THE ROLE OF VASA VASORUM IN BLOOD SUPPLY OF EPIGASTRIC FLAP(EXPERIMENTAL STUDY)

The importance of vasa vasorum of superficial epigastric artery (a. epigastrica superficialis) in the blood supply ofcentral area of epigastric skin-fascial flap is shown for the first time in this article.Objects of the study were white Wistar rats having the mass of 250-300 g (n = 84). The animals were divided into4 groups: animals of the I group (n = 21) underwent transposition of non-free epigastric flap without sympathectomyof vascular flap pedicle; the II group animals (n = 21) underwent transposition of non-free epigastric flap withvascular flap pedicle sympathectomy; the III group animals (n = 21) underwent elevation of non-free epigastric flapwith subsequent precision ligation in the vascular pedicle of arterial flap; the IV group animals (n = 21)underwentautotransplantation of free epigastric flap. Clinical assessment of the skin-fascial flap condition early after the surgery(1st-10th days) was performed using following criteria: edema, capillary response, manifestation of the flap skin coveringsdesquamation, presence of the necrosis.Conclusion: not only axial vessels but vessels of paravasal fat which supply central flap area take part in the bloodsupply of white rat epigastric skin flap.
