CTICasesSegmental Venous Infarction post-Lobectomy
Imaging findings
Post-lobectomy chest radiograph shows a sharply demarcated wedge of consolidation. CT shows non-perfusing segment of the middle lobe with patent arteries and bronchus but complete absence of venous drainage due to surgical ligation.
Key takeaways
Incomplete pulmonary fissures can lead to inadvertent surgical ligation of accessory draining veins (e.g., middle lobe vein draining into the superior pulmonary vein during upper lobectomy), causing segmental venous infarction.
