Key result
Bilateral transulnar access enables safe, successful retrograde CTO PCI when radial arteries are small.
Why the study?
There is limited data on the efficacy and safety of the transulnar approach for CTO PCI.

The bilateral ulnar approach may be a feasible alternative access site for retrograde chronic total occlusion interventions.
The transradial approach for coronary diagnostic and therapeutic interventions is a well-established, safe, and effective technique that has shown a success rate comparable to that of the transfemoral approach for chronic total occlusion (CTO) with less access site complications. Recently, the transulnar approach was also found to be a safe and feasible alternative for diagnostic and percutaneous coronary intervention (PCI). There is limited data on the efficacy and safety of the transulnar approach for CTO PCI. Here, we report the case of a patient who underwent coronary intervention for CTO via the bilateral ulnar approach.

Hussein et al. (2010) conducted a case report in Chronic total occlusion (CTO) (n=1). Bilateral percutaneous ulnar artery approach was evaluated on Procedural success. The bilateral transulnar approach was successfully and safely used for retrograde percutaneous coronary intervention of a chronic total occlusion in a patient with small radial arteries.
