Ultrasonography-Guided Vacuum Assisted Biopsy for Breast Lesions: Clinical Performance and Complications

Abstract

The objective of this article is to evaluate the usefulness and complications of an USG-guided vacuum assisted biopsy (USG-VAB) for the removal of benign breast lesions.From January-2016 to May-2017, 90 sonographically benign lesions in 70 patients were sampled via USG-VAB. We prospectively evaluated the sonographic findings 1 week and 6 months after VAB. We evaluated the prevalence of hematoma, pain, skin dimpling, fibrotic scarring and residual tumors after US-guided VAB, and analyzed the correlation between the complications, size and pathologic results of the lesions. The pathologic diagnoses were fibroadenomas, fibrocystic changes, fibroadenomatoidhyperplasias, adenoses, hamartomas and phyllodes tumors. The complications 1 week after the US-guided VAB included hematomas (n=32, 33.3%), pain (n=23, 25.5%), fibrotic scars (n=20, 22.2%) and skin dimplings (n=1, 1,1%). Residual tumor after US-guided VAB existed in association with 10.8% of fibroadenomas (5/46), 16.7% of fibrocystic changes (4/24), 13.3% of fibroadenomatoidhyperplasias (2/15), and 100% of phyllodes tumors (1/1). USG- VAB is the useful procedure for removal of benign breast lesion. Periodic follow up studies after the USG-VAB are necessary to evaluate the complication after the VAB.
