Intracranial Aneurysms and Arteriovenous Malformations : ROLE OF DIAGNOSTIC AND INTERVENTIONAL RADIOLOGY

Cerebral aneurysms and arteriovenous malformations (AVMs) are two major causes of hemorrhagic cerebrovascular diseases, Intra-arterial cerebral angiography is always the definitive diagnostic test in cerebral aneurysm however high resolution CT & CTA can discover small cerebral aneurysms that conventional angiography fails to reveal, also MRI & MRA are very useful in diagnosis of intracranial aneurysms. On the other hand, Cerebral angiography is the method of choice for the diagnosis of cerebral AVMs while advanced post processing techniques of 3D CTA and MRA studies can be used to highlight the feeding artery, the nidus and the draining veins. Cerebral aneurysms can be treated by surgical clipping or endovascular coiling with detachable coils, while treatment options of cerebral AVMs include endovascular embolization, radiosurgery and microscopic surgery. This book provides the basic and advanced information about intracranial aneurysms & arteriovenous malformations, how to diagnose and how to treat by endovascular technique, for the radiologists and interventionists.
