[Thermoablation therapy in the treatment of benign lesions].

INTRODUCTION
Depending on their size and location, some benign tumors can cause prolonged discomfort and even rupture and fatal bleeding in severe cases. Hitherto the therapeutic strategies for such lesions were observation, surgery and in selected cases transarterial embolization.


AIM
Our aim was to present the possibilities of thermoablation for treating lesions.


METHOD
Here we present interventions of four patients in Semmelweis University Department of Transplantation and Surgery. A thyroid adenoma and a kidney angiomyolipoma were treated with radiofrequency ablation. Two patients with a liver haemangioma were treated with microwave thermoablation technique.


RESULTS
Complications were not observed in any of the cases. In most cases, the size of the treated lesions decreased. The mean decrease in volume was 32.7%. The contrast enhancement of the lesions also decreased, the mean reduction in contrast enhancing volume was 75.3%.


CONCLUSIONS
Thermoablational procedures for the benign tumors presented above are safe. The therapy shows excellent cosmetic results, a shorter hospital stay and quicker recovery. Orv. Hetil., 2016, 157(51), 2040-2047.
