Summary
Isolated internal iliac artery aneurysms (IIAAs) are rare but dangerous, often presenting late and large with a high rupture risk and mortality. Early, aggressive management is crucial to prevent severe outcomes.
Area of Science:
- Vascular Surgery
- Aneurysm Disease
- Pelvic Anatomy
Background:
- Isolated internal iliac artery aneurysms (IIAAs) are a rare variant of aorto-iliac aneurysms, occurring in approximately 0.04% of cases.
- Their deep pelvic location often leads to late presentation with large aneurysm size.
- IIAAs have a high incidence of rupture (up to 38%) and associated mortality (58%).
Purpose of the Study:
- To review the current literature on isolated internal iliac artery aneurysms (IIAAs).
- To outline contemporary surgical and endovascular management strategies for IIAAs.
- To emphasize the necessity of early and aggressive treatment for IIAAs due to high rupture risks.
Main Methods:
- Literature review of isolated internal iliac artery aneurysms (IIAAs).
- Analysis of current surgical interventions for IIAAs.
- Evaluation of endovascular treatment options for IIAAs.
Main Results:
- IIAAs are rare, technically challenging aneurysms.
- High rates of rupture and mortality are associated with IIAAs.
- Management requires careful consideration of both surgical and endovascular approaches.
Conclusions:
- Early and aggressive management of IIAAs is mandatory.
- Surgical and endovascular options exist for treating these rare aneurysms.
- Prompt intervention is key to reducing morbidity and mortality from IIAA rupture.
