目的探讨超声造影在甲状腺良性肿瘤激光消融中的应用价值。方法 50例患者共79个甲状腺良性肿瘤,入组标准为肿瘤长径大于2cm小于4cm、体积1-15ml,且患者甲状腺功能正常。随机分为两组,A组为超声造影组,消融后采用超声造影评价肿瘤灭活情况,共30例患者49个结节;B组为常规超声组,消融后采用常规超声评价肿瘤是否完全灭活,共20例患者30个结节。结果术后随访6-12个月,A组术后无复发;B组复发4个,复发率13.3%,P<0.05。结论应用CEUS评价甲状腺良性肿瘤激光消融准确、简便,可有效减少肿瘤原位复发。
Objective To investigate the value of contrast-enhanced ultrasound in the laser ablation of benign thyroid tumors. Methods Totally 79 thyroid benign tumors in 50 patients were enrolled in this study. The standard of the patients was as follows: the major diameter of the tumor was larger than 2cm and smaller than 4cm; the volume was 1-15ml; and the thyroid function was normal. A group was divided into two groups at random. After the ablation, the tumor inactivation was evaluated by contrast-enhanced ultrasound, and there were 49 nodules in 30 patients. The conventional ultrasound group in group B was used to evaluate whether the tumor was completely destroyed after ablation Live, a total of 20 patients 30 nodules. Results The patients were followed up for 6-12 months. No recurrence was found in group A, 4 in group B, and the recurrence rate was 13.3% (P <0.05). Conclusion The CEUS evaluation of thyroid benign tumor laser ablation accurate and simple, can effectively reduce the tumor recurrence in situ.
