Non-invasive removal of a misplaced and knotted guidewire during ultrasound-guided central venous catheter insertion in a hybrid operating room: a case report.
JA Clin Rep
December 2024
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.

Article Synopsis
- - The study investigates the average fluoroscopic time and radiation exposure during basivertebral nerve radiofrequency ablations (BVNRFA), a new treatment for chronic low back pain that utilizes fluoroscopy for precise probe placement.
- - A total of 55 patients were analyzed; the findings revealed an average fluoroscopic time of 152.5 seconds, with radiation exposure quantified as a cumulative dose of 70.3 mGy.
- - The results highlight that the average fluoroscopic time required for BVNRFA is approximately 2.5 minutes, contributing valuable data on radiation safety during this procedure.
Robotic-Assisted Direct Anterior Approach Total Hip Arthroplasty: A 6.5-Fold Reduction in Fluoroscopic Radiation Exposure.
J Arthroplasty
December 2024
Department of Orthopedic Surgery, Hospital for Special Surgery, New York, NY, USA. Electronic address:
Introduction: Direct anterior approach (DAA) for total hip arthroplasty (THA) is increasing in popularity. Fluoroscopy is commonly utilized during DAA THA to increase the accuracy of component placement. The objective of this study was to compare the mean fluoroscopy time and radiation dose for DAA THA when utilizing robotic-assistance (RA), computer-assisted navigation (CAN), or manual (M) technique.

Department of Radiology, University of Chicago School of Medicine, Chicago, Illinois.
Article Synopsis
- Percutaneous image-guided needle biopsies are a safe and minimally invasive procedure used to obtain tissue from bone lesions, with radiologists playing a crucial role in patient care and coordination with clinical teams for accurate diagnoses.
- The review emphasizes the importance of patient selection, imaging workup, and managing risks like bleeding and thrombosis before conducting biopsies, often performed under moderate sedation for patient comfort.
- While computed tomography is the primary method for guidance, advancements in powered drill technology are improving the safety and efficiency of sampling from tough bone lesions, along with discussions on special techniques for challenging anatomical regions.
Tricuspid Valve S-Curves and Chamber Views: Implications for Transcatheter Tricuspid and Pulmonary Valve Interventions, Part 2 of the S-Curves and Chamber Views Series.

Division of Cardiology, Department of Medicine, Glen Hospital, McGill University Health Center, Montreal, Quebec, Canada. Electronic address:
Despite the challenges associated with periprocedural imaging, transcatheter tricuspid valve interventions have shown important impact on outcomes. A comprehensive understanding of the anatomy of the right heart and surrounding structures is crucial. One way to optimize these interventions is by identifying the optimal fluoroscopic viewing angles along the S-curve of the tricuspid valve.
