Efficacy and Safety of Selective Arterial Embolization in the Management of Renal Angiomyolipoma
Main Article Content
Abstract
Objective : To evaluate the size reduction and complications associated with the selective arterial embolization (SAE) in the management of renal angiomyolipomas (AMLs).
Subjects and methods: We retrospectively reviewed 35 SAE procedures for AMLs performed between 2019 and 2024 at the University Medical Center of Ho Chi Minh City. Data included tumor characteristics, imaging before and after intervention, and clinical outcomes. Tumor size was measured using a combination of computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound (US). Primary outcomes included reduction in tumor volume and diameter, complications, re-embolization and changes in renal function.
Results: The median tumor diameter decreased from 6.0 cm to 5.0 cm, and median volume decreased from 55.8 mL to 34.2 mL, with a median volume reduction of 48.4%. Patients were followed for an average of 14.9 months. Three patients (8.6%) required re-embolization due to persistent symptoms or tumor growth. Post-embolization syndrome occurred in 14.3% of cases. One major complication was renal abscess (2.9%). No treatment-related mortality was observed. No significant change in serum creatinine was observed after SAE.
Conclusion: SAE is a safe and effective treatment modality for renal AMLs, resulting in significant tumor size reduction with a low incidence of major complications.
