【摘要】 主动脉根部替换术是保留主动脉瓣的主动脉根部病变合并主动脉瓣关闭不全的最佳治疗方式,其中David手术是治疗该疾病的经典手术方式之一。David手术是在进行解剖性主动脉根部重建的基础上,保留患者的主动脉瓣,并对其进行修复和重新植入。本研究采用人工血管外套主动脉根部行David手术,该术式通过调整主动脉瓣叶的对合情况,消除瓣膜的返流,其严密的缝合技术还可减少术后出血,避免产生终身抗凝和机械瓣膜相关并发症,保证持久的主动脉瓣功能,提高患者的生存质量。更多还原

【Abstract】 Aortic root replacement is the best treatment for aortic root lesions combined with aortic regurgitation while preserving the aortic valve, and David’s surgery is one of the classic surgical methods for treating this disease. David’s surgery preserves the patient’s aortic valve on the basis of anatomical aortic root reconstruction and repairs and reimplants it. This study used an artificial blood vessel to sheath the aortic root to perform David’s surgery. This procedure eliminates valve regurgitation by adjusting the apposition of the aortic valve leaflets. Its strict suturing technique can also reduce postoperative bleeding, avoid lifelong anticoagulation and mechanical valve-related complications, ensure lasting aortic valve function, and improve the patient’s quality of life.更多还原
