【摘要】 目的探讨行手术治疗的单纯主动脉瓣反流病因分布。方法手术治疗的单纯主动脉瓣重度反流患者86例,通过超声心动图观察主动脉瓣反流、瓣膜形态及异常回声、升主动脉内径,综合超声心动图、手术所见、部分病理结果和临床资料确定最终病因。结果在手术治疗单纯主动脉瓣反流患者中,瓣膜松弛、感染性心内膜炎和升主动脉夹层分别排行前3位病因。风湿性心脏病、退行性变、白塞病排行并列第4位。其余病因为主动脉瓣二叶瓣和梅毒。结论本组行手术治疗的单纯主动脉瓣反流病人中,病因以瓣膜病为主,超声心动图在确定病因方面起重要作用。更多还原

【Abstract】 Objectives To analyse pathogeny of aortic regurgitation treated with operation. Methods Echocardiographic examination was performed in eighty-six patients with middling-severe aortic regurgitation treated by operation. Echocardiographic examination included aortic regurgitation,valvular modality and ascending aorta dimension. Pathogeny diagnosis was performed by echocardiographic and surgery data. Results Pathogeny of aortic regurgitation included valvular slack,infection indocarditis,aortic dissection,rheumatic,recessive,Behcet disease,other few reason resulted from bicuspid arotic valve,syphilis in high to low order. Conclusions Valvular slack leads pathogeny of aortic regurgitation in patient treated with operation. Echocardiography plays an important role in diagnosis of pathogeny of aortic regurgitation.更多还原
