  Although there’s no cure for KTS, your doctor can help you manage symptoms and prevent complications. […] Because KTS may affect many systems in the body, your health care team may include specialists in vascular medicine and surgery, skin diseases (dermatology), interventional radiology, orthopedic surgery, physical therapy and rehabilitation, and other areas as needed. […] You and your doctor can work together to determine which of the following treatments are most appropriate for you. Treatments may include: […] Compression therapy. Bandages or elastic garments are wrapped around affected limbs to help prevent swelling, problems with varicose veins and skin ulcers. These bandages or elastic garments often need to be custom-fit. Intermittent pneumatic compression devices leg or arm sleeves that automatically inflate and deflate at set intervals may be used.

  Klippel-Trnaunay syndrome (KTS) is a rare congenital vascular malformation syndrome defined as capillary and venous malformations, and hypertrophy of the limb with or without lymphatic malformation. Currently there is no cure for KTS but the majority of patients are advised to wear compression garments on the affected limb to control swelling and discomfort. […] Compression therapy was used specially to control lymphoedema and venous insufficiency. […] Compression therapy is essential in the treatment of Klippel-Trnaunay syndrome (KTS). […] Individualised compression therapy is beneficial for alleviating the swelling and lymphoedema associated with KTS. […] None of the treatment methods sufficiently reduced the patients limb oedema, but our case still highlights the importance of continuous individualised compression therapy in the treatment of lymphoedema combined with congenital vascular malformations.

  https://my.clevelandclinic.org/health/diseases/17152-klippel-trenaunay-syndrome-kts

  Although Klippel-Trenaunay syndrome doesnt have a cure, many treatments can help you manage symptoms. Early diagnosis and treatment (often soon after birth) can reduce the risk of health complications related to KTS. […] Klippel-Trenaunay syndrome treatment varies based on symptoms. Treatment may include: […] Blood-thinning medicines. Anticoagulants like heparin reduce the risk of blood clots in your legs and pulmonary embolism. […] Sirolimus. Providers typically use this drug to prevent transplanted organ rejection. But it can stop vascular malformation from getting worse. […] Compression stockings. These special socks help blood return to your heart. They can decrease leg swelling and pain and reduce clot risks. […] Endovenous thermal ablation. This treatment uses focused beams of energy inside blood vessels to close off problem veins. The veins stay in place so you can heal faster, with less pain.

  Laser or radiofrequency ablation of veins. This minimally invasive procedure is used to close off malformed veins. […] MR-guided ablation. Blood vessels are treated with a laser or cautery under MRI guidance. […] Sclerotherapy. A solution is injected into a vein, which creates scar tissue that helps close the vein. […] Surgery. In some cases, surgical removal or reconstruction of affected veins, removal of excess tissue, and correction of the overgrowth of bone may be beneficial. […] Medication. Some people have benefited from oral medications that may help to treat complex vascular and lymphatic malformations that cause symptoms. But these drugs may have significant side effects that require monitoring. Topical sirolimus may help relieve symptoms of superficial vascular malformations. Studies are ongoing to determine the effectiveness and safety of these medications in people with KTS. […] In addition, treatment may be needed for complications such as bleeding, infection, blood clots or skin ulcers. Special care may be needed during pregnancy to prevent complications.

  https://emedicine.medscape.com/article/1084257-treatment

  Surgical intervention in the treatment of varicosities and venous malformations is controversial. One might consider surgery for either significant cosmetic deformity or the symptoms of pain, heaviness of the leg, bleeding, or infectious complications. Venous stripping, ligation, excision, or sclerotherapy are contraindicated unless the surgery involves the superficial system and the underlying deep system is normal or demonstrates only mild-to-moderate reflux. Lymphaticovenular anastomosis may represent a desirable approach. […] Endovenous laser therapy of the greater saphenous vein is gaining support for the management of varicosities in the general public and in patients with KTWS. This therapy has been used alone and in combination with other surgical interventions. It is a novel and minimally invasive approach for the management of some varicosities. […] Endovenous mechanochemical ablation for varicoses veins in pediatric KTWS patients appears safe and effective.

