摘要

乳房立體定位真空抽吸術為目前乳癌診斷的主要方式之一，病患主要採側臥姿為主，經過局部麻醉後，將切片針由垂直或側位進入目標位置取出微鈣化，再將其送去病理化驗，以檢查出是否有乳癌的可能。而此檢查會有乳房厚度的限制，一般採取垂直進針，當病患乳房厚度偏薄（27 mm以下）的狀況下，則會採取側位進針模式，由於亞洲女性的乳房相對歐美女性較小，側位進針為國內執行乳房立體定位真空抽吸術之常見方式。本案例病患來院施做乳房立體定位真空抽吸術，但因為乳房較薄（壓迫厚度15 mm），且病灶位置於乳房上方，經過四個階段擺位後，最終採取坐姿並搭配側位進針採檢成功，藉由此案例提供較薄乳房，實行乳房立體定位真空抽吸術之參考。

Stereotactic vacuum‐assisted needle biopsy is one of the techniques in breast cancer diagnosis. The examination is usually performed with the patient in a prone decubitus position. After achieving local anesthesia, a biopsy needle is introduced into the microcalcifications using a vertical or a lateral approach, and multiple core samples are taken. Biopsy specimens are then sent for pathological diagnosis. Breast thickness should be considered when performing the biopsy. Generally, the procedure is usually performed using a vertical approach. However, it must switch to a lateral approach when the compression thickness is lower than 27 mm. Because Asian women have thinner breasts than European and American women on average, the lateral approach is more common in stereotactic vacuum‐assisted needle biopsy cases in Taiwan. We reported a case underwent stereotactic vacuum‐assisted needle biopsy with a breast compression thickness of 15 mm. We tried several times using different positions and eventually performed the biopsy using a lateral approach with the patient in an upright position. This case may provide an example of performing stereotactic vacuum‐assisted needle biopsy in patients with small breast.
