Rare Case of Variant Anatomy of Safenofemoral Junction in a Patient with Varicose Vein Disease

INTRODUCTION: Despite the fact that the anatomy of the venous system is considered to be rather variable, the area of saphenofemoral junction has the most permanent structure with rather rare anatomic variants — not more than 0.3%. At the same time, these particular variants create technical difficulties in surgical treatment. It is interesting that the frequency of iatrogenic damages and of occurrence of variant anatomy is comparable. It is also important to note that thromboembolic complications account for 18.3% of complications of the postoperative period, according to different sources. One of factors of these complications may be a long stump of the great saphenous vein, therefore, the stage of resection of the great saphenous vein is of primary importance. In the article, a variant of atypical topography of saphenofemoral junction in a female patient with varicose vein disease is considered. CONCLUSION: It should be said that taking into account probable anatomic variants of vessels, it is always necessary to perform a thorough examination of the patient using instrumental examination in the form of US diagnostics, to avoid intraoperative complications. Increase in the length of incision, use of inguinal access and marking the zone of SFJ can help avoid isolation of femoral arteries in patients with variant anatomy at the stage of resection of the great saphenous vein.
