Abstract
Neuroangiography (NA) is an integral investigation in the management of patients with
neurovascular diseases. NA is basically used for diagnosis, but in many instances,
it may be followed up with treatment in the same sitting. Indications for diagnostic
NA range from extracranial diseases (vertebra-basilar insufficiency from subclavian
steal, extracranial carotid stenosis, cavernous-carotid fistula, neck trauma, epistaxis,
etc.) to intracranial diseases (nontraumatic subarachnoid hemorrhage, cerebral aneurysms,
cerebral arteriovenous malformations, cerebral vasospasm, acute stroke, etc.). A sound
understanding of the principles of appropriate periprocedural care and anatomy, catheter
technique, and basic disease pathology are vital for the test to be diagnostic. This
pictorial review illustrates normal neurovascular anatomy along with an approach to
analyze a spectrum of neurovascular pathologies and also explains a step-wise checklist
for appropriate preprocedural assessment, technique of procedure, and postprocedural
care of the patient. Basic knowledge on how to interpret these images and principles
on how to perform it is important.
