Hemostasis during aortic root replacement with a composite graft, consisting of a separate Dacron graft and a valve, was markedly improved by using a supra-annular aortic wall reinforcing suture (SAWR). Between February 1994 and January 1998, 14 consecutive patients (10 men and 4 women) underwent replacement of the aortic valve and ascending aorta with the SAWR technique. No intraoperative bleeding of the aortic proximal suture line or early death occurred in this group. No patient required reoperation for bleeding of anastomoses. Three of 10 patients who underwent elective operations were operated on successfully without blood transfusion. In addition, no clinical complications related to the SAWR technique were observed in the follow-up period. We conclude that the SAWR technique can be performed easily and may be an effective method for improving proximal hemostasis.
采用由单独的涤纶移植物和瓣膜组成的复合移植物进行主动脉根部置换时，使用瓣环上主动脉壁加强缝合术（SAWR）可显著改善止血效果。1994年2月至1998年1月期间，连续14例患者（10例男性和4例女性）采用SAWR技术进行主动脉瓣和升主动脉置换。该组患者术中主动脉近端缝合线无出血情况，也无早期死亡病例。没有患者因吻合口出血而需要再次手术。10例接受择期手术的患者中有3例成功手术，术中未输血。此外，在随访期间未观察到与SAWR技术相关的临床并发症。我们得出结论，SAWR技术操作简便，可能是改善近端止血的有效方法。
