The Porta hepatis is centrally located in the middle third of the visceral surface; it has an "L" shape rotated ninety degrees to the left; it presents a transverse part, another anterior part, and they form a 90-degree angle of anterior medial sinus; the hepatic portal vein is divided here into right (A12.3.12.002) and left (A12.3.12.005) branches; the hepatic artery proper is divided into right (A12.3.12.030) and left (A12.3.12.035) branches; the common hepatic duct is formed by the union of the right hepatic (A05.8.01.062) and the left hepatic (A05.8.01.065); these branches form the first vascular division; then, on the edge of this parenchymal channel, these two "primary branches" emit seven terminal secondary branches, forming seven vascular pedicles for seven portal segments.
(2017) found: Arterial irrigation comes from the hepatic artery proper in 70 % of cases; from the hepatic artery proper and a branch of left gastric artery (A12.2.12.013) in 25 %, from the hepatic artery proper plus a branch from left gastric artery plus a branch from superior mesenteric artery (A12.2.12.053) in 3 %, and from the hepatic artery proper and a branch from superior mesenteric artery in 2 %.
The hepatic artery proper
, common hepatic duct and hepatic portal vein were blocked using three vascular clips for 60 min (Figure 1C) followed by 120-min reperfusion (Figure 1D).
Distal recanalisation and collateral flow was also seen in the hepatic artery proper
and proximal splenic artery.
Right gastric artery arising from hepatic artery proper
in 55 (78.5%) cases (Fig.
She underwent a CT scan, which revealed an incidental finding of a large saccular aneurysm involving the common hepatic artery and the hepatic artery proper
, measuring 6.2 x 7.1 x 7.5cm in maximum dimensions (Figure 1).
We studied 286 human livers (A05.8.01.001) of different ages (from fetuses to octogenarians), races and sex, using the following techniques: 150 livers were injected with colored acrylic in the hepatic portal vein (A12.3.12.001), hepatic artery proper
(A12.2.12.029), common hepatic duct (A05.8.01.061), inferior vena cava (A12.3.09.001) and through it to the hepatic veins (A12.3.09.005), were then immersed in a solution of 10 % hydrochloric acid to remove the parenchyma to study injected anatomical elements; 50 were dissected in fresh and 30 were dissected after fixing them with formalin using the knowledge that gave the acrylics; we studied 56 cases of three-dimensional tomographic reconstructions of patients randomly selected using the concepts learned through dissections.
SMA = Superior Mesenteric Artery; GDA = Gastro-duodenal artery; HAP = Hepatic Artery Proper
The common hepatic artery divides into three branchessplenic artery, left gastroduodenal artery and hepatic artery proper
. The gastroduodenalartery terminates by dividing into superior pancreatico duodenal and right gastroepiploic arteries.
It divides into hepatic artery proper
and gastroduodenal artery.
One limb of the T was the right gastric artery and the other gave off the hepatic artery proper
and continued as the gastroduodenal and pancreatico-duodenal system, as usual.
Hepatic artery proper
was found to be completely transected and the cut ends were ligated.
