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.We recommend risk mitigation strategies for providers placing or caring for patients with regional nerve catheters.
