Summary
Iliac aneurysms are underdiagnosed and often present with urological symptoms or rupture. Ruptured iliac aneurysms have a higher mortality rate than abdominal aortic aneurysms.
Area of Science:
- Vascular Surgery
- Epidemiology
- Aneurysm Research
Background:
- Comparing epidemiology, risk factors, and manifestations of iliac and abdominal aortic aneurysms.
- Investigating the prevalence and clinical presentation of these vascular conditions.
Purpose of the Study:
- To compare the epidemiology, risk factors, and clinical manifestations of iliac aneurysms versus abdominal aortic aneurysms.
- To assess the diagnostic challenges and outcomes associated with iliac aneurysms.
Main Methods:
- Screening 5,470 men aged 65-73 for abdominal aortic aneurysms.
- Reviewing 350 patients operated on for central aneurysms (1989-1997).
Main Results:
- Abdominal aortic aneurysms detected in 4.0% of screened men; 0.56% required surgery.
- Iliac aneurysms had lower serum cholesterol levels, higher urological symptoms (42%), and higher rupture rates (58%) than abdominal aortic aneurysms.
- Perioperative mortality was significantly higher for ruptured iliac aneurysms (57%) compared to ruptured abdominal aortic aneurysms (31%).
Conclusions:
- Iliac aneurysms are likely underdiagnosed, often presenting with symptoms or rupture.
- Ruptured iliac aneurysms demonstrate greater lethality than ruptured abdominal aortic aneurysms.
