title: Pulmonary embolism with duplicated inferior vena cava.
abstract: Congenital anomalies of the inferior vena cava (IVC) are common and usually of little clinical significance. We report the unusual cases of two patients with pulmonary embolism from thrombosis of part of a duplicated IVC. Both caval anomalies were easily identified with ultrasound, and the patients were successfully treated with anticoagulants. We encourage the reporting of similar cases since knowledge of the contribution of IVC duplication to thromboembolic disease is unknown.
