CT-gesteuerte Lungenherdmarkierung vor minimal-invasiver Operation
2001
Video-assisted thoracoscopic surgery (VATS) is an established method for resection of suspicious pulmonary lesions. However, there are problems to detect small subpleural lesions. A procedure for localization of such lesions will be demonstrated. Since may 2000 our experience includes 5 patients (4m, 1f) suffering from solitary pulmonary lesions. In preparation of VATS a CT-guided marking was carried out using both a lasermarker system as well as a special marker system for lung lesions. All 5 procedures were successful. With the laser system the pulmonary nodule was exactly marked and the special wire was placed without any complications. Consequently, the pulmonary nodule was fixed. During video-assisted wedge resection the nodule can be tracted outside. Operating time was reduced in comparison to time consuming search of unmarked lesions. The combined application of CT-guided marking,transthoracic fixation of pulmonary nodule and VATS is recommended preoperatively. It should apply in lesions,which are located subpleural and thoracoscopically not visible.
