The Safety of Electroconvulsive Therapy in Patients With Implanted Deep Brain Stimulators: A Review of the Literature and Case Report.

Currently there is no consensus statement about the safety of electroconvulsive therapy in patients who have implanted electrodes for deep brain stimulation. We present a summary of the existing literature on this topic, consisting of 21 cases, and then report a case performed at the University of Maryland Medical Center. Notably, with appropriate safety precautions and careful patient selection, there were no adverse events reported in the literature that were related to the presence of the deep brain stimulation device in any of the cases. Based on our review of the literature and the case we present, we have found no evidence so far to indicate that electroconvulsive therapy in patients with an implanted deep brain stimulator is unsafe.

Electroconvulsive Therapy in a Patient With a Recent Subarachnoid Hemorrhage.

The safety of electroconvulsive therapy (ECT) is improving with advances in anesthesia and ECT technique. There are published case reports of successful treatment of depression in patients who were once considered at high medical risk. Recent cerebral hemorrhage is one of the conditions considered to significantly increase the risk of ECT treatment. Literature search did not indicate any case reports of ECT treatment in patients with recent subarachnoid hemorrhage. We report the successful ECT treatment of depression in an older man who had developed a subarachnoid hemorrhage after a suicide attempt by ingestion of antifreeze.
