目的 :探讨超声引导经皮经肝穿刺胆管置管引流 (PTCD)的临床应用价值。方法 :梗阻性黄疸 32例 ,在超声引导下作经皮经肝胆管置管引流 (PTCD) ;对于超声显示导管不佳或位置不易确定 ,肝外胆道显示较差者 ,再在 X线透视下作胆管造影术 (PTC)行 PTCD。结果 :超声引导经皮经肝穿刺胆管 1次性成功率达 81.3% ,2次性成功率达 93.8% ,3次性成功率达 10 0 % ;单独超声引导下行 PTCD术成功率达 87.5 % ;超声引导结合 PTC行 PTCD术成功率达 96 .9%。结论 :超声引导下经皮经肝穿刺胆管准确性高 ;PTCD术应首选超声引导 ;超声引导结合 PTC可提高 PTCD的成功率
Objective : To explore the clinical value of ultrasound-guided percutaneous transhepatic biliary tube drainage (PTCD). Methods: Thirty-two patients with obstructive jaundice underwent percutaneous transhepatic and biliary tube drainage (PTCD) under ultrasound guidance. For ultrasound, the catheter was poor or the location was not easily determined. The extrahepatic biliary tract showed poorer results and under fluoroscopy Perform PTCD for PTCD. Results: The ultrasound-guided percutaneous transhepatic bile ducts had a one-time success rate of 81.3%, a secondary success rate of 93.8%, and a three-time success rate of 100%. The success rate of ultrasound-guided PTCD alone was 87.5%. The success rate of ultrasound-guided combined PTC PTCD was 96.9%. Conclusion: Ultrasound-guided percutaneous transhepatic bile ducts have high accuracy; Ultrasound-guided ultrasound is the best choice for PTCD; Ultrasound-guided PTC can improve the success rate of PTCD.
