Abstract

BACKGROUND:

The initial surgical management of chronic subdural hematoma (CSDH) is still controversial, and a standard therapy does not exist. Because of the advanced age and multiple medical problems of the patients, surgical therapy is frequently associated with complications.

METHODS:

A retrospective study was performed on 172 patients with CSDH, comparing the efficacy of three different primary surgical methods: drainage of hematoma through two different burr-holes without membranectomy (Group A, n = 38); enlarged craniectomy with a size of about 30 mm craniotomy with partial membranectomy and drainage (Group B, n = 121); and extended craniotomy with partial membranectomy and drainage (Group C, n = 13).

RESULTS:

Independent of surgical method, the general outcome of the patients was good. The rate of reoperation in the group of burr-hole drainage was 16%, slightly lower than in partial membranectomy with enlarged craniectomy or extended craniotomy with 18% and 23%, respectively. In patients with coagulopathy, the rate of reoperation was 41% (16/43), significantly higher than the rate in noncoagulopathic patients 12% (15/129).

CONCLUSIONS:

In this study, an extended surgical approach with partial membranectomy has no advantages regarding the rate of reoperation and the outcome. As initial treatment, burr-hole drainage with irrigation of the hematoma cavity and closed-system drainage is recommended. Extended craniotomy with membranectomy is now reserved for instances of acute rebleeding with solid hematoma.
