目的 提高超声介入对肝肿瘤整体灭活效果。方法 对81例125个瘤体经超声引导下注射无水乙醇加碘化油(4∶1),4～6次后复查CT和彩超,对瘤体内碘化油缺如或彩超可检测到动静脉血流区域内,再次注射至整个瘤体碘化油完全充填,CDFI检测不到动静脉血流信号。结果 125个肿瘤瘤体内注射无水乙醇加碘化油治疗,经CT检查,整个瘤体充填良好率为122/125(97.6％)。结论 无水乙醇加碘化油瘤体内注射,经CT检查能准确反映瘤体内注射后的状况,此方法优于传统的经皮瘤体内无水乙醇注射治疗,也是血管法介入与间质法介入的相互结合,为单个肿瘤的整体灭活提供了可靠的治疗方法。
Objective To improve the effect of ultrasound intervention on the overall inactivation of liver tumors. Methods Eighty-one patients (125 tumors) were injected ultrasound-guided ethanol plus iodized oil (4:1). After 4 or 6 times, CT and color Doppler ultrasonography were performed. The absence of iodized oil in the tumor or color Doppler ultrasonography could be detected. In the region of venous blood flow, iodized oil was again injected into the entire tumor and was completely filled. The arteriovenous blood flow signal was not detected on CDFI. Results 125 tumors were injected with ethanol and iodized oil in vivo. After CT examination, the overall tumor filling rate was 122/125 (97.6%). Conclusion Intratumoral injection of absolute ethanol plus iodide oil tumor can accurately reflect the status after intratumoral injection by CT examination. This method is superior to traditional ethanol injection in the treatment of intratumoral neoplasia. It is also involved in vascular intervention and interstitial intervention. The combination of them provides a reliable treatment for the overall inactivation of a single tumor.
