Electroconvulsive Therapy in Elderly Patients With Cerebral Aneurysms: A Systematic Review With Clinical Recommendations.

Abstract

Electroconvulsive therapy (ECT) is commonly used in the elderly due to its proven efficacy and safety profile. However, presence of cardiovascular comorbidities such as cerebral aneurysms may complicate the course of treatment. Our knowledge about the possible risk factors and precautionary measures remains limited. We performed a systematic review of published case reports of elderly patients with cerebral aneurysms treated with ECT. A total of 11 cases were included for the review. One patient died because of subarachnoid hemorrhage (SAH) secondary to ictal hypertensive surge during treatment with ECT. Risk factors such as history of hypertension, age of the patient, extent of the ictal surge in blood pressure, efficacy of prophylactic treatment to control surge in blood pressure and characteristics of cerebral aneurysm each elevated the risk of complication in these cases. We reviewed safety measures based on the evidence from the current literature available. ECT is safe in elderly patients with cerebral aneurysms provided appropriate safety measures are employed. Screening for cerebral aneurysms in high risk patients, effective prevention and management of blood pressure elevation acutely during ECT is the best practice to avoid adverse outcomes.
