia pierwszych objawów a postawieniem diagnozy jest znacząca – według danych z rejestru amerykańskiego średni czas od pojawienia się objawów do diagnozy wynosi 3,6 ± 7,4 lat, a w badaniu z Paryża stwierdzono dziewięcioletnie opóźnienie między wystąpieniem nadciśnienia a diagnozą u pacjentów z wieloogniskową FMD tętnic nerkowych.848

Podsumowanie kliniczne

Dysplazja włóknisto-mięśniowa to złożone schorzenie naczyniowe o zróżnicowanej manifestacji klinicznej, zależnej przede wszystkim od lokalizacji zajętych tętnic. Choroba może przebiegać bezobjawowo lub powodować szereg objawów, od nadciśnienia tętniczego po udary mózgu i zawały serca.49

Choroba u większości pacjentów ma stabilny, powolny przebieg i nie wpływa istotnie na długość życia. Jednak w niektórych przypadkach, szczególnie u mężczyzn, palaczy tytoniu oraz pacjentów z zajęciem wielu łożysk naczyniowych, może prowadzić do poważnych powikłań takich jak rozwarstwienia tętnic i tętniaki.424650

Chociaż nie ma lekarstwa na FMD, odpowiednie leczenie i monitorowanie mogą skutecznie kontrolować objawy i zapobiegać powikłaniom. Kluczowe znaczenie ma wczesna diagnoza i kompleksowa opieka przez zespół specjalistów z doświadczeniem w leczeniu tej rzadkiej choroby naczyniowej.13943

    https://www.mayoclinic.org/diseases-conditions/fibromuscular-dysplasia/symptoms-causes/syc-20352144
    In fibromuscular dysplasia, the muscle and fiber tissues in the arteries thicken, causing the arteries to narrow. This is called stenosis. Narrowed arteries can reduce blood flow to the organs, causing organ damage. The artery to the kidney is called the renal artery. Fibromuscular dysplasia of the renal artery is shown here, with a „string of beads” appearance. […] Symptoms of fibromuscular dysplasia depend on which artery or arteries are affected. Some people don’t have any symptoms. […] If the arteries to the kidneys are affected, common symptoms include: High blood pressure. Problems with how the kidneys work. […] If the arteries affected supply blood to the brain, symptoms might include: Headache. A pulsing feeling or ringing sound in your ears, called tinnitus. Dizziness. Sudden neck pain. Stroke or transient ischemic attack. […] Treatments are available to control symptoms and help prevent complications, such as stroke. But there is no cure for fibromuscular dysplasia.

    https://www.tgh.org/institutes-and-services/conditions/fibromuscular-disease
    Fibromuscular dysplasia (FMD) is a rare blood vessel disorder characterized by abnormal fibrous cell growth in the walls of medium- and large-sized arteries, causing them to stiffen and weaken. This can lead to arterial narrowing (stenosis), reducing blood flow to vital organs and increasing the risk of serious complications, such as aneurysms. […] In some cases, fibromuscular disease does not cause symptoms and is detected through an imaging test performed for an unrelated reason. When noticeable symptoms occur, they can vary depending on the severity of the condition and which arteries are affected, such as: […] Symptoms can include headaches (migraine or nonmigraine), dizziness, ringing or whooshing sounds in the ears (pulsatile tinnitus), neck pain and vision problems. Additionally, if blood flow to the brain is disrupted, a transient ischemic attack (TIA) or stroke may occur.

    https://www.uptodate.com/contents/clinical-manifestations-and-diagnosis-of-fibromuscular-dysplasia
    Fibromuscular dysplasia (FMD) is a noninflammatory, nonatherosclerotic disorder that leads to arterial stenosis, occlusion, aneurysm, dissection, and arterial tortuosity. These findings have been observed in nearly every arterial bed. The most frequently involved arteries are the renal and internal carotid arteries, followed by the vertebral, visceral, and external iliac arteries. Disease presentation may vary widely, depending upon the arterial segment involved and the severity of disease. […] The epidemiology, pathogenesis, clinical manifestations, and diagnosis of FMD in adults are reviewed here. The treatment of FMD and the general evaluation for possible renovascular hypertension and stroke are discussed separately.
  • #5 Fibromuscular Dysplasia – StatPearls – NCBI Bookshelf

