CT-guided preoperative hookwire localization of lung nodule in video-assisted thoracic surgery / 中国肿瘤临床

ABSTRACT

Objective:To explore the feasibility and safety of CT-guided hookwire localization of small lung nodule in video-as-sisted thoracic surgery. Methods: Preoperative localization of small lung nodule was performed using the CT-guided hookwire tech-nique, followed by video-assisted thoracic surgery in the wedge resection. The next mode of operation depends on the results of frozen biopsy. Results:Preoperative localization with CT-guided hookwire was performed in 34 patients between February 2012 and March 2014. The diameter of lung nodule ranged from 5 mm to 22 mm. CT-guided hookwire localization was successful in all patients, with a median positioning time of 23 min. Puncture needles were detached from two of the total patients during the surgery, and three other pa-tients showed pneumothorax by CT scan after localization. Conclusion:Preoperative hookwire localization of small lung nodule is an accurate and safe approach to improve the rate of wedge resection in video-assisted thoracic surgery.
