Summary
This case report details multiple, unusual arterial variations in a single upper limb cadaver, highlighting anatomical anomalies on both sides. These findings contribute to understanding human vascular variability.
Area of Science:
- Anatomy
- Human Anatomy
- Vascular Anatomy
Background:
- Anatomical variations in the upper limb arteries are common but rarely present bilaterally and multiply.
- Understanding these variations is crucial for surgical planning and interpreting diagnostic imaging.
Observation:
- Multiple arterial variations were observed in a single cadaver's upper limbs.
- Right upper limb: Subscapular artery variation with an enlarged posterior circumflex humeral artery.
- Left upper limb: Anomalous origin of radial and ulnar arteries from the brachial artery, with an arciform anastomosis and atypical radial recurrent artery.
Findings:
- The study documented unusual proximal origins and branching patterns of upper limb arteries.
- Specific anomalies included variations in the subscapular, posterior circumflex humeral, thoracodorsal, circumflex scapular, brachial, radial, and ulnar arteries.
- Distal variations involved the absence of the first palmar metacarpal artery and early bifurcation of the second palmar metacarpal artery.
Implications:
- This detailed report expands the knowledge of upper limb arterial anatomy and its potential variations.
- Such anatomical anomalies have significant implications for vascular and orthopedic surgeries in the upper limb.
- Awareness of these variations aids in preventing iatrogenic injuries and improving clinical outcomes.
