[Recanalization of chronic total coronary occlusion via transradial access]

The aim of this study was to investigate whether using radial access for coronary chronic total occlusion recanalization is effective and safe.

We enrolled 308 patients with chronic total coronary occlusion in our prospective study, between 2016 and 2019, in two cardiovascular centers. We included all transradial chronic total coronary occlusion percutan coronary interventions performed and all transfemoral cases were excluded from the study. A successful procedure was defined as recanalization of the target artery to <50% stenosis with successful stenting. We have investigated the procedural success rate, major adverse cardiac and cerebral events ratio, vascular complication rate, and the procedure related factors.

During the 3-year period, we enrolled 272 cases with complex transradial chronic total occlusion percutan coronary intervention. The average age was 73 ± 9 years, and 74% were men. The procedural success was 83.4%, while the technical success was 64.7%. The 1-year rate of major adverse cardiac and cerebral events ratio was 15.6%. The rate vascular access complications was 2.57%. Procedural complications were observed in 4.78%. In 1.8% of cases, it was necessary to convert from transradial to transfemoral access during the procedure due to technical reasons. The rate of vascular access complications was 2.57%. The average contrast consumption was 178.1 ml (176-211), the average procedure time 52.3 min (51.3-66.2), the radiation 2140 mGy (2110-2998).

Transradial access for chronic total occlusion recanalization is safe and effective and it is also associated with acceptable amount of access site complication rate. Orv Hetil. 2026; 167(1): 16-22.
