Shunt revision requirements after posthemorrhagic hydrocephalus of prematurity: insight into the time course of shunt dependency

摘要: Intraventricular hemorrhage (IVH) is a common affliction of preterm infants and often results in posthemorrhagic hydrocephalus (PHH). These patients typically eventually require permanent CSF diversion are presumed to be indefinitely shunt-dependent. To date, however, there has been no study long-term shunt revision requirements with PHH. We analyzed retrospectively collected data for 89 diagnosed grades III IV IVH PHH at our institution from 1998 2011. Sixty-nine out (77.5 %) underwent ventriculoperitoneal (VP) placement, 33 (47.8 %) required least one 18 (26.1 %) multiple revisions. The mean ± standard deviation follow-up time shunted was 5.0 ± 3.3 years. majority early failures were due proximal catheter malfunction, while later mostly distal problems. There significant difference the number requiring revisions first 3 years following initial VP insertion compared after 3 years, 28 versus 10 (p < 0.004). In 8 who evidence obstructive found on imaging either form an isolated fourth ventricular cyst or aqueductal stenosis. Our suggest that distinct subset PHH, may develop, resulting dependence diversion. Further factors associated within group warranted.
