Correlation between GSV diameter and varicose clinics

Abstract

Summary Background Great saphenous vein (GSV) incompetence is involved in the majority of cases of varicose disease. Stratification of venous disease severity is still difficult. This study aims to correlate GSV diameters with C of CEAP and the venous clinical severity score (VCSS). Methods Legs without GSV reflux (Control legs, Group 1) and legs with untreated isolated GSV reflux and varicose veins limited to the GSV territory (Group 2) were studied clinically and with duplex ultrasound in a prospective study. The GSV diameters were measured both next to the saphenofemoral junction (SFJ) and at proximal thigh (PT) and correlated to the C of CEAP and VCSS. Results The control legs-group 1 were: n=33, 6 male, mean age 53, mean BMI 26.The legs with reflux-group 2 were: n=78, 16 male, mean age 54, mean BMI 27.The mean diameters for the SFJ ( ± SD) for groups 1 and 2 were 6.4 ± 1.8 and 9.9 ± 3.4. For PT they were 3.6 ± 0.9 and 5.9 ± 1.8 respectively. In legs with reflux the SFJ diameter correlates strongly with the PT diameter (r=0.69) and moderately with the C of CEAP and VCSS; 0.42 and 0.45 respectively. The PT diameter correlates slightly better with the C of CEAP and VCSS than the SFJ diameter (0.55 and 0.57). The mean values of VCSS for groups 1 and 2 were 0.70. and 4.69. The C of CEAP and VCSS show a strong correlation among them with r=0.79 in group 2 and 0.80 in the whole sample. Conclusion The GSV diameters next to the SFJ and particularly at the PT in patients having reflux correlate strongly with both the C of CEAP and VCSS. Recording the GSV diameters at the SFJ and PT in a standardized way may improve comparison of published data and contribute to choice of treatment in the future.
