Abstract 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.

Abstract Background The routine radial artery (RA) puncture may fail when anatomical variation of the RA is encountered. Superficial radial artery (SRA) is one of the anatomic variants of the RA, with the incidence of about 1 to 1.5%. Recently, distal transradial access (dTRA) has emerged as a novel approach for coronary catheterization (CC), but performing CC through dTRA in patient with SRA has never been reported. Case presentation A 57-year-old male was admitted to hospital due to intermittent chest pain for 4 days. He was diagnosed with unstable angina pectoris and planned to receive coronary angiography (CAG). Before the operation, the existence and course of SRA were confirmed by palpation and ultrasonography with color Doppler. We marked the puncture site under the guidance of ultrasonography and successfully performed CC through the dTRA during patient’s hospitalization. Conclusions As far as we know, this is the first report that presents a case of SRA and percutaneous coronary intervention (PCI) treatment in which was successfully performed through dTRA. It is safe and feasible to perform CC via dTRA in case of SRA, and dTRA seems to be the preferred access.
