Effects Of Providing Additional Lesions To Single-Shot Gamma Ventral Capsulotomy For Obsessive Compulsive Disorder

A subset of refractory obsessive-compulsive disorder (OCD) patients may respond to neurosurgical procedures, such as Gamma Ventral Capsulotomy (GVC). Although most studies have employed bilateral double-shot (ds) targets, one study found that single-shot (ss) lesions were also efficacious in a small sample. Our aim was to replicate these findings with ss lesions and later include additional dorsal shots, in case of low efficacy.
