Acute limb ischemia is characterized by a rapid reduction in the blood flow in the lower limb. It may be due to peripheral artery occlusion or a bypass graft. The symptoms include toenail thickening, numbness or pain in the legs, open sores, dry gangrene, and reduced or absent pulse in the feet or legs.
Thrombectomy removes a clot at the site of formation, while embolectomy removes blood clots when the clot travels to another location.
The causes of acute limb ischemia include thrombosis, embolism, major trauma, thrombosis due to a popliteal artery aneurysm, and thoracic outlet syndrome.
