The Normal Adult Human Liver Biopsy: A Quantitative Reference Standard

table 4. Parallelism of Structural Profiles Within Portal Tracts

Parallelism
Bile ducts to hepatic arteries	92% ± 8%
Hepatic arteries to bile ducts	96% ± 5%
Portal veins to bile ducts	95% ± 6%
Portal veins to hepatic arteries	93% ± 8%
Bile ducts to portal veins	72% ± 17%
Hepatic arteries to portal veins	72% ± 19%
Characteristics
Portal tracts without portal veins	38% ± 19%
Portal tracts without bile ducts	7% ± 6%
Portal tracts without hepatic arteries	9% ± 7%

NOTE. The simultaneous occurrence of interlobular bile ducts, hepatic arteries, and portal veins within portal tracts is given on a percent basis, as defined in the text. The converse also is shown, namely the percent of portal tracts lacking portal veins, interlobular bile ducts, or hepatic arteries.
