Abstract
In order to simplify the technique of superselective hepatic arteriography, a new catheter named "twist catheter" was designed. This catheter is made of KIFA catheter (red), and has a twisted end about 10cm. long.
Using this catheter, superselective hepatic arteriography was tried in 98 out of 147 cases. Superselective common hepatic and proper hepatic arteriographies were successful without replacement of catheter in respectively 89 cases (90.8%) and 48 cases (49%) only by twisting the catheter. Replaced right hepatic (12 cases) and left gastric arteriographies (5 cases) were also successful in all cases.
Not only simplified twist cathcter the procedure of superselective hepatic arteriography, but also shortened the X-ray exposure time expended for angiography.
Up to now, any complications due to introduction of twist catheter were not experienced.
