Abstract

Randomized controlled trials have demonstrated the efficacy of decompressive craniectomy in substantially decreasing mortality and improving functional outcome in middle cerebral artery infarction. The role of intracranial pressure (ICP) monitoring following decompressive craniectomy for stroke has not been well studied. We present a retrospective review of our experience with postoperative ICP monitoring in 12 stroke patients who underwent decompressive craniectomy. All elevations of ICP above a 20 mmHg threshold were noted. ICP was recorded for 1417 hours during which 68 ICP elevations were seen. Nine out of 12 patients had events of raised ICP, including eight with more than three elevations. A total of 81 interventions were employed to treat elevated ICP; 71 were effective in reducing ICP below the 20 mmHg threshold. The most frequent intervention was cerebrospinal fluid drainage via an external ventricular drain, which was effective in 85.4% of cases. Eleven out of 12 patients survived (92%) and attained a median modified Rankin Scale score of 4 (interquartile range 4-5) at a mean 15 month follow-up. In our experience, elevated ICP may commonly occur following decompressive craniectomy for stroke. Monitoring ICP influenced postoperative management and standard measures for reducing ICP were usually effective in the current series.
