The intra-hepatic biliary system in cirrhósis.

The authors study 14 cirrhotic livers by means of post-mortem cholangiography and vinyl casts. They analyze the radiographs according to thorough criterions, described in the text, and come to the conclusion that intrahepatic biliary ducts in cirrhotic livers present serious alterations, represented by distorted ducts with focal stenoses, nodular impressions, wall irregularities, increase of the number of obtuse angles and poor peripheral filling, which confer a disharmonic aspect to the intra-hepatic biliary ducts of these organs. Furthermore, they show that livers with post-necrotic cirrhosis present bile ducts much more seriously damaged than those with Laennec's cirrhosis. The paper was submitted to statistical analysis and allows objective conclusions.

Post-mortem aeroportography.

The authors suggest a new methodology for the study of the intrahepatic portal system, using atmospheric air as a contrast medium. They used 48 livers of normal and pathological corpses, obtaining post-mortem cholangiographies and vinyl molds. Comparing the images obtained with literature data and with the vinyl molds, the authors conclude that the method is accurate, presenting furthermore many advantages with regard to contrasts generally used, such as low cost, easy performance, possibility repeating the radiographs as many times as necessary, and the possibility of simultaneous obtaining contrasts of other intra-hepatic systems by use of other radio-opaque contrast media in another system, as for example the biliary or the arterial system.
