Clinical and ultrasound comparison in the great saphenous vein system at venous disease
Objectives. To perform the comparison of clinical and ultrasonic examination in the assessment of varicose veins of the lower limbs in the great saphenous vein system. Methods. 102 patients (102 limbs) with varicose veins of lower limbs (VVLL) of C 2-6 classes of chronic venous disease (CVD) were examined. The patients were subdivided into 4 groups: the 1st group (С 2, 3) – 30 patients, the 2nd (С 4) – 34, the 3rd (C5) – 22, the 4th (C6) – 16. At the ultrasound investigation the trunk diameters (D) of the large saphenous vein (LSV) on the thigh were registered as well as the extent of the vertical pathological refluxes, the number of the incompetent perforating veins (PV) and their summarized diameter (Σ D). Results. The average diameter of GSV in the 1st group was 7,2 ± 0,2 mm, in the 2nd and 3rd groups – 9,07 ± 0,12 mm and 10,6 ± 1,2 mm, in the 4th group –12,5 ± 1,22 mm. In the 1st group the extended reflux prevailed – 76,7%, in the 2nd – the subtotal one – 58,8%, in the 3rd and 4th groups – the total one – 54,6% and 87,5%. The average number of the incompetent PV of the thigh and shin increased from 2,1 ± 0,22 in the 1st group up to 4,8 ± 0,13 in the 4th group (р<0,05). The summarized diameter of PV between the 1st group – 6,1 ± 1,8 mm; the 2nd group – 6,1 ± 1,8 mm and the 3rd group – 11,0 ± 3,4 mm reliably differs (р<0,05); there were no reliable differences between the 3rd and 4th groups – 16,4 ± 5,8 mm (р>0,05). Conclusions. At VVLL in the GSV system with the CVD class increase, D of the GSV trunk, the extent of the vertical pathological reflux, the number of PV and Σ D of PV also increase.
