Anonymous users2024-02-12A pulmonary arteriovenous aneurysm is a congenital pulmonary vascular malformation, varicose blood vessel or cavernous hemangioma that is not contagious. Pulmonary artery blood flows directly into the pulmonary veins without alveoli, and the pulmonary arteries and veins communicate directly to form a short circuit. All symptomatic and localized patients require surgery**.
Pulmonary arteriovenous tumors are not infectious diseases and cannot be transmitted to others. Infectious disease refers to the transmission of a disease by a source of infection to a vulnerable infected person by carrying a pathogen. Pulmonary arteriovenous aneurysm is a non-communicable disease, there is no source of infection, and of course there is no such thing as contagion.
In arteriovenous aneurysm, a tumor-like lesion occurs when a blood vessel swells to a certain extent. Tumors are actually different from other tumors in that they mainly dilate blood vessels. If the degree of dilatation does not exceed twice the diameter of the blood vessel, this condition can only be considered tumor-like dilation.
The degree of dilation is more than twice the diameter of the blood vessel, which is called a tumor. Because it occurs in blood vessels, it is called an arteriovenous aneurysm. If it occurs in the arteries and veins of the lungs, it is called a pulmonary arteriovenous aneurysm, so this condition is easy to understand.
Of course, the specific cause may be vasculitis or a more specific disease. For example, Marfan syndrome or Kawasaki disease can cause blood vessels to dilate.
Embolization**, the most commonly used embolization material is stainless steel coil, followed by balloons, tissue adhesives, absorbable gelatin sponges, silicone plastic pellets, etc. Once the embolic material has entered the blood vessels, it cannot be removed, so it must be properly placed before it is placed. The advantage of this method is that it does not open the chest and preserves more lung tissue.
The disadvantage is that the embolization should be below the x-ray. The embolization is inaccurate or detached, leading to embolic complications, easy to cause pneumonia, high cost, **will not be completely**. Single-lung arteriovenous fistulas can be wedged to remove the lesion or lobe segmentectomy, which in principle preserves as much normal lung tissue as possible.
But pay attention to the blood in the lungs**. There will be a variety of variations in pulmonary arteriovenous fistula malformation, pathological sections can find a variety of variations of malformed blood vessels, and some diseased lung tissues are difficult to find in smaller surgeries, and it is easy to ** after surgery.

Anonymous users2024-02-11Pulmonary arteriovenous aneurysms are not contagious, because there is a scientific basis, and I think pulmonary arteriovenous aneurysms are a cardiovascular disease, and this disease is very difficult, so we must protect our bodies.

Anonymous users2024-02-10Not contagious. Pulmonary arteriovenous aneurysm is a relatively serious tumor disease, which is very harmful to the body, affecting the body's metabolism, and then it is also likely to be fatal.

Anonymous users2024-02-09Non-contagious, it refers to congenital pulmonary vascular malformations, blood vessels will enlarge, and spongy ducts will appear, which is called pulmonary arteriovenous tumors.
1 Distribution law outside the organ: basic symmetrical distribution on the left and right The arteries of the trunk trunk are divided into parietal branches and visceral branches Arteries are often accompanied by veins and nerves to form nerve bundles There is an arterial trunk in each part of the human body Most arterial truncus is located on the flexor, deep and hidden parts of the body Arteries often reach the organs in which they are distributed at the shortest distance The form of arterial distribution is related to the morphology of the organ The caliber of the artery is sometimes not completely determined by the size of the organ it supplies blood 2 The distribution law in the organ: The artery of the solid organ often penetrates through its depression Organ arteries with lobulated structures enter hollow or tubular organs from the "gate", and the arteries are distributed in a divergent, transverse, or total row pattern. >>>More
Vascular malformation, also known as hemangioma, is an abnormal dilatation of capillaries, veins, arteries or lymphatic vessels with the tissue structure and biological characteristics of normal endothelial cells, which is further divided into arteriovenous malformations, venous malformations, capillary malformations and small lymphatic malformations, and the latter three are collectively referred to as vascular malformations. There is no abnormal proliferation of vascular endothelial cells, surrounded by normal reticular connective tissue, and smooth muscle tissue is visible inside. The vast majority (found after birth) grow slowly with age and never regress. >>>More
Hemangiomas include vein aneurysms, aneurysms. All of them are caused by the thin walls of local blood vessels, where the blood pressure is outward and the blood vessel walls are outward. >>>More
1. Do more exercises to clench your fists, if your hands are swollen badly (I have been like this for a while after surgery), don't dare to move, but move more, the blood flow will naturally go away. >>>More
