| 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) |
| right heart bypass | Introduction of a circuit shunting blood from the venae cavae around the right atrium and ventricle and directly into the pulmonary artery. (05 Mar 2000) |
| coronary artery bypass | Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion. (12 Dec 1998) |
| coronary artery bypass graft | A surgical procedure, known as a coronary artery bypass graft, which involves replacing diseased (narrowed) coronary arteries with veins obtained from the patients lower extremities (autologous graft). During this procedure the patient is placed on a heart bypass machine (heart-lung machine) to allow the surgeon adequate time to perform surgery on the resting (nonbeating) heart. This procedure has proven to extend the lives of individuals with coronary artery disease and improve the quality of life. Recovery in the hospital is approximately 7-10 days. (27 Sep 1997) |
| coronary 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) |

| heart bypass, left | Diversion of the flow of blood from the pulmonary veins directly to the aorta, avoiding the left atrium and the left ventricle. This is a temporary procedure usually performed to assist other surgical procedures. (12 Dec 1998) |
| heart bypass, right | Diversion of the flow of blood from the entrance to the right atrium directly to the pulmonary arteries, avoiding the right atrium and right ventricle. This a permanent procedure often performed to bypass a congenitally deformed right atrium or right ventricle. (12 Dec 1998) |
| septic bursitis. Bypass | An operation in which the surgeon creates a new pathway for the movement of substances in the body. (12 Dec 1998) |
| jejunoileal 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) |
| extra-anatomic bypass | A vascular bypass that does not conform to the preexisting anatomy. (05 Mar 2000) |
