Presentation
Previous history of surgery for aortic valve and proximal aortic endograft.
Patient Data
There is a descending aortic dissection that begins beyond the brachiocephalic vessels (Stanford B) and only involves the descending aorta (DeBakey type III). Note also the presence of the aortic valve prosthesis and a small proximal endoleak related to the Dacron graft on ascending aorta (not seen on enhanced series).
The celiac and superior mesenteric arteries both arise from the smaller true lumen.
Case Discussion
There is a descending aortic dissection that begins beyond the brachiocephalic vessels (Stanford B) and only involves the descending aorta (DeBakey type III).
