Go for Vascular Stenting to Diagnose Artery Blockage

Angiography is a minimally invasive treatment procedure that is performed for widening the blocked arteries or vein to improve the flow of blood in the body. In this procedure imaging techniques are used to guide a balloon-tipped catheter and thin plastic tube to widen the narrowed or obstructed blood vessel. It uses an empty and collapsed balloon on a guide wire that is passed through the narrowed locations and then inflated to a fixed size using water pressure some 75 to 500 times normal blood pressure. The pressure of water flow removes the fatty deposits pertained in the arteries. Common complications of angioplasty are allergic reactions to kidney problem, contrast dye, bleeding, weakening of the arterial walls and reblocking of the treated artery.

During angioplasty treatment process, a small fittingly wire tube, also called as stent, is permanently placed in the newly opened artery that helps it to remain open. There are mainly two types of stents such as bare stent and covered stents. First time the balloon angioplasty was performed during bypass surgery in May, 1977 in St. Mary’s Hospital in San Francisco, California.

There are certain conditions when we need the angioplasty surgery that may be with or without vascular stenting. These conditions include the narrowing of large arteries. They can be classified as-
  • A gradual process in which cholesterol and other fatty elements deposit in the arteries.
  • Peripheral artery disease (PAD), in which patient witnesses a narrowing of the arteries in the legs or arms.
  • Renal vascular hypertension, this is high blood pressure occurs due to narrowing of the kidney arteries.
  • Carotid artery disease, it occurs due to narrowing of the neck arteries of the brain.
  • Narrowing in dialysis fistula or grafts
  • Coronary artery disease, it happens due to the blockage in the arteries that carry blood and oxygen to the heart.
Talking about the benefits of the Angioplasty and Vascular Stenting, it needs less surgical interventions. The balloon angioplasty and stent placement are less invasive and relatively low-risk and cost effective. It can be performed by using local anesthesia.  Vascular Stenting requires minimum surgical incision and can be recovered in a very short time.
