肺小结节术前CT引导下亚甲蓝定位的临床应用

【目的】 探讨CT引导下亚甲蓝术前定位在胸腔镜肺小结节切除的临床应用价值?【方法】 对28例患者30枚肺小结节,术前CT引导下亚甲蓝定位后行电视胸腔镜手术(VATS)肺楔形切除术?【结果】 30枚肺小结节均成功定位,定位所需时间 (22.13 ± 5.36)min?3例(10.7%)患者定位后出现少量气胸,但无需胸腔闭式引流术?本组28例患者行VATS肺楔形切除术成功率为100%,无中转开胸?VATS肺楔形切除手术时间为(17.82 ± 5.63)min,术中失血量为(20.03 ± 13.78)mL?【结论】 肺小结节CT引导下亚甲蓝术前定位是一种简单?有效和安全的定位方法,值得推广?

CT-guided Preoperative Localization for Small Solitary Pulmonary Nodules with Methylene Blue in Video-assisted Thoracic Surgery

【Objectives】 To evaluate the efficiency and safety of CT-guided preoperative localization for small solitary pulmonary nodules (SSPN) with methylene blue in video-assisted thoracic surgery (VATS). 【Methods】 Thirty SSPN in 28 patients were preoperatively localized under CT guidance and marked with methylene blue injections before VATS wedge resection. 【Results】 All the thirty SSPN were localized successfully. The mean localization time was (22.13 ± 5.36)min. Only 3 patients (10.7%) had mild pneumothorax, but no one needed chest tube drainage. All the nodules were successfully removed by VATS, and no one was converted to open thoracotomy. The time of VATS wedge resection was (17.82 ± 5.63)min, and the blood loss volume was (20.03 ± 13.78)mL. 【Conclusions】 Methylene blue preoperative localization of SSPN under CT guidance is a simple, effective and safe method and is worth promoting.
