De quoi parle-t-on:

Il s'agit donc de l'évaluation d'un accès veineux central pour cathétérisation.
Je laisserais la sigle et mettrais une brève description entre parenthès.

Abstract
Ultrasound technology has revolutionized the practice of safer vascular access, for both venous and arterial cannulation.
The ability to visualize underlying structures of the chest, neck, and upper/lower extremities provides for greater
success, speed, and safety with all vascular access procedures. Ultrasound not only yields superior procedural advantages
but also provides a platform to perform a thorough assessment of the vascular structures to evaluate vessel health,
viability, size, and patency, including the location of other important and best avoided anatomical structures—prior to
performing any procedures. Such assessment is best performed using a systematic and standardized approach, as the
Rapid Central Vein Assessment, described in this study.
