Emergency surgery is an effective way to improve the outcome of severe spontaneous intracerebral hemorrhage patients on long-term oral antiplatelet therapy.

The necessity of emergency surgery for severe spontaneous intracerebral hemorrhage (SSICH) patients on long-term oral antiplatelet therapy (LOAPT) remains unclear. The aim of this study was to investigate the effect and safety of emergency surgery for SSICH patients on LOAPT (SSICH-LOAPT patients). In this study, a retrospective review of patients admitted to our institution for SSICH from January 2012 to December 2018 was conducted. The collected data included demographic, clinical, and surgical information. The outcome was recorded at 3 months after primary hemorrhage. The outcome of SSICH-LOAPT patients receiving emergency surgery and conservative treatment were compared. The risk of postoperative intracranial bleeding (PIB) in operated SSICH-LOAPT patients was further investigated. A total of 522 SSICH patients were retrospectively reviewed, including 181 SSICH-LOAPT patients and 269 operated patients. The total mortality and in-hospital mortality were 40.6% and 19.3%, respectively. As compared with SSICH-LOAPT patients receiving conservative treatment, the operated SSICH-LOAPT patients showed a lower total (p = 0.043) and in-hospital mortality (p = 0.024). When compared with operated patients not on LOAPT, the operated patients on LOAPT exhibited a higher rate of PIB (OR, 2.34; 95% CI 1.14-4.79; p = 0.018). As demonstrated by the multivariate logistic analysis, dual antiplatelet therapy were independent risk factors associated with PIB in operated SSICH-LOAPT patients (OR, 3.42; CI, 1.01-11.51; p = 0.047). Despite of increasing risk of PIB, emergency surgery could improve the outcome of SSICH-LOAPT patients as it could be effective in reducing mortality. Dual antiplatelet therapy was the independent risk factor related to the PIB in operated SSICH-LOAPT patients.
