Mechanics of a stuck central venous catheter removal

Although a surgical removal of tunneled central venous catheter is usually simple, it can become complicated when the catheter is found to be stuck because of its adherence within a central vein. If a catheter is pulled too hard, it may fracture within a central vein in two pieces. In this report, we describe the mechanics of central venous catheter breakage and provide a solution that minimizes the possibility of catheter from breaking as it is pulled out from its stuck position within a central vein.
