[Anatomo-topographic variants of the supraorbital artery]

The authors analyze the anatomy and topography of supraorbital artery variants in connection with intraarterial drug supply in vascular diseases of the eye. The possibility of atraumatic isolation of the supraorbital artery was demonstrated on section material (28 supraorbital vasculonervous bundles). In three fourths of the cases the diameter of the supraorbital artery was 0.6-1.5 mm in various age groups; this constancy is an important condition providing the catheter establishment in the vessel for intraarterial infusions. The possibility of lesser (less than 0.5 mm) diameters in the rest one fourth of cases and of a 'loose type' artery necessitate the elaboration of noninvasive methods for measurements of the supraorbital artery diameter before surgery on the vessels.
