It is well known that neurofibromatosis is one apparent etiology for the type of intracranial arterial occlusive disease known as moyamoya disease [1-4]. All previously reported cases of neurofibromatosis with moyamoya disease have had involvement only of the intracranial carotid circulation (supraclinoid internal carotid artery, middle cerebral artery, anterior cerebral artery) [1 -4]. We repo...

A rare case with a ruptured aneurysm of pericallosal artery and extensive hemorrhage located predominantly in the contralateral cerebral hemisphere,evaluated by computed tomography and angiography, was reported. The clinical, radiological and surgical findings of a ruptured aneurysm of pericallosal artery were analyzed. The variable CT patterns of ruptured aneurysms of anterior cerebral artery ...

Circle of Willis (CoW) plays a significant role in maintaining the blood supply for the brain. Specifically, when the stenosis occurs in the internal carotid artery (ICA), abnormal structures of CoW would decrease the compensatory capacity, leading to the local insufficiency of cerebral blood supply. The present paper built a series of lumped parameter models for CoW, and simulated the blood re...

Pituitary apoplexy followed by cerebral infarction is rare. In this report, we present a 42-year-old man who had been diagnosed of pituitary adenoma presented with a sudden onset of unconsciousness, left hemiplegia and right ptosis. Investigations revealed the development of pituitary apoplexy. The extension of tumor mass compressed the supraclinoid portion of the right internal carotid artery,...

The analysis of medical histories 129 patients aged 20 to 59 years, who suffered acute cerebrovascular disorders (AСVD) the ischemic type (IT), and participated in ATO-JFO was carried out. Anomalies cerebral arteries were found all them. A significant role hypoplasia right posterior artery, aplasia connective, left anterior as well pathological S-shaped tortuosity internal carotid vertebral the...

AIM To define neonatal pial middle cerebral artery infarction. METHODS A retrospective study was made of neonates in whom focal arterial infarction had been detected ultrasonographically. A detailed study was made of cortical middle cerebral artery infarction subtypes. RESULTS Forty infarctions, with the exception of those in a posterior cerebral artery, were detected ultrasonographically o...

We present a case in which angioplasty alone and stent-assisted angioplasty were performed in the same patient to treat medically refractory intracranial stenoses. This elderly patient with presumed intracranial atherosclerotic disease underwent angioplasty alone for his anterior cerebral artery stenosis. Stent-assisted angioplasty was used for treatment of his ipsilateral middle cerebral arter...

BACKGROUND AND PURPOSE Few data are available on the frequency and location distribution of fenestrations of intracranial arteries. We used 3D rotational angiography of all intracranial arteries in a cohort of 179 patients with suspected intracranial aneurysms to assess the prevalence and location of fenestrations and the relation of fenestrations to aneurysms. MATERIALS AND METHODS Of 179 pa...
