ABSTRACT
In the era of catheter intervention, the surgical repair of coronary arteriovenous fistula needs to be free from residual shunt. Intraoperative epicardial 15-MHz echocardiography helps to find the residual shunt after ligation or obliteration of anomalous vessels. Here we report our method of the echo-assisted surgical repair of coronary arteriovenous fistula in 7 adult patients. The method made the operation for coronary arteriovenous fistula free from residual shunt, but care should be taken to the development of new vessels after the operation.

In this study, we present an inexpensive and effective method for providing a secure and hemostatic anastomosis using autologous adventitia obtained from a dissected or aneurysmal wall. The resected aortic wall is separated between the adventitia and media, and a soft, 2 × 10-cm adventitial strip is overlaid to cover the anastomotic margin. A graft is sutured to the aortic stump. This autologous adventitial overlay method can inexpensively and strongly reinforce the anastomosis during aortic surgery for dissection or aneurysm and will contribute to anastomotic hemostasis and long-term stability.
