Abstract
The techniques for superselective catheterization of hepatic artery are described. The catheters have five major configurations in various sizes: (1) simple curve, (2) reverse curve, (3) double curve, (4) modified double curve, and (5) hepatic and splenic curves. Since the celiac artery may be directed caudad, horizontally, or cephalad, the techniques vary accordingly. The basic approach of the system described is to tailor the catheter to fit the vascular anatomy. These various techniques have produced a 95% success rate in the hepatic artery catheterization of 1,000 patients.
