چکیده

The incidence of stroke would be decreased if the vertebral artery stenosis could be diagnosed early and therapy effectively. Presently, the Digital Subtraction Angiography (DSA) is a new computer-assisted radiographic procedure to diagnose the vertebral artery stenosis, and can provide clinical information for therapy. In this paper, the hemodynamic characteristics of the vertebral artery stenosis are analysed by the Computational Fluid Dynamic (CFD) method according to the DSA data from a patient with the vertebral artery stenosis in the affiliated hospital of Inner Mongolia university for nationalities, and the study results show that the proposed scheme can provide theoretical basis for diagnosing and

Carotid DSA based CFD simulation in assessing the patient with asymptomatic carotid stenosis: a preliminary study

BACKGROUND Cerebrovascular events are frequently associated with hemodynamic disturbance caused by internal carotid artery (ICA) stenosis. It is challenging to determine the ischemia-related carotid stenosis during the intervention only using digital subtracted angiography (DSA). Inspired by the performance of well-established FFRct technique in hemodynamic assessment of significant coronary st...

ارزیابی و بررسی نتایج حاصل از داپلر فراصوتی در مقایسه با آنژیوگرافی تفریقی دیجیتال در تشخیص تنگ شدگیهای شریان کاروتید داخلی

Introduction: Digital Subtraction Angiography (DSA) is the standard method for detection of carotid artery stenosis. This technique has high radiation dose. With the progress of imaging techniques, noninvasive or minimally invasive methods like the CT angiography, MR angiography and ultrasonography with Doppler or Duplex mode were applicable. This study aimed to evaluate and assesse the results...

Computational fluid dynamics analysis of tandem carotid artery stenoses: Investigation of neurological complications after carotid artery stenting.

BACKGROUND Combined extra- and intracranial carotid artery stenoses, particularly involving multiple lesions, show complex hemodynamic properties and represent a therapeutic dilemma. We used computational fluid dynamics (CFD) to investigate whether insufficient cerebral blood flow (CBF) in a 70-year-old man with tandem stenoses was the cause of aphasia and right hemiparesis after carotid artery...

Carotid angioplasty and stenting in a patient with high grade stenosis of Internal Carotid Artery associated with both vertebral arteries and contralateral carotid occlusion

Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...

Statistical analysis of the association between rheological properties of blood and atherosclerosis

The aim of this study is to investigate the effects of non-Newtonian blood rheology models on the wall shear stress (WSS) distribution in a cohort of patients-specific coronary arteries. Twenty patients with diseased left anterior descending (LAD) coronary arteries (with varying degrees of stenosis severity from mild to severe) who underwent angiography and in-vivo pressure measurements were se...
