摘　　要：目的 探讨外置激光导航系统配合模拟定位CT(CT-Sim)在经皮穿刺活检中的应用价值。方法 回顾性分析该院2019年12月至2020年12月经皮穿刺活检术女性患者42例,年龄31~77岁,其中淋巴结穿刺21例,盆腔占位穿刺17例,盆腔囊肿穿刺引流4例,拟穿刺病变部位直径(最长径)0.69~15.47 cm。使用LAP外置激光导航系统精确定位到体表穿刺点后,使用飞利浦Big Bore定位CT扫描,确定穿刺针位置、角度无误后,进行穿刺活检,记录手术时间和平均辐射剂量。结果 42例妇科恶性肿瘤患者(其中包括7例行多点穿刺)经此方法穿刺,均一次定位准确,其中17例盆腔占位穿刺平均手术时间(22.00±7.46)min, 14例淋巴结单点穿刺平均手术时间(20.00±4.66)min;7例淋巴结两点穿刺平均手术时间(30.86±4.74)min;4例盆腔淋巴囊肿穿刺引流平均手术时间(26.50±6.45)min。平均CT剂量指数(CTDI)为(35.95±4.17)mGy。结论 利用外置激光导航系统配合CT-Sim,提高了穿刺成功率,缩短了穿刺手术时间和减少了患者的辐射剂量,可实现精准、快捷、安全的经皮穿刺活检。Objective To explore the application value of external laser navigation system coordinated simulated localization CT(CT-Sim) in percutaneous puncture biopsy.Methods The retrospective analysis was made on 42 female patients with percutaneous puncture biopsy in this hospital from December 2019 to December 2020,aged 31-77 years old.Among them, 21 cases were the lymph node puncture, 17 cases were the pelvic space occupying puncture, 4 cases were the pelvic cyst puncture drainage, and the diameter of the lesions to be punctured(the longest diameter) was 0.69-15.47 cm.After the LAP external laser navigation system was used to precisely locate the puncture point on the body surface, Philips Big Bore was used to locate the CT scan.After confirming that the position and angle of the puncture needle were corrected, the puncture biopsy was carried out, and the intraoperative time and average radiation dose were recorded.Results Forty-two patients with gynecological malignant tumors(including 7 cases of multi-point puncture) were punctured by this method, and the location was accurate at once.The average operation time in 17 cases of pelvic space occupying puncture was(22.00±7.46) min, and the average time in 14 cases of lymph node single point puncture was(20.00±4.66)min;the average time of lymph node two-point puncture in 7 cases was(30.86±4.74) min;the average time of puncture and drainage for 4 cases of pelvic lymphocyst was(26.50±6.45) min.The mean CT dose index(CTDI) was(35.95±4.17) mGy.Conclusion The external laser navigation system coordinated CT-Sim increases the puncture success rate, reduces the puncture operation time and the patient′s radiation dose, and achieves accurate, fast and safe percutaneous puncture biopsy.
