  The most common conditions associated with thrombophilia are deep vein thrombosis (DVT) and pulmonary embolism (PE), collectively known as venous thromboembolism (VTE). DVT typically occurs in the legs and is characterised by pain, swelling, and redness. The clot may migrate to the lungs, causing PE, which can lead to sudden shortness of breath, chest pain, palpitations, and potentially catastrophic outcomes like collapse and cardiac arrest. […] Thrombosis can also occur in unusual sites such as the veins of the brain, liver, mesentery, kidneys, and arms. Thrombophilia has been linked to recurrent miscarriage and pregnancy complications like intrauterine growth restriction, stillbirth, severe pre-eclampsia, and abruptio placentae. […] Thrombosis results from a combination of factors such as abnormalities in blood vessel walls, blood flow, and blood consistency. Thrombophilia specifically involves abnormalities in blood consistency due to imbalances in coagulation factors. The coagulation process involves a cascade of activations leading to the formation of a fibrin clot, which is regulated by various inhibitors. In thrombophilia, this balance is disturbed, increasing the likelihood of clot formation.

  Thrombophilias are a common group of disorders that make a person more likely to develop blood clots in the veins of their legs, pelvis or lungs. […] Symptoms of deep vein thrombosis include pain, swelling, redness or warmth in the affected area. […] Symptoms of pulmonary embolism include shortness of breath, chest pain that worsens with a deep breath, fast heart beat, sweating, fainting and coughing with blood in the sputum. […] Pregnant women with thrombophilia have a greater chance of having certain pregnancy complications possibly linked to blood clots in the placentas. […] At the present time, the standard of care for pregnant women with thrombophilia is close monitoring for the development of these pregnancy complications. If these complications occur, they are treated accordingly. However, no treatment has been proven to prevent these complications in pregnant women with thrombophilia.

  https://gesund.bund.de/en/thrombophilia

  The symptoms of a pulmonary embolism are sudden breathlessness, chest pain, rapid heartbeat, a drop in blood pressure, coughing up blood and fainting (syncope). […] Often, people with thrombophilia are unaware that they develop more blood clots than normal, as many blood clots simply dissolve naturally on their own. However, sometimes the blood clots disrupt blood flow and cause symptoms. […] If a blood clot occurs, for example, in the leg veins that run at a deep level between the muscle layers, this impairs the flow of blood from the affected leg towards the heart. As a result, more fluid is retained in the tissues, leading to swelling and pains or feelings of tightness in the affected muscles. […] Fresh blood clots may break free and be washed away in the bloodstream. They pass through the right side of the heart and into the lungs, where they block blood vessels, leading to a pulmonary embolism. A severe pulmonary embolism may have a fatal outcome.

  https://patient.info/allergies-blood-immune/blood-clotting-tests/thrombophilia

  There are no symptoms unless the thrombophilia results in a blood clot (thrombosis). […] Many people with thrombophilia do not develop a blood clot and have no symptoms at all. […] A blood clot in a vein is the most common problem with thrombophilia – this is called venous thrombosis. Possible symptoms are: Pain and swelling in a leg. This occurs if you have a blood clot in a large vein in a leg. This is commonly known as a deep vein thrombosis (DVT). A DVT can occur in any vein in your body but most often affects a leg vein. […] The blood clot may travel to the heart and on into a lung, causing a pulmonary embolism. Possible symptoms are chest pain, pain on deep breathing, shortness of breath or, rarely, collapse. […] Some types of thrombophilia can cause a blood clot in an unusual site such as the brain, gut or liver. This can cause symptoms in the head or the tummy (abdomen). A blood clot in the liver veins is called Budd-Chiari syndrome.

  The presence of HAD can be established with a blood test. […] Blood clots with antithrombin deficiency occur at an average age of 30 and can appear in unusual locations, such as the veins of the brain or gastrointestinal tract, or in multiple veins simultaneously. […] Approximately 50 percent of people with HAD will experience a blood clot in their lifetime and 40 percent will experience a pulmonary embolism specifically. […] Antiphospholipid syndrome (APS) is a condition that poses particular risks for pregnant women because APS-related blood clots occur most frequently in advance of or in the weeks following childbirth. […] It can lead to miscarriage. […] Unlike most thrombophilias, APS is associated with a higher incidence of recurrent venous blood clots as well as arterial blood clots.

