Distal transradial artery access for vascular access intervention.
2020
Background Vascular access intervention is a useful treatment method for maintaining arteriovenous fistula (AVF) in dialysis patients. The outflow vein is commonly used as the access site for vascular access intervention. In cases where it is difficult to puncture veins due to multiple lesions or poor AVF development, vascular access intervention is performed using the radial artery. However, it is difficult to perform a vascular access intervention with radial artery access to the AVF in the distal forearm. We reported the efficacy and safety of vascular access intervention with distal transradial artery access (dTRA). Case series We have been conducting vascular access intervention with dTRA access since January 2019. We evaluated complications and procedure time for 12 cases of vascular access intervention with dTRA access performed from January to December 2019.The success rate of the procedure was 100% and no puncture hemorrhagic complication was observed in 12 cases performed at our institution. No radial artery occlusion was observed in 12 cases. The average fluoroscopy time was 11.5 min and the average contrast volume was 41 ml. Conclusion dTRA for vascular access intervention has advantages over conventional radial artery access in terms of safety of the procedure and ease of hemostasis.
