[Collapse of the contra-lateral lung after computed tomography-guided marking]

We are performing preoperative percutaneous computed tomography (CT)-guided placement of hook-wires to localize small lesions on the day before thoracoscopic surgery. We report a case of collapse of the contra-lateral lung after CT-guided marking. A 69-year-old man was referred to our department for surgical intervention of multiple small lung tumors in the right upper lobe. At the age of 66, he underwent esophagectomy for esophageal cancer. CT-guided marking was undergone for both tumors on the day before surgery. After marking, collapse of the contra-lateral (left) lung was occurred. Left chest tube was placed in order to maintain adequate ventilation during the operation. Operative findings revealed that sealing test after resections of the lung could not be performed because the fistel to the left chest cavity at the inferior mediastinum after esophagectomy was detected.
