Suture Catheter for Rescue Perineural Catheter Placement When Unable to Position a Conventional Through-the-Needle Catheter: A Case Report.

The main purported benefit of suture-style catheters is the ability to secure the catheter at 2 sites, thereby decreasing the likelihood of catheter dislodgement. An additional benefit is the ability to precisely control the placement of the orifice to infuse local anesthetic. Here we present the case of a patient undergoing open ankle surgery for whom placement of a conventional through-the-needle popliteal sciatic perineural catheter for postoperative analgesia was attempted. Despite multiple attempts, the catheter repeatedly advanced beyond the nerve. Placement of a suture catheter was then attempted, and the catheter was successfully placed on the first attempt.
