Noninvasive Measurement of Cerebrospinal Fluid Flow in Shunted Hydrocephalus: Protocol for Scanner Calibration and Multisite Data Collection

JMIR Research Protocols
BackgroundVentricular shunts divert cerebrospinal fluid (CSF) in patients with hydrocephalus, which can be lifesaving. Untreated shunt failure may lead to increased intracranial pressure and neurological injury.

Portacaval shunt established in six dogs using magnetic compression technique. [PDF]

PLoS ONE, 2013
BACKGROUND AND AIMS: Installing the transjugular intrahepatic portosystemic shunt for portal hypertension is relatively safe, but complications are still high. To explore a new method of portacaval shunt, the magnetic compression technique was introduced

White matter changes should not exclude patients with idiopathic normal pressure hydrocephalus from shunt surgery

Fluids and Barriers of the CNS, 2022
Introduction White matter changes (WMC) on brain imaging can be classified as deep white matter hyperintensities (DWMH) or periventricular hyperintensities (PVH) and are frequently seen in patients with idiopathic normal pressure hydrocephalus (iNPH ...
