title: CT-guided needle localization of lung nodules for thoracoscopic resection.
abstract: We used CT to guide positioning of hookwires within 19 lung nodules in order to localize them prior to thoracoscopic surgery. Both Hawkins III and Kopans-type needles with internal hookwires were employed. Nodule diameter ranged between 0.7 and 4 cm (mean 1.7 cm), and depth from the site of entry of the needle into the pleural surface ranged from 0.5 to 8 cm. Needles were advanced using a technique identical to that for CT-guided biopsy, and localization proved successful in 18 of 19 cases. During surgery, dislodgement of the guidewire occurred in 5 cases, probably due to traction manoeuvers on it. In all these cases the hook of the wire had been opened within the nodule. No dislodgement occurred in patients in whom the needle had been advanced beyond the nodule and the hook allowed to open in the pulmonary parenchyma deep to it. Severe complications did not occur: there was moderate pleuritic pain in 16 cases and asymptomatic pneumothorax in 13 patients. Computer-tomography-guided needle localization of lung nodules is a safe and relatively easy procedure that allows thoracoscopic surgery of lesions which otherwise might be impossible to locate and resect.
