CTO: in Radial Access with Similar Results to Femoral

One of the characteristics of chronic total occlusion (CTO) is the use of two access routes: femoral and radial. The radial approach is safer, but it has not been thoroughly analyzed in this type of PCI.

La recanalización de las CTO mejora la calidad de vidaThe study looked at 3709 patients undergoing left main percutaneous coronary intervention (PCI) for CTO. Only 2157 patients were accessed via femoral approach (58.1%), 728 via radial approach (19.6%), and 824 via both femoral and radial approach (22.2%). The use of radial approach increased over time.

 

Mean age was 65, and most patients were men. Those undergoing radial access or femoral and radial access PCI were younger, had more acute coronary syndrome, and less risk factors, peripheral coronary heart disease, or prior revascularization procedures.

J-CTO score (Multicenter CTO Registry in Japan) was lower in radial access patients (2.1±1.4 vs. 2.6±1.3 vs. 2.5±1.3; p < 0.001).

 

Antegrade dissection re-entry was less used in radial access patients, while retrograde techniques were higher.

 

Technical and procedural success was similar for the three strategies.

As regards in-hospital complications, there were no differences in mortality or MACE, but there was a higher rate of bleeding in the femoral approach group.

 

Conclusion

The use of radial access is no the rise when it comes to PCI for CTO, seeing as it is associated with less major bleeding, compared with the use of the femoral approach alone.
