[Acute pulmonary embolism after radical operation for renal cell carcinoma with vena caval extension: a case cured by thrombolytic therapy].

: A 54-year-old man was hospitalized for a right renal tumor with intraluminal extension into the vena cava. He underwent radical nephrectomy with thrombectomy and regional lymphadenectomy. On the 8th postoperative day, he suddenly complained of dyspnea with tachypnea and cyanosis. Arterial blood gas analyses under an oxygen flow of 4L/min revealed PaO2 32.1 mmHg. Pulmonary angiography revealed filling defects in the right main pulmonary artery and left descending branch. Under the diagnosis of acute pulmonary embolism, thrombolytic and anti-coagulation therapy was performed and the patient recovered from the disease. We should be aware of pulmonary embolism as a postoperative complication of urological surgery.
