Abstract:
A 57-year-old woman was hospitalized because of gait disturbance and dysuria. Close examination revealed a cauda equina tumor at the level of L2 and L3. Tumor resection was performed, with posterolateral fusion and spinal instrumentation. On the eleventh day after the surgery, she experienced dyspnea and chest pain during standing and walking exercise. Pulmonary thromboembolism was diagnosed, based on: (1) blood gas analysis findings of hypoxemia and (2) defective images in both of the upper lobes on urgent pulmonary blood flow scintigram. Her clinical status improved with urgent thrombolytic therapy (with tisokinase and urokinase) and anticoagulation therapy (with heparin and warfarin), and her life was saved. When pulmonary thromboembolism occurs, early diagnosis by pulmonary blood flow scintigram and early thrombolytic and anticoagulative therapies are necessary. Special attention should be paid to symptoms of pulmonary thromboembolism in patients after spinal surgery.
