CTICasesPost-Lobectomy Pulmonary Vein Stump Thrombus
Imaging findings
A contrast-enhanced chest CT demonstrates a soft tissue density filling defect within the left inferior pulmonary venous stump following a prior left lower lobectomy.
Key takeaways
Thrombus formation in a pulmonary venous stump is a rare post-lobectomy complication that occurs more commonly in the left superior pulmonary vein but can occasionally affect the inferior vein stump. Unlike pulmonary arterial stump thrombi, venous stump thrombi pose a direct risk of systemic arterial embolization and stroke, and must be recognized on routine surveillance imaging.
