超声造影在甲状腺良性结节选择介入治疗方式中的价值研究

Value study of contrast-enhanced ultrasonography in interventional therapy methods selection of thyroid benign nodules

目的探讨超声造影在甲状腺良性结节选择介入治疗方式的应用价值。方法对85个甲状腺混合性良性结节进行超声造影。结节增强范围超过自身3/5的进行射频消融治疗;增强范围不到自身3/5的结节进行无水乙醇硬化治疗。治疗后即刻或1周后再次行超声造影,评估两种治疗方法的治疗效果。结果 85个甲状腺混合性良性结节中,33个结节进行射频消融治疗,一次性治疗有效率87.9%,二次性治疗有效率12.1%;52个结节进行无水乙醇硬化治疗,一次性治疗有效率88.5%,二次性治疗有效率11.5%;两者治疗效果比较差异无统计学意义。结论超声造影对甲状腺良性结节选择合适的介入治疗方式具有决策价值。

Objective To investigate application value of contrast-enhanced ultrasonography（CEUS）in interventional therapy methods selection of thyroid benign nodules. Methods Eighty-five thyroid mixed and benign nodules were examined by CEUS. When the enhanced area exceed 3/5 of itself,radio frequency ablation（RFA）was used to treat. Percutaneous ethanol injection（PEI）was proceeded in the nodules when the enhanced area was less than 3/5 of itself. The treatment effect was evaluated by CEUS after treatment. Results In 85 thyroid mixed and benign nodules,33 nodules were treated by RFA. The one-time and twice treatment efficiency are 87.9% and 12.1%,respectively. Fifty-two nodules were treated by PEI. The one-time and twice treatment efficiency are 88.5% and 11.5%,respectively. There was no significant difference between the two interventional therapy methods. Conclusion CEUS possesses the decision value in the interventional therapy methods selection of thyroid benign nodules.
