Thromboembolectomy of arteries explored at the ankle.

Experience with 11 cases of thromboembolectomy of leg arteries explored at the ankle is presented. Patency was established in 19 of 23 arteries (83%), resulting in salvage of 11 of 14 limbs (79%). This experience documents success of this technique with follow-up ranging from 2 to 70 months (mean followup, 24.7 months). Current indications for the procedure include 1) incomplete extraction of thrombus via the popliteal trifurcation, 2) incomplete transfemoral extraction of thrombus with restoration of a popliteal pulse, and 3) thromboembolus initially confined to the infrapopliteal arteries.
