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.

Congenital anomalies of the inferior vena cava such as absence or atresia are uncommon vascular defects and result from aberrant development during embryogenesis. We report a case of a young female patient affected by proximal deep venous thrombosis (DVT) complicated by liver and pulmonary embolism; subsequent extensive evaluation revealed the congenital absence of infrarenal inferior vena cava, with emboli probably occurring through collateral veins. Accordingly, in young patients with idiopathic DVT of the lower extremities and pelvic veins, the presence of inferior vena cava abnormalities should always be considered and investigated, together with classic coagulation factors, as a factor predisposing to thromboembolic complications.

Various congenital and acquired anomalies may affect the pulmonary arteries in adult patients. Congenital anomalies (proximal interruption, anomalous origin of the left pulmonary artery [pulmonary artery sling], and idiopathic dilatation of the pulmonary trunk) are usually found incidentally at chest radiography or computed tomography (CT). Acquired anomalies include diffuse or focal enlargement of the arteries because of pulmonary hypertension, aneurysm, and intravascular pulmonary metastasis; decreased arterial diameter because of bronchial carcinoma, mediastinal fibrosis, and Takayasu arteritis; and intraluminal filling defects due to pulmonary thromboembolism and pulmonary artery sarcoma. An awareness of the radiologic manifestations of the disease entities and potential pulmonary artery complications secondary to infection or vasculitis may enable an early diagnosis. CT angiography is becoming the standard method for evaluating patients in whom the presence of pulmonary embolism is suspected. CT assessment of the extent of heart effects in patients with pulmonary hypertension and pulmonary embolism is particularly important because such effects largely determine the prognosis.
