Free (aorta-coronary) internal mammary artery graft: Late results

摘要: Free internal mammary artery grafts were placed in 156 patients (1971 to 1985). Preoperative clinical and angiographic variables similar those of other series isolated coronary bypass grafts. Of 244 total grafts, 166 the aorta-coronary position performed mainly because unsuitable saphenous veins or gain additional graft length. One patient (0.6%) died during hospitalization. Perioperative complications included respiratory dysfunction 16 (10.3%), reoperation for bleeding 13 (8.0%), stroke four (2.6%), myocardial infarction three (1.9%), wound two (1.3%). Morbidity occurred significantly more often 1971 1975 period. Subsequently, eight (7%) had (6 158 months; mean 99 months). After a 98 month follow-up, 10 year actuarial survival rate (including all causes death) was 73.3%. 40 free restudied within 18 months operation, 31 (77%) patent The higher early closure is attributed technical problems our experience, especially construction aortic anastomosis. However, 32 35 (91%) studied after than (mean 94 months) open. Fifty 58 (86%) anterior descending artery, seven nine (78%) circumflex, six (75.0%) right Sequential catheterization showed that 24 open at 9 months, remained 80 when these 93 (third catheterization) (fourth 125 These late studies no evidence atherosclerosis. like situ appear have relative immunity from findings expand versatility grafting justify wider use
