Retained Perineural Catheter: A Sentinel Case Report

We report the rare complication of a retained peripheral nerve block catheter (PNBC). A 45-year-old man with intractable postamputation phantom limb pain was treated with continuous infusions via femoral and sciatic peripheral nerve catheters. The catheters were removed by an emergency department physician 2 days after placement. Five months later, the patient presented with a discharging sinus from the sciatic nerve catheter site. Magnetic resonance imaging (MRI) was inconclusive. Surgical exploration showed 15 cm of retained peripheral nerve catheter, which was removed.
