Treatment of Varicose Long Saphenous Veins with Sclerosant in Microfoam Form: Long-Term Outcomes

Abstract

Objective:

To determine whether the injection of sclerosant in microfoam form offers a clear alternative to surgery in large varices of the lower extremities.

Design:

Retrospective observational follow-up study (3–6 years).

Patients:

Five hundred lower limbs in which pretreatment duplex ultrasound demonstrated insufficiency of sapheno-femoral junctions (diameters 9–32 mm) and long saphenous veins.

Main outcome measure:

Obliteration and subsequent disappearance of treated veins.

Results:

After ≥ 3 years follow-up, 81% of treated varicose long saphenous veins were obliterated and 96.5% of superficial branches disappeared. The obliteration of saphenous veins required one injection in 86%, two in 10.5% and three in 3.5% of cases. There were no serious complications such as deep vein thrombosis Pulmonary embolism.

Conclusion:

The quality and stability of outcomes and ease of repeat treatments when required may make sclerotherapy with microfoam a therapeutic approach of choice for the functional and anatomical elimination of extensive pathological venous areas.
