Abstract

A comparative study chiefly of the recurrence rate of chronic subdural haematoma after two treatment modalities was conducted. Patients were divided into a burr hole strict closed-system drainage group (SCD group; n=56) and a burr hole closed-system drainage with irrigation group (CDI group; n=45). The burr hole strict closed-system drainage involved simply inserting a drainage tube into the haematoma cavity as quickly as possible after minimally incising the haematoma capsule. The introduction of air into the haematoma cavity was prevented, and irrigation was not performed. Symptoms in both groups disappeared soon after surgery, with no postoperative complications. Haematoma recurred in one patient (1.8%) of the SCD group compared with 5 (11.1%) of the CDI group. The rate of recurrence was significantly lower for the SCD than for the CDI group (p<0.05). In 4 of 5 recurrences in the CDI group, the volume of residual intracapsular air was sufficient after initial surgery. These results suggested that postoperative residual intracapsular air is a factor contributing to recurrence. Burr hole strict closed-system drainage is a simple, less invasive procedure with which to treat chronic subdural haematoma and the outcome is excellent. Furthermore, prevention of intracapsular air intrusion during surgery might help prevent recurrence.
