Relationship Between Clinical Findings and Vena Saphena Magna Diameter and Insufficiency at Cruris

Abstract

Objectives: The aim of our study is to investigate the relationship between the severity of VSM (vena saphena magna)insufficiency, diameter, and clinical findings, especially at cruris.Methods: Our study was performed between November 2016 and May 2020, retrospectively with 194 low extremities.VSM diameter measurement and reflux were evaluated at three levels during the examination with Colour DopplerUltrasonography (CDUS), sapheno-femoral junction(SFJ), midfemoral segment and proximal to the cruris, standing andlying. The patients without venous insufficiency constitute the control group.Results: The mean VSM diameter is 5.51mm in SFJ, 4.08mm in the thigh and 3.47mm in the cruris. The increase in VSMdiameters was statistically significant(p<0.01) at all of the three levels, compared to control group(p<0.01). The VSMdiameter difference was found to be high in the group with insufficiency in lying position examination especially in theSFJ and thigh level (p<0.01). The VSM diameter in the cruris is low but significant(p<0.05). Correlation between SFJ andcruris is present between diameter increase differences and clinical findings at all of levels. Therefore, in those patientsin whom diameter in SFJ, cruris localizations increased in standing position, skin lesions are more frequent (p<0.01).Conclusion: Clinical findings correlate with VSM insufficiency and diameters. The skin lesions correlate with the diameter increase during evaluation in standing position. Diameter change is greater in the SFJ and thigh than significantchange at cruris. Finally, the VSM diameter increase in cruris correlates more with skin lesions.
