Why does this kind of critical condition make doctors "take a breath"?

In our bodies, except for hair and nails, dense blood vessels are distributed in other places.

Blood vessels are the transportation channel of blood. The blood vessels that undertake the hemorrhage of the heart to pump the heart are called the arteries. The blood vessels that undertake the blood of the long -term back to the heart of the heart are called veins.

Aortic is the most important artery

The direct connecting the heart of the aorta is the main road of the arteries and the source of the arteries branch at all levels. It is shaped like a question mark and consists of three parts: the aortic, aortic arch, and the aorta.

The aorta is the part where the arteries continue to go up from the heart. The well -known coronary artery is divided from this section to play the role of nourishing the heart itself;

The aortic arch is a curve formed by the vascular folding after the aorta is promoted. This can be divided into dry arms, carotid artery, etc. to supply brain and upper limbs;

The aorta reduction is an arteries that extends downward after the curve. On the way, there are branches of intestinal membrane upper, lower artery, renal artery, etc. to nourish the corresponding organs. As shown in the figure:

The aorta is a tubular structure. Its vascular wall consists of three layers of endometrium, intermediate elastic layer, and outer membrane. It is the thickest elastic layer in the middle and is rich in elastic fiber. It is the basis for blood vessel contraction and expansion.

Generally speaking, the three -layer structure of the aorta wall is closely linked and there is no gap.

However, in some cases, the active artificial wall may also be split in half (the most often appear in the middle and outer side of the elastic layer). At this time, the blood will flow into the blood vessel wall under the action of pressure. Active artery clay layer.

What are the symptoms of the aortic selane?

Because the blood vessels are torn, 90%of the people will have severe pain that will not bear when the aortic clading occurs, and it will produce a sense of dying that is about to be torn. This pain is often unforgettable for life.

The blood vessel wall is split, and the blood cannot supply the corresponding organs normally, which may cause ischemia and abnormalities.

If cerebral ischemia occurs, symptoms such as paralysis, memory loss, dark eyes, and skewed tongue may occur; if kidney ischemia occurs, there will be no urine; if the abdominal organs and lower limb ischemia may occur, abdominal pain may still occur. , His lower limbs, cold, black, etc.

The aortic lower layer is not treated for a long time. From the acute stage to a chronic stage, most of the pellets will be evolved into mezzanine aneurysm. If the increase in tumor body may compress the nerves, leading to some dysfunction, such as compressing the throat and returning nerves. It may cause hoarseness and symptoms such as swallowing difficulties.

In short, the aortic sandwich is a very dangerous disease, and it can even be said that it is a critical illness in critical illness. Because the mezzanine may rupture and bleed at any time, it can quickly endanger life. "Take a bite of cold air".

Which dangerous factors can easily lead to aortic lower layers

Intersection

The occurrence of aortic claying often needs to meet three conditions: endometrium has cracks, sufficient blood pressure, and not tough enough vascular itself.

First of all, the endometrium can enter the blood vessel wall; second, if there is enough blood pressure, the blood has sufficient impact, and the blood vessel wall can be forced to split and form a mezzanine; How far can be split.

Therefore, the risk factors that lead to aortic lower layers are roughly related to these three aspects, such as: vascular inflammation, trauma, abnormal vascular development, hypertension, arteriosclerosis, etc.

In addition, the patients with Ma Fan's syndrome, due to the fragile vascular texture, is also very prone to the aortic clay.

Moreover, the destructiveness of Matan's syndrome is often greater. The blood can easily "split to the end" by blood. Due to the rapid destruction, the pain is sometimes not so heavy.

In our country, the aortic semiration is earlier earlier than that internationally, and the average age is about 50 years old.

So remind people of this age, especially pay attention to the symptoms of suspicious severe chest pain, abdominal pain and other symptoms, be sure to go to the hospital immediately. If you find it earlier, maybe everything is too late!
