目的探讨乳腺X线立体定位侧斜位X轴入路钢丝置入的应用。方法三家医院2005年5月~2007年3月对102例(105个病变)行乳腺X线立体定位下金属钢丝置入。常规坐位操作69例,另33例因常规坐位定位失败或位置特殊行侧斜位入路定位。结果与常规坐位相比,侧斜位定位不适发生率低[12%(4/33)vs35%(24/69),χ2=5.756,P=0.016],血管迷走神经反应发生率低[3%(1/33)vs22%(15/69),χ2=5.908,P=0.015],顺利设定靶点成功率高[88%(29/33)vs43%(30/69),χ2=18.048,P=0.000],一次锚定准确率高[94%(31/33)vs45%(31/69),χ2=22.496,P=0.000],定位成功率高[91%(30/33)vs23%(16/69),χ2=41.349,P=0.000]。病变完整切除率差异无显著性[97%(32/33)vs87%(60/69),χ2=1.525,P=0.217]。结论侧斜位X轴入路乳腺X线立体定位细针定位活检术对特殊部位不可触及的乳腺病变是一种有效的定位方法。
Objective To investigate the application of stenting of X-axis mastography with oblique X-axis mammography. Methods From March 2005 to March 2007, 102 patients (105 lesions) underwent mammography stereotactic metal wire insertion in three hospitals. Conventional sitting operation in 69 cases, and the other 33 cases due to the conventional seat positioning failed or the location of special line side oblique positioning. Results Compared with the normal sitting position, the incidence of lateral oblique dislocation was low [12% (4/33) vs 35% (24/69), χ2 = 5.756, P = 0.016] (29/33) vs43% (30/69), χ2 = 18.048, P (P <0.05), P = 0.015] = 0.000]. The accuracy of primary anchoring was high [94% (31/33) vs45% (31/69), χ2 = 22.496, P = 0.000] 16/69), χ2 = 41.349, P = 0.000]. The complete resection rate of lesions was not significantly different [97% (32/33) vs87% (60/69), χ2 = 1.525, P = 0.217]. Conclusion Side oblique X-axis breast X-ray positron emission fine needle positioning biopsy is an effective method to locate the inaccessible breast lesions of special parts.
