Extracranial/Intracranial Vascular Disease Symptoms and Treatment - UPMC
Extracranial vascular disease refers to carotid or vertebral stenosis outside the skull. Intracranial vascular disease involves the arteries within the skull or at the base of the skull.
Cause and Mechanisms of Intracranial Atherosclerosis
2014年10月14日 · Intracranial arteries, especially the smaller arteries (ACA, PCA, and cerebellar and communicating arteries), show a distinct structure such as the lack of vasa vasorum and an external elastic lamina and only a few medial elastic fibers compared with extracranial arteries.
Aim of the work: To determine the difference between intracranial and extracranial steno-occlusive atherosclerosis and its correlation with risk factors of acute ischemic stroke using Magnetic Resonance Angiogram (MRA) and/or Computed …
Functional Arterial Anatomy of the Cranial Base
2023年1月27日 · Two main vascular routes supply the brain, internal carotid arteries (ICAs) and vertebral arteries. The external carotid artery (ECA) mainly supplies the skin, muscle, and skull; thus, neurointerventionalists should be aware of ECA‐ICA, ECA‐vertebral artery, and extracranial–intracranial anastomoses.

The Differences Between Intracranial and Extracranial Arteries. Feature: Intracranial Artery: Extracranial Artery: Muscle Content: Less-developed media with a lesser number of smooth muscles: Muscular media with abundant elastic fibers: Internal Elastic Lamina: Well-developed with elastic fibers: Less prominent:
Concurrent intracranial and extracranial artery stenosis and the ...
2020年8月13日 · We intended to investigate the association between intracranial atherosclerotic stenosis (ICAS), extracranial atherosclerotic stenosis (ECAS) and the prognosis of patients with TIA, TSI and DWI-negative AIS.
Histology-Verified Intracranial Artery Calcification and Its Clinical ...
2022年1月24日 · Considering the highly improved abilities of novel imaging technologies in differentiating intimal and medial calcification within the large intracranial arteries, this review aimed to describe the histological and imaging features of two types of IAC, as well as the risk factors, the hemodynamic influences, and other clinical impacts of IAC occ...
Intracranial and Extracranial Atherosclerosis: More Similar Than ...
2019年11月28日 · Besides a clear majority (96%) of patients having at least 1 intracranial arterial vessel wall lesion, there is a significant association of intracranial atherosclerotic burden with atherosclerotic disease in all examined extracranial arteries (ie, carotid intima-media thickening, 50%–100% carotid stenosis, an ankle-brachial index of ≤0.9 ...
Intracranial versus extracranial artery dissection cases presenting ...
Background: To compare the clinical and radiologic characteristics, possible stroke mechanisms, and prognosis of intracranial artery dissections (IADs) with those of extracranial artery dissections (EADs) presenting with cerebral infarction.
