| Abstract | ||||
| Arteriovenous malformation (AVM) is defined as a fast-flow vascular anomaly that shunts blood from arteries directly to veins without any intervening capillary bed. Intracranial AVM is the most common etiology of intracranial hemorrhage in the younger population, predisposing them to long-term morbidity and mortality. The origin of AVM remains unclear and is still under investigation. The most-quoted standard grading system used in ascertaining the outcome and management of intracranial AVM is the one described by Speltzer and Martin (S-M), which is based on size of AVM, its venous drainage and eloquence of brain adjacent to the malformation. The current gold standard for diagnosis and follow-up of cerebral AVMs is digital subtraction angiography (DSA). It characterizes angio-architectural features of AVM conclusively and gives hemodynamic information which is an integral part of planning treatment. However, the downside of DSA is that it’s invasive, expensive, time consuming and exposes the patient and personnel to significant amount of radiation. | ||||