  Regarding limb hypertrophy, heel inserts are generally sufficient for limb discrepancies of 1.5 cm or less. For greater discrepancies, orthopedic surgery may be considered. Possible orthopedic procedures include osteotomy, epiphysiodesis, or epiphyseal stapling. Rarely, amputation is required due to recurrent infections, nonhealing ulcers, or recurrent bleeding. […] In Klippel-Trenaunay-Weber syndrome (KTWS), laser treatment of the hemangioma can be effective in lightening the color of the port-wine stain. Currently, the flashlamp-pumped pulsed dye laser is the treatment of choice in vascular lesions. Laser treatment is also indicated in the case of ulceration. Ulceration of hemangiomas can be painful and can impair functional abilities. When treated with laser, ulcers often heal more quickly. Laser treatment is most effective when performed early, as it can improve the long-term appearance of the port-wine stain and thereby also improve function. Typically, many treatments are required to achieve the desired effect. Laser treatment only helps with the superficial component of the hemangioma.

  Some children need debulking surgery to remove abnormal vessels and overgrown tissue. This procedure can help reduce the size of your child’s affected limb and improve function. […] KTS can cause your child’s foot or leg to become excessively large. Orthopedic procedures include those that reshape the foot to better fit into a shoe, as well as epiphysiodesis, a procedure that stops the leg from growing once a child reaches his or her early teens. […] An interventional radiologist is a board-certified specialist who performs minimally invasive, targeted treatments throughout the body that do not require open surgery. For KTS, these include: […] The Vascular Anomalies Center (VAC) at Boston Children’s specializes in innovative, family-centered care for children with KTS. From your first visit, you’ll work with a team of professionals who are committed to supporting all your family’s physical and psychosocial needs. KTS is a progressive condition, which means that it will grow as your child grows. That said, many kids — especially those with mild cases of KTS — go on to live normal, healthy lives. Treatment for your child’s symptoms is the most effective way to manage the disease. […] Surgeons at Boston Children’s are leading the charge in removing the extra tissue that grows as a result of KTS. In what’s called a debulking procedure, our surgeons remove a great deal of the extra tissue, which can allow your child to regain leg function.

  At present, there is no cure for the disease; rather, symptomatic treatment is employed in order to improve the patients’ quality of life. […] A conservative approach should be employed towards the symptomatic treatment of KTS by the use of non-invasive measures. In the majority of the cases of KTS, the patient is advised to wear elastic or non-elastic compression stockings. […] Pain is a common feature of KTS, affecting as many as 88% of those affected. Therefore, patients with KTS require pain management frequently. […] Surgery is usually reserved for symptomatic cases.

  https://emedicine.medscape.com/article/1084257-treatment

  Treatment for Klippel-Trenaunay-Weber syndrome (KTWS) is conservative and symptomatic. Compression garments are indicated for chronic venous insufficiency, lymphedema, recurrent cellulitis, and recurrent bleeding from capillary or venous malformations of the extremity. The compression garment may also protect the limb from trauma. Intermittent pneumatic compression pumps may also provide benefit. However, in some patients with absent or hypoplastic deep venous systems, elastic compression may increase venous stasis and cause discomfort. Pain management can be a very important aspect of caring for patients with KTWS. Referral to a pain clinic and/or a multidisciplinary team including a pain management specialist is recommended. […] Cellulitis and thrombophlebitis can be managed with analgesics, elevation, antibiotics, and corticosteroids. In patients with a history of recurrent cellulitis, intermittent or prophylactic antibiotics may be considered. Anticoagulant therapy is indicated in acute thrombosis and prophylactically prior to surgical procedures. Given the risk of thrombotic events, women with KTWS should avoid using oral contraceptive pills. There remains a question as to which patients would benefit from prophylactic treatment with director oral anticoagulants to prevent serious thromboembolic events and/or reduce pain.

