Balloon Angioplasty of the Radial Artery to Solve a Challenging Radial Sheath Insertion.

The inability to advance the dedicated wire of the transradial sheath in a radial artery with a good pulsatile blood flow is a very rare event. In this case, the advancement of a high-performance 0.014 inch coronary wire is the only option to gain the vessel. Then, if the transradial sheath is stuck in the proximal radial artery wall, balloon angioplasty of the radial artery may allow successful reinsertion of the transradial sheath. This technique allows the preservation of radial artery access, avoiding a shift to an alternative arterial approach.
