Clinical Experience of Infantile Posthemorrhagic Hydrocephalus Treated with Ventriculo-Peritoneal Shunt.

Objective: Infantile posthemorrhagic hydrocephalus (IPHH) is the most common cause of infantile acquired hydrocephalus. We present and discuss our experience of treatment of six IPHH patients treated by a ventriculo-peritoneal (VP) shunt.

Methods: Six preterm infants treated by a VP shunt due to germinal matrix hemorrhage and hydrocephalus were included in our study. External ventricular drainage (EVD) was performed in patients with symptomatic ventricular dilatation, and a VP shunt was placed in the case of no improvement of the ventricular index despite several rounds of EVD. Radiographic findings and surgical outcomes were analyzed retrospectively.

Results: Four patients were male and two were female. Mean gestational age was 25 weeks and mean weight at birth was 868.3 g. One patient had a Papile grade II (16.7%) hemorrhage, three had a grade III (50%) hemorrhage, and two had a grade IV (33.3%) hemorrhage. EVD complications (one case of ventriculitis and one case of a ventricular abscess) occurred in two patients. VP shunt complications occurred in two patients (33.3%). Three cases had an isolated 4th ventricle; two of these cases had a VP shunt placed whereas the other case had a VP shunt placed in addition to aqueductoplasty using a neuroendoscope. At the last follow-up, three of the six patients had severe neurodevelopmental delay, two had mild neurodevelopmental delay, and one had normal development status.

Conclusion: In our study, although it is difficult to present the significant result for management of IPHH, we think that varied efforts are required to treat IPHH patients.
