【2618】Bleeding
Aortic aneurysm aortic dissection is a disease that is difficult to detect in clinical practice on weekdays, so it is too late to wait for patients to visit the hospital.
The junior sister is amazing. Another thing that makes the junior sister the most amazing is her stubbornness. Huang Zhilei sighed.
Seeing that everyone was thinking about what to do with this pit, Xie Wanying stood in front of the light board and was studying the MR film.
Duan Sanbao stood behind her and watched the movie with her.
Maybe the two of them discussed a patient case in the afternoon, and they had to argue and argue once. Now they can be more silent when watching the movie.
The other teachers and bosses were bombarded by the patient's serious illness information, and their brains were somewhat stimulating, and they stood by and argued endlessly.
"I'm in a coma. This MR film is definitely not accurate. If you take a photo, this dissection should have torn the nameless artery or the left common carotid artery."
The nameless artery and the left common carotid artery have been mentioned before, which are branches emitted by the aortic arch and connect to the important cerebral blood vessel trunk. It can be said that once these two blood vessels have any problems, the brain tissue will be cut off from the blood and nourished. Cerebral hemorrhage ischemia
This caused the patient's consciousness disorder, which was directly manifested as the current mother Yaxi was unconscious.
How does the aortic dissection cause the "blood cut" of the nameless artery and the left common carotid artery?
Here we will talk about other characteristics of the aortic dissection disease. It has similarities to aortic aneurysms: it is afraid of explosions, ruptures, and bleeding. It forms a hematoma with a large balloon to compress nearby organs and tissues. For example, compressing the nearby esophagus will cause
Difficulty swallowing, compressing the superior mesenteric artery, may lead to intestinal necrosis.
But it is obvious that the aortic dissection can cause various "blood cutoff" symptoms in the organs. The significant difference between aortic dissection and aortic aneurysm is that the outer membrane is not broken and the blood runs into the dissection.
.
There is blood in the dissection, which will squeeze the original true cavity of the blood vessel, causing the blood flow in the true cavity to drop sharply. What is most intuitive in clinical practice is the difference in blood pressure on both sides of the patient's limbs. The true blood vessels on the limbs that are compressed by the dissection are true.
There is little blood in the cavity, resulting in low blood pressure.
To put it more deeply, low blood pressure is definitely not a good thing. All those who study medicine know that this means that a certain part of the body ischemia.
This is true. Even if the blood runs in the dissection, it seems that it is not lost. In fact, after this part of the blood runs to the dissection, less blood flows from the true cavity of the blood vessels. The dissection is fake, not real blood vessels, and it does not contact the main blood vessels of the organs.
The blood needs to go from the real cavity to the organ to provide nutrition for organs. The blood that runs to the dissection slips away and fails to reach the organs. This will cause the blood vessel segments that occur in the dissection to "break the blood". As long as the blood supply to other organs is mainly
If the trachea of the blood vessel is related to this section of dissection, it will all be "blood-cut". These organs are naturally in an ischemia state, which is also called poor perfusion and insufficient perfusion in medicine.
For example, if one or both renal arteries are involved, patients will suffer from severe renal failure if they have severe auricular hematuria.
The involvement of the abdominal artery may cause irrescue consequences of liver and spleen infarction.
This is why Yaxi's mother's limbs have chills at a mild rate, and is painful and necrotic at a severe rate. This is why her limbs are chills.
If the spinal cord is "cut off blood", it is possible that the corresponding spinal cord segment may have symptoms. In mild cases, lumbar pain will cause paraplegia.
