Summary
Selective coil embolization is a feasible first-line treatment for saccular renal artery aneurysms. This minimally invasive endovascular therapy successfully treated a patient, preserving maximum kidney function.
Area of Science:
- Endovascular Surgery
- Interventional Radiology
- Nephrology
Background:
- Renal artery aneurysms (RAAs) are rare vascular lesions.
- Treatment options for RAAs have evolved, with a shift towards minimally invasive approaches.
- Saccular RAAs present unique management challenges.
Observation:
- A 52-year-old woman presented with hematuria, the sole symptom.
- Contrast-enhanced computerized tomography and angiography revealed a saccular aneurysm at the right main renal artery bifurcation.
- The aneurysm was approached using minimally invasive supraselective embolization.
Findings:
- The endovascular procedure was technically successful, with no intraoperative or postoperative complications.
- Follow-up angiography at 4 weeks confirmed the absence of endoleak or aneurysm recurrence.
- The minimally invasive technique preserved maximum functioning kidney tissue.
Implications:
- Selective coil embolization is a safe and effective first-line treatment for saccular renal artery aneurysms.
- Endovascular therapy offers a less invasive alternative to open surgery for RAAs.
- This approach maximizes renal function preservation, crucial for long-term patient outcomes.
