background: the interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries. objective: to understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from c...

variation of the branches of the external carotid artery (eca) is well known, but it is extremely rare for the occipital artery (oa) to arise from the internal carotid artery (ica). a 87-year-old man was found to have this anatomical variation on the right side by threedimensional computed tomography angiography for vascular mapping of the carotid arteries before superselective intra-arterial c...

background: a precise understanding of the mechanism of human neointimal stenoses and atherosclerotic fibrous plaques , which give rise to thromboses in vital arteries, requires a suitable animal model that would mimic the same characteristics well. we developed a rabbit model of neointimal stenosis and fibrotic plaque rupture in the carotid artery to visualize the lesion progress and to charac...

background: the incidence of stroke after coronary artery bypass grafting (cabg) is between 0.9% and 6.7%, which significantly increases in-hospital and out-hospital costs. this study was designed to evaluate the prevalence of significant carotid stenosis and its risk factors in cabg. methods: in total, 2044 consecutive patients undergoing elective cabg were investigated through a pre-operative...

Abstract Background: Renal transplantation (RT) is the transplantation of a kidney into a patient with end-stage renal disease and has become the treatment of choice for most patients with end-stage renal disease. The knowledge of renal vascular variations is of a great importance for the surgeons who approach the kidneys from the retroperitoneal o...

background: pulse wave velocity (pwv) is widely used for estimating the stiffness of an artery. v arious invasive and non-invasive methods have been developed to determine pwv over the years. in the present research , the non-invasive estimation of the pwv of large arteries was used as an index for arterial stiffness. methods: a dynamic model based on the navier-stokes equations coupled to elas...

background: although the risk factors of ischemic strokes are well defined, there is slight information about their relations with the etiologies of ischemic strokes. this study investigated the distribution of ischemic stroke risk factors and their connections to diverse etiologies of cerebrovascular attack (cva) and specific ischemic regions of brain. methods: in this cross sectional study , ...

objective(s) diabetes related dysfunction of resistance vessels is associated with vascular occlusive diseases. vasorelaxant agents may have a role in control of diabetic cardiovascular complications. gamma aminobutyric acid (gaba) has demonstrated to cause vasorelaxation. the present study was designed to determine i) the vasorelaxatory effect of gaba on diabetic vessels and ii) the role of en...

conclusions in most cases, the conus artery can be visualized in cardiac ct. a description of the conus artery should be a part of the standard clinical coronary ct angiography description. objectives to examine whether it is possible to visualize the conus artery in multi-slice computed tomography (ct). patients and methods in 79 consecutive patients (aged 56 ± 12.9 years; 13 women), 64-slice ...

background: stroke is a multifactorial disorder, the most common cause being arterial occlusion. transcranial doppler ultrasonography (tcd) is a common non-invasive method available for assessment the arterial blood flow of the brain. objective: assessment the hemodynamic parameters of cerebral arteries, using tcd device in patients suffering ischemic stroke. materials and methods: this descrip...
