| الوصف: | Objective: To evaluate the pathway of reflux in incompetent long saphenous veins (LSVs), paying particular attention to the role of longitudinal saphenous tributaries in the thigh (accessory saphenous veins, ASVs). Design: Prospective study in a group of patients with primary varices. Comparison with the anatomical patterns in a group of normal subjects. Setting: Private phlebology practice. Patients: Sixty-seven patients with primary varices (100 limbs) and 66 subjects without varices and with competent saphenous veins (120 limbs). Methods: Duplex ultrasound evaluation of the saphenous system in the thigh of patients and healthy subjects. The ‘eye’ ultrasonographic sign was used as the marker to distinguish the LSV from the longitudinal tributary veins of the thigh. Results: In 57% of limbs in patients with varices, reflux followed the saphenous vein, while in 43% the reflux spilled outside the LSV into an ASV (h or S types). When reflux followed the saphenous vein, no large calibre ASVs could be observed. In 30% of limbs in control subjects a parallel tributary vein with a similar calibre was found joining the LSV. Conclusion: Clinically visible varices in the thigh rarely comprise the LSV itself, but are usually dilated ASVs, the reflux stream passing from the proximal LSV into a more superficial ASV. The distal LSV running parallel beneath is often competent. In subjects with healthy LSVs, a large competent tributary vein is already present in the thigh in 30% of cases. This suggests that superficial deviation of reflux flow into an ASV in patients with varices may not arise from haemodynamically acquired changes, but could have a congenital origin. This could even be a predisposing factor in the development of varices. |
