Technique of catheterization and embolization of the lenticulostriate arteries

✓ The technique of catheterization and embolization of the lateral and medial lenticulostriate arteries, using one or two balloon catheters of various designs, is described. A case of a bilateral thalamic arteriovenous malformation is presented and a further instance of an aneurysm of a striate artery is briefly 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.
