Superficial brachioradial artery (radial artery originating from the axillary artery): a case report and embryological background
A case of anomalous terminal branching of the axillary artery, concerning the
variant called superficial brachioradial artery (arteria brachioradialis superficialis)
was described, with special regard to its embryological origin. The left
upper limb of a male cadaver was dissected in successive steps from the
axillary fossa distally to the palmar region. A variant artery, stemming from
the end of the third segment of the axillary artery, followed a superficial
course distally. It skipped the cubital fossa, ran on the lateral side of the
forearm, crossed ventrally to the palm, and terminated in the deep palmar
arch. This vessel is a case of so-called “brachioradial artery” (inexactly called
a “radial artery with a high origin”). The origin of the brachioradial artery
directly from the axillary artery belongs to the rare variants of the arterial
pattern of the upper limb. Its incidence is approximately 3%. Moreover, this
vascular variant was associated with another one concerning the brachial
plexus. The medial cutaneous nerve of the forearm joined the median nerve
in the middle third of the arm and ran further distally as a common trunk, as
the normal median nerve does. Anatomical knowledge of the axillary region
is crucial for radiodiagnostic and surgical procedures, especially in cases of
trauma. The superficially located artery brings an elevated risk of bleeding
complications in unexpected situations
