Abstract:
Distal transradial access(dTRA)was first applied in coronary heart disease intervention by Kiemeneij in 2017,dTRA has become an important technological advancement of coronary interventional therapy.This approach,performed by puncturing the distal radial artery within the anatomical snuffbox or Hegu point,significantly reduces the incidence of radial artery occlusion compared with conventional transradial access and shortens compression time to 2-3 hours after procedure.Clinical evidence confirms the efficacy of dTRA in facilitating complex percutaneous coronary interventions,including stenting of left main coronary artery bifurcation lesions and recanalization of chronic total occlusions.Its application has progressively expanded to neurointerventional procedures(cerebral angiography),tumor embolization(transarterial chemoembolization for hepatocellular carcinoma),and peripheral vascular interventions.Despite increasing clinical adoption,dTRA still faces challenges,including a long learning curve and relatively lower initial puncture success rates.Combined with the current paucity of robust evidence-based data,the viability of dTRA as a routine interventional access route remains a subject of debate.This article systematically reviews the anatomical landmarks,clinical advantages,limitations,and multidisciplinary applications of dTRA.This article aims to provide practical guidance for interventionalists and promote the standardization of this technique in daily clinical practice.
