Abstract

Purpose. To evaluate the advisability of use by interventional radiologists of the ABBI system for stereotactic biopsy in the diagnosis of mammographically detected nonpalpable breast lesions considered suspicious for cancer. Material and methods. Breast biopsy with the ABBI cannula, available in various diameters, was offered to 61 patients who gave their informed consent and was performed in 36. Reasons for exclusion were insufficient thickness of the compressed breast (37.5%), the lesion site (50%) and the failure to detect the lesion with stereotactic mammography (12.5%). The procedure was carried out under local anesthesia in an outpatient setting. Fifteen nodules, 15 groups of microcalcifications and 6 nodules with calcifications were excised. The diameter of the ABBI cannula used was 20 mm in 32 cases and 15 mm in four cases. Results. A definitive histological diagnosis was obtained in all cases, with the identification of 20 neoplasms (56%) and 16 benign lesions (44%). The lesions margins were involved in 14 cases of malignancy. All the patients with a diagnosis of malignancy underwent surgery. No residual tumor was found in five cases. The mean diameter of the lesions removed was 11-12 mm. The only complications were two late hematomas which were drained by simple percutaneous aspiration. The procedure was well tolerated by all patients except one who experienced a vagal attack due to emotional stress. Conclusions. Stereotactic breast biopsy with an ABBI surgical cannula can be carried out autonomously by interventional radiologists, safely and with diagnostic accuracy.
