External Ventricular Drain Misadministration Events: Systematic Literature Review and Report of a Case.

Background And Objectives: External ventricular drain (EVD) is a common neurosurgical procedure with potential complications, including catheter misplacement, infection, mechanical obstruction, and inadvertent catheter pull-out. A less discussed but critical complication is the misadministration of medications into EVD. This project aimed to review the literature on EVD misadministration and discuss preventative measures, emphasizing the new International Organization for Standardization (ISO) standard for neuraxial connectors.

Sheep Head Cadaveric Model for the Transmeatal Extensions of the Retrosigmoid Approach.

The transmeatal extension of the retrosigmoid approach is an important procedure used in the treatment of various pathologies affecting the posterior fossa, petroclival region, and jugular foramen. Mastering this technique requires a high level of manual skill, particularly in temporal bone drilling. The objective of this study was to describe an easily accessible and cost-effective model of the transmeatal extension of the retrosigmoid approach using cadaveric sheep heads.

Including the Hollow Viscera (Stomach or Bowel) within the Ice Ball during Cryoablation: A Review of Adverse Events.

Purpose: To evaluate the safety of including hollow viscus (stomach or bowel) in the ice ball during cryoablation.

Materials And Methods: Forty-three patients who underwent 50 cryoablations between January 1, 2012, and February 1, 2023, were retrospectively reviewed and compared with a control cohort of those who underwent cryoablation without hollow visceral involvement (n = 86). Adverse events (AEs) were stratified by the Society of Interventional Radiology (SIR) AE classification system, 2017.
