TECHNIQUE OF CATHETERIZATION AND EMBOLIZATION OF THE LENTICULOSTRIATE ARTERIES

The technique of catheterization and embolization of the lateral and medial lenticulostriate arteries in humans, using 1 or 2 balloon catheters of various designs, is described. A case of a bilateral thalamic arteriovenous malformation is presented and an instance of an aneurysm of a striate artery is discussed. Because of the high probability of proximal middle cerebral artery (MCA) thrombosis, care must be taken to determine tolerance to MCA occlusion prior to embolization.
