CLINICAL CHARACTERISTICS, IMAGING, AND SURGICAL OUTCOMES OF CHRONIC SUBDURAL HEMATOMA AT LONG KHANH REGIONAL GENERAL HOSPITAL FROM 2021 TO 2024

Abstract

Chronic subdural hematoma (CSDH), a prevalent condition in the elderly often triggered by trauma, demands prompt intervention to avert neurological decline. This retrospective study analyzed the clinical profiles, imaging features, and surgical outcomes of 34 CSDH patients treated with single-burr-hole drainage at Long Khanh Regional General Hospital from January 2021 to September 2024. Patients had a mean age of 68.4 ± 16.9 years, with a marked male predominance (88.2%); trauma was the primary etiology in 52.9% of cases. Predominant symptoms included motor weakness (64.7%), headache (55.8%), and altered consciousness (23.5%), with most (76.5%) presenting a Glasgow Coma Scale (GCS) score of 13–15. CT imaging showed mean hematoma thickness of 21.1 ± 6.3 mm and midline shift of 9.4 ± 4.8 mm, with 70.6% unilateral. All underwent single-burr-hole drainage, achieving postoperative GCS 15 in 88.2%. Recurrence occurred in 11.7% (n=4), with one reoperation; mortality was 2.9%, and mean hospital stay was 10.7 ± 5.4 days. At discharge, 73.5% exhibited good outcomes, with the same proportion resuming normal daily activities within one month, underscoring single-burr-hole drainage as a safe, effective option with high success, low complications, and strong functional recovery.
