Fenestrated-branched endovascular repair (FB-EVAR) has been widely applied to treat chronic post-dissection thoracoabdominal aortic aneurysms (TAAAs) with favorable outcomes. A recent multicenter experience indicates that outcomes of FB-EVAR for chronic post-dissection are comparable to degenerative TAAAs. Anatomical and technical pitfalls are different than degenerative aneurysms because of true lumen compression, separate target vessel origin from true or false lumen and possible extension of dissection flaps into the renal and mesenteric vessels. This article focuses on planning and sizing FB-EVAR in patients with chronic post-dissection TAAAs.
