Abstract
Aberrant origin of ulnar artery that potentially changes its normal
anatomical relationship is considerable rare. But when present, it must
never be overlooked before carrying invasive procedures on the
anteromedial aspect of the arm and forearm by the clinician. This would
avoid unprecedented iatrogenic loss of part or entire distal part of the upper
limb due to loss of arterial blood supply. While doing the normal dissection
of the left upper limb on the 35 year old female cadaver, medical students
saw a strangely and superficially placed ulnar artery that arose from the
brachial artery way up within the upper part of the middle 3rd of the arm.
This superficial ulnar artery coursed within the deep brachial and antebrachial
fascia, making it superficial to all flexor muscles of the flexor
compartment of the forearm. It only resumes its normal course at the wrist
joint distally. The brachial artery coursed normally and bifurcated at the
cubital fossa to give radial artery laterally and common interosseous artery
medially. On the other hand, the right upper limb had normal arterial
patterning.
