目的：探讨改良Cabrol 分流在升主动脉人工血管置换中的临床疗效。方法：收集2002 年9 月至2009 年12 月升主动脉人工血管置换术共72 例，其中行改良Cabrol 分流为39 例(GroupⅠ)、瘤壁包裹人工血管不分流和完全剔除瘤壁不分流为31 例为31 例(GroupⅡ)。计算两组术后24h、48h 的心包纵隔引流量并进行统计学分析，并对Cabrol 分流的病人在术后1 周和3 月行心脏超声心动图检查了解是否有分流存在。结果：术后24h、48h 心包纵隔引流量引流量GroupⅠ＜GroupⅡ，差异有统计学意义。Cabrol 分流的病人在术后1 周行心脏超声心动图检查有2 例存在分流信号，术后3 月复查分流消失。结论：改良Cabrol 分流在升主动脉人工血管置换术中能显著降低术后出血量，对注射鱼精蛋白后吻合口仍有明显渗血的病例在术中应预防性采取分流术，无相关并发症发生，可取得满意的止血效果,远期效果尚待观察。

英文摘要:

Objective: To evaluate the clinical effect of modified Cabrol shunt. Methods: Collect seventy-two patients undergoing the replacement of ascending aortic graft during September 2002 to December 2009. Calculate pericardium-mediastina drainage volume of patients underwent modified Cabrol shunt/fistula technique (GroupⅠ), inclusion/wrap technique and button open technique (GroupⅡ), postoperative twenty-four hours and forty-eighty hours, carry out statistics analysis. The patients of GroupⅠwas checked by echocardiography to explore shunts postoperative one week and three months. Results: There were two operative deaths resulted from refractoriness ventricular chill, two patients was re-opened thoracic cavity for homeostasis. Between groups Ⅰ and Ⅱ, a significant difference was found in postoperative bleeding. Analysis showed that the drainage Group Ⅰ＜Group Ⅱ . The patients performed modified Cabrol shunt were examed by echocardiography postoperative one week and three months respectively, of two patients proved shunt at one week but then disappeared at three months. Conclusion: The modified Cabrol shunt in the replacement of ascending aortic graft can cut down the postoperative haemorrhage notably, for those cases of anastomosis errhysis after injected Protamin shouled be performed prophylactic shunt, it proved gained satisfactory hemostasis without correlated complacations,then long-term effect still to wait for oberservation.
