Use of the Patent Blue and Air in the Preoperative Marking of Impalpable Breast Lesions

Abstract

Objective: The goal of this study is to analyze the applicability of the patent blue dye and air in the preoperative marking of impalpable mammarylesions with indication of surgical resection.Materials and Methods: A prospective cohort study was performed. We selected 49 patients with detection of impalpable lesions on a breastmammography or breast ultrasonography. The patients received the dye injection as close to their surgery time as possible. The criteria analyzedincluded: 1) complete marking and identification of the lesion; 2) complete removal of the lesion; 3) in cases of malignant lesions, presence of freemargins for successful surgery; 4) occurrence of allergic events; 5) necessity of reoperation; and 6) difficulty in locating lesions.Results: All lesions were marked, and they were successfully excised. In cases of malignancy, free margins were obtained in 100% of the cases. Therewere no allergic events or reoperations. Only 8.9% of the lesions were difficult to locate.Conclusion: The marking with patent blue and air is an effective alternative for the labeling of impalpable breast lesions, and it has satisfactorysurgical oncology results. All lesions were resected, 91.1% of them were performed with no difficulties, and free margins were obtained in 100% ofcases of malignancy.
