A redo sternotomy, aortic root, and arch replacement in a patient following previous complex surgical and endovascular type A aortic dissection repair is presented in this video case report. Shortly after having the initial type A aortic dissection repair with replacement of the ascending aorta, the patient developed severe visceral malperfusion due to a compressed distal true lumen and underwent emergency endovascular repair with ascending arch and descending thoracic aorta stents and chimney grafts for the aortic arch vessels as well as fenestration of the intimal flap of the abdominal aorta. Unfortunately, the patient developed permanent paraplegia and progressive symptomatic severe aortic regurgitation. The patient underwent a redo sternotomy, aortic root, and arch replacement with explantation of the ascending stent graft and chimney stent grafts. Antegrade cerebral perfusion was maintained throughout the procedure. The aortic arch was replaced using a Terumo Aortic Plexus multibranched graft distally anastomosed to the endovascular stent graft, and the innominate and left common carotid arteries were reimplanted onto the graft. The aortic root was replaced with a Bioconduit graft, using a modified Cabrol technique to reimplant the left coronary artery. A satisfactory postoperative course and computed tomography imaging highlight the feasibility of this highly complex aortic arch repair with careful preoperative planning.
本文报告了 1 例先前接受过复杂手术和血管内治疗 A 型主动脉夹层修复的患者再次行胸骨切开、主动脉根部和弓部置换的病例。该患者初次行 A 型主动脉夹层修复,置换升主动脉,术后因远端真腔受压导致严重内脏灌注不良,紧急行血管内修复,升主动脉弓和降胸主动脉支架及烟囱支架置入,用于主动脉弓血管,腹主动脉内膜瓣开窗。不幸的是,患者发生永久性截瘫和进行性症状性严重主动脉瓣反流。患者再次行胸骨切开、主动脉根部和弓部置换,取出升主动脉支架和烟囱支架。整个手术过程中均保持顺行性脑灌注。使用 Terumo Aortic Plexus 多分支移植物,在远端与血管内支架移植物吻合,替换主动脉弓,无名动脉和左颈总动脉重新吻合到移植物上。使用改良的 Cabrol 技术,将主动脉根部替换为 Bioconduit 移植物,重新植入左冠状动脉。术后恢复顺利,计算机断层扫描成像突出了这种精心术前规划的高度复杂主动脉弓修复的可行性。
