Superselective Renal Artery Embolization for Renal Angiomyolipoma
Sponsor: Botkin Hospital
Summary
To evaluate the efficacy and safety of selective endovascular embolization in the treatment of renal angiomyolipoma (AML). Materials and Methods: A prospective analysis will be conducted on patients who undergo transcatheter renal artery embolization for renal angiomyolipoma. Inclusion criteria will be radiologically confirmed angiomyolipoma based on CT and/or MRI findings and the presence of clinical indications for embolization. The primary outcomes will include the assessment of changes in serum creatinine and hemoglobin levels post-procedure, technical success rates, and the incidence of any complications. Expected Results: Data on patient demographics, tumor characteristics, and procedural outcomes will be collected and analyzed. Conclusion: This study aims to determine whether selective endovascular embolization is a safe and effective treatment modality for renal angiomyolipoma, with the expectation of demonstrating a high rate of technical success while preserving renal function.

Interventions
Selective endovascular embolization of kidney artery
Through arterial access (femoral, radial, or brachial), a catheter is advanced to the artery supplying the angiomyolipoma. Embolic agents used included Contour and Embosphere microspheres sized 50-710 μm. Blocking the blood vessels of the kidney that supply the tumor causes ischemia of the tumor, leading to stabilization of its growth and regression.Other Name
