    Aortic aneurysm and aortic dissection are diseases that are difficult to detect clinically in daily life, so it is usually too late for patients to go to the hospital for treatment.

    Little sister is amazing.  Another thing that is the most powerful thing about this little junior sister is her single-mindedness.  Huang Zhilei sighed.

    ¡°Looking at everyone thinking about what to do with this trap, Xie Wanying stood in front of the light board and kept studying the mr picture.

    Duan Sanbao stood behind her and watched the movie with her.

    ¡°It may be that the two of them discussed the patient case once in the afternoon and argued about what should be argued. Now watching the film, silence is golden.

    Other teachers and bosses were bombarded by the information about this patient's serious illness, and their brains were a little irritated, so they stood around and argued endlessly.

    "Coma. The MRI is definitely not accurate. If we take another picture, the dissection should have torn into the innominate artery or the left common carotid artery."

    The innominate artery and the left common carotid artery have been mentioned before. They are branches from the aortic arch and connect important cerebral blood vessels.  It can be said that if something goes wrong with these two blood vessels, the brain tissue will be deprived of blood and nutrients.  Cerebral ischemia caused the patient's consciousness disorder, and the direct clinical manifestation is that Aki's mother is now unconscious.

    How does aortic dissection cause the innominate artery and left common carotid artery to "cut off blood"?

    Here are some other characteristics of aortic dissection.  It is similar to an aortic aneurysm: it may burst like a balloon and cause massive bleeding.  A large hematoma forms and compresses nearby organs and tissues.  For example, compression of the nearby esophagus may cause dysphagia, and compression of the superior mesenteric artery may cause intestinal necrosis.

    But it is obvious that aortic dissection can widely cause various "blood cutoff" symptoms in organs other than the above-mentioned reasons.  The obvious difference between aortic dissection and aortic aneurysm is that the adventitia is not broken and the blood flows into the dissection.

    There is blood in the dissection, which will squeeze the original true lumen of the blood vessel, causing the blood flow in the true lumen to drop sharply.  The most intuitive clinical manifestation is the blood pressure difference between the patient's two limbs.  There is less blood in the true lumen of the blood vessels on the side of the extremity that is compressed by the dissection, resulting in low blood pressure measured.

    To put it more deeply, low blood pressure is definitely not a good thing. Anyone who studies medicine knows that it means that some part of the body is ischemic.

    This is indeed the case. Even if the blood seems to be not lost after running through the dissection, in fact, after this part of the blood escapes into the dissection, less blood flows into the true lumen of the blood vessel.  The dissection is a false blood vessel, not a true blood vessel. It is not connected to the main blood vessels of the organ. Blood needs to go from the true cavity to the organ for organ nutrition.  The blood that ran to the dissection slipped away and failed to reach the organs.  This will cause the blood vessel segment with dissection to "cut off blood".  As long as the main blood vessel trunks supplying blood to other organs are related to this dissection, all of them will be "blood cut off."  These organs are naturally in a state of ischemia, which is also called malperfusion and hypoperfusion in medicine.

    For example, if one or both renal arteries are involved, the patient will suffer from anuria, hematuria, and severe renal failure.

    Celiac artery involvement may lead to irreparable consequences of liver and spleen infarction.

    It affects the arteries of the lower limbs, ranging from chills to severe pain and necrosis.  This is why Axi's mother's limbs are cold.

    By "cutting off blood" to the spinal cord, symptoms may appear in the corresponding spinal cord segment, ranging from mild lumbar pain to paraplegia.

    The above-mentioned innominate artery, the left common carotid artery, was "pinched", and central nervous system symptoms appeared.
