A variant of the classical superficial brachioulnoradial artery: morphology and clinical significances.

We report a superficial brachioulnoradial artery (SBURA) presenting as a variant of the normal, originating from the proximal third of the right brachial artery of a 75-year-old female cadaver which bifurcated yielding a brachiointerosseous artery laterally and a SBURA medially, and the latter bifurcating 5 cm proximal to the elbow yielding a brachioradial artery laterally and the superficial brachioulnar artery medially, resulting in the formation of three instead of two brachial arteries as in the classical SBURA said to bifurcate at the elbow into the radial and ulnar arteries. Clinical implications of this variant are discussed.
