Objective To explore and analyze the related influencing factors for common intraoperative complications during CT-guided percutaneous radiofrequency ablation of pulmonary tumor. Methods We retrospectively analyzed the clinical data of the patients who underwent CT-guided percutaneous radiofrequency ablation of pulmonary tumor in our hospital from December 2018 to December 2019, and analyzed the influencing factors for complications. Results A total of 106 patients were enrolled. There were 58 (54.7%) males and 48 (45.3%) females aged 46-81 (68.05±8.05) years. All patients successfully completed the operation. The operation time was 47.67±16.47 min, and the hospital stay time was 2.45±1.35 d. The main intraoperative complications were pneumothorax (16.0%, 17/106) and intrapulmonary hemorrhage (22.6%, 24/106). Univariate analysis showed that the number of pleural punctures had an impact on the occurrence of pneumothorax (P=0.00). The length of the puncture path (P=0.00), ablation range (P=0.03) and ablation time (P=0.00) had an impact on the occurrence of intrapulmonary hemorrhage. Multivariate logistic regression analysis showed that the size of the lesion (OR=17.85, 95%CI 3.41-93.28, P=0.00) and the number of pleural punctures (OR=0.02, 95%CI 0.00-0.11, P=0.00) were independent influencing factors for the occurrence of pneumothorax. The length of the puncture path (OR=15.76, 95%CI 5.34-46.57, P=0.00) was the independent influencing factor for the occurrence of intrapulmonary hemorrhage. Conclusion Percutaneous radiofrequency ablation of pulmonary tumor is safe and with a high success rate, but intraoperative complications are affected by many factors, so the surgeons should be proficient in operating skills to avoid complications.
