In the legs, bypass grafting is used to treat peripheral vascular disease, acute limb ischemia, aneurysms and trauma.While there are many anatomical arrangements for vascular bypass grafts in the lower extremities depending on the location of the disease, the principle is the same: to restore blood flow to an area without normal flow.
With surgery operations such as popliteal bypass, there will be an increased probability of blood clot formation. In rare cases, a part of the clot in the leg breaks free and travels to the lungs, this is also known as a pulmonary embolism. A blockage in the blood vessels of the lung can be formed by pulmonary embolism, and this could cause ...
Aneurysms can also be classified by their location: Ultrasonography of an aneurysm of the great saphenous vein due to venous valve insufficiency. Arterial and venous, with arterial being more common. [8] The heart, including coronary artery aneurysms, ventricular aneurysms, aneurysm of sinus of Valsalva, and aneurysms following cardiac surgery.
The bypass versus angioplasty in severe ischemia of the leg (BASIL) trial investigated infrainguinal bypass surgery first compared to angioplasty first in select patients with severe lower limb ischemia who were candidates for either procedure. The BASIL trial found that angioplasty was associated with less short term morbidity compared with ...

A popliteal artery aneurysm (PAA) is a bulging of the popliteal artery. [1] A PAA is diagnosed when a focal dilation greater than 50% of the normal vessel diameter is found (the normal diameter of a popliteal artery is 0.7-1.1 cm). PAAs are the most common aneurysm of the peripheral vascular system, accounting
If the femoral artery has to be ligated surgically to treat a popliteal aneurysm, blood can still reach the popliteal artery distal to the ligation via the genicular anastomosis. However, if flow in the femoral artery of a normal leg is suddenly disrupted, blood flow distally is rarely sufficient.
Endovascular aneurysm repair (EVAR) is a type of minimally-invasive endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair."
