The ultrasonographic diagnosis of lymph node varicose veins in the groin - an overlooked missing link in chronic venous disease?

AIM: Chronic venous disease is a common pathology characterized by valvular incompetence and venous hypertension. The venous network of the lymph nodes at the Scarpa triangle connects the superficial and the deep venous systems. This study aimed to describe infrainguinal intranodal venous dilatations and to evaluate the connection with peripheral venous disease.

MATERIAL AND

METHODS

The study included 183 subjects (116 women, 67 men) who underwent Doppler ultrasound examinations of the venous system of the inferior limb in the context of chronic venous disease. The diagnosis of lymph node varices was based on well-defined criteria and the severity of the lymph node varices was established using an original classification.

RESULTS

There was a statistically significant, moderately strong association, between the presence of intranodal varices and the great saphenous vein reflux (φ=0.341, p=0.000). There was a moderate-to-high positive correlation between intranodal varices and the chronic venous disease stage (rrb=0.457, p=0.000).

CONCLUSIONS

Patients with more advanced stages of chronic venous insufficiency have a higher probability of presenting intranodal varices. Lymph node venous network identification could considerably impact clinical decision-making and treatment choices.
