Follow-up Study after Intracranial Percutaneous Transluminal Cerebral Balloon Angioplasty.

To find the angiographic lesions specific characteristics appropriate for intracranial percutaneous transluminal cerebral angioplasty (PTCBA). Forty-two clinically symptomatic patients with 42 haemodynamically significant intracranial lesions (% diameter stenosis > 70) were treated by PTCBA between January 1992 and May 1996. Before the angioplasty treatment, the patients were classified into three groups according to the angiographic lesions' characteristics summarised as follows: type A, a short and concentric stenosis; type B, a tubular lesion, or an extreme eccentric lesion; and type C, a diffuse lesion.

Intraventricular hemorrhage after carotid stenting.

Purpose: To report an important complication related to carotid stenting.

Methods And Results: A 71-year-old man with symptomatic subtotal occlusion of the left internal carotid artery had a 30-mm lesion treated percutaneously with implantation of 2 stents. Although the procedure was completed satisfactorily, left intraventricular hemorrhage occurred 4 hours later, possibly related to hyperperfusion injury.

Short-term arteriographic and clinical outcome after cerebral angioplasty and stenting for intracranial vertebrobasilar and carotid atherosclerotic occlusive disease.

Background And Purpose: The safe performance of percutaneous transluminal cerebral angioplasty for intracranial atherosclerotic lesions requires that the risk of complications, such as acute occlusion or symptomatic dissection, and restenosis be reduced. Our purpose was to assess the effectiveness, safety, and short-term arteriographic and clinical outcome of cerebral angioplasty and stenting (CAS) for intracranial vertebrobasilar and distal internal carotid atherosclerotic occlusive lesions.

Methods: Between March 1998 and November 1998, 10 patients with 12 intracranial atherosclerotic lesions of the vertebrobasilar artery and the distal internal carotid artery underwent treatment with flexible balloon-expandable coronary stents.

Stenting treatment for intra- and extra-cranial atherosclerotic diseases.

The purpose of this study was to investigate the effect, safety and short-term outcome of stenting treatment for extra- and intra-cranial atherosclerotic diseases. Forty-one patients underwent stenting treatment using coronary and biliary stents. Eleven patients had tubular or diffuse high-grade stenoses not amenable to standard balloon angioplasty involving intra-cranial arteries, while in thirty, extra-cranial arteries were involved.

Balloon angioplasty for embolic total occlusion of the middle cerebral artery and ipsilateral carotid stenting in an acute stroke stage.

A 66-year-old man suffering from neurologic symptoms caused by acute embolic total occlusion of the left middle cerebral artery was treated successfully with balloon angioplasty, and an ipsilateral carotid stenosis subsequently was dilated with stenting. The patient's clinical outcome 30 days later was favorable. This therapeutic option may prove to be a useful means of treating a patient with acute stroke, embolic total occlusion of the middle cerebral artery, and an ipsilateral carotid stenosis.
