Percutaneous transluminal cerebral angioplasty and stenting in acute vertebrobasilar ischemic stroke. Report of two cases.
Reports of cerebral transluminal angioplasty and stenting in patients with vertebrobasilar ischemic stroke are scanty. Herein we report on the use of "monorail" coronary balloon angioplasty and stent balloon mounted catheters in two patients with acute vertebrobasilar ischemic stroke, focussing on the differences and possible advantages of the "monorail" technique in comparison with the "over-the-wire" technique. In both patients, the clinical picture was characterized by progressive brainstem symptoms followed by acute loss of consciousness related to an atherothrombotic occlusion and subocclusion of the dominant intracranial vertebral artery, respectively. In one patient, superselective thrombolytic therapy and balloon angioplasty resulted in a dissection flap at the vertebrobasilar junction. The latter was treated by successful deployment of a coronary stent. In the other patient, the subocclusive lesion was directly treated by angioplasty and stenting without thrombolytic therapy. The clinical outcome was poor for one patient ("locked in" syndrome) while the other had a complete clinical recovery. In acute atherothrombotic vertebrobasilar stroke transluminal cerebral angioplasty and stenting may be successfully performed allowing vessel recanalization.
