Background And Purpose:
Decompressive hemicraniectomy has been used to treat spontaneous intracerebral hemorrhage, but the benefit of evacuating the hematoma during the procedure is unclear. We aim to evaluate the utility of performing clot evacuation during hemicraniectomy for spontaneous intracerebral hemorrhage.
Methods:
Retrospective cohort of consecutive patients (2010-2019) treated with decompressive hemicraniectomy for a spontaneous supratentorial intracerebral hemorrhage at the University of Iowa. We compared hemicraniectomy alone to hemicraniectomy plus hematoma evacuation. We analyzed clinical features and hematoma characteristics. The outcomes at 6 months were dichotomized into unfavorable (Glasgow Outcome Scale score 1-3) and favorable (Glasgow Outcome Scale score 4-5).
Results:
Eighty-three patients underwent decompressive hemicraniectomy for spontaneous intracerebral hemorrhage, 52 with hematoma evacuation, and 31 without hematoma evacuation. There were no statistically significant differences in clinical and radiographic characteristics between the 2 groups. Evacuating the hematoma in addition to hemicraniectomy did not change the odds of favorable outcome at 6 months (P=0.806).
Conclusions:
In this retrospective study, the performance of hematoma evacuation during decompressive hemicraniectomy for spontaneous intracerebral hemorrhage may not change functional outcomes over performing the hemicraniectomy alone.
