A Rare Catastrophe: Three Cases of Aortic Root Dehiscence after Surgery

Abstract Ascending aortic pathologies may be life-threatening. Postoperative aortic root dehiscence is a very rare but extremely dangerous complication with a high mortality rate, and redo surgery is mandatory due to high risk of spontaneous rupture. We present three cases that had undergone Bentall procedure and had postoperative aortic root dehiscence. One of the patients presented with hemiplegia caused by septic embolus while the others had mild symptoms. Dr. Yakut’s modified Bentall procedure, the flanged technique, was performed for each patient in redo surgery. Two patients were successfully discharged from the hospital, but one died due to intracranial hemorrhage and multiple organ failure.摘要 升主动脉病变可危及生命。术后主动脉根部裂开是一类极为罕见却极具危险性的并发症，病死率较高，且因自发破裂风险极高，需行再次手术治疗。本文报告3例曾接受本塔尔手术（Bentall procedure）后出现术后主动脉根部裂开的病例：其中1例患者因脓毒性栓子引发偏瘫，其余2例症状相对轻微。所有患者的再次手术均采用亚库特改良本塔尔手术的带缘技术（flanged technique）。最终2例患者顺利出院，1例因颅内出血及多器官功能衰竭死亡。
