CONTEXT Celiac artery stenosis is observed in a significant percentage of individuals in the general population. Although usually clinically silent and insignificant, due to the presence of extensive collaterals between the celiac artery and the superior mesenteric artery, celiac artery stenosis may be associated with potentially catastrophic ischemic complications in patients undergoing pancre...

a 22-year-old woman presented with acute left-sided pleuritic chest pain and dyspnea 6 days after surgery for revision of the stenotic central aortopulmonary shunt. she had a history of tetralogy of fallot (tof), pulmonary valve stenosis, ventricular septal defect and major aortopulmonary collateral artery. her waterston shunt was placed when she was 5 years old and stented and re-dilated after...

The major issues in approaching patients with renal artery stenosis relate to the role of renal artery stenosis in the management of hypertension, ie, “renovascular hypertension,” and to the potential for vascular compromise of renal function, ie, “ischemic nephropathy.” Ever since the original Goldblatt experiment in 1934, wherein experimental hypertension was produced by renal artery clamping...

BACKGROUND Atherosclerotic stenosis of the brachiocephalic artery sometimes occurs in patients with coronary artery disease, and can cause stroke during the perioperative period of coronary artery bypass grafting. CASE PRESENTATION We describe the case of a 77-year old male with severe stenosis of the brachiocephalic artery and severe coronary artery disease. He successfully underwent aorto-r...

Intimal hyperplasia, an aberrant proliferation of smooth muscle cells that causes stenosis and graft occlusion, is the primary cause failure grafts after a few years. In this way, using constructal design method, study looks at how degree, junction angle, diameter ratio affect flow through bypass goes around idealised coronary artery partially blocked. The results show effect by several factors...

<abstract> <p>We investigated a physical system for unsteady blood flow and solute transport in section of constricted porous artery. The aim this study was to determine effects hematocrit, stenosis, pulse oscillation, diffusion, convection chemical reaction on the transport. significance uncovering combined roles played by stenosis height, oscillation period, reactive rate, speed, ...

a 56-year-old man with a two year history of chronic stable angina underwent elective coronary artery bypass grafting (cabg) due to angiographic report of three vessel disease and tight stenosis at proximal part of left anterior descending artery (lad). while harvesting of radial artery (ra), the distal half of radial artery was found to bifurcate to two parallel branches with equal size. we us...

Renal Artery Stenosis (RAS) occupies a prominent place among the secondary causes of arterial hypertension (HTA), in particular resistant.
