Radiotracer localization of nonpalpable pulmonary nodules: A single-center experience

Abstract Objective Multiple localization techniques to facilitate intraoperative identification of small or non-solid pulmonary nodules have been developed. Radiotracer localization using technetium-labeled macroaggregated albumin has been our preferred localization method since 2009. We report our experience, including technical pitfalls and modifications, of our initial 77 patients who underwent this technique. Methods All patients undergoing preoperative radiotracer localization were identified from a prospective database. Medical records were retrospectively reviewed for patient demographics, nodule characteristics, procedural details, pathological data and outcomes. Results Seventy-seven patients underwent localization of 79 pulmonary nodules. Radiotracer localization had an overall success rate of 95%; however, two patients required a 2 nd localization procedure on the same day. Most failures occurred in nodules that were 5 days) in 5 patients. Conclusions Radiotracer localization is a simple and effective technique for intraoperative identification of small pulmonary nodules.
