| Sumario: | An Arteriovenous Venous Malformation (AVM) is best described as a twisted mass of arterial and venous blood vessels that shunt blood from the arterial side into the venous side of the circulation, bypassing the capillary system, and are congenital lesions that develop between the fourth to eighth weeks of the foetal stage. Symptoms depend on the size and the localisation of the AVM, but in the majority of cases the haemorrhage is the most frequent symptom. AVMs can be small focal lesions or large lesions occupying almost an entire hemisphere. The vessels may leak a small amount of blood into the subarachnoid space of the brain (of all subarachnoid haemorrhages, 10% are caused by AVMs) as they (AVMs) have a higher tendency to bleed in younger patient than in older patients. |
