Case Reports
Entrapment of a kinked catheter in the radial artery during transradial coronary angiography.
The transradial approach is currently popular for vascular access during percutaneous coronary angiography and intervention. Catheter kinking during catheter manipulation is not uncommon, but mostly the kinked catheter can be unraveled by gentle rotation of catheter in the opposite direction. ⋯ We were able to catch the catheter tip with a 6 Fr Amplatz goose-neck snare kit (ev3, Inc.) guided by an 8 Fr guiding catheter via right femoral approach. We pulled the kinked catheter up into the brachial artery with large diameter where successful unraveling was possible, allowing for its successful removal through the radial sheath.
