CT-guided preoperative localization of nonpalpable pulmonary lesions with a specifically designed device: evaluation of safety and efficacy.

OBJECTIVE

This study aimed to evaluate the percutaneous preoperative localization of lung masses suspected to be nonpalpable with a wedge-shaped wire (Somatex® Lung Marker System).

METHODS

Patients underwent CT-guided lung mass localization with the Somatex® Lung Marker System prior to resection of pulmonary lesions by video-assisted thoracoscopy. The characteristics of the lung masses, complication profiles, histological analysis, and surgical success were reviewed.

RESULTS

Forty lung masses were percutaneously localized preoperatively in 38 patients. Eight patients did not have malignancies. Major complications were not observed. All lung masses were fully resected after preoperative localization.

CONCLUSION

The findings support the feasibility and safety of the Somatex® Lung Marker System for the preoperative localization of lung lesions.
