CT引导下弯针穿刺乙醇消融术治疗微小肝癌

目的 探讨可控弯曲穿刺针在微小肝癌CT引导下无水乙醇消融术中的价值。方法 采用可控弯针穿刺时，仅需将外套管针穿至病灶边缘，换插可弯曲细针，根据针尾的指示，合理调整针尖位置，对准病灶方向即可顺利穿入病灶。结果 25例微小肝癌患者共29个小病灶采用弯针穿刺，24个病灶一次穿刺成功，22个病灶一次乙醇消融达到完全凝固性坏死。结论 采用可控弯曲穿刺针有助于提高穿刺成功率，乙醇消融治疗微小肝癌疗效显著。

CT-guided percutaneous ethanol injection in macro-liver neoplasms with flexible puncture needle

Objective To evaluate the clincal value of CT -guided percutaneous ethanol injection in macro-liver neoplasms using flexible puncture needle. Methods When the flexible puncture needle was applicated, the straight trocar was first used to reach the adjacent area of lesions, and then the thin flexible puncture needle was pushed into the lesions through the trocar by making the curve direction of the flexible puncture needle towards the lesions according to the maker in needle tail. Results There were 29 small lesions in 25 cases. Twenty-four lesions were punctured successfully only once. Twenty-two lesions were completely necrosis after ethanol injection one time. Conclusion It is helpful to improve successful ratio using the flexible puncture needle. Curative effect of ethanol abalation in macro-liver neoplasms is satisfactory.
