Side-to-side anastomosis using 4 interrupted sutures in small coronary arteries

Side-to-side anastomosis in sequential bypass grafting of coronary arteries 1.0 mm in diameter or smaller, requires delicate surgical techniques with a high degree of technical difficulty. However, using only 4 interrupted sutures, we have performed side-to-side anastomosis in sequential grafting without difficulty in a short operative duration. We applied this technique in 58 distal anastomosis procedures, achieving an early angiographic graft patency rate of 100%.
