Insucesso da Técnica Radial em Centro com Alto Volume de Procedimentos

Failure of the Transradial Approach in a High-Volume Center background: The mechanisms and predictors of failed transradial approach in centers dedicated to this technique are not well characterized and were the main objective of this analysis. methods: 6,808 consecutive patients undergoing transradial coronary procedures by operators with utilization rate greater than 90% were included. Simple and multiple logistic regression models were used to identify the predictors of failed transradial approach. Results: Transradial failure rate was 1.7%. Vascular complications were observed in 5%, with a prevalence of asymptomatic arterial occlusion and subcutaneous hematomas. Predictors of failure were female gender (OR = 1.87; 95% CI 1.29-2.71; p = 0.01), age > 70 years (OR = 1.78; 95% CI 1.06-2.98; p = 0.03) and presence of chronic peripheral arterial disease (OR = 5.71; 95% CI 2.40-13.54; p < 0.01). Conclusions: In a high-volume radial center, failure rate was < 2% and variables associated with technical failure were female gender, advanced age and peripheral arterial disease. DesCRIPToRs: Radial artery. Percutaneous coronary intervention. Hemorrhage. Ischemia.
