title: Incidence of coronary artery by-pass graft following percutaneous transluminal coronary angioplasty.
abstract: Two hundred fifty eight patients had percutaneous transluminal coronary angioplasty. Of those, 48 cases underwent surgical revascularization for unsuccessful angioplasty. Sex was not a risk factor. Timely surgical revascularization reversed acute ischemia and/or myocardial infarction or limited the size of the infarction in 32 of the 48 patients or 67%. Revascularization procedures were performed in six out of forty-eight patients who had previous aortocoronary by-pass surgery and attempted PTCA, none had any complications. Death occurred in one out of forty-eight patients, or 2%. Femoral-femoral by-pass devices, in addition to intra-aortic balloon devices, should be available in the cardiac catheterization laboratory. Patients with multi-vessel disease are at greater risk of angioplasty and surgery. Sixteen out of 23 patients (70%) who had emergency revascularization procedures had multi-vessel disease. In one patient with borderline renal function, emergency surgery after PTCA with a large amount of renograffin dye injected caused renal failure and led to permanent dialysis.
