CTICasesIatrogenic Lobar Ischemia
Imaging findings
Serial chest radiographs and CT post-thymic carcinoma resection show progressive, dense left upper lobe consolidation with posterior bulging of the major fissure. The left superior pulmonary vein and upper lobe branches of the pulmonary artery are occluded at the staple line.
Key takeaways
Difficult thoracic surgeries involving mediastinal mass resection (such as thymic carcinoma) can result in accidental or necessary ligation of lobular vessels. Ligation of pulmonary arteries and veins at the staple line causes acute, severe lobar ischemia, requiring completion lobectomy.
