Introduction. Data about the possible topographic variations of arterial and venous vessels belonging to the different areas of the human upper limb is very important for the development of endovascular surgery.
The objective of the study was to reveal the anatomical variability of the superficial and deep veins of the upper limb in human fetuses of 4-10 months.
Materials and methods. The topographic and anatomical features study of the superficial and deep veins belonging to the upper limb was carried out on 46 specimens of human fetuses of 81.0-375.0 mm parietal-coccygeal length (PCL) using the methods of macromicroscopic dissection, vascular injection and morphometry.
Results. In human fetuses, there is a wide range of individual anatomical variability of the superficial and deep veins in the upper limb, which is characterized by bilateral asymmetry of their topography, quantity, as well as the formation of various intrasystemic and intersystemic venous anastomoses in the form of the letters «I», «N», «V», «Y» in the antebrachial and anterior ulnar areas. The basilic and cephalic veins in the anterior and posterior antebrachial, cubital and brachial areas connect with each other, as well as with the deep veins of the upper limb.
Conclusions. In human fetuses, the magistral/trunk form prevails in veins of the upper limb, which is characterized by the presence of a large venous vessel of straight or curved shape with a small number of anastomoses. The magistral venous vessel is located on the majority of its territory and contains a small number of tributaries small in diameter. The net-like shape of the veins of the upper limb, an example of which is the dorsal venous network, is distinguished by the number of short venous vessels that lie almost parallel to each other, have the same direction and merge consequently.
Keywords: veins, topography, blood supply, fetus, upper limb.
