Assessing CSF Flow Dynamics in Pediatric Hemorrhagic Hydrocephalus

The fCTOT cap will be placed on the infant's head . After the MRI, fiber optics will be connected to the cap while donned on the infant and measurements will commence. After initial CSF diversion, a 0.5 cc volume of ICG solution will injected into the subcutaneous reservoir and measurements will be conducted using the fCTOT for 30 minutes. The fCTOT cap will be removed and NIRF planar imaging will be conducted to detect ICG in the subarachnoid space (SAS), draining cervical lymph nodes, along the spinal canal, and in the abdomen, where liver signals are expected. The infant will be transported back to the ICU where CSF diversion will continue and daily, 30 minutes NIRF imaging sessions may be conducted to detect ventricular flow into the SAS and liver clearance. Daily NIRF imaging will be performed in the neonatal intensive care unit (NICU) for as long as 7 days or until the ICG has cleared from the body from liver and/or CSF diversion.
