Annuloaortic ectasia associated with severe aortic regurgitation is usually managed by implanting a composite graft that comprises both valve and conduit. Synthetic valved conduits have been used by most cardiovascular surgeons, with various modifications in the technique. Yet prosthetic valves carry the risks associated with anticoagulation therapy, together with an increased risk of infective endocarditis. We report a case in which a cryopreserved aortic homograft was used for a Bentall procedure in a patient who had annuloaortic ectasia with severe aortic regurgitation. To the best of our knowledge, there are no prior published reports of homograft insertion in treatment of annuloaortic ectasia.
与严重主动脉瓣反流相关的主动脉根部扩张通常通过植入包含瓣膜和管道的复合移植物来治疗。大多数心血管外科医生使用合成带瓣管道，并在技术上进行了各种改进。然而，人工瓣膜存在抗凝治疗相关风险，以及感染性心内膜炎风险增加的问题。我们报告了一例使用冷冻保存主动脉同种异体移植物为患有主动脉根部扩张伴严重主动脉瓣反流的患者进行Bentall手术的病例。据我们所知，此前尚无关于同种异体移植物植入治疗主动脉根部扩张的报道。
