Severe catheter kinking and entrapment during transradial coronary angiography: percutaneous retrieval using a sheathless guide catheter.

ABSTRACT

The transradial (TR) approach for coronary angiography and intervention is increasingly used worldwide because of several advantages such as reduced bleeding and vascular complications. During TR procedures, aggressive catheter manipulation in the setting of complex and tortuous arterial anatomy can lead to catheter kinking and entrapment. Several percutaneous retrieval techniques using either homolateral radial access or femoral access have been described previously. We demonstrate, for the first time, the use of a sheathless guide catheter as a rescue technique to successfully retrieve a severely kinked and entrapped diagnostic catheter during TR access. © 2014 Wiley Periodicals, Inc.
