Letter to the Editor: Contralateral Subdural Effusion Secondary to Decompressive Craniectomy: Differences in Patients with Large Hemispheric Infarctions and Traumatic Brain Injury

We have read with great interest the recent article by Yang et al. The authors analyzed the data of 169 patients who underwent decompressive craniectomy after head trauma and found that 11 (6.5%) had contralateral subdural effusion. They also reported that clinical deterioration attributable to subdural effusion was seen in 8 of 11 cases. In 7 patients, effusion resolved spontaneously and 4 patients required surgery. They concluded that postoperative contralateral subdural effusion was not an uncom-mon complication.
