RESUMEN
A 72-year-old man underwent video-assisted thoracoscopic left upper lobectomy for small cell lung cancer. After 16 days, he experienced epigastric abdominal pain and vomiting, and was taken by ambulance to our hospital. Contrast-enhanced computed tomography (CT) showed a propagation of thrombus in the stump of the left superior pulmonary vein (LSPV) complicated with splenic infarction. The patient received anticoagulation therapy with heparin and warfarin, and further progression of the thrombus or any systemic embolic event was not observed during hospitalization. Here, we report a patient presenting with LSPV thrombosis complicated with splenic infarction after video-assisted thoracoscopic surgery (VATS), and describe several months follow-up CT imaging results after administration of an oral anticoagulation therapy.
