{Abstract}: <B>OBJECTIVE: </B>Trans-radial access (TRA) is the recommended approach for coronary angiography and percutaneous coronary intervention (PCI). Radial artery occlusion (RAO) is the most common complication. We examined the incidence of RAO by means of duplex ultrasonography (DUSG) and the reverse Barbeau test (RBT), after TRA in a clinical setting using conventional pressure dressings to achieve haemostasis. All radial artery patency examinations were performed by one dedicated nurse after a brief training course, we assessed the feasibility and quality of this routine in regular clinical practice.<BR><B>RESULTS: </B>In total 97 patients undergoing first-time coronary angiograph and in some cases, PCI via TRA completed the study. Conventional pressure dressing as means of haemostasis was used. Radial artery patency was examined by DUSG and by RBT, before and at follow-up 1 month after the procedure. An inter- and intra-observer validation of the ultrasound measurements was performed before inclusion. Two cases of RAO (2.1%) were discovered following TRA. All RAO cases were detected by both DUSG and the RBT. Results from the inter-observer validation showed no statistically significant discrepancy between an experienced physician and a newly trained nurse operator (P = 0.403). An intraclass correlation coefficient (ICC) was calculated at 0.89 indicating excellent reproducibility.<BR><B>CONCLUSIONS: </B>In a high-volume TRA centre, we found a low incidence of RAO using conventional pressure dressing as means of haemostasis. The easy-to-use RBT detected all cases of RAO. Following a short course of training, a nurse from the cardiac catheterization laboratory was able to perform high quality DUSG examinations of the radial artery to assess patency.
