Renal artery stenosis Renal artery stenosis Renal artery stenosis is the narrowing of one of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia. This narrowing of the renal artery can impede blood flow to the target kidney, resulting in renovascular hypertension – a secondary type of high blood pressure. Possible complications of renal artery stenosis are chronic kidney disease and coronary artery disease. Most cases of renal artery stenosis are asymptomatic, and the main problem is high blood pressure that cannot be controlled with medication. Decreased kidney function may develop if both kidneys do not receive adequate blood flow, furthermore
Middle colic artery to which they distribute branches. Middle colic artery The middle colic artery is a branch of the superior mesenteric artery that mostly supplies the transverse colon. It arises just below the pancreas. It passes inferiorly and anteriorly between the layers of the transverse mesocolon, and divides into left and right branches. The right branch anastomoses with the right colic artery, and the left anastomoses with the left colic artery, a branch of the inferior mesenteric artery. This sequence of anastomses are frequently referred to as the marginal artery of the colon. The arches thus formed are placed about two fingers’
