Deep-Learning-based Automated Identification of Ventriculoperitoneal-Shunt Valve Models from Skull X-rays.

Introduction: Ventriculoperitoneal shunts (VPS) are an essential part of the treatment of hydrocephalus, with numerous valve models available with different ways of indicating pressure levels. The model types often need to be identified on X‑rays to assess pressure levels using a matching template. Artificial intelligence (AI), in particular deep learning, is ideally suited to automate repetitive tasks such as identifying different VPS valve models.

Background And Objectives: The study aimed to investigate the potential pathogenesis and present an implant retention procedure for patients with titanium mesh exposure after cranioplasty.
Methods: The clinical data were obtained from 26 consecutive cases with titanium mesh exposure who underwent surgical treatment between 2018 and 2023. These patients' medical records, scalp photographs, operative notes, and outcomes were retrospectively analyzed.

Background: Disproportionately enlarged subarachnoid space hydrocephalus (DESH) is one of the neuroradiological characteristics of idiopathic normal pressure hydrocephalus (iNPH), which makes statistical analyses of brain images difficult. This study aimed to develop and validate methods of accurate brain segmentation and spatial normalisation in patients with DESH by using the Computational Anatomy Toolbox (CAT12).
Methods: Two hundred ninety-eight iNPH patients with DESH and 25 healthy controls (HCs) who underwent cranial MRI were enrolled in this study.

Background: Hydrocephalus, an accumulation of cerebrospinal fluid (CSF) in the ventricles of the brain, is often treated via a shunt system to divert the excess CSF to a different compartment; if left untreated, it can lead to serious complications and permanent brain damage. It is estimated that one in every 500 people are born with hydrocephalus. Despite more than 60 years of concerted efforts, shunts still have the highest failure rate of any neurological device requiring follow-up shunt revision surgeries and contributing to the $2 billion cost of hydrocephalus care in the US alone.

Article Synopsis
- Pediatric intracranial tumors at the skull base are rare, challenging to treat due to complex anatomy, and lack substantial clinical evidence, prompting a study on surgical approaches and outcomes.
- The study involved 12 children under 18 who underwent skull base surgery from 2017 to 2023, analyzing demographics, tumor details, surgical methods, and survival rates.
- Results indicated a predominance of female patients, varying tumor locations and types, with 58.3% achieving gross or near-total resection; however, 33.3% of patients died from tumor progression within an average of 15 months.
