ステントグラフト(SG)による再解離(SINE)は,一般に大動脈解離に対する胸部ステントグラフト内挿術(TEVAR)の合併症として知られている.われわれは,慢性解離性胸部大動脈瘤に対するオープンステントグラフト(OSG)法を用いた全弓部大動脈置換術後にSINEを起こした症例を経験したので,若干の文献的考察を加えて報告する.
A 68-year-old woman after total arch replacement with open stent graft (OSG) technique for aneurysmal chronic Stanford type B aortic dissection was found to have expanding proximal descending aortic aneurysm. Contrast-enhanced computed tomography (CT) showed distal stent graft-induced new entry (distal SINE). We successfully performed additional thoracic endovascular aortic repair (TEVAR). There were no complications and the postoperative course was uneventful. We should take utmost care in selecting surgical procedures with OSG technique for aneurysmal chronic Stanford type B aortic dissection.
