Al-though the plaque burden of intracranial artery is greater in Asian population, little data are available re-garding the relationship between Hcy levels and intra-cranial plaque stability. Four main ultrasound approaches ( Fig. Such dissection does not correlate well with systemic conditions such as emboli, thrombotic or hemorrhagic tendencies or hypertension, nor with disease of blood vessels such as atherosclerosis, fibromuscular dysplasia, cystic medial necrosis or Moya-Moya … Intracranial pressure (ICP) is typically measured in mm Hg or cmH 2 O (1 mm Hg=1.36 cmH 2 0), and ranges from 5 to 15 mm Hg while supine, but it is not static. Improper regression of embryonic arteries seems to be the most probable explanation for VA fenestration. Such dissection does not correlate well with systemic conditions such as emboli, thrombotic or hemorrhagic tendencies or hypertension, nor with disease of blood vessels such as atherosclerosis, fibromuscular dysplasia, cystic medial necrosis or Moya-Moya disease.

Intracranial artery stenosis is highly prevalent in stroke patients of Asian, African, and Hispanic ancestry . Once the stent is deployed in a vessel, an inflammatory response is initiated. REVIEW. AND A new classification system divides the internal carotid artery into four parts; cervical in the neck, petrous in the base of the skull, cavernous within the cavernous sinus and intracranial above the cavernous sinus. Angioplasty with or without stent placement is a feasible procedure to dilate the vessel affected. Shin JH, Suh DC, Choi CG, Leei HK. Y1 - 1998/6. The space terminates as the glia limitans (a subpial layer formed by end-feet of astrocytes) fuses with the basal lamina of the smallest arteriole. Intracranial arterial stenosis increases the risk of stroke, and stroke recurs more frequently in patients with symptomatic intracranial arterial stenosis than in those without.1 However, few vascular imaging studies of intracranial arterial stenosis have been done in Caucasian populations, because it is less common than in Asian populations.2,3 In The Lancet Neurology, Robert Hurford and colleagues4 … This finding is not universal; the Trial of Cilostazol in Symptomatic Intracranial Arterial Stenosis (TOSS)-2 found instead that initial ischaemic lesion pattern was a better predictor than the presence of … Inclusion criteria for the current study were (1) 50% to 99% stenosis of one of the following arteries in the posterior circulation: intracranial vertebral artery, basilar artery, PCA, or PICA; (2) a transient ischemic attack or stroke in the distribution of the stenotic artery; and (3) therapy with aspirin or warfarin.

It is a pity when valuable research such as that described by Faisal Mohammad Amin and colleagues1 is incorrectly interpreted and used to justify misleading conclusions. The approved therapies for acute ischaemic stroke are thrombolysis with intravenous recombinant tissue plasminogen activator (rt-PA), and mechanical thrombectomy; both aim to recanalise an occluded intracranial artery. Intracranial angioplasty, with stent placement, for treatment of atherosclerosis of intracranial arteries is considered experimental, investigational or unproven. About two-third of VA fenestrations are extracranial, while one-third are intracranial. A vaguely visible longitudinal fissure was found in the midportion of the left intracranial vertebral artery.

Intracranial atherosclerosis is a well-recognized and common cause of stroke in Asian, black, and Hispanic individuals. When a tear breaches the aforementioned subendothelial elastic layer, then there is little tissue preventing extension into the subarachnoid space, thus accounting for the very high rate of subarachnoid hemorrhage. 10.1) are used to examine the intracranial arteries: the transtemporal, transorbital, suboccipital (i.e., transforaminal), and submandibular approaches. 11 (4): 329-36.
