A 35 year-old male with Marfan's syndrome was referred with a fortuitous echographic finding of an abdominal aorta flap. Transthoracic echocardiography showed moderate aortic regurgitation and an aneurysm in the sinus of Valsalva. Computed tomography demonstrated an aneurysm in the sinus of Valsalva 60 mm in size and a DeBakey type IIIb dissection extending from the left subclavian artery to the right common iliac artery. An aortic valve-sparing operation (reimplantation), total aortic arch replacement and the elephant trunk method were used in this patient. An aortic valve-sparing operation is preferable because the patient is young, and has no need for anticoagulant therapy after surgery. The extent of the aortic reconstruction, including the intact aortic arch, was appropriate to prohibit future dilatation of the aortic arch and retrograde dissection from a DeBakey type IIIb dissection.
一名35岁患有马凡氏综合征的男性因偶然的超声心动图检查发现腹主动脉瓣而前来就诊。经胸超声心动图显示中度主动脉瓣反流以及主动脉瓣窦瘤。计算机断层扫描显示主动脉瓣窦有一个60毫米大小的瘤,还有一个从左锁骨下动脉延伸至右髂总动脉的DeBakey IIIb型夹层。该患者接受了保留主动脉瓣手术(再植入)、全主动脉弓置换术和象鼻手术。由于患者年轻且术后无需抗凝治疗,所以保留主动脉瓣手术是首选。包括完整主动脉弓在内的主动脉重建范围足以防止未来主动脉弓扩张以及DeBakey IIIb型夹层逆行剥离。
