“…There are a few studies in the literature reporting radial artery diameter in the Turkish population, with mean radial artery diameter being reported as 2.3-2.8 mm. [9,10] This study's findings were similar: radial artery diameter was 2.62±0.45 mm.…”

“…Since RAO is usually a thrombotic event, which is often related to the presence of micro-dissections, it is tempting to speculate that the association with occlusion time reflects a higher propensity to arterial thrombosis associated with prolonged flow impairment. Furthermore, our finding that post-procedural access site pain was also a predictor of RAO is in line with previous evidence [ 36 ], suggesting that prolonged pain after sheath removal might reflect extensive structural damage, which could in turn be a triggering for both acute thrombosis or more pronounced adverse vascular remodeling, thus leading to an increased RAO rate.…”

Objectives: To test a novel diagnostic technique to assess radial artery perfusion after transradial catheterization. Background: Despite being mostly asymptomatic, radial artery occlusion (RAO) is not a benign complication, and its diagnosis is frequently missed because it requires time-consuming diagnostic testing. We developed a novel operator-independent diagnostic test to assess RAO after coronary procedures through a transradial access (TRA) by means of hand Laser Perfusion Imaging (LPI). Methods: One hundred patients were evaluated before and after TRA by means of the LPI. A radial perfusion index (RPI) was calculated as the ratio between the total perfusion measured during ulnar occlusion and total basal perfusion. Vascular Duplex scan (VDS) was used as the standard of reference to assess the artery patency. Results: LPI correctly identified RAO in 100% of cases. Post-procedural RPI was 0.89 ± 0.13 in patients with radial patency vs. 0.15 ± 0.04 in patients with RAO (p < 0.001). In line with these results, ROC analysis showed an excellent diagnostic performance of the LPI, that correctly identified all RAO cases (Area Under the Curve, AUC = 1.0; p < 0.001), with an optimal diagnostic cutoff at 0.2 RPI. Conclusions: LPI is a reliable diagnostic technique for RAO, offering the advantages of being quick and simple to perform.

“…Saito et al [36] revealed severe flow reduction in patients with an A/S ratio <1. Likewise, we have also found that an A/S ratio <1 is associated with a higher incidence of long-term RAO, recently [37]. In the present study, we did not give a cutoff value for A/S ratio below which anatomical and functional changes occur because a larger study population is required to give a cutoff value to reach a statistical significance and power.…”

“…Although A/S ratio is a known predictor of radial artery patency as indicated by several studies [27][28][29], a few studies have given a cutoff value for A/S ratio for anatomical radial artery changes following TRC [36,37]. Saito et al [36] revealed severe flow reduction in patients with an A/S ratio <1.…”

The present study aimed to evaluate the late-term changes in radial artery luminal diameter (RAD) and vasodilatation response following transradial catheterization (TRC). TRC-inducing trauma to radial artery intima may trigger chronic phase vascular changes and lead to anatomical and functional impairment. There is controversial data whether the impairment persists or repairs later. Fifty-six consecutive patients undergoing TRC were enrolled prospectively. Baseline RAD, flow-mediated dilatation (FMD) and nitroglycerin-mediated dilatation (NMD) of the radial artery at the access site were measured before TRC by high-resolution ultrasound. Six months later; RAD, FMD and NMD were measured again at the same access site. RAD at the sixth month was reduced compared with pre-procedural measurements (2.85 ± 0.44 versus 2.74 ± 0.42 mm, p = 0.0001).The average FMD decreased to 5.66 ± 5.87 %, which was significantly lower than the observed pre-procedural FMD (9.45 ± 5.01 %) 6 months after TRC (p = 0.0001). Likewise, the average NMD at the sixth month was reduced compared with pre-procedural NMD (9.52 ± 6.77 versus 6.64 ± 6.51 %, p = 0.018). Logistic regression analysis indicated that pre-procedural radial artery diameter to sheath size ratio was the independent predictor of NMD reduction (95 % confidence interval, β = -9.74, p = 0.024). TRC may lead to a significant luminal diameter reduction and impairment of vasodilatation response in the radial artery at late term.
