ObjectiveThe aim of the present study was to investigate factors associated with the development of ventriculomegaly suggestive of hydrocephalus (VSOH) after decompressive craniectomy with hematoma evacuation for hemispheric hypertensive intracerebral hemorrhage.MethodsThis study focused on 21 patients who underwent decompressive craniectomy with hematoma evacuation for hemispheric hypertensive intracerebral hemorrhage. The patients' clinical and radiological findings were retrospectively reviewed.ResultsEleven patients were male and ten were female, with an age range from 22 to 75 years (mean, 56.6 years). The preoperative Glasgow Coma Scale score ranged from 3 to 13 (mean, 6.9). Hematoma volumes ranged from 33.4 to 98.1 ml (mean, 74.2 ml). Hematoma locations were the basal ganglia in 10 patients and the subcortex in 11 patients. The presence of intraventricular hemorrhage was significantly associated with the development of VSOH (P=0.023). The distance of the decompressive defect to the midline and the presence of meningitis showed a strong trend for association with VSOH (P=0.051, P=0.090, respectively).ConclusionCareful attention should be paid to the occurrence of VSOH after decompressive craniectomy with hematoma evacuation in intracerebral hemorrhage patients with intraventricular extension, meningitis, and/or a short distance of the decompressive defect to the midline.Copyright © 2012 Elsevier B.V.
