目的 探讨立体定位导丝导向活检不能触及的乳腺病灶的价值。方法 对 2 5例不能触及的乳腺病灶行立体定位导丝导向活检 2 6处 ,对每处病灶计算出穿刺针针尖至病灶中心的距离(D) ,并直接测量出留置的导丝头端至病灶中心的距离作对照。判断标准 :优 :D≤ 2 5mm ;良 :D =2 6～ 4 9mm ;差 :D≥ 5 0mm。结果 定位优 2 0例次 ,良 5例次 ,差 1例次。穿刺针针尖至病灶中心距离的计算值与直接测量值相符。 1次性病灶切除 2 6例次 ,标本体积的中位数为 10 5cm3,检出乳腺癌 6 (6 / 2 6 )处。结论 立体定位导丝导向活检不能触及的乳腺病灶能以最小的手术范围完整切除病灶 ,定位定性效果确切 ,可避免假阴性。提高了乳腺癌的早期检出率及诊断准确性。
Objective To investigate the value of stereotactic guidewire-guided biopsy inaccessible breast lesions. Methods Twenty-five unresectable breast lesions were treated with stereotactic guidewire guided biopsy, and the distance from the needle tip to the lesion center was calculated for each lesion (D), and the guidewire end to indwelling The center of the lesion as a control. Criteria: excellent: D ≤ 2 5mm; good: D = 26 ~ 49mm; poor: D ≥ 50mm. The results were excellent in locating 20 cases, good in 5 cases and poor in 1 case. The calculated value of the distance from the tip of the lancet to the center of the lesion corresponds to the direct measurement. A single lesion was removed 26 times, with a median of 10 5 cm 3 and 6 (6/26) breast cancers. Conclusion Stereotaxic guidewire biopsy can not reach the breast lesions can be completely removed with minimal surgical range of lesions, the exact positioning qualitative effect, to avoid false-negative. Improve the early detection rate of breast cancer and diagnostic accuracy.
