Routine Shunting During Carotid Endarterectomy in Patients With Acute Watershed Stroke

Vascular and Endovascular Surgery

Abstract

To evaluate the protective role of routine shunting in patients with acute watershed stroke (WS) undergoing carotid endarterectomy (CEA). A total of 138 patients with symptomatic carotid stenosis (SCS) who underwent CEA after acute ischemic stroke from March 2008 to March 2015 were included in this study. Transient ischemic attacks were excluded. These patients were divided into 2 groups according to the topographic pattern of the stroke on magnetic resonance imaging: group 1, territorial strokes (TS) caused by emboli of carotid origin, and group 2, WS caused by a hemodynamic mechanism related to an SCS. Primary end points were 30-day mortality and postoperative neurological morbidity. The insertion of a Pruitt carotid shunt was performed systematically. Ninety (65.2%) patients presented a TS of carotid origin and were included in group 1, and 48 (34.8%) of the 138 patients had a WS related to an SCS and were included in group 2. The median time between clinical onset of the cerebral ischemic event and surgery was 9 days (range: 0-89 days). Postoperative mortality was 0%. Seven (5.1%) patients had an aggravation of the neurological status during the postoperative period, of whom 2 presented a complete regression of the symptoms...Continue Reading
