The influence of gender on outcome after ruptured abdominal aortic aneurysm

Abstract

Background: The influence of gender on the management of coronary artery disease is well documented, but few reports exist regarding the influence of gender on the management of peripheral arterial disease. Objective: The purpose of this study was to examine the influence of gender on selection for and short-term and long-term outcomes of repair of ruptured abdominal aortic aneurysm (RAAA) in a regional vascular surgery unit. Methods: Analysis of the prospectively gathered Lothian Surgical Audit database identified 692 patients (542 male and 150 female) admitted with RAAA between January 1, 1983, and December 31, 1995. Case notes were reviewed for patients who were admitted but not operated on. Operative mortality was defined as death within the same hospital admission. Long-term survival data were obtained from the General Register Office (GRO1 records) through record linkage by the Information and Statistics Division of the National Health Service of Scotland. Results: A total of 542 men (78%; median age, 72 years; age range, 46-93 years) and 150 women (22%; median age, 74 years; age range, 55-93 years) were admitted with RAAA (P =.12; Mann-Whitney U test). There was no significant difference in perioperative mortality between men and women. Although women who were not operated on (median age, 81 years; age range, 68-93 years) were significantly (P =.005) older than men who were not operated on (median age, 77 years; age range, 54-93 years), for any given age group, women appeared less likely than men to be offered surgical repair. Long-term survival after successful repair was comparable for the genders. Conclusions: Gender has no influence on either short-term or long-term outcome for patients undergoing operative repair of RAAA. However, women are less likely to be selected for operation than their male counterparts. (J Vasc Surg 2000;32:258-62.)
