Interposition graft method, total replacement of the ascending aorta with a valved conduit and reimplantation of the coronary artery by an interposed graft with some modifications, had been exclusively used for the treatment of aortic regurgitation associated with an aneurysm of the ascending aorta in consecutive 7 cases. Clinical improvement is apparent and postoperative angiographic study revealed a satisfactory coronary and aortic appearance with no leakage, pseudoaneurysm formation nor compression of the graft. This technique proved to be a reliable and safe method for the treatment of aortic regurgitation associated with an aneurysm of the ascending aorta with no mortality nor modality.
采用间置移植法，即用带瓣管道完全置换升主动脉，并通过间置移植对冠状动脉进行再植入并做了一些改进，连续7例升主动脉瘤合并主动脉瓣关闭不全患者均采用此方法治疗。临床改善明显，术后血管造影研究显示冠状动脉和主动脉外观良好，无渗漏、假性动脉瘤形成或移植物受压。该技术被证明是治疗升主动脉瘤合并主动脉瓣关闭不全的一种可靠且安全的方法，无死亡病例，也无并发症。
