Abstract

Aim: The aortic valve-sparing procedure is an elective option for patients with aortic aneurysms. The feasibility of the surgical method in treating acute type A aortic dissection is still controversial. We aimed to study the outcomes of the David V aortic valve-sparing root replacement procedure.

Methods: We studied 21 acute type A aortic dissection patients who received the David V re-implantation technique. Patients were followed up with annual postoperative echocardiograms. Follow-up was 100% complete, with a mean duration of 40 ± 26 months.

Results: In 15 (71%) patients, the David V re-implantation technique was performed together with hemiarch; in 6 (29%) patients, it was combined with total aortic arch replacement. Three (14%) patients died in the hospital. None of the patients developed aortic regurgitation (AI) greater than second-degree at discharge. One patient had 2+ AI during the follow-up period, and the others showed trace/no AI.

Conclusion: The David V operation can be considered for younger patients with suitable anatomy for acute type A aortic dissection with favourable outcomes.

保留瓣膜的主动脉根部置换术治疗急性A型主动脉夹层。

目的：保留主动脉瓣手术是动脉瘤患者的一种选择性手术。手术治疗急性A型主动脉夹层的可行性仍存在争议。我们的目的是研究David V保留主动脉瓣的根置换手术的结果。方法：对21例急性A型主动脉夹层患者行David V瓣再植入术。术后每年随访超声心动图。随访100%完成，平均随访时间40±26个月。结果：15例（71%）患者行David V再植入术时伴有出血；6例（29%）患者联合全主动脉弓置换术。3例（14%）患者在医院死亡。所有患者出院时均无主动脉瓣反流（AI）大于二级。1例患者随访期间AI为2+，其余患者为微量/无AI。结论：年龄较轻、解剖结构适宜的急性A型主动脉夹层患者可考虑行David V手术，手术效果良好。
