The Anatomic Figure of Saphenofemoral Junction in Primary Varicose Vein

ABSTRACT

PURPOSE: The purpose of this study is to measure the diameter of saphenofemoral junction (SFJ) by using duplex scan and to assess the different anatomic characteristics of SFJ according to the clinical manifestation. METHODS: 100 Limbs of 77 patients with varicose veins due to greater saphenous vein (GSV) were assessed prospectively about sex, symptom, disease duration, morphology of varicose vein. The diameter of GSV (GSVD), SFJ, femoral vein (FVD) and the ratio of each value-GSV/FV (GFDR) and SFJ/FV (JFDR)-were measured by color-flow duplex scanning. Findings were compared with clinically normal 20 control limbs. RESULTS: The mean value of GSVD, FVD, SFJ, GFDR, JFDR in patients group were different from that of control group with statistical significance except FVD. There were statistically significant differences in the mean value of GSVD, FVD, GFDR, JFDR between men and women. The mean value of GSVD, FVD, SFJ, GFDR, JFDR between symptomatic and asymptomatic group were not different statistically. The result of comparison according to the disease duration showed statistically significant difference, which the more duration of disease were longer, the more the mean value of SFJ were increased. In comparison of the findings according to the morphologic classification, there were no statistically significant differences in the mean value of GSVD, FVD, SFJ, GFDR, JFDR. CONCLUSION: Dilatation of SFJ may be related to the cause of varicose veins from the result that the mean value of SFJ was more increased in patients group than control group.
