摘　　要：BACKGROUND Globally,the estimated annual incidence of snakebites is approximately 5 million,and approximately 100000 deaths occur from snakebites annually.Local tissue reaction,haemorrhagic clotting disorder,nephrotoxicity,and neurotoxicity are very common effects of snake envenomation,but other rarer complications,such as thrombosis,may also occur as a result of underlying disease.In the treatment of snakebite patients,attention should be paid to the patient’s underlying diseases to avoid serious and catastrophic consequences secondary to snakebite.CASE SUMMARY We report a 69-year-old man with critical right lower extremity pain after left foot snakebite 10 d prior without intermittent claudication or atrial fibrillation history.He was diagnosed with acute right lower extremity arterial thrombosis,which may have been caused by coagulopathy after snakebite and lower extremity atherosclerotic occlusive disease.Lower extremity computed tomography angiography at another hospital revealed that the aortoiliac and femoral arteries had neither filling defects nor atherosclerosis,but the right popliteal artery was occluded 2.3 cm below the tibial plateau.The patient received emergency catheter-directed thrombolysis,but amputation was carried out 11 d after admission because the patient had been admitted to the hospital too late to save the extremity.CONCLUSION Acute ischaemia of the lower extremity due to snakebite is a rare event,and physicians should bear in mind the serious complications that may occur,especially in patients with atherosclerotic disease.
