title: Combined use of preoperative methylene blue dye and microcoil localization facilitates thoracoscopic wedge resection of indeterminate pulmonary nodules in children.
abstract: The ability to biopsy indeterminate pulmonary lesions in children has evolved with advances in minimal access surgery. Recent advances in preoperative localization including image-guided dye injection or wire implantation have expanded the types of lesions that are accessible via minimal access surgery. We present a case of a 13-year-old boy who underwent preoperative localization using both methylene blue dye and microcoil labeling, and a subsequent thoracoscopic pulmonary wedge resection under the same anesthesia. The combined use of both dye and microcoil localization provides the advantage of superior intraoperative visualization of the lesion and the ability to use fluoroscopy to confirm the presence of the nodule in the surgical specimen. We recommend this technique for the biopsy of indeterminate pulmonary lesions that would not otherwise be accessible via a minimally invasive approach.
