extracranial/intracranial bypass

bypass

[bi´pas″] an auxiliary flow; a shunt; a surgically created pathway circumventing the normal anatomical pathway, such as in an artery or the intestine.

Bypass. Single artery bypass of an occluded right coronary artery. From Dorland's, 2000.aortocoronary bypass coronary artery bypass.aortofemoral bypass insertion of a vascular prosthesis from the aorta to the femoral artery to bypass atherosclerotic occlusions in the aorta and the iliac artery.aortoiliac bypass insertion of a vascular prosthesis from the abdominal aorta to the femoral artery to bypass intervening atherosclerotic segments.axillofemoral bypass insertion of a vascular prosthesis or section of saphenous vein from the axillary artery to the ipsilateral femoral artery to relieve lower limb ischemia in patients in whom normal anatomic placement of a graft is contraindicated, as by abdominal infection or aortic aneurysm.axillopopliteal bypass insertion of a vascular prosthesis from the axillary artery to the popliteal artery to relieve lower limb ischemia in patients in whom the femoral artery is unsuitable for axillofemoral bypass.cardiopulmonary bypass diversion of the flow of blood from the entrance to the right atrium directly to the aorta, usually via a oxygenator" >pump oxygenator, avoiding both the heart and the lungs; a form of extracorporeal circulation used in heart surgery.coronary bypass (coronary artery bypass) a section of saphenous vein or other conduit grafted between the aorta and a coronary artery distal to an obstructive lesion in the latter; called also aortocoronary bypass.extra-anatomic bypass an arterial bypass that does not follow the normal anatomic pathway, such as an axillofemoral bypass.extracranial/intracranial bypass anastomosis of the superficial temporal artery to the middle cerebral artery to preserve function or prevent stroke or death in patients with stenosis of the internal carotid or middle cerebral artery.femorofemoral bypass insertion of a vascular prosthesis between the femoral arteries to bypass an occluded or injured iliac artery.femoropopliteal bypass insertion of a vascular prosthesis from the femoral to the popliteal artery to bypass occluded segments.gastric bypass see gastric bypass.hepatorenal bypass insertion of a vascular prosthesis between the common hepatic artery and the renal artery, serving as a passage around an occluded segment of renal artery.intestinal bypass (jejunoileal bypass) see intestinal bypass.left heart bypass diversion of the flow of blood from the pulmonary veins directly to the aorta, avoiding the left atrium and the left ventricle.partial bypass the deviation of only a portion of the blood flowing through an artery.partial ileal bypass anastomosis of the proximal end of the transected ileum to the cecum, the bypass of the portion of the small intestine resulting in decreased intestinal absorption of and increased fecal excretion of cholesterol; sometimes used in treatment of hyperlipidemia.right heart bypass diversion of the flow of blood from the entrance of the right atrium directly to the pulmonary arteries, avoiding the right atrium and right ventricles.
