Ruptured abdominal aortic aneurysm. The Tacoma experience

Area of Science:

• Vascular Surgery
• Aortic Aneurysm Research
• Trauma Surgery

Background:

• Ruptured abdominal aortic aneurysms (rAAA) represent a significant surgical emergency with high mortality.
• Prompt diagnosis and intervention are critical, but outcomes remain challenging.

Purpose of the Study:

• To report the surgical experience and outcomes of patients with ruptured abdominal aortic aneurysms.
• To identify factors influencing survival in rAAA cases.

Main Methods:

• Retrospective review of 37 consecutive patients undergoing surgery for rAAA over a 5-year period.
• Analysis of pre-operative, intra-operative, and post-operative data, including shock status and prior aneurysm diagnosis.

Main Results:

• The overall survival rate was 38%.
• Development of shock before surgery was common and associated with a poor prognosis.
• Prior knowledge of the aneurysm negatively impacted survival, despite not affecting diagnostic or shock status.

Conclusions:

• Urgent surgical intervention is paramount for ruptured abdominal aortic aneurysms.
• Improving community awareness of aneurysm symptoms and the need for rapid treatment is essential.
• Minimizing delays and avoiding pre-operative shock are critical for enhancing patient survival.
