Electronic radiography in stereotaxic thrombosis of intracranial aneurysms and catheter embolization of cerebral arteriovenous malformations.

Abstract

An electronic radiographic technique which utilizes a television fluoroscopic system coupled with a disc recorder is described. Images from this system can be combined with live fluoroscopic images, allowing rapid and accurate catheterization of intracerebral arteries in embolization of cerebral artery arteriovenous malformations. This procedure can also be used in stereotaxic transcerebral thrombosis of intracranial aneurysms by injection with tissue adhesive. This system gives lower radiation dosage to patient and operator, decreases procedure time, and allows instantaneous retrieval of information.
