Doppler ultrasonographic evaluation of radial and ulnar artery diameters and blood flow, before and after percutaneous coronary interventions.

Aim: Although the transforearm approach is considered a safe and effective option for percutaneous coronary intervention, the different characteristics of the radial and ulnar arteries deserve attention. This study aimed to evaluate radial (RA) and ulnar artery (UA) diameter and blood flow parameters changes after catheterization.

Material And Method: A total of 328 patients were enrolled.

The Ulnar Artery as a Favorable Primary or Alternative Access Site for Coronary Angiography and Interventions.

The transulnar approach (TUA) has been considered both as primary access and as a secondary access site after transradial access (TRA) failure for coronary invasive procedures. However, there is little evidence supporting the use of the TUA as the first approach to diagnostic coronary angiography (CAG) or interventions. Patients (n = 587) who underwent CAG and/or angioplasty (292 patients via TRA, 295 patients via TUA) were included.
