Since its introduction by Campeau in 1989, the transradial approach for coronary angiography has gained significant popularity among interventional cardiologists due to its lower access site complication rates, cost-effectiveness, and shorter hospital course. Although the transradial approach is much safer than the transfemoral approach, it has its own inherent rare complications including radial artery occlusion, thrombosis, nonocclusive radial artery injury, vasospasm, and compartment syndrome. Herein, we present an unusual case of entrapment and kinking of a catheter in the radial artery, which was successfully removed by using a gooseneck snare via the transfemoral route. The distal and proximal tips were then simultaneously rotated in opposite directions, allowing for the unkinking and removal of the catheter. To our knowledge, this is the first report of this rare complication.
