title: Surgical A-V fistula in aortocoronary snake graft. Preliminary report.
abstract: In coronary artery surgery, when a poor distal run of can predict an early graft failure, it might be useful to perform the last anastomosis to a low pressure chamber thus creating a small arterio-venous (A-V) fistula. From January throughout December 1984, 4 patients underwent coronary angiography for severe symptoms of angina. The coronary angiography showed multiple stenoses on the left anterior descending (LAD), ventricular branches of the circumflex (CX), and posterior descending of the right coronary artery (PD). At operation the patients received a sequential aortocoronary bypass graft with reversed saphenous vein, plus the creation of a small A-V fistula into the right atrium in order to improve the graft flow and patency. All patients experienced a clinical improvement. No adverse effects have been observed and the patients, controlled clinically with non invasive and in two cases with invasive techniques, showed satisfactory revascularization.
