Use of the inferior epigastric artery for coronary bypass.

摘要: Between December 1988 and April 1991, 74 free inferior epigastric arteries were used in 73 patients for coronary artery bypass grafts. In addition, 72 of the received a left internal mammary single or sequential grafting to anterior descending system 62 right circumflex artery. Twenty-seven had no saphenous vein available, two suitable artery; an attempt make complete arterial revascularization, we chose as alternative conduit 24 young 10 reoperations; bilateral dissection was avoided four with impaired lung function six selected two-vessel disease spare one The technique harvesting is described. Fifty-three grafts anastomosed distal its branches, 18 obtuse marginals (three natural Y graft), three system. mean number anastomoses 3.60 per patient. Seventy proximal made aorta There early deaths nonfatal myocardial infarction. Four abdominal wound hematomas needed surgical drainage. Sixty-one underwent angiographic study on postoperative day 10:59 61 (63 65 anatomoses) 111 (155 156 anastomoses) patent. Clinical follow-up all survivors (100% follow-up) could be obtained period 9 months (1 28 months). late cardiac death, infarction, angina. Nineteen 6-month study. Seventeen 19 patent 16 intact; 34 (46 47 intact. conclusion, can reach diaphragmatic ischemic areas heart. patency rate clinical results are encouraging but only long-term evolution evaluation determine true efficacy graft reliable operations.
