“…The shape of porta and various structures entering and exiting through PH were also recorded to study the pattern of variations. The most constant feature was the location of portal vein situated posterior to the artery and the duct which confirms with other researchers [10,11]. Majority of the previous similar studies have focused on branching pattern of vessels or biliary structure and variations in it [12][13][14][15].…”

Background: Hepatic surgery requires comprehensive knowledge of structures passing through porta hepatis. This fact prompted us to undertake the study of porta hepatis (PH). Our aim was to find out the dimensions, shape of porta hepatis and the numerical variations of structures passing through it. Material and Methods: This study was carried out on 25 adult cadaveric formalin preserved human liver. The porta hepatis was identified and its transverse diameter, maximum anteroposterior diameter, various parts of liver contributing in its formation and total circumference were measured using Digital Sliding Vernier Caliper, thread and scale. Number of arteries, veins and ducts passing through it were observed. Observations and Results: The mean transverse diameter, anteroposterior diameter and total circumference of porta hepatis was 3.80 ± 1.03 cm, 1.79 ± 0.43 cm and 13.61 ± 1.92 cm respectively. Maximum contribution to the circumference of PH was made by caudate process (18.8%) and minimum by fossa for gall bladder (13.1%). 8 specimen showed presence of2 arteries, 1 vein and 1 duct at porta hepatis. Maximum number of arteries, veins and ducts passing through PH were 5, 3 and 3 respectively in one specimen each. In most of the cases the shape of porta hepatis was triangular. Conclusion: The dimensions and shape of porta hepatis; arrangement and number of structures at it is highly variable and hence its knowledge can be of great importance to hepato-billiary surgeons.

“…Scanty information is available regarding the dimensions of PH, contribution of various parts of liver towards the formation of porta hepatis and overall shape of porta. The authors came across study conducted by Sapna et al [10] the findings of which were of similar pattern. Table 5 shows the details of comparison.…”

“…As shown in ►Table 4, our findings correlates with other studies. 3,4 PV showed bifurcation in 72% of specimen which was highest followed by single vein in 26% and maximum number of veins was four which was seen in 2% of specimen (►Fig. 2).…”

“…Our finding correlates with similar observations, single duct was observed in 79.7 and 76% of liver specimens, respectively. 3,4 Anatomical and radiological studies have shown the presence of accessory hepatic ducts at different levels of the biliary tree and also observed the absence of right and left hepatic ducts. [16][17][18][19] Because of these anatomic variations, it becomes very much important to have knowledge about these hepatic duct variations of accessory hepatic ducts and also about their position, especially during laparoscopic cholecystectomies, as incidence of bile duct injuries is as twice as high when compared with open cholecystectomies.…”

Background and Aim Porta hepatis (PH) of the liver acts as a gateway for exit and entry of important structures like portal vein, hepatic artery, and hepatic duct. Having knowledge of variations about the dimensions and structures at PH becomes important to avoid complications during surgical and radiological interventions. Our study aims to observe the dimensions of PH and also the number, arrangement, and variations of structures passing through PH. Materials and Methods Fifty adult cadaveric human livers which were preserved in formalin were studied. Transverse diameter, anteroposterior diameter, and circumference of PH were measured using vernier calipers, measuring scale, and thread. PH was carefully dissected to study the number, arrangement, and combination of arteries, veins, and ducts at PH. Results The mean transverse diameter, anteroposterior diameter, and total circumference of PH was 3.17 ± 0.50, 1.68 ± 0.36, and 10.46 ± 1.415 cm, respectively. Eighteen specimens showed presence of two arteries, two veins, and one duct at PH. Maximum number of arteries, veins, and ducts passing through PH were 5, 4, and 1, respectively. The ducts were anterior, arteries in the middle, and veins were posterior in PH of all the livers. Conclusion The variations observed in our study will be of great importance to anatomists, surgeons, and radiologists.

The article discusses the variability of the linear dimensions of the portal vein depending on gender and age. In modern foreign and Russian literature, there is no uniform information about the variant portal vein anatomy. Data on the extreme forms and on the range of anatomical differences in the portal vein vary considerably. All this requires the need for a more detailed study of the morphometric characteristics of the portal vein branch. Computed tomography, in contrast to dissection on a corpse, allows an in vivo study of various morphometric characteristics of the portal vein.The aim of the study is to identify patterns of variability in the linear dimensions of the portal vein in persons of different sex and age.Material and methods. The study material consisted of multispiral computed tomography images of the abdominal cavity with contrast enhancement taken in 100 patients. The study included results of 56 men and 44 women, divided into 4 age groups: 1) first mature age, 2) second mature age, 3) the elderly, 4) the senile. The length of the portal vein was measured between the angle formed at the junction of the superior mesenteric and splenic veins and the angle formed by the branches of the portal vein at the hepatic hilum. The diameter of the vessel was measured at the midpoint of the distance between the proximal and distal points.Results. The length of the portal vein in the general sample was 66.45±8.49 mm, and its diameter was 11.84±1.93 mm. In women, the length of the portal vein was 64.37±6.6 mm, and its diameter was 11.33±1.83 mm, respectively. In men, both the length and diameter of the black vein were significantly greater than in women and constituted 68.09±9.4 mm and 12.24±1.91 mm, respectively. No statistically significant correlation of the studied parameters with age was detected.
