BackgroundChronic subdural hematoma (cSDH) ranks among the most prevalent neurosurgical conditions, with burr-hole drainage typically yielding favorable prognoses. Nevertheless, perioperative complications may arise, with remote intraparenchymal hemorrhage and subarachnoid hemorrhage occurring infrequently, while acute subdural hematoma (aSDH) remains a relatively common complication post-cSDH removal. The standard treatment for aSDH, typically large craniotomy, substantially elevates surgical risk.Methods And ResultsPatients admitted over the course of 51 months (February 2022 to May 2024) to a single institution for treatment of cSDH were retrospectively evaluated, with three cases of postoperative aSDH in elderly patients with cSDH, examining potential causative factors and proposing pertinent strategies. Three elderly patients, admitted urgently due to exacerbating symptoms, underwent preoperative assessment followed by emergency parietal burr-hole drainage. Regrettably, all three patients developed aSDH postoperatively. Various treatment approaches were employed: two cases received thrombolysis with 50,000 units of urokinase, while one case required a large craniotomy. Despite the patients achieving satisfactory outcomes without significant neurological deficits, this study advocates thrombolytic therapy as a potentially superior option for aSDH following cSDH surgery.ConclusionUrokinase-mediated subdural thrombolysis enhances hematoma clearance rates, suggesting a shift toward minimally invasive treatments to mitigate greater trauma. However, the paucity of evidence necessitates extensive research to validate its safety and efficacy.Copyright © 2024 The Author(s). Published by Elsevier Inc. All rights reserved.
