Combined transarterial embolization and percutaneous image-guided ablation for the treatment of T1B and central renal tumors in patients with high surgical risk

Objectives: The objectives of the study were to assess technical success, efficacy, and complications combination transarterial embolization (TAE) followed by percutaneous ablation in treating stage cT1b central renal tumors. Material Methods: An institutional registry was reviewed for patients who underwent TAE computed tomography (CT)-guided from 2007 2018. Twenty-eight consecutive (median age 69 years; range 45–89 years) with tumor size ranging 25 58 mm (average 45 mm), including 24 T1b tumors four T1a tumors, identified. Nineteen had cryoablation (CA), nine radiofrequency (RFA). Technical local control, post-procedure retrospectively reviewed. Results: All procedures technically successful. Local control achieved 26 28 (92.9%) at a median follow-up months. recurrence found two patients, time 15 recurrences occurred one patient plus CA RFA. Self-limited hematoma hematuria minor observed 3 (10.7%). Only major complication. This developed ureteral obstruction perirenal abscess requiring stent drainage without long-term sequela. Conclusion: In this cohort CT-guided an effective, well-tolerated, safe treatment
