[Optimal myocardial revascularization by coronary bypass and complementary angioplasty. Study of 100 patients].
One hundred patients underwent early coronary angiography (average 20.5 days) after coronary bypass surgery between 1994 and 1996. The indications in clinically asymptomatic patients were: study of double mammary grafts, non respect of the preoperative plan (grafts not available, technical difficulties), and/or postoperative ECG changes. 12.1% of internal mammary grafts and 18.2% of the saphenous vein grafts were considered to be non-fractional: due to occlusion in 3 and 11.9%, due to poor implantation site (persistence of a distal stenosis): 3 and 0.8% respectively. After investigations to detect ischaemia in the region concerned or persistence of a critical lesion on a non-revascularised main artery, 26 complementary angioplasties were performed: 3 on internal mammary grafts, 4 on saphenous vein grafts and 19 on the native vessels. Surgery alone resulted in complete revascularisation in 70% and its association with cardiological interventional techniques increased the value to 85%. The association of coronary bypass surgery and transluminal angioplasty may therefore result in optimal revascularisation. This should reduce the morbidity rate, the number of hospital admissions (recurrent ischaemia and reoperation) and improve survival. However, the exact modalities of this combined revascularisation remain to be defined.
