The authors have seen four cases of asymptomatic delayed intimal injury adjacent to a stent graft diagnosed 7 to 16 months after thoracic endovascular aortic repair. Endovascular repeat intervention was successfully performed in three of the four cases as described in the present report. A second consecutive "intimal blowout" in one patient remains under close radiologic surveillance. Possible causes for the intimal blowouts, including stent-graft size, landing zone anatomy, and intrinsically weak aortic tissue, are discussed.
作者观察到 4 例胸主动脉腔内修复术后 7 至 16 个月无症状的支架移植物相邻部位延迟性内膜损伤。本报告介绍了其中 3 例在 4 例中成功进行了血管内重复介入治疗。1 例患者仍在密切进行放射影像学监测，以观察是否会再次出现连续的“内膜爆裂”。讨论了内膜爆裂的可能原因，包括支架移植物大小、着陆区解剖结构和固有脆弱的主动脉组织。
