Pulmonary vein thrombosis
Pictorial
review of the pulmonary vasculature: from arteries to veins. Pulmonary venous thrombus. Axial contrast-enhanced CT image in a patient with non-small cell lung cancer demonstrating a filling defect within the left superior pulmonary vein (white arrow). Note extensive lymphadenopathy within the left hila and mediastinum (*) from metastatic involvement

Pulmonary vein thrombosis is a rare but potentially serious condition with a number of underlying possible etiologies.
Clinical presentation
Often the signs and symptoms are non-specific and can range from acute (pulmonary infarction) to more insidious (progressive or recurrent pulmonary edema). Patients may have dyspnea, hemoptysis, chest pain, fever, and/or hypoxemia.
Pathology
Etiology
Causes include:
- intrapulmonary neoplasm: considered most frequent cause
- as a complication of lung transplantation or lobectomy
- as a complication of radiofrequency ablation
- fibrosing mediastinitis
- mitral stenosis with a left atrial clot
- hilar torsion
- hypercoagulable state
- idiopathic
Treatment and prognosis
Anticoagulation use is thought to be doubtful in terms of clinical outcome but may avoid clot development in the left atrium and possibly promote recanalization of the affected pulmonary vein .
