Percutaneous drainage catheter placement is a frequently performed interventional radiology procedure. One of the common management complications of such catheters is obstruction or clogging of the catheter. Occluded drainage catheters are routinely exchanged over a guidewire under fluoroscopic guidance. At times, however, a guidewire cannot be passed through the catheter obstruction, and exchanging the catheter over a guidewire may become difficult or even impossible without losing access. Because salvaging an obstructed catheter, without risking loss of access, can be difficult, multiple techniques to preserve organ access have been developed. This chapter describes a technique whereby the creation of a new side hole in the catheter is used to re-establish wire access and facilitate catheter exchange. It is frequently useful for exchanging enteric tubes, urologic drainage catheters, biliary drainage catheters, and abscess drains.
