With the single-stick technique proving to be an effective addition to the venous line placement toolkit, what is stopping IRs from venturing beyond the traditional dual-incision approach? In this episode of the BackTable Podcast, pediatric interventional radiologist Dr. Kevin Wong of USA Health joins host Dr. Ally Baheti to review the single-stick technique for central venous access, a method widely utilized in pediatric practice.

More about this episode
Delving into the origins, technical nuances, and clinical advantages, the physicians explore how the single-stick technique can reduce the risk of infection and minimize interference with other lines and tubing to improve patient care. The discussion provides a detailed technical breakdown of the procedure, offering a masterclass on navigating the curves up the neck as well as the equipment selection and sizing necessary to facilitate the process. With the aid of visual slides and demonstrations, Dr. Wong steps us through the specifics of bending the access needle, maneuvering tools to adapt to anatomical configurations, and handling ultrasound movement to confirm and maintain a safe trajectory throughout the procedure. The conversation emphasizes the tactile “feel” and attention to forces acting on the wire that are required to appropriately position the catheter.
Recognizing the logistical constraints that make it challenging for attendings to regularly adopt alternative procedural techniques, this episode serves as an accessible primer for clinicians looking to broaden their options for venous access with this effective, patient-centric technique.
