Arteriovenous fistula as adjuvant treatment in arterial revascularization of an at-risk limb.

Acute arterial occlusion remains a major challenge for the vascular surgeon. The therapeutic approach depends mostly upon the severity of the tissue injury and the duration of symptoms. Several techniques are available in the current therapeutic arsenal, however, regardless of the technique chosen, postoperative factors frequently observed, such as poor outflow status, or even low graft flow, can contribute negatively to the outcome of revascularization.

The outcomes of internal iliac artery preservation during endovascular or open surgery treatment for aortoiliac aneurysms.

Background: Internal iliac artery (IIA) preservation continues to be a challenge during open surgery or endovascular repair of abdominal aortoiliac aneurysm (AAIA).

Objectives: To determine the results in terms of survival and clinical outcomes in patients with aortoiliac aneurysms (AAIA) treated with endovascular (EV) or open surgical (OS) repair.

Methods: This was a retrospective consecutive cohort study of patients with AAIA who underwent EV or OS repair.

Alternative iliofemoral revascularization in extensive aortoiliac occlusive disease.

Over recent decades, there has been a considerable increase in use of endovascular methods to treat aortoiliac occlusive disease. It has been demonstrated that this approach offers many benefits, primarily for non-complex arterial lesions of the iliac axis, but difficulties persist with achieving adequate results over the medium and long term when treating extensive occlusive disease. Arterial bypasses to alternative vicarious arteries of the femoral-genicular complex for limb salvage are well known in the literature describing cases that are not favorable for conventional or endovascular surgery.
