There is no consensus on the management of infantile chronic subdural collections. Subdural tapping, craniotomy and removal of membranes, and shunting from the subdural space have all been used. We performed continuous external subdural drainage (CESD) as a step prior to subdural-peritoneal shunt placement in the management of infantile chronic subdural fluid collections. A lumbar drainage set was used for CESD. The catheter was placed in the subdural space through the anterior fontanel with a Touhy needle. This percutaneous technique seems an easy and safe method for CESD in infants with chronic subdural collections.
