Risk Factors for Mortality and Recurrent Hemorrhage After Micro-invasive Evacuation in Patients With Intracranial Hematoma

Objective:To investigate the factors influencing effects of micro-invasive evacuation in treatment of patients with intracerebral hemorrhage.Methods:Clinical data of 261 cases with supratentorial spontaneous intracerebral hemorrhage treated by micro-invasive evacuation were analyzed retrospectively.Results:The mortality correlated with hematoma volume (P=0.0067), GCS (P0.0001), age (P=0.0255) and the residual hematoma volume postextubation (P=0.0406), but was not correlated with site of hematoma,opportunity of operation time, blood pressure on admission,complications and the shift of midline structure(P0.05). The rate of recurrent hemorrhage was higher in CAA patients (P=0.0334) and in patients untreated with hemostatics (P=0.0125),it was not correlated with antihypertensive treatment (P=0.3343).Conclusion:Risk factors of micro-invasive evacuation in intracerebral hemorrhagic patients mainly affected by hematoma volume,GCS,age and the residual hematoma volume postextubation.The rate of recurrent hemorrhage is higher in CAA patients,but not correlates with antihypertensive treatment.
