Electroconvulsive therapy (ECT) was used to treat severe depressive illness
in two patients, one of whom had undergone recent neurosurgery for subdura
l hemorrhage (SDH) and another with a concurrent SDH in the absence of rais
ed intracranial pressure. Although the second patient died 1 month after th
e completion of ECT, in neither case did ECT extend the SDH or lead to othe
r intracranial complications. It would seem that ECT can be performed safel
y in the presence of SDH without mass effect or after surgical drainage of
SDH, although clinicians should proceed cautiously in close collaboration w
ith neurosurgical colleagues, review neuroimaging scans at regular interval
s during and after the course of ECT, and use the dose-titration method of
treatment with unilateral electrode placement away from the site of the les
ion or surgery to minimize adverse effects.
