Abstract
Approval for this study was obtained from our institutional ethics committee, and written informed consent was obtained from each patient prior to the procedure. Patients were admitted to the hospital the day before RF ablation treatment. Preablation imaging workup included mammography, an unenhanced and a contrast-enhanced US 11)12), and MRI of the breast.
Contrast-enhanced US using Sonazoid® with a median microbubble diameter of 2–3 μm was done for detection of breast tumor lesion and extensive intraductal component.
The skin entry site of electrode that allowed path of maximum tumor diameter plane was chosen. The device induces an ablation sphere of 3–4 cm in diameter. Because the maximum size of the target tumors was 2.0 cm in diameter, the ablation protocol was planned with the aim to destroy the visible tumor mass plus at least a 0.5-cm safety margin around the tumor. Five percent glucose solution was injected into the retromammary space to avoid burns of the major pectoral muscle. The skin just above the tumor was cooled with an ice pack.
