摘　　要：目的总结一期全主动脉替换术治疗全程主动脉瘤的中期随访结果。方法2004年2月至2008年7月22例全程主动脉瘤的患者接受一期次全（7例）或全主动脉替换术（15例）。男性17例，女性5例，年龄19～47岁。慢性A型夹层动脉瘤15例，主动脉根部瘤合并慢性B型夹层动脉瘤5例，主动脉根部瘤合并弓部和胸腹主动脉瘤1例，慢性B型合并急性A型夹层动脉瘤1例。手术均在全身麻醉深低温停循环顺行性脑灌注下进行。采用胸骨正中切口＋左后外胸腹联合切VI。采用分段阻断法用人工血管置换全部病变主动脉。结果无手术死亡病例。术后早期死亡1例，死于多器官功能衰竭。术后发生脑梗死2例，二次开胸止血7例。存活21例，随访3～56个月，平均（35．0±16．9）个月，情况良好，无晚期死亡。1例David＋全主动脉替换术患者术后1年因主动脉瓣反流行主动脉瓣置换术。此外无再手术病例。结论一期次全或全主动脉替换术是治疗全程主动脉瘤的有效方法。手术结果满意，术后中期随访效果良好。Objective To summarize the experience of one-stage total and subtotal aortic replacement for aneurysm evolving the entire aorta and show the midterm results of the operation. Methods From February 2004 to July 2008, 22 patients （17 men and 5 women, age ranged from 19 to 47 years old） underwent one-stage total or subtotal aortic replacement under deep hypothermic circulatory arrest and selective antegrade cerebral perfusion. Seven patients received subtotal aortic replacement （from the aortic valve to the abdominal aorta）. Fifteen patients underwent total aortic replacement （from the aortic valve to the aortic bifurcation）. Patients were opened with a mid-sternotomy and a thoracoabdominal incision. First, the ascending aorta was replaced; following which the aortic arch was reconstructed. Finally, the thoracoabdominal aorta was fully replaced. Results Thirty-day mortality was 4. 5% （ 1/22 ）. One patient died of multiple organ failure 11 days postoperatively. Two patients had cerebral infarction secondary to embolism. Spinal neurological deficits didn＇t occur. Twenty-one patients survived the operation and were followed up for 3 to 56 months （35.0±16.9 months）. There was no late death. One patient received aortic valve replacement due to aortic valve regurgitation one year after David and total aortic replacement. Conclusion One-stage total and subtotal aortic replacement is an effective operation for aneurysm evolving the whole length of the aorta with acceptable mortality and morbidity. Midterm follow-up showed satisfactory results.
