目的探讨彩色多普勒超声对原发性肝癌肝动脉栓塞治疗后的疗效评价。方法应用彩色多普勒超声观察32例原发性肝癌介入治疗前后的声像图改变及瘤体内血液动力学变化。结果本组病例均为高血供,介入治疗后瘤体有不同程度缩小,治疗前13例巨块型肝癌大小平均13 cm×12 cm,治疗后平均12 cm×9 cm;6例结节型肝癌术前大小6 cm×5 cm,术后平均4 cm×5 cm;TAE后肿瘤内部动脉血流变化明显,肿瘤血管完全消失11例,明显减少16例,减少5例。治疗前肿瘤内部动脉血流vmax(56±12)cm/s,治疗后肿瘤内部动脉血流vmax(25±12)cm/s,两者相比差异有统计学意义(P<0.05〉,介入后血液中AFP下降。结论彩色多普勒能有效评价肝癌介入治疗疗效。
Objective To evaluate the efficacy of color Doppler ultrasound in the treatment of primary hepatic carcinoma after hepatic artery embolization. Methods Color Doppler ultrasonography was used to observe the changes of sonography before and after interventional treatment of 32 cases of primary liver cancer. Results The patients in this group all had high blood supply. After interventional treatment, the tumors were reduced to different degrees. Before treatment, the size of 13 cases of massive liver cancer was 13 cm×12 cm in average, and the average size was 12 cm×9 cm after treatment. Six cases of nodular type were treated. The preoperative liver cancer was 6 cm×5 cm in size, and 4 cm×5 cm in average after operation. After the TAE, the blood flow of the internal arteries of the tumor changed significantly. The tumor vessels completely disappeared in 11 cases, significantly reduced in 16 cases, and decreased in 5 cases. Before treatment, the internal arterial blood flow of the tumor was vmax(56±12)cm/s. After treatment, the internal arterial blood flow of the tumor was vmax(25±12)cm/s. There was a statistically significant difference between the two (P<0.05). After the AFP decline in the blood.Conclusion Color Doppler can effectively evaluate the efficacy of interventional treatment of liver cancer.
