Cerebral arteriovenous malformation

Cerebral arteriovenous malformation is the most common type of cerebrovascular malformation and is located in the superficial or deep part of the brain. Malformed blood vessels are made up of arteries and veins. Some include aneurysms and venous aneurysms. Cerebral arteriovenous malformations have blood-supplying arteries and drainage veins. They are various in size and shape. More common in the frontal and parietal lobe, others such as the temporal lobe, occipital lobe, ventricle, thalamus, cerebellum and brain stem also occur. According to the size of the lesion: a diameter of less than 2.5 cm is small, 2.5 to 5 cm is medium, 5 to 7.5 cm is large, and> 7.5 cm is extra large. Such arteriovenous malformations can also occur in the dura. Often manifested as epilepsy and spontaneous cerebral hemorrhage, may have paralysis of limbs, some cases have increased intracranial pressure, similar to brain tumors, large cerebral arteriovenous malformations, and sometimes cause symptoms of intracranial stasis, auscultation of the cranial orbital sometimes Hear vascular noise.