  Klippel-Trnaunay syndrome is typically a complex combined capillary-lymphatic-venous malformation in lower limb. […] Gastrointestinal involvement is common in KTS patients, which can be a source of significant morbidity and even mortality. […] Conservative management has been successfully used in many patients to manage iron deficiency anemia from bleeding. Invasive treatments included surgical resection of involved bowel, and interventional approaches, and increasingly reported sclerotherapy. […] There are no current recommendations for managing of gastrointestinal VM in KTS. […] For example, a popular treatment, sclerotherapy can be preferred for anorectal VM managing, but primary sclerotherapy is not suitable for anorectosigmoid VM in KTS, since norectosigmoid VM has distinct pathophysiologies from anorectal VM.

  Despite advances in gene discovery, treatment remains mainly procedural via surgery and other invasive procedures. Relief from these treatments is most often temporary. […] The multi-site trial at UWMadison is in its first phase and is testing a personalized topical medication in the form of a gel as a way to treat vascular anomalies. […] The topical gel, called VT30 Topical Gel, allows Drolet and other trial researchers to deliver the drug directly to the affected tissue through the patients skin, which also limits exposure of the medication to healthy tissue. […] The phase 1/2 study has enrolled patients who have venous, lymphatic, and venolymphatic malformations, which are tumor-like lesions combined both venous and lymphatic vessel structures. The study is evaluating the safety of the drug and how well patients tolerate its use.

  Surgery has largely been replaced by more minimally invasive techniques, including embolization using coils, vascular plugs and other materials, endovenous laser ablation therapy (EVLT) such as radiofrequency ablation (RFA), and sclerotherapy. These methods occlude abnormal veins and avoid the potential surgical complications of poor wound closure and persistent bleeding, and are first-line therapies for persistent KTS. […] EVLT can be used to treat persistent embryonic veins, and acts by emitting a wavelength of light that generates photon-induced damage to the vessel wall as well as thermal damage to the surrounding area. […] Sclerotherapy can treat a variety of vascular diseases, including the persistent embryonic veins in KTS. In sclerotherapy, catheter injection of a sclerosant, either alone or in combination with other minimally invasive techniques, damages the intimal wall of the vessel and induces thrombosis. […] Treatment for this syndrome has historically been surgical, which can be associated with significant complications. New minimally invasive techniques, including RFA, EVLT, and sclerotherapy, have expanded treatment options with fewer complications.

  KTS is a complex condition, and a full cure is often not achievable. However, some different treatment options are available to help in the reduction of limb overgrowth and cosmetic appearance. Management is usually conservative and symptomatic, and surgical intervention is rare. […] Compression therapy is the main treatment for children presenting with KTS. It assists in minimising swelling in the affected limbs, in turn reducing tissue overgrowth. […] The main purpose of this treatment is to enable your child to participate in activities as much as possible, as this is important for their development. Compression therapy involves applying pressure onto the affected limb which is done by applying bandages or wearing a compression garment. A pressure garment is worn 24 hours a day, and may be required lifelong, or only when your child goes through significant growth periods, deepening on the symptoms. […] Compression garments are custom-made to make it as easy as possible for you to apply. Children may also find the garment uncomfortable initially. However, many children often soon realise that the compression assists in reducing pain and discomfort, and become accustomed to the garment.

  https://journals.cambridgemedia.com.au/jwm/volume-24-number-3/compression-therapy-patient-klippel-trenaunay-syndrome

  Klippel-Trnaunay syndrome (KTS) is a rare congenital vascular malformation syndrome defined as capillary and venous malformations, and hypertrophy of the limb with or without lymphatic malformation. Currently there is no cure for KTS but the majority of patients are advised to wear compression garments on the affected limb to control swelling and discomfort. […] Compression therapy was used specially to control lymphoedema and venous insufficiency. […] Compression therapy is essential in the treatment of Klippel-Trnaunay syndrome (KTS). […] Individualised compression therapy is beneficial for alleviating the swelling and lymphoedema associated with KTS. […] None of the treatment methods sufficiently reduced the patients limb oedema, but our case still highlights the importance of continuous individualised compression therapy in the treatment of lymphoedema combined with congenital vascular malformations.

