Objectives
Female gender has been shown to negatively affect the outcomes of surgical bypass for peripheral arterial disease (PAD). We examined gender-related disparities in outcomes of endovascular PAD procedures in a large population-based study.Methods
We used discharge data from California hospitals to identify patients who had PAD interventions during 2005 to 2009. Logistic regression was used for 12-month reintervention, and Cox proportional hazard regression was used for amputation-free survival comparisons.Results
A total of 25 635 patients had endovascular procedures (11 389 [44.4%] women). Women were more likely than men (34.5% vs 30.1%, P < .0001) to have critical limb ischemia (CLI). Twelve-month reintervention rate in women was similar to men. Amputation-free survival was better among women than men (hazard ratio 0.84, 95% confidence interval [CI] 0.76-0.93, P = .0006).Conclusion
Despite presenting more frequently with CLI, women had better amputation-free survival than men following endovascular procedures. Future research should determine whether findings favor one type of PAD treatment modality over another for women.Many UC-authored scholarly publications are freely available on this site because of the UC's open access policies.
