Abstract

Objective. To evaluate the significance of tissue oximetry data in the choice of the target angiosome when planning endovascular intervention on the arteries of the lower extremities in patients with diabetic foot syndrome (DFS).

Material and methods. 36 patients with DFS, tissue oximetry was alternately measured in the projection of angiosomes using the FORE-SIGHT® MS-2000 device (CASMED) and the ankle-brachial index (АBI) was measured in the projection of in the posterior and anterior tibial projections. Tissue oximetry was measured on the dorsum of the foot and the plantar surface of the foot in 20 healthy volunteers.

Results. Patients with DFS, there was a significant (p < 0.05) decrease in StO2 on the dorsum of the foot (9.5%) and sole (11.2%), compared with the results in volunteers. A strong correlation was obtained between the presence of a trophic defect only on the dorsum of the foot and a decrease in StO2 values at points: I (η2= 0.854, p = 0.005), II (η2= 0.819, p = 0.04), IV (η2= 0.919) and V (η2= 0.775, p = 0.039); moderate at point III (η2= 0.677, p = 0.041), as well as between the presence of a trophic defect on the back of the foot and a decrease in ABI values on anterior tibial projections (η2= 0.369, p = 0.011). We did not find such a relationship in other angiosomes.

Сonclusion. Baseline values of tissue oximetry in patients with DFS were significantly lower than in volunteers. We have not found a direct relationship between the presence of a trophic defect in a particular angiosome and a decrease in saturation in the same localization.
