肝脏恶性肿瘤局部消融治疗后即刻超声造影必要性探讨

目的探讨肝脏恶性肿瘤局部消融治疗后即刻是否有必要进行超声造影。方法对行射频或微波消融治疗的92个肝脏恶性肿瘤病灶分别于治疗前后进行超声造影，19个病灶进行了术后穿刺活检。结果术前92个病灶超声造影均表现为早期动脉相高增强，术后14个病灶表现为早期动脉相局部不规则高增强，活检病理证实肿瘤残留；5个病灶外周环状增强，活检病理未见肿瘤存活。结论肝脏恶性肿瘤局部消融术后即刻超声造影有助于指导进一步治疗。

Importance of Immediate Contrast-enhanced Sonography to Evaluate Therapeutic Responses of Ablation Treatment for Malignant Liver Tumors

Objective To investigate the necessity to evaluate the therapeutic response of ablation therapy using contrast-enhanced sonography immediately. Methods Ninety-two malignant liver lesions were examined with contrast-enhanced sonography before and after ablation therapy. Percutaneous puncture biopsy was done in 19 lesions after ablation therapy. Results Hyper-enhancement was seen in all 92 lesions before ablation. After ablation, irregular hyper-enhancement was shown in 14 lesions with alive tumor cells confirmed by biopsy. Hyper-enhancement around lesions was shown in 5 lesions without alive tumor cellss in pathology. Conclusions In order to guide further treatment, it is necessary to immediately evaluate the ablation therapeutic response of malignant liver tumors via contrast-enhanced sonography.
