Contralateral Subdural Hematoma Following Surgical Evacuation of Acute Subdural Hematoma: Super-Early Intervention and Clinical Implications.

BACKGROUND: Contralateral acute subdural hematoma (ASDH) is an uncommon but devastating complication during craniotomy and hematoma evacuation. It can lead to extremely poor outcomes if not treated properly and promptly. CASE DESCRIPTION: We present a case of a 49-year-old male who suffered contralateral ASDH during surgical evacuation of ASDH on the left side. Before the operation, we noticed slight contralateral ASDH on preoperative cranial computed tomography and were aware of its enlargement during operation. Decompression with a burr-hole craniotomy promptly followed by a decompressive craniectomy was performed to prevent contralateral ASDH. Unfortunately, we found intraoperative brain swelling, which indicated the development of a contralateral hematoma. The patient was reoperated and eventually had a poor prognosis.
CONCLUSIONS: We highlight that super-early intervention of contralateral hematoma is important to improve the prognosis of these patients.
