Abstract:
Objective To prospectively evaluate the efficacy and safety of Computed Tomography (CT)-guided microcoil localization for pulmonary small solid nodules and ground-glass opacity prior to thoracoscopic resection.And to investigate the indication for CT-guided microcoil localization for small solid pulmonary nodules and ground-glass opacity.Methods From December 2012 to February 2014,85 enrolled patients with pulmonary solid nodules and ground-glass opacity underwent CT guided microcoil localization prior to video assisted thoracoscopic surgery.The procedures of localization were performed by trailing method or routine method under CT guided percutaneous pneumocentesis.For Trailing method,the microcoil was placed with the distal part coiled adjacent to the lesion and the proximal end coiled beyond the parietal pleura.By routine method,the entire microcoil was injected adjacent to the lesion.Results CT-guided microcoil placements were successful in all ninety-one lesions,including 15 solid nodules,15 mixed ground glass opacity,and 61 pure ground glass opacity,with an average diameter of 8.75mm(5-26 mm).The Complication rate of the localization procedure was 23.5％ (20/91),with 13 cases of asymptomatic pneumothorax,and 7 cases of pulmonary hematoma.None patient required surgical intervention,nor severe Complication occurred.All patients underwent video assisted thorascopic surgery on the same day or the next few days after microcoil localization.VATS removal of the pulmonary lesions was successful in all patients.However,two of 91 microcoils were found displaced during VATS resection.The success rate of microcoil marking VATS resection for pulmonary small solid nodules and ground-glass opacity was 97.8％.Microcoil marking was required for 84.6 percent of all the resected lesions.Conclusion Preoperatively CT-guided microcoil localization for pulmonary small solid nodules and ground-glass opacity is a feasible safe and effective marking technique for video assisted thoracoscopic resection.The indication for microcoil localization in our study meet the requirement of VATS resection.
