Ruptured abdominal aortic aneurysms in a private hospital: a decade's experience (1980-1989)

Area of Science:

• Vascular Surgery
• Emergency Medicine
• Surgical Outcomes

Background:

• Ruptured abdominal aortic aneurysms (RAAAs) present a significant surgical challenge with high mortality rates, despite advances in elective repair techniques.
• The management of RAAAs necessitates understanding prognostic factors to guide treatment strategies and improve patient outcomes.

Purpose of the Study:

• To identify predictors of patient survival following surgical intervention for ruptured abdominal aortic aneurysms.
• To evaluate the impact of patient age, hemodynamic stability, and rupture location on mortality in RAAA cases.

Main Methods:

• Retrospective analysis of 208 patients treated for RAAAs between 1980 and 1989.
• Logistic regression analysis was employed to determine factors correlating with patient survival.
• Key variables analyzed included patient age, preoperative blood pressure, and the location of aneurysm rupture (intraperitoneal vs. retroperitoneal).

Main Results:

• The overall mortality rate for RAAAs in this cohort was 49.5%.
• Survival rates were significantly higher for patients younger than 70 years (65.7%) compared to those 70 years or older (37.4%).
• Hemodynamically stable patients (blood pressure > 90 mm Hg) had a survival rate of 88.9%, versus 40.9% for unstable patients (blood pressure < 90 mm Hg). Patients with rupture confined to the retroperitoneum had a survival rate of 79.6%, compared to 38.3% for those with free intraperitoneal rupture.

Conclusions:

• Age, preoperative hemodynamic stability, and the extent of aneurysm rupture are critical determinants of survival in patients with ruptured abdominal aortic aneurysms.
• Despite high mortality, aggressive surgical intervention remains the primary treatment option for RAAAs.
• Further research into optimizing surgical approaches for RAAAs is warranted to improve outcomes.
