Endovascular repair of dissecting thoracoabdominal aneurysms (TAAA) is challenging and often requires multiple procedures. A 61-year-old man with a dissecting type-II TAAA treated first by placement of a thoracic endograft, and subsequently implantation of a fenestrated endograft. Six months postoperatively, a 10-mm increase of the aorta was observed. A reentry tear in left external iliac artery (EIA) was perfusing the false lumen in a retrograde fashion connecting with the endoleak caused by the inferior mesenteric artery and lumbar arteries. False lumen embolization of the left EIA and outflow vessels was performed. Thrombosis and rapid decrease of false lumen diameter was then observed. This case illustrates the complexity of endovascular management of extensive chronic aortic dissections.
