Abstract
Background
This study thoroughly analyzes the anatomic variations of the brachioradial artery (radial artery of high origin) based on the variability of its origin, the presence and types of anastomosis with the brachial artery in the cubital fossa (“cubital crossover” or “cubital connection”), and the pattern of radial recurrent arteries, as well as the vascular territory within the hand.
Material and Methods
One hundred and twenty randomly selected, isolated upper limbs fixed in 10% formalin solution were dissected.
Results
The radial artery was found to have a high origin in 9.2% of total number of the limbs: two cases from the axillary artery; nine cases from the brachial artery. Anastomosis between the brachioradial and “normal” brachial arteries in the cubital fossa was also frequently observed (54.6%). The anastomosis (“cubital crossover”) was dominant in one case, balanced in three cases, minimal in two cases, and absent in five cases.
Conclusions
The brachioradial artery may originate from the brachial and, less frequently, from the axillary artery. Anastomosis between the brachioradial and “normal” brachial arteries in the cubital fossa may be dominant, balanced, minimal, or absent. A complete radioulnar arch was found more often when the brachioradial artery was present as a variant.
