Abstract 14147: Vascular Complication of Distal Transradial Approach in Patients With Acute Myocardial Infarction

Abstract

Background: The distal transradial approach (dTRA) for coronary catheterisation is a newly introduced alternative to the conventional transradial approach. This study investigated the incidence of vascular complication of the dTRA in patients with acute myocardial infarction (AMI) who underwent primary percutaneous coronary intervention (PCI). Methods: Consecutive 131 patients with AMI who underwent primary PCI between April 2018 and October 2019 were investigated. The dTRA was used as the primary approach whenever feasible in this study period. The bleeding complication after dTRA and the patency of the radial artery were investigated. The patency of the radial artery was examined using Doppler ultrasound in follow-up period. Results: Among the 131 AMI patients, 116 patients (88.5%) underwent successful primary PCI using the dTRA. The patients included 83 men (71.6%), and the mean age was 70.4 ± 12.9 years. A 5- or 6-French sheath (conventional or slender) was used in the primary procedure. The average time to achieving hemostasis was 5.0 ± 4.1 hours; TIMI minor bleeding was observed in 2 patients (1.5%) and there were no TIMI major bleeding. Color Doppler sonography of the radial artery was performed in 94 patients with the mean follow-up period of 273 ± 183 days, and the incidence of radial artery occlusion (RAO) was 1.1% (n=1). Conclusions: The application of dTRA is considered to have low incidences of bleeding complication and radial artery occlusion in the patients with AMI.
