ABSTRACT
PURPOSE: To evaluate the usefulness and complications of ultrasonography (US)-guided vacuum assisted biopsy (VAB) for the removal of benign breast lesions, and the short- and long-term changes after VAB as shown on follow-up US. MATERIALS AND METHODS: From January 2007 to May 2008, 110 sonographically benign lesions in 62 patients were sampled via US-guided VAB. We prospectively evaluated the sonographic findings 1 week and 6 months after VAB in all patients to determine the presence of residual tumors, hematomas and scarring. We evaluated the prevalence of hematoma, pain, skin dimpling, fibrotic scarring and residual tumors after US-guided VAB, and determined if correlation existed between complications, size of the lesions and lesion pathology. RESULTS: The age of the patients was 15-65 years, with a mean age of 36.5 years. The pathologic diagnoses were fibroadenomas (41.8%, n = 46), fibrocystic changes (30.9%, n = 34), fibroadenomatoid hyperplasias (13.6%, n = 15), fibroadenomatoid mastopathies (6.3%, n = 7), adenoses (3.6%, n = 4), hamartomas (1.8%, n = 2) and phyllodes tumors (1.8%, n = 2). Complications 1 week after the US-guided VAB included hematomas (n = 39, 35.4%), pain (n = 23, 20.9%), fibrotic scars (n = 26, 23.68%), residual tumors (n = 4, 3.6%) and skin dimplings (n = 4, 3.6%). Complications 6 months after the US-guided VAB included hematomas (n = 12, 10.9%), pain (n = 3 2.7%), fibrotic scars (n = 14, 12.7%), and residual tumors (n = 17, 15.4%). Residual tumor after US-guided VAB existed in association with 15.2% of fibroadenomas (7/46), 14.7% of fibrocystic changes (5/34), 13.3% of fibroadenomatoid hyperplasias (2/15), 25% of adenoses (1/4), and 100% of phyllodes tumors (2/2). CONCLUSION: US-guided VAB is an effective procedure for removal of benign breast lesion. Periodic follow up studies at 1week and 6months after the VAB are useful to assess Post-VAB complications.
