Natural course of the arteriovenous malformations of the brain

Arteriovenous cerebral malformations represent congenital malformations. Considering the anatomical characteristics of the cerebral angiomas and their localization, in a great number of cases they demand a combined therapeutic approach - surgery,. embolization and radiotherapy. Besides the constant progress of technology, 5% of all cerebral angiomas can not be completely excluded from the circulation. Therefore, the need to understand their natural course became a necessity. Our results point to the fact that they are vascular malformations of a considerably more benign clinical course than the aneurysms. Our clinical model points to an annual risk of hemorrhage which is 3.3% with total mortality of 5.3%, especially if the size of the angioma is 2.5-5 cm, localized in the motor zone of the brain, with combined type of vein drainage and arterial supply from the vertebrobasilary confluence. Epilepsy caused by the cerebral angioma is in 26.7% refractory to medicamentous therapy and in 25% (every 4th patient) will have hemorrhage with an annual risk of 0.14%.

Phonocephalography and pulsatile tinnitus in a surface cerebral angioma

Phonocephalography is a simple, passive non-invasive diagnostic technique in tinnitus and cerebral angiology.Pulsatile tinnitus may occur in hypertension, haemodynamic disorders, or extracranial and intracranial vascular abnormalities. It is ignored by otologists and neurologists. Phonocephalography is the amplification and recording of sounds from the surface and cavities of the head. In this case report, the technique of phonocephalography was used to records these sounds and the tinnitus in a case of surgace cerebral angioma.

Possible significance of juvenile oral venous angioma as marker of intracerebral vascular lesion

✓ This 10-year-old child suffered a hemorrhage into the right parietal lobe, the result of a ruptured arteriovenous angioma. From birth, the boy had a venous angioma of the mucous membrane of the cheek, lower lip, and hypoglossal area on the right side. The coexistence of these two vascular defects is most unusual, and venous angioma in early life may suggest the presence of cerebral angioma.
