SECONDARY ISCHEMIA IN MICROVASCULARFLAPS AND POSSIBLE WAYS OF ITS PREVENTION AND CORRECTION

A morphometric evaluation of the vascular bed in microsurgical flaps as well as microvascular flaps after their incorporation into the blood and the development of symptoms of secondary ischemia has been presented in the article. The purpose of this study: an experimental study of morphometric parameters of the main links of the vascular bed in the non-free and free epigastric flaps at different times after transplantation. Material and methods. The object of the study were white rats of both sexes weighing 180-200 g (n = 60), which made the operation: the transposition unfreeepigastric flap with various treatment options and transplant epigastric free flap. Clinical assessment of the skin-fascial flap condition early after the surgery was performed using following criteria: edema, capillary response, manifestation of the flap skin coverings desquamation, presence of the necrosis. Conclusion. Denervation unfreeepigastric pedicle flap was accompanied by imbalance of the vascular bed of the flap due to the dilation and tortuosity of the axial artery and its absence (crimp) in the axial dilated vein;reperfusion epigastric free flap was accompanied by a significant dilatation of convoluted axial vessels with a fatal deficiency of its capillary perfusion.
