Ground-glass nodules and CT-guided placement of platinum coils Nódulos em vidro fosco e marcadores espirais de platina guiados por TC

Various centers perform the excision of these small growing nodules using video-assisted thoracoscopic surgery (VATS) in order to minimize postoperative morbidity, as well as to remove as small a volume of lung tissue as possible. Small nodules are often visible with the thoracoscope if they lie within 5 mm of the visceral pleural surface; however, if they are located deeper in the lung, palpation is required in order to locate them for excision. A previous study found that, in a series of 92 consecutive patients undergoing VATS, 50 (54%) required conversion to thoracotomy.
