Summary
This study investigated hand arterial variations, focusing on superficial palmar arch vessel diameters. Results show significant differences in radial and ulnar artery sizes, offering insights into hand vascular anatomy.
Area of Science:
- Anatomy
- Vascular Anatomy
- Human Anatomy
Background:
- Anatomical variations in hand arteries are frequently studied.
- Data on the diameter of superficial palmar arch contributing vessels and branches are scarce.
Purpose of the Study:
- To evaluate arterial variations in the hand.
- To specifically analyze the diameter of superficial palmar arch contributing vessels and their main branches.
Main Methods:
- Analysis of 46 male embalmed human cadaver hands (21 right, 25 left).
- Detailed examination of the superficial palmar arch and its contributing vessels.
Main Results:
- Complete superficial palmar arches were observed in 43% of right and 52% of left hands.
- The radial artery was significantly larger than the ulnar artery.
- The ulnar artery was larger than the superficial branch of the radial artery.
- Variations were more prevalent on the radial side and in left hands.
Conclusions:
- The study provides detailed measurements of superficial palmar arch vessels.
- Significant diameter differences exist between the radial and ulnar arteries.
- Common digital artery diameters were consistent regardless of arch completeness or median artery presence.