• #21 Thrombophilia: Causes, Symptoms, and Treatment

  https://patient.info/allergies-blood-immune/blood-clotting-tests/thrombophilia

  A blood clot in an artery can occur with some types of thrombophilia. This is called arterial thrombosis. Depending on which artery is affected, a blood clot in an artery can cause a stroke, a heart attack or problems with the placenta during pregnancy. So the possible symptoms of arterial thrombosis due to thrombophilia are: Having a stroke at a relatively young age. […] Repeated miscarriages. […] Pregnancy problems: pre-eclampsia, reduced fetal growth or, rarely, fetal death (a stillbirth, or intrauterine death). […] A heart attack. […] It is important to remember that all of these conditions can be due to causes other than thrombophilia.

• #22 Blood Clots With Hemophilia: What Is Thrombophilia? | MyHemophiliaTeam

  https://www.myhemophiliateam.com/resources/blood-clots-with-hemophilia-what-is-thrombophilia

  Pulmonary embolism occurs when a blood clot breaks loose from its original site (like a leg affected by DVT) and enters the lungs, blocking blood flow. This potentially life-threatening condition is a medical emergency that requires immediate treatment. […] Arterial thrombosis happens when a blood clot forms in an artery, which carries blood from your heart to the rest of your body. This type of clot can block blood flow to vital organs, leading to serious consequences. […] At first glance, hemophilia and thrombophilia seem to be opposite conditions. However, people with hemophilia can sometimes also be at risk for blood clots. Multiple factors can cause people with hemophilia to develop thrombophilia. […] Some hemophilia treatments involve infusing clotting factors to prevent bleeding. Using high doses of factor replacement therapy for instance, to treat people with severe hemophilia can raise the risk of clot formation.

• #23 What Is Thrombophilia? – Klarity Health Library

  https://my.klarity.health/what-is-thrombophilia/

  Another presentation of thrombophilia is a pulmonary embolism. This is when a clot occurs in a vein in the lungs, causing symptoms including shortness of breath and pain during inspiration. […] Thrombophilia can also cause strokes known as ischaemic strokes. Ischaemic stroke occurs when a clot forms in one of the arteries of the brain, blocking off circulation and causing tissue to lose blood flow, causing a phenomenon known as ischaemia. Ischaemia can lead to tissue death in the brain, and therefore cause lifelong brain damage. Symptoms of stroke to watch out for include slurring of speech, weakness of the limbs or face (particularly on one side of the body) and visual changes or vision loss. […] Lastly, clots that form sporadically can lead to heart attacks. They occur when the clot moves to the arteries that supply oxygen to the muscle walls of the heart, known as the coronary arteries. Signs of heart attacks include chest pain that may also be felt in the arms and the shoulder/neck/back, shortness of breath, nausea and vomiting. Considering these symptoms of thrombophilia, it is unsurprising that patients with a diagnosis often have long-term disabilities or chronic health conditions due to repeated clots.

• #24 Thrombophilia – Wikipedia

  https://en.wikipedia.org/wiki/Thrombophilia

  Thrombophilia has been linked to recurrent miscarriage, and possibly various complications of pregnancy such as intrauterine growth restriction, stillbirth, severe pre-eclampsia and abruptio placentae. […] Protein C deficiency may cause purpura fulminans, a severe clotting disorder in the newborn that leads to both tissue death and bleeding into the skin and other organs. The condition has also been described in adults. Protein C and protein S deficiency have also been associated with an increased risk of skin necrosis on commencing anticoagulant treatment with warfarin or related drugs. […] Whether thrombophilia also increases the risk of arterial thrombosis (which is the underlying cause of heart attacks and strokes) is less well established. However, more recent data suggest some forms of inherited thrombophilia are associated with increased risk for arterial ischemic stroke.

