Abstract
Background: Evaluation of variations of the vascular supply of the hand and forearm and clinical significance
for surgical procedures.
Material and methods: Arterial variations was performed on 30 adults upper limbs in the department of human anatomy of SUMPh „Nicolae Testemiţanu”, Chișinău, Republic of Moldova. The diameter of radial and ulnar arteries were evaluated at the level of the bifurcation of the brachial artery and the radiocarpal joint. Anatomical variations in the formation, topography, and branching pattern of the superficial palmar arch have been documented.
Results: In 78.5% of cases, the ulnar artery had a larger diameter than the radial artery, in 7.2% of cases the diameter of the radial artery was larger, and 14.3% of cases had equal diameters. When predominant supply was the ulnar artery the presence of the median artery was documented in 18.1% of cases. At the level of the radiocarpal joint
the ulnar artery had a larger diameter in 53.4% (1.5-4 mm) the radial artery was dominant in 13.3% cases (3-4 mm)
and in 13.3% of cases the diameters were the same (3.5-4 mm). On the right side, the radial artery was dominant in
79% of cases with the ulnar artery being dominant in 14% of cases, and in 7% of cases there was codominance. The
complete superficial palmar arch was present in 26.6% of cases with the I dorsal metacarpal artery in 6.6% of cases.
Conclusions: This study suggests that knowledge of variations in the branching pattern and diameters provides details of the forearm vessels for cases requiring invasive vascular procedures.
