Abstract

Purpose

To identify prognostic factors in patients with primary chronic subdural hematoma (CSDH) undergoing wait-and-watch management.

Methods

A case–control study was conducted in a single center from February 2019 to November 2021 to identify independent influencing factors of wait-and-watch management in mild CSDH patients using wait-and-watch as monotherapy. A total of 39 patients who responded to wait-and-watch management (cases) and 24 nonresponders (controls) matched for age, sex, height, weight, MGS-GCS (Markwalder grading scale and Glasgow Coma Scale), and bilateral hematoma were included. Demographics, blood cell counts, serum biochemical levels, imaging data, and relevant clinical features at baseline were collected.

Results

Univariate analysis revealed significant differences between cases and controls in hematoma volume, ability to urinate, maximal thickness of the hematoma, and hypodensity of the hematoma. Hypodense hematoma and hematoma volume were independently associated with the outcome in multivariate analysis. Combining these independently influencing factors revealed an area under the receiver operator characteristic curve of 0.741 (95% CI 0.609–0.874, sensitivity = 0.783, specificity = 0.667).

Conclusions

The results of this study may aid in identifying patients with mild primary CSDH who could benefit from conservative management. While wait-and-watch management may be an option in some cases, clinicians need to suggest medical interventions, such as pharmacotherapy, when appropriate.
