Duplex Ultrasound Surveillance After Uncomplicated Endovascular Abdominal Aortic Aneurysm Repair.

Objectives: Health-care costs and risks of radiation and intravenous contrast exposure challenge computed tomography angiography (CTA) as the standard surveillance method after endovascular abdominal aortic aneurysm repair (EVAR). We reviewed our experience using Duplex ultrasound scan (DUS) as an initial and subsequent surveillance technique after uncomplicated EVAR.

Methods: The medical records of patients who underwent EVAR from 2004 to 2014 with at least 1 postoperative imaging study were retrospectively reviewed.

Computed tomography for the diagnosis and management of abdominal aortic aneurysms.

Computed tomography (CT) is useful in the detection and diagnosis of abdominal aortic aneurysms (AAA). Rupture risk can be assessed by accurately measuring diameter, tortuosity, thrombus extent, and wall stress. CT can aid in accurately determining anatomic variants as well as AAA etiology.

Carotid-subclavian arterial reconstruction: concomitant ipsilateral carotid endarterectomy increases risk of perioperative stroke.

Background: Carotid-subclavian bypass (CSB) and carotid-subclavian transposition (CST) have excellent long-term patency with low perioperative mortality and morbidity. Carotid endarterectomy (CEA) is necessary for severe ipsilateral internal carotid artery stenosis in a small subset of these patients. CEA can be performed as a combined or separate procedure.
