Primary varicose veins: the sapheno-femoral junction, distribution of varicosities and patterns of incompetence.

Objective: to determine the patterns of long saphenous vein (LSV) disease in primary varicose veins (VVs).

Design: a retrospective analysis of venous duplex scans performed on patients referred for treatment of primary VVs.

Methods: analysis was made of sapheno-femoral junction (SFJ) incompetence, non-SFJ incompetence, segmental and perforating vein incompetence, distribution of varicosities, deep venous insufficiency, and short saphenous incompetence.
