Task: Answer Verification
Input (English): Question: Is lower extremity autologous vein bypass for critical limb ischemia adversely affected by prior endovascular procedure?
Answer: Overall operative mortality, patency rates, and limb salvage for autologous vein LEB in CLI patients continue to be excellent in the endovascular era and are not necessarily affected by a prior ipsilateral endovascular procedure. Long-term survival remains poor in CLI patients requiring LEB.
Output (English): no
