[Chronic subdural hematoma. Surgical management in 100 patients]

Chronic subdural hematoma (CSH) represents one of the most frequent types of intracranial hemorrhage. A standard surgical procedure is not available for each individual condition, and treatment options are often different at each institution. Therefore, management of CSH may represent a real challenge in the decision-making process of choosing a burr hole drainage instead of a large craniotomy in certain cases with borderline features. Prognosis depends directly on the appropriate selection of the surgical procedure. In this study we included 100 patients with CSH in order to analyze surgical results. The majority of the hematomas had a frontoparietal location in both cerebral hemispheres. The procedure of choice was usually a burr hole drainage in most cases. We found incomplete drainage in 18% of cases, each of which underwent a new surgical procedure and pneumoencephalus in 11% of cases. Mortality was 2%, which was less than reported in previous studies.
