AbstractNumerous studies on hydrocephalus after decompressive craniectomy (DC) for severe traumatic brain injury have been reported, whereas there have been only two reports on DC for hemispheric cerebral infarction. Here, we present the clinical details of 23 patients who underwent DC for hemispheric cerebral infarction and the incidence of hydrocephalus following DC. Of the 23 patients, 13 were male and 10 were female, with an age range from 34 to 75 years (mean, 60.8 years). The areas of hemispheric infarctions were those of the middle cerebral arteries in 12 patients and of the internal carotid arteries in 11 patients. The mean preoperative GCS score was 6. Nineteen patients (82.6 %) underwent cranioplasty. Pre-cranioplasty hydrocephalus was observed in 11 (47.8 %) patients. Four patients who had precranioplasty hydrocephalus were transferred or died without cranioplasty, and post-cranioplasty hydrocephalus occurred in 7 (36.8 %). Only one patient underwent a shunt procedure after cranioplasty. We consider that the explanation for the discrepancies between our study and the previous studies might lie in the definition of hydrocephalus and the indications for shunting.
