PATIENTS AND METHODS: We examined a total of 30 patients presenting with atherosclerotic-genesis occlusive lesions of lower limb arteries and symptomatic intermittent claudication. Five patients were examined in the postoperative period. All patients were subjected to quantitative analysis of crural muscle perfusion in the pre- and postoperative periods, determining the time of onset of contrast medium accumulation and the time to the peak of intensity.RESULTS: Contrast-enhanced ultrasound examination demonstrated that in patients with occlusive lesions of lower-limb arteries the start of contrast medium accumulation appeared to occur later than in apparently healthy people: on second 30-88, depending on the degree of limb ischaemia. The contrasting time-to-peak was also increased (from 36 to 120 s). In the postoperative period all patients were found to have improved perfusion of the crural muscles, which was confirmed by a decrease in time-to-peak contrasting.CONCLUSION: Contrast-enh
