A simple, inexpensive technique for clearing obstructed closed suction drainage catheters.

Closed suction drains are frequently used after a variety of surgical procedures. Occlusion of these drains by thrombus or debris is a common postoperative event. A simple, inexpensive technique for clearing occluded drains with the readily available polyvinylpropylene catheter used for central venous cannulation is described herein. This method represents an inexpensive alternative to a Fogarty balloon tipped thrombectomy catheter for the same purpose. Prompt recognition and clearance of an obstructed drain is essential to minimize postoperative wound complications.
