Abstract

OBJECTIVES We aimed to detect if pre-procedure vascular ultrasound scanning (VUS) of radial arteries (RAs) can increase the radial access success (RAS) rate and/or reduce the vascular access time (VAT), by guiding the choice of the proper access site for repeated trans-radial interventions (TRIs). BACKGROUND Currently, repeated-TRIs are encountered more frequently in most of the cath. labs. However, structural changes of the RAs after TRA may hinder it is usage for repeated-TRI. VUS is the most accurate noninvasive test for assessing RAs, nonetheless, its role in the setting of repeated-TRIs has not been studied before. MATERIAL AND METHODS We randomly assigned 300 patients undergoing repeated-TRI, to either planning the vascular access site based upon the result of VUS that was performed pre-procedural (group A, 150 patients) or to be left to the operator's discretion (group B, 150 patients). RESULTS In group A (143/145 [98.6%]), RAS rate was only numerically higher than group B (143/150 [95.3%]), P = 0.08. There was a statistically significant differences between both groups in VAT [(1.25 ± 0.17 min), vs. (4.95 ± 0.87 min) for group A and B, respectively, P = 0.02] and in procedure duration [(37.2 ± 19.8 min) vs. (51.8 ± 18.6 min) for group A and B, respectively, P = 0.04]. RA spasm was more common in group B [18% (27/150)] than group A [2% (3/145)], P = 0.001 CONCLUSION: VUS of RAs prior to repeated-TRI is associated with significant reduction in VAT, procedure duration, RA spasm and a mild increase in the RAS rate.
