Another purpose was to present 3D models of the liver segments and terminal branches of the portal triad
and hepatic vein in a PDF file that can assist in learning and training with anatomy and clinical surgery.
Focusing on portal triads
, RIO appeared first in the hepatic arterial branches, irrigating the PVP capillaries (Figure 3(h)), and then entered adjacent PV branches through tiny anastomoses (Figures 3(i) and 3(j)).
Stained cells were counted in 5 microscopic fields (x100) per slide in tumor, peritumoral tissue defined as portal triad
, as well as central vein area.
(a) Control group's representative image showing a normal portal triad
. (b) Supplemented group.
The analysis in the portal triad
for these groups indicated that the staining level was distributed as follows: in C2-3, 8% slight level, 57% moderate level and 35% intense level.
The basic functional unit of the liver is the hepatic lobule, which consists of portal triads
(hepatic arteriole, portal venule, bile duct, lymphatics and branch of the vagal nerve) at the periphery that surround a central vein (Fig.
One-way analysis of variance (ANOVA) was used to analyze a significant difference in mean number of portal triads
and specimen length utilizing STATA software, College Station, tX.
Injured bile ducts surrounded by a dense infiltrate of mononuclear cells, most of which are lymphocytes, these florid, asymmetric destructive lesions of interlobular bile ducts are irregularly scattered throughout the portal triads
and often seen only on large surgical biopsies of the liver in which adequate representation of small bile ducts occurs; inflammation is confined to the portal trials (Hirschfield, 2011).
The classic findings on liver biopsy of patients with PBC is asymmetric destruction of the bile ducts within the portal triads
. (2) Patients are further classified into stages (i.e., stage one through four) based on the degree of destruction and the number of bile ducts involved.
Isolated resection of the caudate lobe consisted of four major steps: mobilization of the lobe, outflow control by dividing the short hepatic veins behind the lobe, inflow control by dividing the portal triads
to the lobe, and division of the hepatic parenchyma between the caudate lobe and the main liver.
Additionally, because the nodules cannot be visualized on routine H&E or trichrome staining, a special reticulin stain must be performed to show the nodules clustered around the portal triads
without fibrosis or collagen deposition, in contrast to alcoholic cirrhosis.
