[Ruptured abdominal aortic aneurysm]

Area of Science:

• Vascular Surgery
• Surgical Outcomes
• Medical Diagnostics

Background:

• Ruptured abdominal aortic aneurysm (AAA) has a high mortality rate, with significant deaths occurring pre-hospital and perioperatively.
• Patients with ruptured AAA can be categorized into intra-abdominal and retro-peritoneal rupture groups.
• Retro-peritoneal rupture presents unique challenges in management and outcomes.

Purpose of the Study:

• To conduct a retrospective analysis of treatment outcomes for patients with retro-peritoneal AAA rupture.
• To evaluate the impact of changes in diagnostic and treatment protocols on perioperative mortality.
• To identify strategies for improving survival rates in this critical patient group.

Main Methods:

• Retrospective analysis of 78 patients with retro-peritoneal AAA rupture treated between 1985 and 1996.
• Comparison of two treatment periods: immediate surgery versus pre-operative intensive care and CT scanning.
• Data collection included perioperative mortality rates and diagnostic procedures.

Main Results:

• The perioperative mortality rate in the first period (immediate surgery) was 74.7%.
• The perioperative mortality rate decreased to 42.2% in the second period (delayed surgery with intensive care and CT).
• Computerized tomography (CT) scanning facilitated appropriate surgical technique selection.

Conclusions:

• A 1-3 hour delay in surgical intervention for retro-peritoneal AAA rupture, coupled with intensive pre-operative management and CT imaging, can significantly decrease perioperative mortality.
• Optimized patient preparation and diagnostic imaging are crucial for improving outcomes in ruptured AAA.
• This strategy highlights the benefit of a staged approach in managing complex vascular emergencies.
