The majority of infrarenal abdominal aortic aneurysm (AAA) repairs in the United States are performed with endovascular methods. Baseline aortoiliac arterial anatomic characteristics are fundamental criteria for appropriate patient selection for endovascular aortic repair (EVAR) and key determinants of long-term success. We evaluated compliance with anatomic guidelines for EVAR and ...

Clinical experience with coronary stent implantation in children is very limited. In-stent restenosis, thrombosis, and aneurysm formation are known complications. Recently, fracture of a drug-eluting stent was reported to be a cause of in-stent restenosis, but the natural course of stent fracture and proper management options remain uncertain. This report ...

The optimum time to treat abdominal aortic aneurysms (AAAs) still remains an uncertain issue. The decision to intervene does not take in account the effects that wall curvature, intraluminal thrombus (ILT) properties and thickness have on rupture. The role of ILT in aneurysm dynamics and rupture has been controversial. In ...
