目的探讨超声造影在治疗特殊部位肝癌中的价值。方法回顾特殊部位肝癌瘤体158个,术前行超声造影明确肿瘤浸润范围,根据治疗方法分为联合治疗组和微波消融组,在术后1个月评价术后消融效果并观察有无重大并发症。结果超声造影显示的肿瘤范围大于常规超声显示的范围,联合治疗组完全消融率为91.0%,微波消融组完全消融率为73.9%,术后均无重大并发症出现。结论超声造影可清晰显示肿瘤浸润范围,对肿瘤的疗效评价有一定的帮助。
Objective To investigate the value of contrast-enhanced ultrasound in the treatment of liver cancer with special sites. Methods A total of 158 patients with hepatocellular carcinoma at a specific site were retrospectively studied. The extent of tumor infiltration was identified by ultrasonography preoperatively. The patients were divided into the combination therapy group and the microwave ablation group according to the method of treatment. The postoperative ablation effect was evaluated one month after surgery and the presence or absence of major complications disease. Results The scope of contrast-enhanced ultrasound was larger than that of conventional ultrasound. The complete ablation rate was 91.0% in the combined treatment group and 73.9% in the microwave ablation group. No major complications occurred after operation. Conclusion Contrast-enhanced ultrasound can clearly show the extent of tumor infiltration, which is helpful to the evaluation of tumor efficacy.
