?:definition
  • Angiographic vascular catheters designed to inject contrast media in the great vessels of the neck and/or the intracranial arteries. These catheters usually have three separate curves and variations in the distal curve are needed to seek the orifice of the appropriate vessel; their distal tip may include a taper. Thin, flexible catheters with balloon tips are used for extremely selective angiography; in some cases, microballoons that follow blood flow are used in small intracranial arteries. Cerebral angiographic vascular catheters are used in the diagnosis of both extracranial and intracranial occlusive vascular diseases.
