Objective: A case in which intracranial arterial stenosis was exacerbated 5 months after percutaneous intracranial stent retriever thrombectomy is reported. Case Presentation: In a 62-year-old male, percutaneous intracranial thrombectomy using a stent retriever was performed for acute occlusion of the basilar artery. After complete recanalization, a stenotic lesion considered to be atherosclero...

background: numerical study of angulation effects of renal arteries on blood flow has been of great interest for many researchers. objective: this paper aims at numerically determining the angulation effects of stenosed renal arteries on blood flow velocity and renal mass flow. method: an anatomically realistic model of abdominal aorta and renal arteries is reconstructed from ct-scan images and...

1. In 13 patients with hypertension and renal artery stenosis the stenosis was dilated by an intra-arterial balloon catheter under local anaesthesia. 2. In all but one instance arteriography after the dilatation showed considerable widening of the stenosed area. 3. Six patients had a temporary increase of serum creatinine that lasted only a few days. 4. In seven patients, who had a prolonged tr...

A continuous murmur like that of a persistent ductus arteriosus produced by a stenosed branch of a pulmonary artery with a post-stenotic dilatation is presented in the following case. Other abnormalities included a hypoplastic left lung, atrial septal defect, ventricular septal defect, and an absent left pulmonary artery. The literature on congenital heart disease contains increasing numbers of...

This research work has been carried out to investigate the influence of treatment parameter on flow blood in a stenosed artery presence magnetic field with heat transfer. The momentum equation governing solved by scaling it dimensionless structure aid some parameters. equations have analytically using modified Bessel and method undetermined coefficients order obtain temperature profile velocity...

This paper aims to identify and study the blood flow acoustics characteristics of different degrees stenosis in carotid artery. Blood will produce acoustics, but presence levels are expected acoustic characteristics. The simulated by using computational fluid dynamics software (CFD). Several three-dimensional models arteries that have used together with a normal/healthy artery - i.e., 30% 70% b...

This study concerns the two-dimensional structure computational results of renal artery stenosis. In this paper, turbulent flow stenosed vessel is stimulated and correlates different stages stenosis with each other. As we know that blood in most vessels laminar, but case vessel, becomes turbulent; due to blockage does not linearly produces chaos. Several liquid parameters are analyzed, such as ...

The presence of stenosis at the wall artery lead to further cardiovascular diseases such as heart attack, stroke and many more. Treatment a stenosed includes insertion catheter through which affects blood flow solute dispersion. This present study focuses on effect radius height dispersion behavior. problem is modelled using Herschel-Bulkley fluid represent rheology, with boundary conditions. A...
