Abstract:
A 72-year-old man with suprarenal aneurysm and 2 large penetrating ulcers (PAUs) in the descending aorta was referred for endovascular treatment. To avoid long-segment aortic coverage and the attendant risk of spinal ischemia, combination of 2 different stent technologies was used. A multilayer flow modulator was implanted in the thoracic aorta for the PAU, followed by implantation of a customized 4-vessel fenestrated stent graft for the suprarenal aneurysm. The patient remained well at 2 years with computed tomography evidence of exclusion of the suprarenal aneurysm and involution of the PAU.
