Assessment the results of spontaneous supratentorial intracerebral hematoma aspiration under frameless navigation

Abstract

Objectives: To evaluate the results of spontaneous intracranial hematoma aspiration under frameless positioning and computed tomography. Methods: Retrospective study of 55 patients (patients) diagnosed with spontaneous intracranial hematoma (MTNS) by computed tomography (CT) scan from 05/2017 to 04/2022 at 108 Central Military Hospital.

Results: The mean volume fraction of residual hematoma was 26.24% after draining for an average of 2-3 days, respectively. There was no significant difference in the percentage of residual hematoma volume after draining. The favorable 1-month outcome with GOS 4 or 5 was significantly better in the group with a hematoma reduction of more than 60% compared with baseline hematoma volume (p=0.047), although no significant difference was observed. told at 6 months after aspiration. The factor that was significantly correlated with favorable outcome after aspiration 6 months was the ratio of final hematoma volume after drainage (p=0.016). Final hematoma volume ≤ 15 ml was correlated with favorable neurological outcomes at 1 and 6 months (p = 0.001 and 0.038).

Conclusion: There was no difference in the final residual hematoma volume and neurological outcome after 6 months depending on the time of aspiration aspiration of the hematoma. The factor influencing neurological outcome after 6 months of aspiration is the final hematoma volume remaining after drainage. Final hematoma volume ≤15ml was correlated with favorable neurological outcome at 1 and 6 months. This study provides the goal for hematoma aspiration technique to leave a residual hematoma volume ≤ 15ml.
