为使PTC这项重要诊断技术在无电视监视或B超导向的医院都能开展和降低并发症,作者对设备和穿刺方法作了改进。一、采用5～6~#肾囊封闭针,在X线荧光屏下进行。二、以肝脏与肝下肠管在荧光屏上影象对比的移行线作肝下缘的标记。穿刺针在标记线上方3～4cm以上区域内穿行。三、穿刺是由右腋下第7肋间移至第9或10肋间,针尖对向从第12胸椎上缘移至剑突(预置铅块标记)。使穿刺针始终在肝内,从而避免了
In order to enable PTC, an important diagnostic technology, to develop and reduce complications in hospitals without TV surveillance or B-guided ultrasound, the author has improved the equipment and puncture methods. First, the use of 5 ~ 6 ~ # Kidney capsule closure needle, under X-ray screen. Second, the liver and liver intestine in the contrast on the screen image of the transitional line for the lower edge of the liver marker. The puncture needle passes through the area 3 to 4 cm above the marking line. Third, the puncture is moved from the right underarm 7th intercostal to the 9th or 10th intercostal space, and the needle point is moved from the upper edge of the 12th thoracic vertebra to the xiphoid process (preset lead mark). Keep the puncture needle in the liver and avoid it
