Brain aneurysm Arteriovenous Racemotic

Brain aneurysm arteriovenous racemosum (a. cerebri arteriovenosum racemosum) is a pathological dilatation of the blood vessels of the brain, in which arteries and veins are connected without intermediate capillaries. This leads to impaired blood flow and increased pressure in the venous system.

This type of aneurysm is called racemotic because of the characteristic grape-shaped bundle of tortuous and dilated vessels. It can occur in any area of ​​the brain, most often in the middle cerebral artery.

The main symptoms include severe headaches, nausea, vomiting, visual and hearing impairment, and seizures. Diagnosed using computed tomography or magnetic resonance imaging.

The main treatment method is surgery - clipping the aneurysm. Endovascular embolization of blood vessels is also used. If left untreated, severe complications, including death, can occur.

The prognosis depends on the location, size of the aneurysm and timeliness of medical care. Following the doctor's recommendations and regular examinations help prevent the development of dangerous complications.



Title: "Cerebral aneurysm: arteriovenous rascemarazny aneurysm"

Introduction An aneurysm is an expansion of a vessel in the circulatory system, which can lead to rupture and bleeding. This type of aneurysm is called a rastsema, in which the vascular crescent or “rastsel” expands towards the cerebral cortex. The development of the disease is often preceded by low blood pressure and physical inactivity. Arterial aneurysm is also known as progressive aneurysmal disease. This is due to the fact that they continue to slowly grow in size and most often lead to rupture, which provokes bleeding in the brain. Research has established that the disease develops due to improper internal lining of blood vessels. Let's get acquainted with more detailed information.

Arteries of the brain - sources of blood flow The brain has a complex vascular system that provides it with blood supply. Vessels are divided into arteries and veins. The arteries, namely the cerebral cortex, cerebellum, forebrain, medulla oblongata and spinal cord, are supplied exclusively with arterial blood. The main function of arterioles is to oxygenate the blood and deliver nutrients and gases to all parts of the body. Blood enters the vessels through the subclan opening. In some cases, it flows backward due to circulatory problems. The blood returning back to the arteriole is intensively saturated with oxygen, due to which it returns to the vessels and tissues of the body. It is important to note that the return of blood to the arterial system can affect the process of oxygen saturation. Oxygenated blood is supplied to the brain structures when it is already depleted. If insufficient oxygen is returned to it, tissue cells will begin to experience oxygen deficiency, which will cause their damage. It should be mentally noted that in addition to the arterial system of the brain, a person has a venous system corresponding to this system. When comparing blood flow within arterioles and veins, significant differences in blood composition can be found. Thus, arreteli have a low level of plasma protein and a high level of hemoglobin, while the main vein contains a large amount of lymph and proteins. These details are essential in the context of a medical diagnosis. The details of the origin and course of arterial aneursms, including life-threatening issues, are discussed further. Classification of cerebral aneurysms As mentioned above, the arteriovenous spread is an expansion associated with the formation of a connecting expansion in the bend of the outflow arteries of the head, as a result of which the sources in them are covered by additional communication paths. According to the place of origin of RASC, many types are distinguished. The most significant of them are listed below. Rascel of Willis - located on the surface of the base of the brain when blood passes through the Willis; Emphysematous rash – occurs between the outer surface of the hemispheres and the condylar arteries; Recurrent thrombosis or RTC (recurrent thrombosis) - this rascel is located in the frontal areas of the brain and develops in the case of constant fluctuations in blood pressure; Supracerebral rascel - located on the descending branch of the cranial



The brain is an amazing organ with incredibly complex structure and functions. It contains hundreds of billions of neurons that form a complex network of connections that allow us to think, feel and act. However, like any other organ, the brain can be subject to various diseases, one of which is an aneurysm.

An aneurysm is