  Currently, there is no cure for KTS, and the goal of treatment is to reduce symptoms. Treatment may require a multi-disciplinary team approach: […] Skincare: It is vital to prevent infections of the skin and bleeding from scratching. A person may also receive antibiotics and pain medication to help manage infections. […] Orthotics: A doctor may monitor any discrepancies in limb length and suggest orthotics or surgical corrections as necessary. […] Compression stockings: These stockings apply pressure to the legs to help maintain blood flow and prevent swelling. […] Sclerotherapy: This treatment for varicose veins involves injecting a solution into blood or lymph vessels that causes them to shrink. […] Laser treatment: Options such as a pulse dye laser (PDL) may help treat the appearance of port-wine stains. A 2019 study on infants with port-wine stains notes that 41.1% of people had a 7699% improvement in port-wine stain appearance, while 25.9% had 100% clearance of their port-wine stains.

  Surgical intervention in the treatment of varicosities and venous malformations is controversial. One might consider surgery for either significant cosmetic deformity or the symptoms of pain, heaviness of the leg, bleeding, or infectious complications. Venous stripping, ligation, excision, or sclerotherapy are contraindicated unless the surgery involves the superficial system and the underlying deep system is normal or demonstrates only mild-to-moderate reflux. Lymphaticovenular anastomosis may represent a desirable approach. […] Endovenous laser therapy of the greater saphenous vein is gaining support for the management of varicosities in the general public and in patients with KTWS. This therapy has been used alone and in combination with other surgical interventions. It is a novel and minimally invasive approach for the management of some varicosities.

  Surgery has largely been replaced by more minimally invasive techniques, including embolization using coils, vascular plugs and other materials, endovenous laser ablation therapy (EVLT) such as radiofrequency ablation (RFA), and sclerotherapy. These methods occlude abnormal veins and avoid the potential surgical complications of poor wound closure and persistent bleeding, and are first-line therapies for persistent KTS. […] EVLT can be used to treat persistent embryonic veins, and acts by emitting a wavelength of light that generates photon-induced damage to the vessel wall as well as thermal damage to the surrounding area. […] Sclerotherapy can treat a variety of vascular diseases, including the persistent embryonic veins in KTS. In sclerotherapy, catheter injection of a sclerosant, either alone or in combination with other minimally invasive techniques, damages the intimal wall of the vessel and induces thrombosis. […] Treatment for this syndrome has historically been surgical, which can be associated with significant complications. New minimally invasive techniques, including RFA, EVLT, and sclerotherapy, have expanded treatment options with fewer complications.

  Segmental excision of the lateral marginal vein (LMV) was performed in 8 patients over the past 2 years with an effective reduction in edema. The reduction in edema is because there is venous stasis that occurs secondary to the presence of avalvulosis and resultant lack of venous valves leading to venous hypertension and progressive chronic venous insufficiency. […] Endovenous ablation (EVA) and coil embolization were not offered as these are associated with higher risk of VTE, coil embolization due the avalvulosis and lack of media/smooth muscle in the LMV. […] Patients who presented with bleeding had a D-dimer and platelet count done, and if D-dimer was elevated they were started on low molecular weight heparin (LMWH), and compression bandaging and the D-dimer repeated on day 3 with a platelet count. Once the bleeding stopped, LMWH was discontinued 2 weeks later, with the intention of healing of the wound while on multilayer bandages.

  Laser therapy can be used to treat or manage the port-wine stains, although to a limited extent. It is also used to treat small varicose veins and as an adjuvant for sclerotherapy or endovascular ablation. […] Problematic varicose veins can be closed off by using high-frequency radio waves to create local heat in the affected vein. This is generally associated with fewer risks and faster recovery compared to ligation and stripping. […] If the asymmetry between the affected and unaffected legs is predicted to be greater than 2 cm, epiphysiodesis can be performed to slow the growth in the longer leg. This procedure involves prematurely fusing the growth plate of a bone and needs to be timed correctly to match the lengths of the legs by the end of the growth phase. Alternatively, the normal leg can also be lengthened surgically to achieve matching size.
