Malperfusion in any territory at the time of presentation in patients with type B dissections can be treated with endovascular intervention with acceptable outcomes. Opposed to branch vessel intervention alone, increased aortic intervention with regard to proximal coverage may signify more serious disease is associated with worse outcome.
Background: Stent graft infection is a rare but serious complication in patients who underwent endovascular aortic aneurysm repair. Particularly removal of suprarenal fixing stent graft carries risk of aortic or renal artery injury. There have been reported several options of aortic reconstruction after successful removal of infected device.Technical Description: 1. Exposure of aorta and proximal and distal control. 2. Removal of aortic stent graft with syringe technique which include preparation of syringe, exposure of stent graft, removal of stent graft. 3. Preparation of cyropreserved aortic and arterial allografts: thawing and rinsing of cryopreserved arterial allografts, composition of allografts to make bifurcated aortic graft. 4. In situ aortic reconsctruction: aorto-iliac reconstruction and graft omentum wrapping of the grafts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
