A Case of Pulmonary Thromboembolism Associated with Deep Vein Thrombosis of the Upper and Lower Extremities after Lung Cancer Surgery

Abstract

A 83-year-old man, underwent a left upper lobectomy after diagnosis of lung cancer. He had a syncope attack on the 15th postoperative day. A contrast CT showed thrombi in his peripheral right pulmonary artery and thrombotic occlusion of left internal jugular vein and left subclavian vein. The stenosis of left brachiocephalic vein between sternum and aortic arch was detected before operation. Duplex scanning revealed thrombus with low–moderate echogenicity in left lower limb soleal vein. He received continuous infusion of therapeutic unfractionated heparin, followed by oral rivaroxaban, thus achieving an improvement of thrombosis. We report a rare case of pulmonary thromboembolism associated with deep vein thrombosis of the upper and lower extremities after lung cancer surgery.
