Tips and tricks to manage twisted / kinked diagnostic angiography catheter – Tiger catheter (radial route)

Abstract Transradial approach for coronary intervention has gained popularity amongst experienced as well as upcoming interventional cardiologist. As compared to femoral access, the radial access has many advantages. Although like any other procedure, transradial approach is also not free of complications. Many vascular anomalies and complications are described, which includes radial artery spasm, tortuous course of axillary or subclavian artery, arteria lusoria, intimal dissection, perforation, compartment syndrome and rarely pseudoaneurysm formation. A few cases had been reported about kinking/twisting of radial catheter followed by trapping of catheter in the radial artery. Here we present such unusual case of an entrapped catheter in the radial artery and its successful retrieval with the help of goose snare. We would also like to propose a stepwise approach in such a case scenario.
