Incidence of Ventriculomegaly in Patients With Craniosynostosis

Abstract

Hydrocephalus is variously associated with syndromic craniosynostosis (CS), while it is randomly encountered in nonsyndromic CS. But actually, the ventriculomegaly in CS is less described. In this study, the authors aim to establish whether ventriculomegaly is common in patients with CS, in both syndromic and nonsyndromic. Retrospective measurements of Evans index (EI) were taken from thin-section computed tomography scans of 169 preoperative CS patients to assess cerebral ventricular volume. EI >0.3 indicates ventricular enlargement. A total of 169 CS patients who underwent computed tomography scan from February 2018 to December 2021 were retrospectively evaluated, including 114 males and 55 females. The average age at diagnosis was 16 months (range: 1-103 mo). Among them, 37 with syndromic CS, including 17 ventricular megaly patients, had an EI >0.3 (46.0%), and 4 of them had intracranial hypertension and needed ventriculoperitoneal shunt treatment before cranial vault remolding. One hundred and thirty-two had nonsyndromic CS (100 single-suture CS, 32 multisuture CS), and 26 of them had an EI of 0.3 or greater (19.7%). Ventrocular megaly is common among patients with CS. Early craniotomy may stabilize ventricular dilation.
