Description and analysis of the dynamic and morphological flow pattern of the main arteries of the wrist and hand in a healthy spanish population.

BACKGROUND AND AIM

The vascular anatomy of the hand has already been widely described macroscopically. However, there are very few papers that study the pattern of normality of in vivo vascularisation that describe and analyse the main arteries of the hand. The aim of this paper was to carry out a study to serve as a reference for the normal values of size and flow of the radial and ulnar artery at the level of the wrist, and the digital radial and ulnar arteries at the level of the fingers.

MATERIAL AND METHOD

A descriptive observational cross-sectional study on 200 hands in 100 healthy volunteers aged between 20-30years. Doppler-colour ultrasound was performed on the ulnar and radial arteries in the wrist, as well as on the radial and ulnar digital arteries in each finger. Once the measurements had been taken, a general comparative analysis was performed also taking laterality, dominance and gender into account.

RESULTS

It was observed that the radial artery is larger in size than the ulnar at wrist level, however, it was the ulnar artery that showed flow dominance at this level. At finger level, the arteries are greater in size and flow in the areas of the fingers more protected from injury (digital ulnar artery in the first three and radial artery in the fourth and fifth digits).
