CHIVA method is a type of surgery used to treat varicose veins that occur as a result of long term venous insufficiency. [1] The term is a French acronym for Conservatrice Hémodynamique de l'Insuffisance Veineuse en Ambulatoire (ambulatory conservative hemodynamic treatment venous insufficiency).
A medical illustration of lower extremity varicose veins. Lower extremity varicose veins is the condition in which the superficial veins become tortuous (snakelike) and dilated (enlarged) to greater than 3 mm (0.12 in) in the upright position. [24]
Varicose veins are unlikely to be caused by crossing the legs or ankles. [17] Less commonly, but not exceptionally, varicose veins can be due to other causes, such as post-phlebitic obstruction or incontinence, venous and arteriovenous malformations. [18] Venous reflux is a significant cause. Research has also shown the importance of pelvic ...
Radiofrequency ablation is a minimally invasive procedure used in the treatment of varicose veins. It is an alternative to the traditional stripping operation. Under ultrasound guidance, a radiofrequency catheter is inserted into the abnormal vein and the vessel treated with radio-energy, resulting in closure of the involved vein.
The great saphenous vein is exposed and the common femoral and subsartorial veins are identified before dividing. The vein is ligated close to the junction with of the femoral vein. [ 3 ] If the ligation is distal from the saphenofemoral junction , it will leave out small tributaries which may later cause recurrence of varicosities.
To create the bypass graft, a surgeon will remove or "harvest" healthy blood vessels from another part of the body, either arteries from an arm or the chest, or veins from a leg. [1] This vessel becomes a graft , with one end attaching to a blood source above and the other end below the blocked area, creating a "conduit" channel or new blood ...
