Abstract

Objective: The current neurosurgical treatment for intraventricular hemorrhage (IVH) of prematurity resulting in posthemorrhagic hydrocephalus (PHH) seeks to reduce intracranial pressure with temporary and then permanent CSF diversion. In contrast, neuroendoscopic lavage (NEL) directly addresses the intraventricular blood that is hypothesized to damage the ependyma and parenchyma, leading to ventricular dilation and hydrocephalus. The authors sought to determine the feasibility of NEL in PHH.

Methods: The records of patients with a diagnosis of grade III or IV IVH were reviewed between September 2022 and February 2024. The Papile grade was determined on cranial ultrasonography. Demographic information collected included gestational age, birth weight, weight at the time of surgical intervention, infection confirmed with CSF, and rehemorrhage. Standard local guidelines for temporary (CSF reservoir) and permanent (shunt or endoscopic third ventriculostomy [ETV]) CSF diversion were implemented. Warmed lactated Ringer's was utilized for NEL. The primary outcome was the need for permanent CSF diversion (shunt or ETV).

Results: Twenty consecutive patients with grade III or IV IVH complicated by PHH were identified. Twelve patients underwent CSF reservoir placement and NEL, 4 underwent CSF reservoir placement only, 1 underwent shunt placement only, and 3 did not require neurosurgical intervention. Of the 12 patients who underwent reservoir placement and NEL, 8 (67%) ultimately met criteria for permanent CSF diversion compared with 2 of 4 (50%) who underwent CSF reservoir placement only. The mean gestational age at birth, birth weights, and age/weight at time of temporary CSF diversion were similar across groups. The average time interval between temporary and permanent CSF diversion was longer in patients who underwent NEL (2.5 months for shunt and 6.5 months for ETV) compared with CSF reservoir placement only (1.1 months).

Conclusions: NEL is an innovative alternative for the treatment of PHH of prematurity. The authors established an endoscopic lavage program at their institution and herein report the first published account in the United States of the feasibility of NEL for PHH.
