Intravenous literature: Oh, J.S., Choi, B.G., Chun, H.J. and Lee, H.G. (2013) The Twisting Maneuver for Fluoroscopic-guided Removal of Nonpalpable Tunneled Central Venous Access Catheter Cuffs. Journal of Vascular and Interventional Radiology. 24(9), p.1333-5.
The present report describes an alternative technique for the detection of nonpalpable polyester cuffs during the removal of tunneled central venous catheters. By twisting the external segment of the tunneled catheter in obese patients or those with severe edema, fluoroscopy can easily confirm the estimated site of the hidden cuff.
