超声引导下经皮介入治疗单纯肝肾囊肿

目的：观察ＣＯ２与无水酒精作为囊肿固定剂的疗效，比较肝、肾囊肿经介入治疗疗效差别。２２例单纯囊肿，其中肝囊肿１４例，肾囊肿８例，采用经皮穿刺抽吸囊液后，注入固定剂ＣＯ２或无水酒精１￣３次，随访２￣２９个月。结果：２２例２２个囊肿均获得不同程度的好转，占６２．５％。肾囊肿８例均一次治疗后最大直径在随访期间内未超过２ｃｍ，明显好转率为１００％。而肝囊肿１４例中仅５例一次治疗明显好转，占３５．７％。结论

Percutaneous Interventional Treatment of Simple Hepatic or Renal Cyst under Guidance of Ultrasound

Purpose:We observed and compared the therapeutic effects of CO_2 and dehy- drated ethanol as sclerosing agent,in percutaneous interventional methods for treatment of hepatic and renal cysts,Materials and methods:Twenty-two simple cysts,14 in livers,8 in kidneys,af- ter percutaneous puncture and aspiration,we instilled CO_2 or dehydrated ethanol into the cysts once, twice or thrice with followed-up for 2 to 29 months,Results:All the 22 cysts in 22 patients were better after treatment especially of them,including 8 of 12 cases(66.7%)treated with dehydrated ethanol only once.The maximum diameters of 8 renal cysts(8/8,100%)after one treatment re- duced to less than 2cm in the follow-up,comparing with only 5 of 14 hepatic cysts(5/14,35. 7%).Conclusion:1)Pereutaneous interventional method by guidance of ultrasound is safe and ef- fective in simple hepatic or renal cyst treatment.2)CO_2 is similar to dehydrated ethanol as a scleros- ing agent.3)The therapeutic effect of simple renal cyst is better than that of hepetic cyst.
