目的测定肝内扩张胆管位置,设计恰当的穿刺途径,提高经皮肝穿胆道造影术(PTC)成功率。方法对9例恶性阻塞性黄疸患者采用经皮肝穿靶胆管定位方法穿刺。结果穿刺次数为l～4次,共17次,每例平均1.9次,成功率为52.9%。结论经皮肝穿胆道造影术靶胆管定位穿刺可提高穿刺成功率,减少肝脏损伤等并发症。
Objective To determine the location of intrahepatic dilatation of bile duct and design appropriate puncture pathways to improve the success rate of percutaneous transhepatic cholangiography (PTC). Methods Nine patients with malignant obstructive jaundice were treated with percutaneous transhepatic bile duct approach. Results The number of punctures was l ~ 4 times, a total of 17 times, each case an average of 1.9 times, the success rate was 52.9%. Conclusion Percutaneous transhepatic cholangiography guided bile duct positioning puncture can improve the puncture success rate and reduce complications such as liver injury.
