Posterior approach for simultaneous access to the popliteal and anterior tibial arteries: applications to distal arterial bypass.
Arterial surgery to salvage the lower limb tends to make use of the great saphenous vein, harvested with the subject in the supine position. If this is not possible the small saphenous vein is used, harvested with the subject in the prone position, however this requires a perioperative modification of the procedure. A bypass between the popliteal and anterior tibial arteries can be performed using either a lateral or a medial and lateral approach with the patient supine. In the event of trophic disorders of the lateral compartment of the leg, these approaches are not applicable. In such cases we propose a single posterior approach. The single posterior approach was used on 10 lower limbs from 5 cadavers in the prone position. Approach to the lower part of the popliteal artery was undertaken posteriorly between the two heads of gastrocnemius. The small saphenous vein was entirely dissected 10 cm above the lateral malleolus, the Achilles tendon and short fibular vessels were retracted medially to expose the interossous fascia, which was divided over 10 cm. Medial rotation of the limb by 30 degrees exposed the anterior tibial artery. For 3 of the lower limbs an 8 cm fibular resection was necessary, whereas on the remaining 7 medial rotation enabled excellent exposure of the anterior tibial artery. The single posterior approach to the anterior tibial artery can be applied in cases requiring distal bypass, using the small saphenous vein, between the inferior part of the popliteal artery and the anterior tibial artery.