    Fibromuscular dysplasia (FMD) is a rare systemic vascular disease, affecting younger women and accounting for 10% to 20% of the cases of renal artery stenosis. FMD classically presents as renovascular hypertension but can also manifest as stroke in young adults. Early diagnosis and treatment are important for a long-term prognosis. […] FMD classically presents as renovascular hypertension but can also manifest as stroke in young adults. […] Hypertension, specifically resistant hypertension, is the most common presentation of renal FMD. Other features of renal FMD include renal artery dissection, flank pain, hematuria, renal infarct, hypokalemia from secondary hyperaldosteronism, and abdominal bruit. […] Diagnosis of renal artery FMD should prompt screening for associated carotid artery lesions to prevent catastrophic complications. Cranio-cervical FMD may be asymptomatic and found incidentally on imaging studies. Clinical manifestations include headache, pulsatile tinnitus, dizziness, cervical artery dissection, neck pain, stroke, Horner syndrome, subarachnoid hemorrhage, and carotid bruit.

    https://my.clevelandclinic.org/departments/heart/depts/fibromuscular-dysplasia-clinic
    Fibromuscular dysplasia (FMD) is an uncommon vascular disease. Patients with FMD have abnormal cellular growth in the walls of their medium and large arteries. This can cause the arteries with the abnormal growth to look beaded. The arteries may also become narrow (stenosis) and in some cases may develop aneurysms (bulging) or dissections (artery tears). […] The majority (more than 90%) of patients with FMD are women. However, men can also have FMD, and those who do have a higher risk of complications such as aneurysms (bulging) or dissections (tears) in the arteries. […] Most patients follow-up in 6 months to 1 year or as needed. In some cases, patients may be referred for additional vascular procedures, such as angioplasty or vascular surgery or treatment of an aneurysm.
  • #7 Fibromuscular dysplasia – Wikipedia
    https://en.wikipedia.org/wiki/Fibromuscular_dysplasia
    Symptoms expressed by FMD patients are largely dependent on the vascular bed(s) affected by the disease. […] In a study from the United States Registry for Fibromuscular Dysplasia, the median age at first symptom was roughly 47 years. […] The main symptoms associated with renal FMD are secondary hypertension and bruits that can be heard with a stethoscope over the abdomen or flanks. […] Complications such as aneurysms, dissections, or occlusion of the renal artery have been associated with renal artery FMD. […] Patients with FMD in the carotid arteries typically present around 50 years of age.

    https://www.fmdsa.org/fmd-info/
    Fibromuscular Dysplasia, commonly called FMD, is a disease that causes one or more arteries in the body to have abnormal cell development in the artery wall. As a result, areas of narrowing (called stenosis), aneurysms, or tears (called dissections) may occur. If narrowing or a tear causes a decrease in blood flow through the artery, symptoms may result. Many people with FMD do not have any symptoms or signs on physical examination and are diagnosed by accident during a radiology scan for another problem. […] The signs and/or symptoms that a person with FMD may experience depend on the arteries affected and whether there is evidence narrowing, tears, or aneurysms within those affected arteries. Any pain or clinical sign related to FMD typically comes from the organ that is supplied by that artery. For example, FMD in the renal arteries may cause high blood pressure. FMD in the carotid arteries may cause headaches or a swooshing sound in the ears (called pulsatile tinnitus). Some patients with FMD may have no symptoms at all but are diagnosed with this disease when a physician hears a noise over one of the arteries due to disturbed or turbulent blood flow within the vessel. This noise is known as a bruit.
  • #17 FAQs about Fibromuscular Dysplasia
    https://www.massgeneral.org/vascular-center/treatments-and-services/faq-fibromuscular-dysplasia
    Fibromuscular dysplasia (FMD) is the abnormal development or growth of cells in the walls of the bodys arteries. As a result of this growth, areas of the arteries can thicken, narrow and even enlarge, making it difficult for blood to flow through them.

