Lin s, wang l, shu y, et al.Rescue procedure for isolated dystonia after the secondary failure of globus pallidus internus deep brain stimulation.Frontiers in neuroscience.2022;16:924617.10.3389/fnins.2022.924617. globus pallidus internus (gpi) deep brain stimulation (dbs) is widely used in patients with dystonia.However, 10¿20% of patients receive insufficient benefits.The objectives of this study are to evaluate the effectiveness of bilateral subthalamic nucleus (stn) dbs along with unilateral posteroventral pallidotomy (pvp) in patients with dystonia who experienced unsatisfactory gpi-dbs and to address the reported rescue procedures after suboptimal dbs or lesion surgery in dystonia patients.Six patients with isolated dystonia who had previously undergone bilateral gpi-dbs with suboptimal improvement were included.Reported events: pli 10: one patient experienced cranial and cervical dystonia, along with dysarthria and dysphagia, requiring rescue surgery. pli 20: one patient experienced involuntary blinking and worsening cervical dystonia requiring rescue surgery.Pli 30: one patient experienced left torticollis, neck pain and cervical stiffness requiring rescue surgery.Pli 40: one patient experienced a new symptom of shoulder stiffness requiring rescue surgery.Pli 50: one patient experienced blepharospasms, mouth movement and low speaking tone requiring rescue surgery.Pli 60: one patient experienced severe involuntary movement in arms, shoulders, neck and mouth requiring rescue surgery.It was not possible to ascertain specific device information from the article or to match the reported event with any previously reported event.
