Abstract

Two patients with chronic type B aortic dissection underwent endovascular repair. The interval between the onset of aortic dissection and stent grafting was 1 year, 7 months in both patients. The entry closure was successful and postoperative course was uneventful for each patient. However, intimal injury developed at the bottom end of the stent graft 6 years after endovascular repair in 1 patient, and at 2 years in the other patient. The former patient underwent graft replacement of the descending thoracic aorta, and the latter underwent placement of additional stent grafts.

摘要

两名慢性 B 型主动脉夹层患者接受了血管内修复。两名患者主动脉夹层发病至支架置入的间隔时间分别为 1 年 7 个月。腔内修复的入口封闭均成功，每位患者的术后过程均无异常。然而，1 名患者在血管内修复后 6 年，另 1 名患者在 2 年后，支架移植物的底部出现内膜损伤。前者接受了胸降主动脉移植物置换，后者接受了额外的支架移植物置入。
