Coronary revascularization with the radial artery: new interest for an old conduit.

摘要: Between July 1992 and May 1994, 148 patients (18 females) underwent myocardial revascularization with a radial artery (RA) graft. The left RA was used in 97.3% of cases. All but two received at least one additional arterial conduit: 137 59 right internal mammary arteries (IMA); 23 inferior epigastric arteries; 21 gastroepiploic arteries. Total achieved 127 (85.8%). An average 3.0 anastomoses/patient were constructed, 2.8 which arterial. proximal anastomoses placed on the IMA 75% cases, while direct anastomosis to aorta (23.7%) or saphenous vein (1.3%) performed remainder. When anastomosed an IMA, subsequently infused intraluminally 10 mg papaverine (1 mg/mL). target anterior descending its branches 14.7% circumflex system 76.3%, native coronary remaining 9%. infusion diltiazem (4 mg/hour) started once unclamped, maintained oral for 6 months postoperatively. Operative mortality 1.4% (2 patients), late deaths from noncardiac causes. In patient there prolonged serous drainage donor site. Of 144 survivors 140 are asymptomatic. Follow-up angiography demonstrated 100% early patency (< 30 days, 41 94% (6 20 months, mean 14 30/32 patients). This study suggests can be safely as alternative bypass surgery.(ABSTRACT TRUNCATED AT 250 WORDS)
