Can striatal dopamine transporter uptake increase following CSF tap test in patients with idiopathic normal pressure hydrocephalus?
Reduced striatal dopamine transporter (DAT) uptake is not uncommon in patients with normal pressure hydrocephalus (NPH) [1]. Furthermore, recent reports have shown that striatal dopaminergic deficit on DAT scans can improve after a shunt operation [2,3]. In this preliminary study, we investigated whether reduced striatal 18F –N-(3-fluoropropyl)-2β-carboxymethoxy-3β-(4-iodophenyl) nortropane (18F-FP-CIT) uptake can also improve after a cerebrospinal fluid (CSF) tap test (TT) in idiopathic NPH (iNPH) patients by calculating the specific binding ratio (SBR) of the striatum [3].

Applied deep learning in neurosurgery: identifying cerebrospinal fluid (CSF) shunt systems in hydrocephalus patients
ConclusionThis technology has the potential to automatically detect different shunt valve models in a fast and precise way and may facilitate the identification of an unknown shunt valve on X-ray or CT scout images. The deep learning model we developed could be integrated into PACS systems or standalone mobile applications to enhance clinical workflows. (Source: Acta Neurochirurgica)

Absence of hernia sack in patients undergoing prenatal repair of spina bifida increases the risk of developing shunt-dependent hydrocephalus
Spina bifida aperta (SBA), with (myelomeningocele) or without (myeloschisis) a hernia sack, is the most common congenital defect of the central nervous system. Prenatal surgical closure of SBA lowers the risk for developing shunt-dependent hydrocephalus, offering a chance at better motor, urinary and gastrointestinal function. A total of 96 patients undergoing open fetal surgery for SBA were analyzed. The patients were subdivided into Group I – 12 (12.5%) – without a hernia sack (myeloschisis) and Group II – 84 (87.5%) – with a hernia sack (myelomeningocele).

Intraventricular Shunt Catheter Placement of Adult Normal Pressure Hydrocephalus Using an AxiEMTM Electromagnetic Neuronavigation System: A Single-Center Experience
