Visualization of the cystic artery after injection of Pancreozymin

In 84 patients selective angiography of the common hepatic artery before and after injection Pancreozymin was performed. The results prove that: 1. Pancreozymin produces visualization of the cystic artery and its branches and of the gall-bladder wall in the majority of these normal gall-bladders that are not visualized during angiography without Pancreozymin. 2. Pancreozymin improves visualization of many normal and pathological gall-bladders seen only faintly on angiography without Pancreozymin. 3. In a patient with an angiographically normal liver the non-visualization of the branches of the cystic artery or of the gall-bladder wall after injection of Pancreozymin is a reliable sign of organic gall-bladder disease, or of a collapsed gall-bladder seen sometimes in patients with bile duct or pancreatic tumour.
