Background: There is a consensus, that transradial-access (TRA) for coronary procedures should be preferred over transfemoral-access (TFA). Previously, forearm-artery-angiography was mainly performed when difficulties during the advancement of the guidewire were encountered. We explored the implication of a standardized forearm-angiography (SFA) on procedural success rates of TRA.Methods: 1191 consecutive cases were assessed retrospectively. Primary TFA rates, crossover to TFA, reasons for forearm-artery-access (FAA) failure, the prevalence of kinking at the level of the forearm and the occurrence of vascular complications were analyzed.Results: Primary FAA access was attempted in 97.9%. Crossover to TFA after a primary or secondary FAA attempt was necessary in 2.8%. Severe kinking was the most frequent cause of FAA failure and occurred in 3.0%. A second or third FAA attempt to avoid TFA was successful in 81%. Severe kinking at the level of the forearm was reported in 1.8%.Conclusion:This is the first study to provide detailed success rates of a primary FAA strategy combined with SFA. While severe kinking proved to be a rare but relevant challenge for FAA success, the prevalence of arterial spasm was marginal. Multiple attempts of FAA to avoid TFA might be safe possibly due to collateral blood supply. |
