Summary
This study found unusual high origins of the radial artery in both upper limbs, with distinct variations in arterial patterns and palmar arch contributions, offering insights into embryologic development.
Area of Science:
- Anatomy
- Embryology
- Vascular Biology
Background:
- Anatomical variations in the upper limb vasculature are common.
- Understanding these variations is crucial for surgical procedures and interpreting imaging studies.
- The radial artery typically arises from the brachial artery in the upper arm.
Observation:
- A dissection revealed an abnormally high origin of the radial artery bilaterally.
- The right radial artery originated 2 cm superior to the median nerve roots.
- The left radial artery originated 3 cm distal to the profunda brachii artery origin.
Findings:
- Right hand: Radial and ulnar arteries contributed equally to superficial and deep palmar arches.
- Left hand: Superficial palmar arch predominantly formed by the ulnar artery; deep arch by the radial artery.
- These high radial artery origins are linked to embryologic development, differing from other common variations.
Implications:
- Highlights the importance of recognizing anatomical anomalies in clinical practice.
- Provides a case study for understanding human arterial development variations.
- Contributes to the anatomical database for the upper limb, aiding in surgical planning and diagnosis.
