Microcoil locating related complications and impact factors before video-assisted thoracoscopic resection of lung nodules / 中国介入影像与治疗学

ABSTRACT

Objective: To observe the complications and impact factors of microcoil locating of pulmonary nodules before video-assisted thoracoscopic resection (VATS). Methods: A retrospective analysis was performed on 160 patients with pulmonary nodules (160 nodules) who underwent CT guided microcoil location of pulmonary nodules before VATS. Postoperative complications were counted, and the impact factors of relative complications of microcoil location were analyzed. Results: Nodules were successfully located in all 160 cases. Pneumothorax and pulmonary hemorrhage were found in 26 and 37 cases, respectively, while no air embolism occurred. All patients underwent VATS on the next day, and no microcoil displacement was found during operation. Univariate analysis showed that the patient's position (P=0.04), the distance from nodule to pleura (P=0.03) and the times of puncture (P<0.01) were related to pneumothorax, while the distance from nodule to pleura (P=0.03) was related to pulmonary hemorrhage. Multivariate analysis showed that the patient's position, the distance from nodule to pleura and the times of puncture were all independent risk factors for pneumothorax (all P<0.05), and the distance from nodule to pleura was the independent risk factor for pulmonary hemorrhage after locating of microcoil (P=0.01). Conclusion: Pneumothorax and pulmonary hemorrhage might occur after microcoil location of lung nodules before VATS. Pneumothorax related to the distance from nodule to pleura, patient's position and the times of puncture, while pulmonary hemorrhage only related to the distance from nodule to pleura.
