Background: Sex-based differences in outcomes for the treatment of carotid arterial disease remains a controversial topic. The main objective of this study was to determine if gender differences influence 30-day stroke and mortality rates after carotid endarterectomy (CEA) in a large series of patients.
Methods: This is a retrospective study of all patients undergoing endarterectomy performed by a single surgeon between January 1, 1993 and December 15, 2010. The analysis included data from 1,046 CEAs (683 men and 363 women).
Results: There were no differences found in 30-day stroke, death, or combined stroke and death rates between women and men. The 30-day stroke rate was 1.6% for women and 1.8% for men (P = 0.98), with no significant differences between asymptomatic patients (1.7% for women vs. 1.2% for men; P = 0.70) or symptomatic patients (1.6% for women vs. 2.1% for men; P = 0.74). The 30-day mortality rate was 0.8% for women and 0.9% for men (P = 0.85) with no significant differences between asymptomatic patients (0.8% for women vs. 1.2% for men; P = 0.77) and symptomatic patients (0.8% for women vs. 0.7% for men; P = 0.84). There was a similar low risk for the combined outcome of stroke and death (1.9% for women vs. 2.2% for men; P = 0.92), with no differences between asymptomatic patients (1.7% for women vs. 1.6% for men; P = 0.89) or symptomatic patients (2.1% for women vs. 2.5% for men; P = 0.84).
Conclusions: Female sex does not influence 30-day stroke and mortality rates after CEA, regardless of preoperative symptom status.
