Pancreatic blood supply

Any organ or tissue in the human body is enriched by the necessary nutrientsWith the help of blood supply. However, different vessels and arteries come to each separate organ. Where does the arterial blood come from in such an indispensable organ as the pancreas?

Like any mixed secretion gland, the pancreas has a special structure of the blood supply system.

Therefore, the arterial blood flow is carried out at the expense of several arteries, such as:

1. Outer pancreatoduodenal artery branch of the gastroduodenal artery( which are common hepatic artery inflow) - feed the head of the pancreas from the front surface.
2. The lower pancreatoduodenal artery - originates from the superior mesenteric artery and supplies the posterior surface of the head of the pancreas.
3. The branches of the spleen artery - feed the blood and nutrients to the rest of the pancreas( body and tail).

have upper and lower pakreatoduodenalnyh arteries there is another distinctive feature - the connection between the blood vessels and the formation of a so front and rear portions of the arterial arc. Such arcs, connected together, are the main part for the continuous circular movement of blood in the arteries.

Arteries

Arteries and arterial arcs in the pancreas are located, both intersecting and parallel. For example, if you look at the anatomical location of the posterior arch on the head of the pancreas and the anterior one, you can make an interesting observation: the posterior is much closer to the middle than the anterior one.

In addition, there are two more specific forms of arterial arches location:

1. Rassypnoe form, characterized by a large multiple arteries that form arcs themselves;
2. The arcuate shape of the arcs, which is formed after the process of merging the two arteries.

gastro-duodenal artery

This small perfused vessel length of 20-40 mm and a diameter of 2.5-5 mm, in the vast majority of cases is the total discharge of the hepatic artery.

The artery is also located behind the department, which controls the intake of food directly into the stomach. In addition, it crosses the initial section of the intestine in a variety of ways.

Abnormal discharge of vessels

Because of the special location of the blood supply to the pancreas does not happen very often the appearance of various anomalies and pathologies. However, their occurrence and causes a keen interest of surgeons.

One of such rare and dangerous cases in which vascular damage is possible is the removal of the right hepatic from the gastroduodenal artery. What is so dangerous for man?

long as the patient does not need an operation, during which performed pancreatoduodenal resection( the only available method of treatment for cancer of the pancreatic head, preampulyarnoy of the bile duct and duodenal papilla), this anomaly it is not terrible. However, if this problem still touched the patient, then it was not an easy task to solve it.

In some literature it can be found that medicine has found the answer to this question. For example, by autoventric bypassing of the right hepatic blood vessel, which was performed until the intersection of the gastro-duodenum.

In other books such information is also abundant. There was also such an unusual case when the main hepatic blood vessel was divided into 4 turns: the right and left hepatic, gastro-duodenum, and the right gastric artery. Such situations are especially dangerous in case of damage, especially subjected to destruction - any fractional hepatic artery. Outflow of blood from the pancreas

As you know, any organ enriched with venous vessels also has veins that create an outflow of passable blood. Venous outflow in the pancreas is through the pancreatododeal veins that flow into the spleen, as well as the lower and upper mesenteric, and the left gastric vein. All together it forms one large vein - the collar vein, which then enters the liver.

Scheme of blood supply

Based on the scheme depicting the circulatory system of the pancreas, you can see that most of the veins are located in the tail. Arterial blood from these vessels must necessarily enter the circulatory system with a portal vein.
There are also cases when the above described vessels can pass the outflow of the pancreas. Such pathologies and diseases are extremely dangerous, because they are able to develop both necrosis of the pancreatic tail and pancreatitis.

In addition to this, a harmful habit like drinking alcoholic beverages can lead to a dangerous condition of the pancreas's blood supply. Why does this happen?
All because dangerous to health in general, "a tool that helps to get away from all problems", can cause necrosis of pancreatic cells. Alcohol directly affects the narrowing of smaller vessels, which because of this can not bring nutrients to the cells. In this regard, the cells are starving for lack of nutrients and die.

Among other things, alcohol, consumed in large quantities, can cause the deposition of salts in the tail of the pancreas. Even more unpleasant things are for women drinking alcohol, because all these unpleasant processes they develop more rapidly than men.
