Vascular Surgery

Renal artery is the vessel through which blood passes to the kidney to remove the body’s waste. These renal arteries originate in the heart and are also responsible for carrying oxygenated blood to the kidneys. Like other arteries the renal arteries also become blocked, the condition which is called renal artery stenosis. These arteries are affected due to several diseases such as atherosclerosis, renal artery aneurysm, fibromuscular dysplasia and vasculitis. Decreased blood flow to the kidneys often lead to hypertension. If untreated, renovascular hypertension may lead to cardiovascular and kidney problems. Treatments for renovascular hypertension refer to restore the normal blood flow to the kidney. This may be done by balloon angioplasty, use of stent to keep the artery open. Surgical technique in case of atherosclerosis include endarterectomy or bypass grafting.
