BACKGROUND: Severe carotid stenosis is typically treated with carotid endarterectomy (CEA), but there is debate about the safety of this procedure in patients with contralateral carotid occlusion (CCO). To compare 30-day outcomes after CEA in patients with severe carotid stenosis or without CCO.
METHODS: This retrospective, single-institution analysis included 434 patients who underwent CEA. All CEAs were performed under general anesthesia, and carotid shunts were used in 32 patients. Patients were categorized into 2 groups according to patency of the contralateral carotid artery: groups I (no CCO, n = 394) and II (with CCO, n = 40). Demographics, preoperative symptomatic status, and frequency of early (<30 days) symptomatic neurologic complications and death were compared.
RESULTS: Total mortality after CEA was 1.6% (n = 7), 7 and 0 in groups I and II, respectively (P = 0.39). Overall stroke rate was 3.5% (n = 15), 15 and 0 in groups I and II, respectively (P = 0.20). Rate of transient ischemic attacks was 1.4% (n = 6), 5 and 1 in groups I and II, respectively (P = 0.37). Symptomatic group I patients had a higher rate of stroke and/or death (6.7% vs. 0%) (P = 0.85). In asymptomatic patients, the stroke and/or death rate was higher in group II (3.4% vs. 8.3%, P < 0.05). In group II, the frequency of shunt placement was higher (3% vs. 53%, P = 0.001). At mean follow-ups of 75.4 ± 47.5 months (group I) and 72.7 ± 49.9 months (group II), 157 and 13 additional deaths had occurred in groups I and II, respectively (P = 0.21).
CONCLUSIONS: Patients with CCO who undergo CEA do not appear to be at increased risk for perioperative incidence of stroke and/or death, or any neurologic event.
