ABSTRACT
BACKGROUND: Complex aberration in lung is rare, which may increase risk of vascular injury and cause ligation of wrong pulmonary vein or bronchus by mistake during lung surgery, and result in sever complication like pulmonary congestion or atelectasis. CASE SUMMARY: A 44-year-old female was admitted for a ground glass nodule (24 mm in diameter) in her right upper lobe. Video-assisted thoracoscopic (VATS) right upper lobectomy with lymph nodes dissection was performed. During operation, we simultaneously identified extremely rare aberrations of right preeparterial bronchus, right upper lobe vein behind pulmonary artery and right middle lobe vein drained into left atrium in this patient. The patient was well recovered and discharged at the postoperative-day 4. CONCLUSION: Preoperatively, three-dimensional reconstruction can help to identify inconspicuous variation of pulmonary vessels and bronchus effectively. During lung surgery, if anatomic aberration is suspected, careful dissection of vessels and bronchus will help to confirm whether there is an aberration or not.
