Precision Breast Conserving Surgery With Guidance.

Local anesthesia was induced by using 1% lidocaine before wire location. The wire (localization set, PAJUNK) was placed in the superior, inferior, lateral and interior edge of the tumor through a 20-gauge needle using US guidance one day before BCS, respectively. Then, the patient underwent an immediate supine contrast enhanced CT (Philips Brilliance iCT) scan of the breast. The radiologist performed 3D reconstruction of CT images prior to surgery. Finally, the surgical procedures were performed by experienced breast surgeons combing 3D reconstruction of CT images and wire localizations one day after the localization.
