Complications following intracranial pressure monitoring in children: a 6-year single-center experience

Abstract

OBJECTIVEIntracranial pressure (ICP) monitoring is an important tool in the neurosurgeon’s armamentarium and is used for a wide range of indications. There are many different ICP monitors available, of which fiber-optic intraparenchymal devices are very popular. Here, the authors document their experience performing ICP monitoring from 2005 to 2015 and specifically complication rates following insertion of the Microsensor ICP monitor.METHODSA retrospective case series review of all patients who underwent ICP monitoring over a 10-year period from 2005 to 2015 was performed.RESULTSThere were 385 separate operations with an overall complication rate of 8.3% (32 of 385 cases). Hardware failure occurred in 4.2% of cases, the CSF leakage rate was 3.6%, the postoperative hemorrhage rate was 0.5%, and there was 1 case of infection (0.3% of cases). Only patients with hardware problems required further surgery as a result of their complications, and no patient had any permanent morbidity or mortality from the procedure. Younger patients (p = 0.001) and patients with pathologically high ICP (13% of patients with high ICP vs 6.5% of patients with normal ICP; p = 0.04) were significantly more likely to have complications. There was no significant difference in the complication rates between general neurosurgical patients and craniofacial patients (7.6% vs 8.8%, respectively; p = 0.67).CONCLUSIONSIntraparenchymal ICP monitoring is a safe procedure associated with low complications and morbidity in the pediatric craniofacial and neurosurgical population and should be offered to appropriate patients to assess ICP with the reassurance of the safety record reported in this study.
