Evaluation of the therapeutic effect of CT-guided microinvasive aspiration and drainage on patients with intracerebral hemorrhage

Objective To investigate the risk factors associated with the postoperative mortality after CT-guided microinvasive aspiration and drainage therapy, and to evaluate the therapeutic effect of the therapy on patients with intracerebral hemorrhage.Methods The mortality of 87 patients with supratentorial spontaneous intracerebral hemorrhage was prospectively observed,who had received the CT-guided microinvasive aspiration and drainage therapy with the YL-1 puncture needle. The postoperative mortality and various factors were statistically analyzed respectively including age,hematoma location and volume, Glasgow coma scale (GCS) score,the shift of cerebral midline construct,operation time,the clearance rate of hematoma in the first time,blood pressure control,the residual hematoma volume postextubation and complications.Results The postoperative mortality of the CT-guided microinvasive aspiration and drainage therapy was correlated with the hematoma volume,GCS and the shift of cerebral midline construct (P0.05),but not with age,hematoma location,operation time,the clearance rate of hematoma in the first time,blood pressure control,the residual hematoma volume postextubation and complications (P0.05).The recurrent hemorrhage rate was higher than that of previous reports,which had nothing to do with the antihypertensive treatment (P0.05).Conclusion The hematoma volume,GCS and the shift of cerebral midline construct are the leading factors related with the therapeutic effect of CT-guided microinvasive aspiration and drainage,which play important roles in the guidance of the operation indications and in improving the prognosis of patients with intracerebral hemorrhage.
