[Distal arteritis of the legs: de-obstruction of the popliteal trifurcation]
Insights
For critical limb ischemia, surgical exploration of the popliteal artery, even after failed arteriograms, can improve outcomes. This approach led to a 78.5% five-year limb salvage rate in patients with critical leg and foot ischemia.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Context:
- Critical leg and foot ischemia often presents diagnostic challenges with conventional arteriography.
- The popliteal artery and its branches are frequently not visualized, complicating treatment planning.
Purpose:
- To investigate the patency of the popliteal artery in cases of critical limb ischemia where arteriograms are inconclusive.
- To evaluate the efficacy of aggressive surgical management, including direct popliteal artery exploration, for limb salvage.
Summary:
- Study involved examining amputated limbs to assess popliteal artery patency and the potential for clot retrieval.
- Fresh clot retrieval from the popliteal artery was found to enable optimal outflow for femoro-popliteal bypass.
- Systematic surgical exploration of the popliteal artery was implemented for critical limb ischemia cases with non-diagnostic arteriograms.
Impact:
- Aggressive surgical management, including popliteal artery exploration, achieved a 78.5% five-year limb salvage rate.
- This strategy offers a viable alternative for limb preservation when standard imaging fails to identify treatable arterial segments.
Abstract:
Conventional arteriograms for critical leg and foot ischemia frequently do not opacify the popliteal artery and its branches of division. We have studied the patency of the popliteal artery on amputated limb and we have seen that in a great number of cases, it was possible to retrieve fresh clots from the popliteal artery in order to obtain a optimum outflow and to perform a femoro-popliteal bypass. Since the completion of this study, we systematically explore the popliteal artery surgically in case of critical leg and foot ischemia even in the cases where arteriogram failed to demonstrate a patent artery. This aggressive surgical management resulted in a 78.5% five year limb salvage rate.
