Original Title: Upper extremity function post-transradial (TR)-PCI: interim results.
Presenter: Eva Zwaan.

The use of transradial access has increased in the clinical practice thanks to the reduction of vascular and bleeding complications in addition to the shorter time of hospitalization.

The aim of this study was to assess prevalence, magnitude and mechanisms responsible for the upper extremity dysfunction by transradial PCI (TR PCI). It was an observational, prospective, multicenter study with functional assessment of both upper extremities by Doppler to the radial artery, hand and forearm volumetric and palm pressure sensitivity assessment at 24 hrs., 2 weeks, 1 month and 6 months after procedure. Primary end point was positive dysfunction score validated by a surgeon.

74.9% of patients presented some dysfunction of the upper extremity at 2 weeks after procedure vs. the contralateral upper extremity.
The most frequent cause of dysfunction were sensitivity reduction, increase of arm volume and elbow strength reduction.
9.8% of patients presented radial artery occlusion.

Conclusion
According to this work, there is high prevalence of upper extremity dysfunction where transradial access was used 2 weeks after procedure. We should wait to complete follow up to determine whether there are more long-lasting complications.
