Ischemic complications after endovascular abdominal aortic aneurysm repair.

Objectives: Limb and pelvic ischemia are known complications after endovascular abdominal aortic aneurysm repair (EVAR). The objective of this paper is to present our experience with the incidence, presentation, and management of such complications.

Methods: Over 9 years 311 patients with aortic aneurysms underwent EVAR.

Improved patency of prosthetic arteriovenous grafts with an acute anastomotic angle and flow diffuser.

Objective: Conventional end-to-side anastomosis to establish venous outflow for prosthetic arteriovenous grafts often requires operative patch angioplasty within 1 year because of venous stenosis. Rather than conventional venous anastomosis, a modified end-to-side anastomosis at a 15-degree angle with a flow diffuser was constructed. Such diffusers allow decreased flow velocity and increased pressure, inhibiting boundary layer separation.
