Renal Artery Stenosis

About ninety % of RAS is caused by induration of the arteries —clogging, narrowing, and hardening of the excretory organ arteries. In these cases, RAS develops once plaque—a sticky substance created of fat, cholesterol, calcium, and alternative material found within the blood—builds au courant the inner wall of 1 or each excretory organ arteries. Plaque build-up is what makes the artery wall laborious and slender. Most alternative cases of RAS square measure caused by fibromuscular abnormal condition (FMD)—the abnormal development or growth of cells on the arteria renalis walls—which will cause blood vessels to slender.
