Is venous malformation serious, is arteriovenous malformation serious

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.

It is more harmful to the human body, and it should be found that it should seek medical attention in time and treat the symptoms of the disease.

Common symptoms include headache, intracranial bruit, hemorrhage, and epilepsy.

**Before vascular malformation, it is necessary to make statistics according to the individual's onset location, type, depth and age of hemangioma, and then according to different physical conditions and conditions, surgery**, or radiation**, or cryosurgery**, or laser irradiation and other methods**. It is important to have a detailed physical examination before you can take different measures for different situations.

Cerebrovascular malformations are an important cause of spontaneous intracranial hemorrhage in young adults. Cerebrovascular malformations are harmful. First of all, after the short circuit of the arteries and veins, due to the low resistance of the fistula, the blood flow is lost from the fistula, which is called "stealing blood" in medicine, so that the normal brain tissue can not get enough blood**, ischemia and malnutrition occur.

Secondly, the artery and the vein are directly connected, and the pressure of the vein is increased, as a result, after the blood flow is nourished through the brain tissue, it cannot flow smoothly into the vein, resulting in blood stasis in the brain tissue, which will also cause the actual blood flow of the brain tissue to decline, and the brain tissue is undernourished. What's more, sometimes due to the high blood flow and pressure in the vein after the fistula, it can also cause the venous blood flow to reflux. Because the walls of the veins are very thin, it is very easy to cause blood vessels to rupture and bleed.

Finally, deformities.

Venous malformations, cardiovascular diseases, mainly manifested by mucosal or submucosal small vessel abnormalities, severe valvular heart disease, chronic renal failure, gastrointestinal radiotherapy, liver disease, collagenous vascular disease. Surgery can be done after a definitive diagnosis**. Suggestions:

For large-scale malformations of cerebral veins, under the current medical technology, there is no better way to do it except for the Gamma Knife** and the more thorough surgery**. You can go to a professional hospital in Shanghai for consultation.

Hemangiomas are congenital benign tumors or vascular malformations that are formed by the proliferation of angioblasts during the embryonic period, and are commonly found in the infants at birth or shortly after birth. The residual embryonic angioblasts, active endothelioid germ, invade adjacent tissues to form endothelial cords, which are connected to the remaining blood vessels after catheterization to form hemangiomas, and the intratumoral blood vessels are self-contained and not connected to the surrounding blood vessels. Hemangiomas can occur throughout the body, with oral and maxillofacial hemangiomas accounting for 60% of total hemangiomas, followed by the trunk (25%) and extremities (15%).

Most of them occur on the face**, subcutaneous tissues, oral mucosa, such as the tongue, lips, floor of the mouth, etc., and a few occur in the jaw or deep tissues.

Arteriovenous malformations can lead to the appearance of so many symptoms, and there will be harm, so, some people want to know, is arteriovenous malformations serious? In fact, although the incidence of arteriovenous malformation is relatively low, it is still a relatively serious disease, complex arteriovenous malformation is known as the "cancer" in vascular malformation, which is very tricky and has a poor prognosis, so there is often uncontrollable heavy bleeding, which leads to life-threatening patients.

Arteriovenous malformation is a cranoid hemangioma in morphology, which is less common than other types of vascular lesions, and its symptoms are relatively insignificant, so it is easy to be confused with other symptoms and cause misdiagnosis. When the malformed arteries pulsate abnormally, they pull on the nerve tissue, causing neuropathic pain.

When the tumor develops to a certain area, it may squeeze and compress the surrounding normal tissues and organs, resulting in organ dysfunction. For example, arteriovenous malformations under the scalp of infants develop rapidly and may cause epilepsy, glaucoma, etc. In addition, patients may also have local tissue ischemia, necrosis, ulcers, long-term non-healing, amputation in severe cases, disability, or heart failure due to long-term hemodynamic abnormalities.

In short, if arteriovenous malformations are not detected early**, they can be life-threatening, so it is necessary to pay attention.

If cerebrovascular malformations are to be detected early, it is necessary to understand its symptoms. Especially for the baby, if it is not detected in time at birth or in the period after that, the condition will become more and more serious, and it will be more difficult to carry out. Therefore, parents should know what kind of symptoms this disease has.

So, what are the symptoms of arteriovenous malformations? In fact, erect artery malformations may cause appearance deformities, compression of important tissues and organs, and functional impairment.

First, patients with arteriovenous malformations may have a purplish-red lump under the skin, while in patients with darker lumps, the lump may not be of an unusual color. If the location is superficial, the deformed flexion and discing of the blood vessels can be seen in the rock. In addition, because of the presence of arteriovenous malformations, abnormal fluctuations in the lesion site can be felt and felt by palpation.

Symptoms such as pain, ulcers, or recurrent bleeding may also occur locally. In addition, most of the arteriovenous malformations are warmer than the surrounding normal tissue.

If the disease continues to develop, there may be other hazards, such as the possibility of heart failure, which may lead to the patient's life. Therefore, it is best to detect this disease as early as possible to minimize the harm.

First of all, arteriovenous malformations are usually asymptomatic in the early stage, especially from birth to adolescence, and the symptoms of venous malformations are not obvious, only some patients will have changes in appearance, and they can feel ** fever when touched by hand, and the disease will not continue to develop for a long time. Secondly, after puberty, the color of ** will gradually deepen, pulsation and tremor can be felt on palpation, and once the blood vessel ruptures, it will cause bleeding, spontaneous necrosis, chronic ulceration and other symptoms. In particular, patients with cerebral arteriovenous malformations are prone to subarachnoid hemorrhage, intracerebral hemorrhage, vomiting, consciousness impairment and other phenomena, which can continue to worsen after physical labor or when emotional changes are drastic.

In addition, in the case of severe arteriovenous malformation, due to the abnormal dynamics of long-term blood flow, it can cause hypoobstructive heart failure, if the location of the malformation is in the stomach and duodenum, then it will cause gastrointestinal bleeding, and the patient may repeatedly have chronic anemia, severe acute gastrointestinal bleeding, episodic hematemesis and tarry stool and other symptoms during the onset of the disease, and even can lead to hemorrhagic shock, which is life-threatening. In addition, patients with cerebral artery malformations may have manifestations of progressive neurological dysfunction, such as movement disorders, sensory impairments, and even cerebral edema and cerebral atrophy.

All in all, the clinical manifestations of arteriovenous malformations will vary according to the location of the malformation, but no matter what kind of arteriovenous malformations are mainly bleeding symptoms, in case of large amount of bleeding, it is easy to cause hemorrhagic shock, which is a threat to life.
