Event Description

Venkataramana, n.K.Multiloculated hydrocephalus: evolution of treatments and outcome.Journal of pediatric neurosciences.2021.16 (232-239).Doi: 10.4103/jpn.Jpn_73_16.Multiloculated hydrocephalus has an overall dismal functional outcome; imaging, early diagnosis, and technological advancements have made new roads in its management.Thirty infants with multiloculated hydrocephalus were studied.Progressive enlargement of the head was the most common presentation in 77%; of these, 47% were treated for neonatal meningitis and septicemia and 20% had suffered birth trauma.The majority required a single ventriculoperitoneal shunt; nine of them required multiple shunts; and six were managed with endoscopic fenestration and endoscopic third ventriculostomy.On follow-up, shunt malfunction was the most common complication.Only 26% of the survivors could achieve normal, neuropsychological developments.The mortality in this series is 6.7%.Reported events: 9 patients needed an additional shunt seventeen of them required shunt revisions and repositioning of ventricular catheters.
