We report a case of a type A aortic dissection with extension into the main pulmonary artery through a sinus of Valsalva fistula. Echocardiography and computed tomographic angiography of the chest were performed and bicuspid aortic valve, hemopericardium, and dilatation of the aortic root were found. A Stanford type A dissection was seen, extending to the distal transverse thoracic aorta, and there was a communication between the dissection at the left sinus of Valsalva and the main pulmonary artery, where a dissection flap was detected at computed tomographic angiography. This case report reviews the rare diagnosis of pulmonary artery dissection, multimodality imaging findings, and a brief review of etiology and management.
我们报告一例A型主动脉夹层经瓦氏窦瘘延伸至主肺动脉的病例。进行了胸部超声心动图和计算机断层血管造影检查，发现了二叶式主动脉瓣、心包积血和主动脉根部扩张。可见Stanford A型夹层，延伸至胸段降主动脉远端，在瓦氏窦左窦处的夹层与主肺动脉之间存在交通，计算机断层血管造影检查发现了一个夹层瓣。本病例报告回顾了肺动脉夹层的罕见诊断、多模态影像学表现，并简要回顾了病因及治疗。
