A second bypass may be required if a blockage forms in the bypass graft later on. Over time, there is a decreasing trend of percentage patency (likelihood a vessel will remain open) in popliteal bypass surgery, 88% in the first year, 79% and 76% at 3 and 5 years respectively. [13]
On the other hand, lithoplasty balloon angioplasty may represent a safe tool to treat CFA stenosis. [7] The superficial femoral artery [8] is a designation for the segment between the branching point of the deep femoral artery and the adductor hiatus, passing through the subsartorial canal.
The great saphenous vein is the conduit of choice for vascular surgeons, [5] when available, for performing peripheral arterial bypass operations. The saphenous vein may undergo vein graft failure after engraftment, but still it has superior long-term patency compared to synthetic grafts ( PTFE , PETE (Dacron)), human umbilical vein grafts or ...
Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used for venous access in cases of trauma, and hypovolemic shock when the use of a peripheral venous catheter is either difficult or impossible.
The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle.It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries.
The Blalock–Thomas–Taussig shunt (BTT shunt), [1] previously known as the Blalock–Taussig Shunt (BT shunt), [2] is a surgical procedure used to increase blood flow to the lungs in some forms of congenital heart disease [3] such as pulmonary atresia and tetralogy of Fallot, which are common causes of blue baby syndrome.

Emergency bypass surgery for the treatment of an acute myocardial infarction (MI) is less common than PCI or thrombolysis. From 1995 to 2004, the percentage of people with cardiogenic shock treated with primary PCI rose from 27.4% to 54.4%, while the increase in coronary artery bypass graft surgery (CABG) was only from 2.1% to 3.2%.

Atherectomy is a minimally invasive technique for removing atherosclerosis from blood vessels within the body. It is an alternative to angioplasty for the treatment of peripheral artery disease, but the studies that exist are not adequate to determine whether it is superior to angioplasty. [1]
