Summary
Isolated iliac artery aneurysms have a high rupture rate, significantly exceeding that of abdominal aortic aneurysms. Treatment strategies should be individualized due to varied locations and rupture risks.
Area of Science:
- Vascular Surgery
- Aneurysm Research
Background:
- Isolated iliac artery aneurysms are uncommon but carry a high risk of rupture.
- Understanding their characteristics and outcomes is crucial for effective management.
Purpose of the Study:
- To analyze the clinical features, rupture frequency, and treatment outcomes of isolated iliac artery aneurysms.
- To compare the rupture rate with abdominal aortic aneurysms.
Main Methods:
- Retrospective review of 41 patients with isolated iliac artery aneurysms over 21 years.
- Analysis of patient demographics, aneurysm characteristics, rupture status, and treatment modalities.
Main Results:
- Mean patient age was 72 years, with a mean aneurysm diameter of 6.0 cm.
- Rupture occurred in 49% of patients, a significantly higher rate than abdominal aortic aneurysms (8%).
- 30-day mortality was 9.8%, primarily due to rupture; diverse surgical options were employed.
Conclusions:
- Isolated iliac artery aneurysms present a substantial rupture risk.
- Treatment requires careful consideration of aneurysm location and patient risk, with multiple surgical approaches available.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
