| splenorenal ligament | <anatomy> A peritoneal fold (portion of the greater omentum) which extends from the diaphragm and the anterior aspect of the left kidney to the hilar region of the spleen, conducting the splenic vessels from the posterior body wall to the spleen. Synonym: ligamentum lienorenale, ligamentum phrenicolienale, ligamentum splenorenale, lienophrenic ligament, lienorenal ligament, ligamentum phrenicosplenicum, phrenicolienal ligament, phrenicosplenic ligament, phrenosplenic ligament, sustentaculum lienis. (05 Mar 2000) |
| splenorenal shunt | Anastomosis of the splenic vein to the left renal vein, usually end-to-side, for control of portal hypertension. Synonym: renal-splenic venous shunt. (05 Mar 2000) |
| splenorenal shunt, surgical | Anastomosis of splenic vein to renal vein to relieve portal hypertension. (12 Dec 1998) |
| distal splenorenal shunt | Anastomosis of the splenic end of the divided splenic vein to the left renal vein. Synonym: distal splenorenal shunt. (05 Mar 2000) |
| aortocoronary bypass | Vein grafts or other conduits shunting blood from the aorta to branches of the coronary arteries, to increase the flow beyond the local obstruction. Synonym: aortocoronary bypass. (05 Mar 2000) |
| aortoiliac bypass | An operation in which a vascular prosthesis is united with the aorta and iliac artery to relieve obstruction of the lower abdominal aorta, its bifurcation, and the proximal iliac branches. (05 Mar 2000) |
| aortorenal bypass | Insertion of a graft of autogenous artery, saphenous vein, or synthetic material between the aorta and the distal renal artery, to circumvent an obstruction of the renal artery. (05 Mar 2000) |
| bowel bypass | A surgical procedure consisting of the anastomosis of the proximal part of the jejunum to the distal portion of the ileum, so as to bypass the nutrient-absorptive segment of the small intestine, to treat morbid obesity. (12 Dec 1998) |
| bowel bypass syndrome | <syndrome> Fever, chills, malaise, and inflammatory cutaneous papules and pustules on the extremities and upper trunk, sometimes with polyarthralgia, with recurrent symptoms following bowel bypass surgery. (05 Mar 2000) |
| bypass | 1. A shunt or auxiliary flow. 2. <surgery> To create new flow from one structure to another through a diversionary channel. A by-passage, for a pipe, or other channel, to divert circulation from the usual course. See: shunt. Source: Websters Dictionary (20 Jun 2000) |
| bypass graft | <surgery> An alternative blood vessel that is created by a surgeon to reroute blood flow. Grafts may be synthetic (dacryon) or autologous (a vein from the patients own leg used as a substitute for the diseased vessel). (20 Mar 1998) |
| cardiopulmonary bypass | <procedure> This refers to the placement of the patient onto extracorporeal membrane oxygenation to bypass the heart and lungs as, for example, in open heart surgery. This device takes blood from the body, diverts it through a heart-lung machine (a pump-oxygenator) which oxygenates the blood prior to returning it to the systemic circulation under pressure. The machine does the work both of the heart (pump blood) and the lungs (supply red blood cells with oxygen). This allows the surgeon adequate time to perform primary heart surgery on a temporarily nonfunctioning heart. (20 Jun 1998) |
| gastric bypass | Surgical procedure in which the stomach is transected high on the body. The resulting proximal remnant is joined to a loop of the jejunum in an end-to-side anastomosis. This procedure is used frequently in the treatment of morbid obesity. (12 Dec 1998) |
| partial ileal bypass | Division of the small intestine approximately at the junction of the middle and lower one-third, closure of the distal end, and anastomosis of the proximal end to the caecum. (05 Mar 2000) |
