Abdominal aortic aneurysms: Rotorua 1972-1982.

Area of Science:

• Vascular Surgery
• Surgical Outcomes
• Aortic Aneurysm Research

Background:

• Abdominal aortic aneurysms (AAAs) pose significant surgical challenges.
• Historical data on AAA treatment outcomes are crucial for understanding evolving surgical practices.

Purpose of the Study:

• To analyze the surgical experience and outcomes of abdominal aortic aneurysms (AAAs) treated at Rotorua Hospital between 1972 and 1982.
• To evaluate the impact of emergency versus elective surgery on patient mortality.

Main Methods:

• Retrospective analysis of 16 abdominal aortic aneurysm (AAA) resections performed from 1972 to 1982.
• Categorization of cases into acute (leaking) and elective (non-leaking) operations.
• Assessment of preoperative shock status and peri-operative mortality.

Main Results:

• A total of 16 abdominal aortic aneurysms (AAAs) were resected.
• Thirteen cases were acute operations for leaking aneurysms; three were elective.
• Mortality was higher in acute cases, with 3 out of 4 patients in shock preoperatively dying. One death occurred peri-operatively among 9 unshocked acute cases.

Conclusions:

• Emergency repair of leaking abdominal aortic aneurysms (AAAs) carries a substantial mortality risk, particularly when patients present in shock.
• Elective AAA repair appears to offer a better survival outcome compared to emergency surgery.
• This historical data highlights the critical need for timely diagnosis and intervention in managing abdominal aortic aneurysms (AAAs).
