【摘要】 传统的PTCD和PTPC方法有许多缺点。其技术难度较大,成功率不高,并发症较多。用粗针直接穿刺肝脏是产生并发症的主要原因之一。而PTCD程序与PTC程序的脱节,以及PTPC不能用细针试穿,是产生并发症的另一个原因,本文设计研制了一种多用套管穿刺针,并在27例病人中试用,临床结果显示,使用该针明显改进了PTCD和PTPC方法。改进后的PTCD和PTPC方法具有容易操作,肝组织损伤小,成功率高,并发症少等优点。该针结构简单,设计合理,还适用于某些体内深部脓肿、积液及囊肿的穿刺置管引流。更多还原

【Abstract】 There are some defects in the traditional technique of percutaneous trans-hepatic cholangio drainage (PTCD) and precutaneous transhepatic portalcatheterization (PTPC). Both of them are difficult to perform. Their successrates are not so high, however, their complications are rather more.The directpuncture of the liver with a thick needle is one of the main reasons of thecomplication and that the procedure of PTCD is separated from the procedureof percutaneous transhepatic cholangiography (PTC) is another one. In this paper, we have designed a new pattern of needle for puncture andit in 27 patients. The clinic results have shown that it obviously improvedthe technique of PTCD and PTPC. The improved method of PTCD and PTFC are easy to perform. The dama-ges of liver are less than before, their success rates are higher and the ratesof their complication are lower. This needle is also suitable to some drainage of abscess, liquid accumula- tion, cyst in deep place of body.更多还原
