Percutaneous Saphenous Vein Arterialization

Abstract

Purpose

In patients with no-option critical limb-threatening ischemia, venous foot arterialization can be considered the last chance before major amputation. Up until now, a really significant limitation of endovascular arterialization compared with surgery was the possibility to obtain arterial flow into the foot only through the deep plantar network.

Technique

Two 5-mm snares are placed: one in the proximal tibial artery and the other in the great saphenous vein. After passing through these snares with a needle and a guidewire and closing the snares, the guidewire is pulled through the proximal arterial sheath and the distal venous sheath. Thus, the arterial-venous connection is created. A covered stent is, then, placed between the artery and the vein to avoid leakage.

Conclusions

Based on our knowledge, this is the first described totally percutaneous arterialization of the superficial dorsal venous foot system, through reverse flow in the great saphenous vein.
