Article Synopsis
- The study evaluated the technical success and safety of the Silk Vista (SV) device for treating intracranial aneurysms across multiple institutions.
- It reviewed data from 57 procedures involving 60 aneurysms, showing high success rates in device opening (91%) and complete wall apposition (92%).
- The findings indicated that the SV device is both feasible and technically safe, with a low rate of complications and no reported mortality.
Background: Cranioplasty is a commonly performed neurosurgical procedure used to repair defects of the cranial vault. For large defects, 3D printing allows for the creation of patient-specific synthetic cranioplasties. Although these implants provide excellent cosmetic results for patients, costs are quite high.

CNS anaplastic large cell lymphoma (ALCL) is a rare condition. A majority (80%) of ALCLs harbour anaplastic lymphoma kinase 1 (ALK-1) mutation with only a minority testing negative for this mutation.

Its prevalence is questionable with few previously reported cases of incidental CAPNON, and likely underdiagnosis. We report a unique case of incidental multifocal CAPNON.

Methods: Here, we report two cases of CAPNON and present a systematic review of the literature on skull base CAPNONs, to compare CAPNONs with calcified meningiomas.
Introduction: The Circle of Willis (CoW) is the most effective collateral circulation to the brain during internal carotid artery (ICA) occlusion. Carotid stump pressure (CSP) is an established surrogate measure of the cerebral collateral circulation. This study aims to use hemodynamic and computed tomography angiography measurements to determine the strongest influences upon the dependent variable, CSP.

Objectives: To evaluate the mechanical properties of PVA-C under physiological conditions; to assess PVA-C's suitability as a key component in a tissue-mimicking artificial lumbar intervertebral disc; and to identify suitable formulations that mimic the nucleus pulposus and anulus fibrosus.
Summary Of Background Data: Current lumbar intervertebral disc prostheses provide suboptimal symptom relief and do not restore natural load-cushioning.
