To address these challenges, the use of physician-modified endografts in which fenestrations are manually created by physicians has been reported. This approach, known as fenestrated and branched endovascular aortic repair, involves the placement of small-diameter bridging stent grafts through the fenestrations, and its utility has recently been highlighted.

Among 352 patients, 27 were classified as very elderly. Compared to younger cohorts, this group exhibited a higher prevalence of DeBakey typeⅡ dissection and thrombotic false lumen occlusion, with a lower incidence of malperfusion. The majority underwent hemiarch replacement. In-hospital mortality was low at 3.7%, and postoperative complication rates were comparable to the control group.
