Aexperimentalresearch was performed in radiology center of Bach Mai hospital to evaluate the initial efficacy in the removal of benign breast lesions by vacuum-assisted biopsy

SUMMARY

Subjects and methods: There is a prospective intervention study in 21 female patients with 31 benign breast lesions with needle aspiration vacuumassisted biopsy under ultrasound guidance from Jan 2018 to Jun 2018.

Results: The mean age is 37.5 years old.The 20-30 years old group is most common (19.3%). The average size of the lesions measuring on ultrasound is 11.7mm. The average number of samples is 10.8 with the average time of cutting is 12 minutes. The most common abnormality pathology is breast fibroadenoma (54.8%). Fibrocystic breast disease accounts for 25.8% of all lesions, which is second highest rate. The main complications after biopsy are pain and hematoma. There is a proportional correlation between the size of the lesions and other factors such as the amount of anesthetics used, the volume of the hematoma after the biopsy, the time of wound removal and the size of the biopsy needle. There is a inverse correlation between the distance from the lesion to the nipple and post-biopsy pain. The distance from the lesion to the skin surface is inversely proportional to the size of the post-biopsy hematoma.

Conclusion: Vacuum-assisted breast biopsy is an effective and safe method for removal benign breast lesions. This method is also highly aesthetic. The anapathology results based on this method are reliable, especially for small lesions.

Key words: Vacuum-asisted biopsy, mammotome, benign breast lesions.
