There are many methods of exchanging occluded or clogged percutaneous catheters. Typically, catheter exchange is simply performed over a guidewire. When debris occluding the lumen is compact, chronic, or extensive, such exchanges are difficult. Because salvaging an obstructed catheter, without risking loss of access, is difficult, multiple techniques to preserve organ access have been developed. This chapter describes a technique whereby a peel-away sheath is advanced over the catheter to re-establish organ access and facilitate catheter exchange. The placement of a coaxial peel-away sheath is useful for exchanging occluded enteric catheters, biliary drains, abscess drains, nephrostomies, and even selected vascular catheters.
