ECT and intracranial vascular masses.

In 1990, the APA Task Force on ECT cited no "absolute" contraindications to ECT but "Substantial Risk" to be associated with ECT for patients with space occupying or other cerebral lesions with increased intracranial pressure and with bleeding or otherwise unstable vascular aneurysm or malformation. These findings indicate that patients with intracranial vascular masses are at increased risk for serious morbidity and mortality. Several authors have reported performing ECT in patients with intracranial vascular masses without adverse events by monitoring blood pressure both with and without pharmacologic intervention. Given the relatively recent change in practice of considering ECT for patients with intracranial vascular masses and the few number of cases thus far reported, we present a review of the existing literature and two additional cases of ECT performed with good result and no adverse events. With the cases we have presented, the literature now contains eight cases of ECT performed in patients with intracranial vascular masses, none of which had adverse outcomes. While such numbers do not establish unequivocal safety in this population, and the individual ECT practitioner must continue to make a risk/benefit analysis on a case-by-case basis, this report adds to the growing literature on the safety and efficacy of ECT for such patients.
