Kidney (renal) artery disease can also be caused by Fibromuscular Dysplasia, a genetic defect, which involves overgrown tissue within the artery that blocks blood flow.
Narrowing of the intestinal (mesenteric) arteries can lead to unexplained weight loss and extreme abdominal pain when eating due to lack of blood flow, which is called intestinal ischemia. It can even lead to gangrene (tissue death).
MINIMALLY INVASIVE TECHNIQUES
- Balloon Angioplasty and Stenting: A tiny balloon guided into the blocked artery inflates, pushing plaque against the walls and increasing blood flow. A metal tube (stent) remains in the vessel and keeps it wide open.
- Arterial Bypass Surgery: Blood is redirected through a grafted blood vessel to bypass the blood vessel that is damaged. A graft may be a healthy natural vein or artery, or it may be man-made.
