RESUMO
Objective To compare the image guided effect between CT and Ultrasound for percutaneous catheter drainage and sclerotherapy in the treatment of hepatic cysts.Methods 26 patients with hepatic cysts underwent percutaneous catheter drainage and sclerotherapy by CT guided.87 cases underwent percutaneous catheter drainage and sclerotherapy by Ultrasound guided.Results 53 cysts underwent percutaneous puncture with 132 times by CT guided,and 5 cysts underwent sclerotherapy were failed(10.1％).231 cysts underwent percutaneous puncture with 267 times by Ultrasound guided,and 5 cysts underwent sclerotherapy were failed(2.1％).The failed rate of the two groups had statistifically significant difference(x2 =39.6875,P ＜ 0.05).Conclusion In the image guided technique for percutaneous catheter drainage and sclerotherapy in the treatment of hepatic cysts,Ultrasound had more advantages,high accuracy,real time visual,high success rate,less damage,economy and convenience than CT.
