Endovascular aneurysm repair (EVAR) has been widely utilized in the management of abdominal aortic aneurysms (AAA). Previous studies have shown women to have an increased mortality after elective AAA open repair. We sought to evaluate gender-related outcomes and complications in patients undergoing EVAR.
Patient cohort was obtained from the HCUP-Nationwide Inpatient Sample (NIS) database. ICD-9-CM procedure codes were used to identify all patients undergoing EVAR between 2011-2013. In-hospital all-cause mortality, total cost of hospitalization, length of stay and procedure-related complications were examined. To adjust for multiple confounders propensity score matched analysis was utilized.
Of 329,902 patients undergoing EVAR, 62,496 (18.9%) were female. Women were older (75.1 vs. 73.1, p<0.001), with higher incidence of hypertension, chronic kidney disease, heart failure, COPD, thyroid disorders, coagulation disorders and rates of ruptured AAA. In-hospital all-cause mortality, procedure-related complications, total cost and length of hospitalization were significantly higher in the female cohort. After propensity score-adjusted analysis, these differences remained statistically significant (Table).
Women undergoing EVAR have increased in-hospital all-cause mortality, procedure-related complications, total cost and length of hospitalization compared with men. These findings highlight the importance for female-specific peri-procedural management strategies.