    The observed natural history of FMD in asymptomatic incidentally diagnosed cases is relatively benign. However, in some cases the initial diagnosis of FMD is made in the setting of stroke, which as a manifestation of FMD, is most often because of concomitant cervical artery dissection (CeAD). Compared with the general population, FMD is associated with a higher prevalence of intracranial aneurysms, particularly in women. […] The most common neurologic manifestation of FMD is migraine. Nearly 80% of individuals with cerebrocervical FMD report headaches, most commonly migraine. […] Cervical artery dissection (CeAD) presents with stroke or TIA in approximately 70% of cases, and typically occurs in the first few weeks postdissection. […] The incidence of stroke or TIA is often latent to arterial injury because the intramural hematoma expands and risk of intraluminal thromboembolism rises. As the vessel heals over weeks to months the risk of stroke decreases with an estimated long-term risk of recurrence ranging in incidence from 1% to 3%. […] The incidence of stroke in FMD is primarily associated with CeAD and can be managed conservatively with antiplatelet therapy and avoidance of high-risk cervical exertion.

[…] Some patients experience no symptoms of the disease while others may have high blood pressure, dizziness or vertigo, chronic headache, intracranial aneurysm, ringing in the ears, weakness or numbness in the face, neck pain, or changes in vision. […] Currently there is no cure for FMD. Medicines and angioplasty can reduce the risk of initial or recurrent stroke. In rare cases, FMD-related aneurysms can burst and bleed into the brain, causing stroke, permanent nerve damage, or death.

    Fibromuscular disease often affects the renal arteries, which can cause kidney dysfunction and secondary high blood pressure. […] If FMD affects major arteries that supply vital organs, reduced blood flow can damage those organs. […] Even after treatment, fibromuscular disease may progress, and its symptoms may recur. […] If fibromuscular dysplasia affects the carotid or vertebral arteries, it may reduce blood flow to the brain, increasing the risk of a TIA or stroke.

    Fibromuscular dysplasia (FMD), formerly called fibromuscular fibroplasia, is a group of nonatherosclerotic, noninflammatory arterial diseases that most commonly involve the renal and carotid arteries. The prevalence of symptomatic renal artery FMD is about 4/1000 and the prevalence of cervicocranial FMD is probably half that. Renovascular hypertension is the most common manifestation of renal artery FMD. Multifocal stenoses with the 'string-of-beads’ appearance are observed at angiography in more than 80% of cases, mostly in women aged between 30 and 50 years; they generally involve the middle and distal two-thirds of the main renal artery and in some case also renal artery branches. Cervicocranial FMD can be complicated by dissection with headache, Horner’s syndrome or stroke, or can be associated with intracerebral aneurysms with a risk of subarachnoid or intracerebral hemorrhage. Stenosis progression in renal artery FMD is slow and rarely leads to ischemic renal failure.

    FMD affecting the arteries of the head and neck is commonly recognized as a cause of childhood strokes. […] Symptoms may include headaches, insomnia, fatigue, and chest or abdominal pain. […] Kidney failure is a common presentation in infants and children but is uncommon in adults, although it is occasionally the presenting problem in adults with focal disease. […] In some cases, if not managed properly, FMD-related aneurysms can occur and cause bleeding into the brain, resulting in a stroke, permanent nerve damage, or death. […] Those who present with FMD in multiple vascular beds, or focal disease involving multiple branches of the renal arteries, may develop renal artery dissection or progressive renal impairment, therefore having a more difficult and complex prognostic course.

    Pulsatile tinnitus, or the sensation of hearing a rhythmic pulsing sound in the ears, affects around 30-40% of FMD patients. […] Dizziness is reported by about 20-30% of FMD patients, particularly those with involvement of the carotid or vertebral arteries. […] Transient ischemic attacks (TIAs), also known as mini-strokes, occur in approximately 10-15% of FMD patients. […] Renal artery stenosis, or narrowing of the arteries that supply blood to the kidneys, is present in up to 75% of FMD patients. […] Stroke is a serious but less common complication of FMD, occurring in about 5-10% of patients. […] Vision changes, such as blurred vision, double vision, or temporary loss of vision, occur in about 10-20% of FMD patients. […] Chest pain occurs in approximately 10-15% of FMD patients, particularly those with involvement of the coronary arteries, which supply blood to the heart.

