Arteriosclerotic femoral artery aneurysms are relatively uncommon, but they are the second most commonly encountered peripheral arterial aneurysm. The exact incidence of femoral artery aneurysms in the general population has not been defined, but they are nearly as common as…

Large-caliber prostheses used for aortic replacement initiate blood–material interfacial processes that begin almost immediately upon establishment of circulatory flow. These processes lead to prosthetic encapsulation and structural alteration, occasionally a degree of degradation of synthetic polymers, and ultimately these events…
The traditional repair of isolated iliac artery aneurysms (IAAs) has been through an open surgical approach. The pelvic location of the isolated iliac aneurysm can increase the technical difficulty of open repair. The operative mortality for open elective repair of…
The Ad Hoc Committee on Reporting Standards of the Society for Vascular Surgery and the International Committee on Reporting Standards of Cardiovascular Surgery, North American Chapter, define iliac artery aneurysms (IAAs) as any permanent localized dilation of the iliac artery…

Acute aortic dissection causes death by rupture of the false lumen or by end-organ malperfusion. Untreated acute type A dissection has a mortality of approximately 50% within 48 hours, predominantly caused by rupture resulting in cardiac tamponade. Acute type B…
Acute aortic dissection should be considered a constituent of acute aortic syndrome (AAS) together with intramural hematoma (IMH), penetrating atherosclerotic ulcer (PAU), and aortic rupture. The common denominator of AAS is disruption of the media layer of the aorta, with…
The overlapping effects of aortic occlusion, collateral blood flow, metabolism, oxygen supply and demand, surgical technique, and response to ischemia underlie the unpredictability of spinal cord ischemia and subsequent paralysis in the surgical treatment of thoracoabdominal aortic aneurysms (TAAAs). However,…
Aneurysms involving the thoracoabdominal aorta are uncommon, but they receive significant attention due to their complexity of repair and risk of end-organ impairment. Advances in preoperative planning, surgical technique, anesthesia, and postoperative management have led to improved outcomes, most notably…
