title: [Importance of the external saphenous vein in pathology].
abstract: Incompetence of the internal saphenous crook is not unconditionally the cause of varices. Most frequently the dilatations begin in the calf and climb progressively towards the thigh thereby dilatating the internal saphenous vein. This is explained by the quite unique nature of the anatomy of the popliteal fossa and its relationship with its vascular and nervous content. The sciatic popliteal nerve, the external and paired saphenous veins often present structural and anatomical variations. The deep range of these veins is often badly understood and explains the lack of success after stripping, staged resection or surgical sclerosis.
