Retrograde endovenous laser ablation of the great saphenous vein using the superficial inferior epigastric vein as access vessel illustrated by a case report.

Endovenous thermal ablation is a first-line treatment for symptomatic varicose veins due to truncal vein reflux. Ablation of an incompetent great saphenous vein is usually performed from distally, with the vein access at the lowest point of reflux, or just below the knee. Occasionally there are patients in whom the great saphenous vein is difficult to access distally for reasons such as small vein diameter, scar tissue, vasospasm, difficult anatomy or multiple attempts with haematoma formation. In such cases, we access the great saphenous vein in a retrograde fashion by percutaneous cannulation of the superficial inferior epigastric vein, passing the catheter into the great saphenous vein just distal to the saphenofemoral junction and then down the vein to the required distal position. Ablation can then be performed, stopping the ablation in the great saphenous vein just distal to the junction of superficial inferior epigastric vein and great saphenous vein. We present a patient to illustrate our technique.
