改良向右两弯型导管在肝动脉插管中的应用

Application of Modified RH Type Catheters in Hepatic Arterial Catheterization

本文详细介绍了二种改良向右两弯型导管（ＲＨ１、ＲＨ２）的形状及在肝动脉插管中的应用。其中ＲＨ１型导管由于兼有盘曲型及向右两弯型导管的优点，其肝动脉插管的成功率明显提高至９６％，且可用于其他腹腔内脏动脉的超选择插管，是一种多功能导管，可作为常用导管；而ＲＨ２型导管，由于增加了短臂的长度使得成襻较困难，可是对肝动脉插管的成功率仍很高（９７％）以及本文介绍的新成襻方法，该导管可作为备用导管。

The configurations and application skills of the two modified RH type catheters(RH1 and RH2)were described in details. The RH1 type catheter has the advantages of both the Disk-like type and RH type catheter, and the success rate of RH1 type catheter in hepatic arterial catheterization is improved(96%)and also in other visceral arterial catheterization. So it is a multipurpose catheter and should be in common use. While for RH2 type catheter, although the prolonged short arm made the loop formation a little more difficult, but the success rate of hepatic arterial catheterization is high(97%), so it can be used as an alternate catheter.
