Objective: From April 2006 to February 2011, a total of 6 patients with internal carotid artery (ICA) stenosis who presented with acute deterioration of consciousness as well as neurological symptoms underwent emergent carotid artery stenting (CAS).
Methods: Preoperative and postoperative (after 90 days) National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) scores and perioperative events (including any stroke, cardiac infarction, and hyperperfusion syndrome) were evaluated.
Results: All patients were male with a mean age of 70.2 years. In all 6 patients, preoperative mRS was 5. However, the mRS score decreased postoperatively to 0 in 2 patients (33%), 1 in 2 patients (33%), 2 in 1 patient (17%), and 3 in 1 patient (17%). Mean NIHSS score before emergency CAS and at 90 days were 25 and 4, respectively. No patient demonstrated any perioperative events, and all patients recovered from acute deterioration of consciousness postoperatively.
Conclusions: Emergent CAS is a useful treatment option for acute stroke progression resulting from severe ICA stenosis.