• #25 Maternal inherited thrombophilia and pregnancy outcomes

  https://pmc.ncbi.nlm.nih.gov/articles/PMC7401936/

  Thrombophilia is a group of genetical disorders that cause blood to clot abnormally. Thrombophilia is linked to recurrent pregnancy loss, foetal growth restriction, late miscarriages, stillbirth and preeclampsia. […] Thrombophilia contributes to more than half of thromboembolic events during pregnancy. […] Thrombophilic defects can be accompanied by the following manifestations: Repeated miscarriages, intrauterine growth restriction, preeclampsia, HELLP syndrome and neonatal fulminant purple. […] Multiple studies have reported an association between thrombophilia defects and adverse pregnancy outcomes, including both preeclampsia and intrauterine growth restriction. […] The most common maternal indication for early termination of pregnancy is preeclampsia, the most common fetal indication for early termination of pregnancy is intrauterine growth restriction accompanied by acute fetal distress.

• #26 Factor V Leiden thrombophilia: MedlinePlus GeneticsLock

  https://medlineplus.gov/genetics/condition/factor-v-leiden-thrombophilia/

  Factor V Leiden thrombophilia is an inherited disorder of blood clotting. Factor V Leiden is the name of a specific gene mutation that results in thrombophilia, which is an increased tendency to form abnormal blood clots that can block blood vessels. […] People with factor V Leiden thrombophilia have a higher than average risk of developing a type of blood clot called a deep venous thrombosis (DVT). DVTs occur most often in the legs, although they can also occur in other parts of the body, including the brain, eyes, liver, and kidneys. Factor V Leiden thrombophilia also increases the risk that clots will break away from their original site and travel through the bloodstream. These clots can lodge in the lungs, where they are known as pulmonary emboli. […] The factor V Leiden mutation is associated with a slightly increased risk of pregnancy loss (miscarriage). Women with this mutation are two to three times more likely to have multiple (recurrent) miscarriages or a pregnancy loss during the second or third trimester.

  About 30 percent of all people who experience a blood clot have no known risk factors, and in about half of these cases of unprovoked clots, thrombophilia is identified. […] Although thrombophilia increases one’s risk for a blood clot, it by no means guarantees one. […] The lifetime risk of developing DVT is 10 percent or less for certain thrombophilias, but the degree of risk fluctuates based on a number of considerations. […] Heterozygous conditions may increase your blood clot risk several-fold. […] On the other hand, homozygous conditions may multiply your risk by as much as 25 to 50 times the norm.

• #35 Prothrombin thrombophilia: MedlinePlus GeneticsLock

  https://medlineplus.gov/genetics/condition/prothrombin-thrombophilia/

  Prothrombin thrombophilia is a disorder that increases the risk of developing blood clots. Thrombophilia is the term used to describe an increased tendency to form blood clots. After an injury, clots protect the body by sealing off damaged blood vessels and preventing further blood loss. People with thrombophilia can develop clots when they are not needed. These clots can block normal blood flow and cause harm. […] People who have prothrombin thrombophilia have a higher-than-average risk of developing a type of clot called a deep vein thrombosis, which typically occurs in the blood vessels of the arms or legs. People with prothrombin thrombophilia also have an increased risk of developing a pulmonary embolism, which is a clot that travels through the bloodstream and lodges in the lungs. […] While many people with prothrombin thrombophilia will never have clotting issues, several factors increase a person’s risk of blood clots. Some risk factors that contribute to the development of harmful blood clots include surgery, injury or trauma, air travel, obesity, and a family history of blood clots. Additional risk factors include pregnancy, using contraceptives such as birth control pills or patches that contain estrogen, and receiving post-menopausal hormone replacement therapy. The combination of prothrombin thrombophilia and other clotting disorders may also increase a person’s risk.

