Cerebrospinal fluid drainage in posthemorrhagic ventricular dilatation and its effects on cerebral hemodynamics

Objective: Posthemorrhagic ventricular dilatation (PHVD) is an important complication of intraventricular hemorrhage in preterm neonates. The definitive treatment of PHVD is ventriculoperitoneal shunt application, but being over 2500 g is expected for the operation, and there is still debate on the choice and timing of temporizing interventions until shunt application. In this prospective study, we aimed to observe the effects of ventricular decompression via lumbar puncture or reservoir on cerebral hemodynamics, ventricular measurements, and head circumference. Material and Methods: A total of 19 cerebrospinal fluid drainage applications in 10 patients ≤34 weeks gestation with PHVD was included. Ventricular size and medial cerebral artery Doppler measurements in ultrasonography, cerebral tissue oxygenation using near infrared spectroscopy, and head circumference of the patients who required ventricular decompression were recorded 1 h before and 2 h after interventions. Results: Ventricular measurements significantly decreased after intervention. Ventricular dilatation (ventricular index right/left and anterior horn width left/right: p=0.001/ p=0.02 and p
