Objective: to evaluate the safety of performing the procedure of superselective balloon embolization of a segmental renal artery before resection of the kidney regarding its neoplasm.

Materials and methods: to evaluate the effect of the balloon occlusion procedure on the state of the vascular wall, as an experimental model, 5 patients with malignant kidney tumors of the T1N0M0 stage with a central tumor location and T3N0M0 were included in the study. branches of the renal artery. Coronary balloon occlusion was performed until blood flow stopped in the corresponding kidney segment. On the autopsy study recorded changes in the vascular wall and perivasal changes in the tissue surrounding the lobar artery with a balloon. The preparations were dyed with hematoxylin-eosin, an increase of 5 x 0.12 and 10 x 0.25.

Results and discussion: as a result of superselective balloon embolization of the renal artery, in no case was there any significant damage to the walls of the renal vessels, which is due to the similar structure of the walls of the renal and coronary arteries. Perivascular changes consisted in microhematomas due to rupture of the vaso-vasal microcapillaries accompanying the lobar renal artery at the site of application of balloon occlusion.

Conclusion: superselective balloon embolization of the segmental renal artery during resection of the kidney for a neoplasm is not accompanied by significant damage to the walls of the blood vessels of the kidney and can be proposed for widespread use in clinical practice.
