THE PURPOSE
Determination of ultrasound criteria of diameters of intramuscular veins of the leg in normal and the degree of their ectasia in patients with chronic venous disease (CVD) of various clinical classes.
MATERIAL AND METHODS
During the period from 2015 to 2019, using ultrasound duplex scanning (USDS), 412 men and women who had no signs of varicose transformation of veins of the lower extremities (group 1) were examined, and 1203 patients with CVD were examined with their distribution in accordance with the international CEAP classification as follows: C0—C1 — 359 (29.8%) people (2nd group), C2—C3 — 570 (47.4%) patients (3rd group) and (C4—C6) — 274 (22.8%) examined (4th group). USDS was performed on PHILIPS-EPIQ 5G and 7G devices in B-mode with color Doppler mapping in the patient’s vertical position. Statistical analysis of the data obtained was performed using the IBM-SPSS-Statistica software package, which made it possible to analyze and compare quantitative indicators, as well as to carry out correlation and regression analyzes.
RESULTS
Statistical analysis of the data obtained showed that in the 1st group (variant of the norm) the diameter of the intramuscular veins of the leg according to USDS data at p=0.05, i.e. with an error tolerance of no more than 5% of observations, had corresponded to the digital value 0.35±0.06; in the 2nd group (C0—C1) — 0.45±0.06; in group 3 (C2—C3) — 0.79±0.15 and in group 4 — 0.81±0.16.At the same time, the statistically verified level of the median of diameters in these groups was, respectively, in the 1st group (variant of the norm) 0.35 cm; in the 2nd group (C0—C1) — 0.45 cm; in the 3rd group (C2—C3) — 0.79 cm and in the 4th group (C4—C6) — 0.81 cm. Comparable data were obtained when comparing the quartiles in each group and the study groups with each other. Based on the data obtained, the classification of the degree of ectasia of the intramuscular veins of the leg, depending on the established diameter of the veins, is presented for discussion.
CONCLUSION
Based on the obtained ultrasound data, it was found that the diameter of the intramuscular veins of the leg is normal and in patients with C0 — C1 is no more than 0.5 cm. With the development of varicose disease (C2—C3) and progressive CVI (C4—C6), the diameter of intramuscular veins exceeds 0.5 cm, with gradual ectasia of these veins up to 0.8 cm or more (p<0.05).
