Pulmonary embolism and deep vein thrombosis complicating acute aortic dissection during medical treatment

Abstract

Acute aortic dissection of Stanford type A with intramural hematoma was diagnosed based on computed tomography (CT) findings in a 60-year-old man. During medical treatment, pulmonary embolism and deep vein thrombosis developed. Cr revealed thrombosis in the right pulmonary artery, and 99mTc pulmonary perfusion scintigraphy showed defects in the right lung field. CT showed thrombus in the common iliac vein. An inferior vena caval filter was placed because anticoagulation therapy was contraindicated. A CT scan before discharge showed no thrombus in the pulmonary artery or common iliac vein, but a newly captured thrombus was found inside the filter. © 2007 The Japanese Society of Internal Medicine.