    Long-standing involvement of the renal arteries may lead to a history of hypertension. Rarely, abdominal pains, and even a history of ischemic bowel, may indicate mesenteric or visceral artery involvement. Vascular compromise of the limbs by FMD lesions may cause ischemic symptoms such as intermittent leg claudication. […] The complications of fibromuscular dysplasia (FMD) can be diverse, notably because it is a systemic vascular disease. […] Any symptoms compatible with ischemia and angiographic findings should prompt consideration of FMD as the underlying etiology. Symptoms include neurologic deficits, angina pectoris, limb claudication, and abdominal pain.

    Fibromuscular dysplasia is frequently asymptomatic. Symptomatic patients commonly present with: […] hypertension, or less commonly renal impairment, due to renal artery stenosis […] CNS symptoms (e.g. headache, neck pain, pulsatile tinnitus, Horner syndrome) from transient ischemic attack, stroke, or dissection due to carotid and vertebral artery involvement […] angina, myocardial infarction or sudden cardiac death due to coronary artery involvement […] symptoms of mesenteric ischemia (mesenteric infarction is rare due to the formation of collateral supply). […] Asymptomatic cases are only observed but if symptomatic then fibromuscular dysplasia responds well to angioplasty, with high long-term patency rates.

    Fibromuscular Dysplasia, or FMD, is a rare condition that affects the blood vessels. […] When it does, the symptoms can manifest as high blood pressure, pain or organ issues. […] For Madison DeCamp, Donor Services Coordinator, symptoms started shortly after her 21st birthday. When she began to experience blood pressure spikes and abdominal pain, her doctor ordered an ultrasound. […] The scan revealed my renal arteries had been compromised, Madison said. My kidneys were only functioning at 40% due to my arteries twisting and beading which cut off the blood supply. […] Madisons day-to-day life shifted as she began monitoring her blood pressure twice a day, taking blood pressure medication, and going in for renal ultrasounds and CT scans of her brain and heart every six months to monitor her condition. […] I have to avoid strenuous activity because my heart can tear easily, Madison said.

    Fibromuscular dysplasia (FMD) is a rare vascular condition characterized by abnormal thickening of certain artery walls. This thickening can lead to narrowing (stenosis), aneurysms, or dissections, which may reduce blood flow to vital organs. […] The progression of FMD varies widely. Some individuals remain asymptomatic for years, while others may develop significant symptoms depending on which arteries are affected. […] Headaches are a common symptom of fibromuscular dysplasia (FMD), affecting 60-70% of patients. […] Hypertension, or high blood pressure, is one of the most common clinical manifestations of FMD, affecting up to 80% of patients. […] Abdominal pain occurs in about 20-30% of FMD patients, particularly those with involvement of the mesenteric arteries, which supply blood to the intestines.

    The patients pain was initially mild and achy, but pain increased with physical activities such as jogging. […] He also experienced worsening weakness and fatigue in his left lower extremity toward the end of his runs. […] Signs and symptoms in the carotid or vertebral arteries may include dizziness, pulsatile tinnitus, headache, transient ischemic attack, intracerebral hemorrhage, carotid and vertebral arterial dissection, Horners syndrome, or stroke. […] Many of the signs and symptoms of FMD are non-specific, which is 1 reason there can be a 4 to 9-year delay in diagnosis. […] The clinical features vary by which artery is being affected; hypertension is the most common feature when the renal artery is involved. […] The presence of symptoms during exercise suggests possible exercise-induced ischemia.

    Fibromuscular dysplasia (FMD) is a rare condition that causes narrowing (stenosis) and/or enlargement (aneurysm) of the small and medium-sized arteries. […] Some people with fibromuscular dysplasia dont have any symptoms. […] For those that do, the most common symptoms are associated with high blood pressure. However, many people with high blood pressure do not have symptoms in the early stages, and are picked up at a routine health check. When high blood pressure does cause symptoms this can include headaches, breathlessness, blurred vision and dizziness. […] Rarely FMD can cause strokes or chest pain, pain after eating and weight loss, pain weakness or numbness in the neck or limbs. […] Other symptoms can vary depending on which parts of the body are affected. […] FMD can cause a number of complications if left untreated. This includes high blood pressure and tears in the walls of your arteries if you already have FMD present e.g. carotid (neck) arteries. This is called arterial dissection and the symptoms are similar to having a mini stroke or stroke.
