The utility of simultaneous CT-guided localization for multiple pulmonary nodules using microcoil before video-assisted thoracic surgery

Abstract Background To evaluate the feasibility and safety of microcoil in simultaneous localization for multiple pulmonary nodules before video-assisted thoracic surgery (VATS). Methods Twenty-eight consecutive patients (26 two-nodule, 2 three-nodule; 58 total; Group A) underwent CT-guided VATS using microcoil. Successful targeting, localization, were defined as implantation at target site on CT image which was obtained immediately after marking procedure, visualization nodule location, complete resection with adequate margin, respectively. Meanwhile, clinical characteristics, procedure-related variables complications group A also assessed compared those a control (221 single-localization procedures 221 patients; B). Results Similar rates successful observed B (96.6% vs. 98.2%; 91.4% 91.0%; 100% 99.1%). Although rate overall (including localized pneumothorax intrapulmonary hemorrhage) bit higher than that (32.8% 30.8%, p = 0.771), only minor subjects two groups no need further treatment. In addition, duration significantly longer single (24 ± 7.5 vs.13 6 min, < 0.001). Conclusions clinically feasible safe acceptable increase procedure time. Compared nodule, localizations prone to hemorrhage. However, statistically significant differences between groups.
