The recent developments in computational fluid dynamics (CFD) can be useful observing the detailed haemodynamics renal artery bifurcation for clinical evaluation and treatment. present study focuses on haemodynamic behaviour of blood as it flows through abdominal aorta-renal junction an idealistic healthy with varying angles to aorta, i.e. from 30° 90° increments 15°. This is examine effect ang...

objective: diabetes is an important risk factor for cardiovascular events. the great percent of morbidity in patients with diabetes is due to endothelial dysfunction. the present study investigated the effects of hydroalcholic extract of nigella sativa (n. sativa)  on contractile and dilatation response of isolated aorta in streptozotocin (stz)-induced diabetic rat. materials and methods: rats ...

objectives to evaluate morphologic variations at the aortic isthmus with particular attention to ductus diverticulum, a mimicker of traumatic pseudoaneurysm, and to describe differences using computed tomography (ct) images. patients and methods from december 2013 to december 2014, patients who underwent a chest ct examination after blunt trauma at our emergency department were included. aortic...

introduction: hydrogen sulfide (h2s) plays a key role in the regulation of vascular tone and protection of blood vessels against endothelial dysfunction. since the mechanism of salt impairing h2s-induced vascular relaxation is not fully clear, therefore this study was designed to investigate the role of potassium (k+) channels in the vasodilatory effects of exogenous h2s in rat aortic rings. ma...

Regional heterogeneity exists in reactivity of different vascular beds to vasoactive substances. Experiments were designed to determine if there are differences between thoracic and abdominal aorta response to acetylcholine-induced relaxation. Ten male Sprague-Dawley rats with a weighing between 200g-250g were used. The aorta was isolated and 3mm aortic rings were cut and suspended in organ bat...

Surgery to replace the aortic root with a valved tube, whether mechanical or biological, remains most widely used technique for correcting diseases affecting this segment of aorta. Although valves are usually used, they expose patients risk thromboembolic complications associated anticoagulation. We report case first Tirone David operation performed at Festoc centre in Bamako. The patient was 6...

Objective(s): Cardiovascular disease is a leading cause of morbimortality with over half cardiovascular events occurring in the asymptomatic population by traditional risk stratification. This preliminary study aimed to evaluate systemic plaque vulnerability in patients with prior Coronary Artery Disease (CAD) with a single Whole Body [FDG] PET-CT scan in terms of plaq...

In its simplest form, coarctation of the aorta (CoA) refers to congenital narrowing thoracic aorta. Usually, a significant pressure gradient between arms and legs is suggestive diagnosis. With advancement aortic imaging in our country many CoA patients are diagnosed at an adult age, but management still carries challenge. We reported case 30-year-old lady with aneurysm involving proximal left s...
