AbstractThe aim of this study was to report the case of a patient with chronic dissecting infrarenal abdominal aortic aneurysm (AAA) and to review the literature for this rare vascular disorder. The preoperative assessment, surgical treatment, and postoperative course of a patient with a dissecting AAA and associated left iliac artery dissection were analyzed. The literature is reviewed with respect to etiology and pathogenesis as well as diagnostic and therapeutic management of infrarenal dissecting AAA. The preoperative diagnosis of dissecting infrarenal AAA was made by computed tomography and aortography and confirmed during surgery. Successful repair was accomplished by use of a bifurcated aortobiiliacal Dacron graft. A review of the literature demonstrates the rarity of dissecting aneurysm exclusively involving the infrarenal aortic segment. Primary dissecting aneurysm of the infrarenal abdominal aorta is a rare morphologic finding. Principles of diagnostic and therapeutic management of common atherosclerotic AAA also apply to dissecting AAA.
