To explore the treatment of subdural effusion after decomperssive craniectomy.

The data of 20 cases with subdural effusion after decomperssive craniectomy in Neurosurgery Department of the First People’s Hospital of Shuangliu District from January 2017 to December 2019 were analyzed retrospectively. After the peak period of brain edema, external fixation of elastic cap, puncture and suction of Omaya capsule implantation, plastic titanium mesh repair and hyperbaric oxygen therapy were performed. The amount of subdural effusion, symptoms of neurological dysfunction, and modified Rankin scale were observed.

Among the 20 patients in this group, 6 cases had bilateral frontal temporal subdural effusion, 2 cases had effusion in the falx cerebri pool next to longitudinal crack, 12 cases had ipsilateral frontal temporal subdural effusion, of which 2 cases had ipsilateral progress subdural effusion, and Omaya capsule suction was placed; 20 patients were given elastic cap external fixation bandage, and all patients underwent plastic titanium mesh repair and hyperbaric oxygen treatment (3 courses, 30 times). All patients were followed up for 6 months after operation, and CT reexamination showed no recurrence of subdural effusion.

Decompressive craniectomy accompanied by subdural effusion, the good effect can be achieved by applying external fixation bandage of elastic cap, suction, early cranial repair and hyperbaric oxygen treatment.
