Impact of radial‐to‐aorta vascular anatomical variants on risk of failure in trans‐radial coronary procedures

Abstract

Failure of trans-radial procedures is associated to anatomic variants located from the wrist to the aorta. The "operative" ABC classification of anatomic variants is useful not only to categorize these anatomic variants, but also to predict the risk of failure of trans-radial approach.

Benefit of routine preprocedural radial artery angiography in STEMI patients

“…This was a retrospective study including all consecutive TRA STEMI patients in our center during this period and considering our center as a highly experienced radial center with 99% of wrist angiographies, we had lower rate of TRA failure with 3% compared to other published studies [15][16][17][18].…”

“…The reported overall failure in transradial procedures is between 1% and 10% [15][16][17][18][19]. Prior studies have reported that arterial anomalies found from wrist to aorta influence the success of transradial access and are cause for access crossover from TRA to other access sites [15][16][17][18].…”

Aberrant Right Subclavian Artery (Arteria Lusoria) Challenging 4-French Homolateral Transradial Coronary Catheterisation in Adulthood

“…Besides, anatomical arterial anomalies of the radial course and brachiocephalic system may hinder catheterisation while aortic arch variants often force operators to abandon the radial approach [4,9].…”

A less‐invasive totally‐endovascular (LITE) technique for trans‐femoral transcatheter aortic valve replacement

“…18 Despite these promising reports, the use of "secondary" radial approach did not enter the routine practice of many centers. The need to deal with upper arm vascular anatomic variants 19 • adopting the ulnar artery when bilateral abnormal radial anatomy was known or suspected on the bases of previous procedures.…”
