Non-invasive removal of a misplaced and knotted guidewire during ultrasound-guided central venous catheter insertion in a hybrid operating room: a case report.

Department of Anesthesiology, Yokohama Municipal Citizen's Hospital, Yokohama, Japan.
Background: The standard of care for placement of a central venous catheter (CVC) includes a real-time ultrasound (US)-guided technique. We describe a rare case in which the guidewire penetrated the posterior wall of the vessel, forming a knot, which precluded simple removal. This occurred despite the procedure being performed under real-time US guidance.

Coronary catheter kinking is an uncommon but potentially catastrophic complication of cardiac catheterization. Although simple maneuvers can often result in resolution of a kink, tighter knots may not respond to such measures. We provide a systematic, stepwise approach to the prevention and treatment of catheter kinking.

On-demand bactericidal and self-adaptive antifouling hydrogels for self-healing and lubricant coatings of catheters.

Catheter-related infections are one of the most common nosocomial infections with increasing morbidity and mortality, and robust antibacterial or antifouling catheter coatings remain great challenges for long-term implantation. Herein, multifunctional hydrogel coatings were developed to provide persistent and self-adaptive antifouling and antibacterial effects with self-healing and lubricant capabilities. Polyvinyl alcohol (PVA) with β-cyclodextrin (β-CD) grafts (PVA-Cd) and 4-arm polyethylene glycol (PEG) with adamantane and quaternary ammonium compound (QAC) terminals (QA-PEG-Ad) were crosslinked through host-guest recognitions between adamantane and β-CD moieties to acquire PVEQ coatings.

Methods to remove retained peripheral nerve catheters range from non-invasive techniques to open surgical procedures. This study reviews two cases requiring surgical intervention for catheter remnant removal after catheter breakage and presents a systematic review describing the diagnosis and treatment of retained perineural catheters. While still very rare, our case report and systematic review demonstrate that retained nerve catheters can occur as the result of kinking or knotting, but also from catheter breakage.
