改良Bentall术对马凡综合征主动脉根部瘤的临床治疗效果

Modified Bentall operation on clinical therapeutic effect of Marfan~ syndrome of aortic root aneurysm

目的：研究“改良Bentall手术”在治疗马凡综合征主动脉根部瘤疗效情况。方法：2000年5月--2011年6月，共有54例的马凡综合征主动脉根部瘤的患者接受治疗。其中，A组24例接受普通Bentall术，B组30例接受改良Bentall术，对比2纽的疗效。结果：A组患者死亡数2例（8．4％），B组没有死亡的病例。B组术中比A组失血量少，P〈0．01，具有统计学差异。与A组相比，B组患者的主动脉转机时间、阻断时间和手术操作的时间较短，P〉0．05，无统计学差异。B组患者在术后的10小时引流少于A组，P〈0．01，具有统计学差异。B组患者的围术期悬浮的红细胞注射量比A组的少。抽查时间3—90个月，A、B组均没出现死亡的病例。结论：改良Bentall术可以使患者在手术中失血量减少，手术的时间缩短，中期抽查疗效好，对马凡综合征主动脉根部瘤治疗，安全性好。

Objective： To study ＂of modified Bentall operation＂ in the treatment of Marfan syndrome with aortic root aneurysm treat- ment. Methods： from 2000 May ~2011 year in June, a total of 54 cases of Marfan syndrome with aortic root aneurysm patients treated. Among them, 24 eases in group A underwent conventional Bentall surgery, B group of 30 patients received modified Bentall operation, the curative effect were compared between the two groups. Results： in A group, 2 cases of death （8.4%）, B group had no death cases. Pa- tients in group B than in group A were less blood loss, p 〈 0.01, with statistical difference. Compared with group A, group B patients with aortie cross clamping time and turnaround time, operation time is short, P 〉 0.05, no statistical difference. Patients in the B group than in A group in drainage, postoperative lOh p 〈0.01, with statistical difference. Red cell injection group B, perioperative patients with sus- pension of less than A group. Sampling time of 3 to 90 months, A, B groups were no deaths. Conclusion： modified Bentall operation could make the patients in operation blood loss, operation time might be shortened, the mid drainage Good effect of Marfan syndrome, aor- tic root aneurysm treatment, good safety.
