Insights
Severe limb ischemia can be treated with an uncommon crossover bypass to the lateral femoral circumflex artery. This indirect revascularization strategy offers a viable option for improving lower extremity perfusion in complex arterial occlusions.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Peripheral Artery Disease
Background:
- Severe limb ischemia presents significant challenges in revascularization.
- Extensive arterial occlusion necessitates innovative surgical approaches.
- Collateral circulation plays a crucial role in maintaining limb perfusion.
Purpose of the Study:
- To describe an uncommon crossover bypass strategy for severe right limb ischemia.
- To evaluate the efficacy of indirect revascularization via the lateral femoral circumflex artery.
- To present an alternative treatment option for complex lower extremity artery occlusions.
Main Methods:
- A 78-year-old male patient with stage 3 (Fontaine IV, Rutherford 5) right limb ischemia was treated.
- A crossover bypass was performed from the left common femoral artery to the right lateral femoral circumflex artery.
- This approach aimed to enhance perfusion through well-developed collateral circulation.
Main Results:
- The crossover bypass successfully utilized the lateral femoral circumflex artery as an outflow.
- Indirect revascularization via collateral pathways improved lower extremity perfusion.
- The procedure demonstrated the feasibility of this uncommon bypass strategy.
Conclusions:
- Bypass using the lateral femoral circumflex artery is a viable option for limb salvage.
- Indirect revascularization can be effective in cases of extensive lower extremity artery occlusion.
- This surgical technique offers a valuable alternative for select patients with critical limb ischemia.
Abstract:
A 78-year-old man presented with severe stage 3 (Fontaine IV, Rutherford 5, W1 I3 FI0) right limb ischemia. Although his artery was completely occluded from below the right external iliac to the popliteal artery, collateral circulation from the right lateral femoral circumflex artery was well developed and supplied the lower extremity arteries. We selected an uncommon crossover bypass strategy with the left common femoral artery to the right lateral femoral circumflex artery to improve lower extremity perfusion via indirect revascularization. Bypass using the lateral femoral circumflex artery as an outflow is an option for patients with major lower extremity artery occlusions.
