The ring technique for end‐to‐side microvascular anastomosis employs a resorbable polyglycolic acid ring to prevent stenosis and spasm at the anastomotic site. In 20 rats, the ring technique was compared with the conventional technique for constructing end‐to‐side anastomoses between the femoral (0.9‐1.1 mm) and superficial epigastric (0.3‐0.4 mm) arteries. The ring technique proved superior to the conventional end‐to‐side technique both in speed of execution and in patency at 3‐4 weeks (100% vs 70%). Grossly and microscopically, the ring was completely resorbed at 3 wk.