• #37 Factor V Leiden thrombophilia: MedlinePlus GeneticsLock

  https://medlineplus.gov/genetics/condition/factor-v-leiden-thrombophilia/

  The chance of developing an abnormal blood clot depends on whether a person has one or two copies of the factor V Leiden mutation in each cell. People who inherit two copies of the mutation, one from each parent, have a higher risk of developing a clot than people who inherit one copy of the mutation. […] The presence of one copy of the factor V Leiden mutation increases that risk to 3 to 8 in 1,000, and having two copies of the mutation may raise the risk to as high as 80 in 1,000.

• #38 The Genetics of Thrombophilia – Blood Clots

  https://www.stoptheclot.org/about-clots/thrombophilia/genetics-of-thrombophilia/

  People who have a mutation in the prothrombin gene produce more prothrombin protein than is normal. Since there is more of the prothrombin protein in the blood, this increases the tendency for clotting. […] If a person is homozygous (that is, he or she inherits a mutation in both copies of their gene, one from each parent) they are at a greater risk to develop a blood clot than an individual who is heterozygous. […] An individual can also have a greater risk to develop a blood clot if they inherit a mutation in more than one of the genes that lead to thrombophilia.

  The risk of developing thrombosis varies. For instance, the cumulative risk by age 60 is about 12% in those without thrombophilia, but much higher in those with deficiencies in natural anticoagulants. Factor V Leiden and prothrombin mutation carriers have a slightly higher risk, often dependent on additional factors like immobilisation.

  It is important to understand that some thrombosis symptoms may resemble those of other more common medical problems. Because some of these symptoms can also point to other conditions, it’s important to have your child evaluated by a qualified medical professional for an accurate diagnosis and prompt treatment. If you have a family history of thrombosis, it is important to bring this up during evaluation for these symptoms. […] Some deep vein thromboses may resolve without treatment. Treatment is given to help get rid of the blood clot and to minimize complications of thrombosis. If the blood clot remains, other veins will enlarge to bypass the blockage. Sometimes these veins are visible, like varicose veins. After a blood clot some people develop long-term pain and swelling in the leg called post-thrombotic syndrome, which is caused by reduced blood flow and damage to the affected vein. […] Blood clots in the thigh are more likely to break off and travel to the lungs than blood clots below the knee or in the arms. A pulmonary embolism can be a life-threatening emergency, requiring immediate medical attention.

  Thrombophilia has been linked to recurrent miscarriage, and possibly various complications of pregnancy such as intrauterine growth restriction, stillbirth, severe pre-eclampsia and abruptio placentae. […] Protein C deficiency may cause purpura fulminans, a severe clotting disorder in the newborn that leads to both tissue death and bleeding into the skin and other organs. The condition has also been described in adults. Protein C and protein S deficiency have also been associated with an increased risk of skin necrosis on commencing anticoagulant treatment with warfarin or related drugs. […] Whether thrombophilia also increases the risk of arterial thrombosis (which is the underlying cause of heart attacks and strokes) is less well established. However, more recent data suggest some forms of inherited thrombophilia are associated with increased risk for arterial ischemic stroke.

• #44 Hereditary Thrombophilia | Contact

  https://contact.org.uk/conditions/hereditary-thrombophilia/

  In the most common form of inherited thrombophilia, factor V Leiden, the leg may become swollen, painful and red. In some individuals, part of the clot may be dislodged and flow to the lung (pulmonary embolism) which may make breathing difficult. Depending on the size of the blood clot, some individuals may experience severe respiratory difficulty whereas in others breathing problems may be barely noticeable. In very rare cases, a clot might occur in the arm, brain, or liver. Since clots associated with factor V Leiden form in the veins (which take blood to the heart), there is no increased risk of coronary occlusion. However, pregnancy loss and other obstetric complications may occur at an increased rate in women with factor V Leiden. It is important to look for the presence of factor V Leiden in women who experience recurrent miscarriages as it can be treated to reduce the risk of these events occurring.

