Abstract 15462: Gender-related Outcomes of Thoracic Endovascular Aortic Repair for Descending Thoracic Aortic Aneurysms
Objectives: To review and re-evaluate the poor outcome of thoracic endovascular repair in women at our institution.
Methods and Materials: We reviewed our data on thoracic endovascular aortic repair from 2006 to 2014 for descending thoracic aortic aneuryms only. Pre-operative comorbidities, size of aneurysm, endograft usage, postoperative complications and mortalities were compared. A 24-month follow-up data was plotted in Kaplan-Meier survival curve.
Results: There were 26 women and 21men, mean ages 81.7 ± 6.8 years and 72.8 ± 11.9 years (p < .004), respectively. Average aortic size was 6.2 cm and 4 (5.7%) ruptured aneurysms in women and 5.5 cm with only one noted rupture in men. Congestive heart failure as comorbidity showed a higher risk of death associated with TEVAR by logistic regression analysis. Less than 30 days mortality was 2 (7.7%) and > 30 days 6 (23%) in the women group. There were no early or late deaths in the men group (p < 0.0056). Deaths were only in women.
Kaplan-Meier curve showing comparative 24-month survival between gender. The 24-month overall survival was 100% for males and 23.3% for females. Lack of mortality events among males resulted in no hazard ratio and 95% confidence interval for HR for gender.
Conclusion: Congestive heart failure as comorbidity poses a greater risk of death postoperatively in TEVAR. Women undergoing TEVAR have greater mortality risk than men, because of larger size of the aneurysm and incidence of rupture during intervention.
