| Abstract | Background: Acute tumour embolism to the popliteal artery resulting in limb-threatening ischemia is a rare complication of neoplastic disease. Generally, tumors embolize to the pulmonary circulation via the venous system. In this case, the originating tumor was a lung cancer of a large size and advanced stage that had invaded the left atrium of the heart and disseminated in the systemic circulation. The tumor likely fragmented, resulting in showering to the right popliteal artery, superior mesenteric artery, and left renal artery, which is a unique presentation of tumor embolism. Case report: We present a case of a 62-year-old Caucasian gentleman with a large left lower lobe squamous cell lung cancer that had invaded into the left atrium via the pulmonary veins. He presented with acute limb threatening ischemia. A computed tomographic angiogram revealed an occlusion of the left popliteal artery as well as embolization to the superior mesenteric artery and the right renal artery. He was started on intravenous heparin and underwent an emergency popliteal embolectomy and calf fasciotomies, which was limb saving. His fasciotomy wounds were closed after 1 week and he was discharged on anticoagulation. Conclusion: This is a rare case of tumor embolism resulting in both an embolectomy and calf fasciotomies. In the light of such cases, we suggest that tumors invading the bloodstream should be considered high risk for embolization and hypothesize that prophylactic antithrombotic therapy may avoid major morbidity. |