  Thrombophilia is defined as a predisposition (susceptibility) to thrombosis. […] Most persons with a thrombophilia do not develop thrombosis. […] Hyperhomocysteinemia is a weak risk factor for incident and recurrent VTE. […] In one study, VTE patients with plasma homocysteine above the 90th percentile (20.1 mol/L) had a 1.8-fold increased risk for VTE recurrence. […] Finally, in one study, Hashimotos thyroiditis and pernicious anemia were associated with 5.3- and 3.9-fold increased risk for VTE.

  Increasing evidence suggests that psychosocial factors, including depression predict incident venous thromboembolism (VTE) against a background of genetic and acquired risk factors. […] We hypothesized that depressive symptoms in patients with prior VTE are associated with an increased risk of recurrent VTE. […] Clinically relevant depressive symptoms (HADS-D score 8) were present in 10% of patients. […] After controlling for sociodemographic and clinical factors, a 3-point increase on the HADS-D score was associated with a 44% greater risk of recurrent VTE (OR 1.44, 95% CI 1.02, 2.06). […] Compared to patients with lower levels of depressive symptoms (HADS-D score: range 0-2), those with higher levels (HADS-D score: range 3-16) had a 4.1-times greater risk of recurrent VTE (OR 4.07, 95% CI 1.55, 10.66). […] The findings suggest that depressive symptoms might contribute to an increased risk of recurrent VTE independent of other prognostic factors.

• #50 Blood Clotting Disorders: Types, Signs and Treatment

  https://my.clevelandclinic.org/health/diseases/16788-blood-clotting-disorders-hypercoagulable-states

  A blood clotting disorder makes your blood form clots too easily. This is also called a hypercoagulable state or thrombophilia. […] Blood clotting disorder symptoms can vary depending on where in your body you have a blood clot. Symptoms may include: Swelling, tenderness and pain in your leg can mean you have a deep vein thrombosis. Chest pain with shortness of breath can mean a possible pulmonary embolism. Heart attack. Stroke. […] Hypercoagulable states are usually genetic (inherited from parents) or acquired conditions. The genetic form of this disorder means you’re born with the tendency to form blood clots. Acquired conditions are usually a result of surgery, trauma, medications or a medical condition that increases the risk of forming clots. […] If you inherited your blood clotting disorder from your parents, you’ll have it for the rest of your life. Although that doesn’t mean you’ll get a blood clot, there may be times in your life when an additional risk factor increases the risk you already have. Many acquired coagulation disorders go away when the situation that caused them goes away. For example, when you’re up and moving again after a long plane ride, your risk of clots goes back down.

• #52 Factor V Leiden – Wikipedia

  https://en.wikipedia.org/wiki/Factor_V_Leiden

  The symptoms of factor V Leiden vary among individuals. There are some individuals who have the F5 gene and who never develop thrombosis, while others have recurring thrombosis before the age of 30 years. This variability is influenced by the number of F5 gene (chromosome 1) mutations a person has, the presence of other gene alterations related to blood clotting, and circumstantial risk factors, such as surgery, use of oral contraceptives and pregnancy. […] Symptoms of factor V Leiden include: Having a first DVT (deep vein thrombosis) or PE (pulmonary embolism) before age 50. Having recurring DVT or PE. Having venous thrombosis in unusual sites in the body such as the brain or the liver. Having a DVT or PE during or right after pregnancy. Having a history of unexplained pregnancy loss in the second or third trimester. Having a DVT or PE and a strong family history of venous thromboembolism.

  Most people with thrombophilia don’t have symptoms. Symptoms only occur if thrombophilia causes a blood clot. […] If you have thrombophilia, you’re more likely to develop a blood clot in one of the large veins in your leg (deep vein thrombosis) or a pulmonary embolism, where the blood clot breaks off, travels in the circulation and lodges in the arteries supplying the lungs. […] The symptoms of a pulmonary embolism are: chest or upper back pain, shortness of breath, coughing usually dry, but you may cough up blood or mucus containing blood, lightheadedness or dizziness, fainting. […] If you have thrombophilia, you need to be aware of the symptoms of a blood clot and see your GP immediately if you think you have one.
