Clinical Trial Summary

Up to 40% of Obsessive-Compulsive Disorder (OCD) patients do not respond to conventional treatments (medications or behavior therapy). For some of them, a neurosurgical treatment can be indicated. A previous study, employing bilateral double-shot ventral capsular/ventral striatal (VC/VS) Gamma capsulotomy (GVC) for OCD has shown that this radiosurgical technique is potentially efficacious and relatively safe. However, a few patients may develop complications associated to radionecrosis (eg., brain cysts) in a long-term follow-up, which are probably associated to lesion volumes. Another study, with the preliminary results of smaller VC/VS Gamma capsulotomy lesions has suggested that this procedure is safe and remains efficacious. Our aim is to investigate the efficacy and safety profiles of smaller, single-shot VC/VS Gamma capsulotomy for OCD. This study will support the development of a future double-blind, randomized clinical trial of single-shot VC/VS Gamma capsulotomy.
