Summary
A large renal artery aneurysm was treated using a novel balloon remodelling technique. This endovascular approach successfully prevented coil migration during embolization.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Nephrology
Background:
- Renal artery aneurysms can be challenging to treat, especially large-necked ones.
- Co-existing conditions like cerebral arterial angiodysplasia and hypertension complicate management.
- Endovascular embolization is a potential treatment but faces technical hurdles.
Observation:
- A patient presented with a large-necked right renal artery aneurysm.
- The aneurysm's anatomy posed difficulties for standard endovascular embolization.
- Cerebral arterial angiodysplasia and arterial hypertension were noted comorbidities.
Findings:
- A balloon remodelling technique was employed for aneurysm embolization.
- This technique effectively prevented the migration of embolic coils.
- Successful endovascular treatment was achieved despite the challenging aneurysm morphology.
Implications:
- The balloon remodelling technique offers a viable solution for large-necked renal artery aneurysms.
- This method enhances the safety and efficacy of endovascular embolization.
- It expands treatment options for complex renal vascular pathologies.
