OBJECT: The goal in this retrospective study was to examine the procedural complication rate for carotid angioplasty and stent placement performed without cerebral protection devices. METHODS: Between March 1996 and December 2003, 167 carotid angioplasty and/or stent placement procedures were performed without cerebral protection devices in 152 patients (57 women and 95 men whose mean age was 64 years, range 19-92 years). Seven of these patients underwent angioplasty alone. Eighty-nine patients presented with focal neurological symptoms. Indications for surgery included atherosclerosis, radiation-associated stenosis, dissection, pseudoaneurysm, and stretched endovascular coils from aneurysm treatment. In this study, the patients' medical records were reviewed for clinical characteristics, techniques used, and resulting intraprocedural and 30-day complication rates. The intraprocedural stroke rate was four (2.4%) of 167; this included three hemispheric strokes and one retinal embolus. All events occurred in patients who had symptomatic stenosis. The procedural transient ischemic complication rate was six (3.6%) of 167, as was the procedural nonneurological complication rate. During the 30 days postprocedure, one patient had died and three had suffered permanent ischemic events (two cerebral and one ocular). The composite 30-day postprocedural stroke and death rate was eight (5%) of 160. The rate of asymptomatic angiographically confirmed abnormalities was 0.6% (one treated vessel that was occluded but asymptomatic). The 30-day rate of nonneurological complications was 2.5%. A strong association between intraprocedural thromboembolic events (eight cases) and prior ischemic symptoms was found (p = 0.01). CONCLUSIONS: Carotid angioplasty and stent placement without cerebral protection devices is safe, particularly in patients without symptomatic stenosis. |
