PREDICTING THE OUTCOMES OF TIBIAL ARTERY REVASCU-LARIZATION IN SEVERE ATHEROSCLEROTIC LESIONS USING LU-MINESCENCE SPECTROSCOPY
ABSTRACT
Background. Predicting the outcomes of tibial artery revascularization o in severe atherosclerotic lesions is an urgent challange of angiosurgery.
Purpose. To determine the possibility of predicting the results of arterial recon-struction in severe atherosclerotic lesions of the tibial arteries with trophic defects using luminescent spectroscopy.
Materials and methods. A 14-day prospective study was conducted on 30 pa-tients who were treated in the Department of Vascular Surgery of the Republican Clinical Medical and Surgical Center in Nalchik. In the preoperative period, the in-tensity of luminescence of inflamed tissues was measured in all patients at the level of existing trophic ulcers using laser-induced ultraviolet violet photoluminescence spectroscopy. According to the luminescent signal level, the patients were divided into 2 groups: gGroup 1 — with a signal level in the projection of a ulcerative defect 0.3-0.5 x 105 photons; Group 2 — with a signal level of 0.5-0.7 x105 photons. In addition, subgroup A underwent conservative therapy with alprostadil 40 mcg twice a day intravenously during the entire follow–up period, while subgroup B underwent hybrid surgery with angioplasty of the key artery of the tibia. The size of trophic defects on the lower leg was measured using the “AnalyRan” software.
Results. The healing rate of trophic ulcers healing differed significantly in Group 1 starting from Day 11, with a higher rate in surgically treated patients (p<0.05). In Group 2, the situation was opposite, the statistically significant healing rate of trophic defects in the subgroup with conservative alprostadil therapy exceeded that in subgroup B, from the 9th day of the study (p<0.05). As the wound healing rate increased, the rate of granulation tissue formation also increased, which was in-versely related to the amplitude of the measured tissue luminescence.
Conclusion. In patients with stenoclusive lesion of the lower leg arteries and trophic defects, with an autoluminescence amplitude of 0.3-0.5x105 photons, indi-rect revascularization and conservative treatment is preferable, and with an ampli-tude of 0.5-0.7x105 photons, direct revascularization of the angiosomal artery is preferable.
