We report a case of mechanical thrombectomy in which a new device, the Retriever, was used for acute cerebral ischemia in the setting of extensive occlusion of the left internal carotid and middle cerebral arteries. Excellent radiographic and clinical results were obtained. The Retriever is currently approved and available for foreign body extraction and for intracranial thrombectomy when used ...

False aneurysm of the intracranial arteries occurs infrequently as a complication of head injury and rarely as a consequence of other pathology. A case of false aneurysm of the supraclinoid internal carotid artery following minor intraoperative injury during clipping of a basilar-superior cerebellar aneurysm by the pterional approach is described. False aneurysm is a potential cause of recurren...

Use of transcranial Doppler has undergone much development since its introduction in 1982, making the technique suitable for general use in intensive care units. The main application in intensive care units is to assess intracranial pressure, confirm the lack of cerebral circulation in brain death, detect vasospasm in subarachnoid haemorrhage, and monitor the blood flow parameters during thromb...

METHODS Three patients with Borrelia burgdorferi infection and intracranial aneurysms are described. RESULTS All three patients had neurological symptoms. Perivascular and vasculitic lymphocytic inflammation were detected in the brain biopsy specimen of one patient. The aneurysm was located in the internal carotid arteries in two patients and in the basilar artery in one patient. The aneurysm...

Four experimental procedures were tried with the dog before one was found which enabled us to record vasomotor changes in an intracranial vascular bed, uncomplicated by alteration in vasomotor tone in the extracranial beds. This required extensive dissection and cannulation technics. In experiments in which this was accomplished by complete elimination, on one side, of the communications betwee...

Behçet's disease is an inflammatory disorder involving multiple organs. Its cause is still unknown, but vasculitis is the major pathologic characteristic. The common vascular lesions associated with Behçet's disease are aneurysm formation, arterial or venous occlusive diseases, and varices. Arterial aneurysms mostly occur in large arteries. Intracranial aneurysms hardly occur with Behçet's dise...

We evaluated the feasibility of angiographic CT (ACT) for visualizing metallic stents in three patients who underwent intracranial (n = 2) or extracranial (n = 1) stent placement to treat atherosclerotic lesions. ACT is a new technique that provides cross-sectional CT-like images based on rotational radiography performed with a rotating C-arm-mounted flat-panel detector. ACT allowed for the cle...

Endovascular balloon embolization therapy tor neurovascular lesions was first described by Serbinenko in 197 4 [1). With improved technology, including detachable balloons, minicatheters, permanently solidifying agents, and real-time digital subtraction angiography, it is now possible to treat intracranial arterial aneurysms from an endovascular approach in selected cases [2, 3] . In the case r...

Here, we present the case of a 37-year-old woman with multiple visceral artery aneurysms in the pancreaticoduodenal, inferior pancreatic and splenic arteries associated with celiac trunk stenosis. An aneurysmectomy and end-to-end anastomosis was performed for two adjacent aneurysms, while clipping with intracranial aneurysm clips were performed for the other three aneurysms. During 36-month fol...
