Summary
An unusual high origin of the radial artery was observed in a cadaver
Area of Science:
- Anatomy
- Vascular Surgery
- Surgical Education
Background:
- Variations in upper extremity arterial anatomy can impact surgical planning.
- Accurate knowledge of the radial and ulnar arteries is crucial for reconstructive microsurgery.
Observation:
- The radial artery originated unusually high from the brachial artery, 16.7 cm below the coracoid process.
- It crossed the brachial artery to its lateral side, running anterior to the biceps brachii aponeurosis.
- The brachial artery trifurcated into ulnar, anterior interosseous, and posterior interosseous arteries, with an absent common interosseous artery.
Findings:
- A high-origin radial artery with an aberrant course was identified.
- The brachial artery termination pattern was unusual, lacking a common interosseous artery.
Implications:
- This anatomical variation highlights the importance of detailed pre-operative assessment in upper limb surgery.
- Misidentification of the radial artery could lead to severe complications, such as limb loss, if mistaken for a vein during injection.
