Summary
Endoleaks are common after endovascular aneurysm repair (EVAR). This review focuses on type II endoleaks, discussing indications, approaches, and techniques for endovascular treatment.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Endovascular Therapies
Background:
- Endovascular aneurysm repair (EVAR) is preferred for abdominal aortic aneurysms.
- Endoleaks, or continued blood flow into the aneurysm sac, are frequent complications.
- Type II endoleaks, from lumbar or mesenteric arteries, are the most common type.
Purpose of the Study:
- To review indications for endovascular treatment of type II endoleaks.
- To discuss the selection of appropriate endovascular approaches.
- To outline technical considerations for managing type II endoleaks.
Main Methods:
- Review of endovascular treatment options for type II endoleaks.
- Discussion of transarterial, transcaval, translumbar, and transabdominal approaches.
- Analysis of patient selection and procedural techniques.
Main Results:
- Type II endoleaks are the most common endoleak type.
- Various endovascular approaches exist for type II endoleak treatment.
- Careful selection of approach and technique is crucial for successful outcomes.
Conclusions:
- Endovascular treatment is a viable option for type II endoleaks.
- The choice of approach depends on anatomical and technical factors.
- This review provides guidance on managing type II endoleaks effectively.
