Abstract:
Objective The aim of this study is to evaluate the efficacy and safety of preoperative Computed Tomography (CT)-guided microcoil localization for pulmonary ground-glass opacity.Methods We performed CT-guided Microcoil localization in 30 patients with 32 pure ground glass opacities between December 2012 and September 2013.All 30 patients underwent CT-guided micmcoil localization under local anesthesia with a 21G needle percutaneous lung biopsy.All patients accepted video-assisted thoracic surgery after the localization the same day or the next day.Results We located 32 pure ground glass opacitiesin 30 patients.The mean lesion diameter was 0.94 cm,the average depth from the visceral pleura was 0.71 cm,all leisons were successfully located by microcoil,asymptomatic pneumothorax was observed in seven patients,pulmonary hematoma was observed in two patients,pain was observed in one patient,dislodgement was found in one patient during the operation.None of these cases needed surgical treatment.Pathologic diagnoses of the target leisions were as follows:adenocarcinoma in situ (n =17),adenocarcinoma(n =9),atypical hyperplasia(n =4),inflammation (n =2).After the placement of preoperative CT-guided microcoil localization for pulmonary ground-glass opacity,all the 32 pulmonary pure ground-glass opacities resection success rate was 100％.Conclusion Preoperative CT-guided microcoil localization for pulmonary pure ground-glass opacity is a safe and effective way to improve the accuracy of surgical resection.
