[Percutaneous localization of pulmonary nodules with CT guidance for lung resection: use of dyes].
OBJECTIVE
The purpose of this study was to assess the benefits of computed tomography(CT)-guided marking using dyes in patients undergoing lung resection for peripheral nodules.


METHODS
Between January 1997 and August 2002, the location of small pulmonary nodules was identified with the aid of CT-guided marking in 52 patients scheduled for surgery. Dye-injection was performed in 52 patients (indigo carmine, n = 15; indocyanine green, n = 37). The average nodule size was 9.2 mm (range, 3 to 18 mm).


RESULTS
The procedure using dyes proved to be easy and safe: the dyes were easily injected near the nodules, and no serious complications ensued. Intraoperatively, indocyanine was superior to indigo carmine with respect to visualization of the dyed pleural surface.


CONCLUSIONS
The preoperative CT-guided injection of indocyanine green proved to be the most useful and safest technique for identifying peripheral pulmonary nodules in patients scheduled for thoracoscopic surgery or minimal thoracotomy.
