What is the connection between angiograms and stents?
angiograms and stents are tools of angioplastics used to correct clogged arteries and improve cardiovascular health. Angioplasty is a medical procedure that uses stents to violent blood vessels that have plaque walls, which dangerously limits the amount of oxygen to the heart. To identify the blocked arteries that need to hold open stents, doctors give patients angiograms, which are imaging tests capable of creating a visual outline of the arteries. Because angiograms are usually performed as an immediate prelude to angioplasty, patients may have angiograms and stents on the same day, leading to rapid procedure and stay in one night.
During the traditional angiogram, the catheter is inserted into the arm or foot of the patient and injects the contrasting dye into the blood vessels. The patient is administered by electromagnetic radiation or X -rays or X -rays. Images made of X -rays show the outline of the arteries, with a contrasting dye allowing PhysIcians to see which arteries are wide enough for proper blood flow and which are too narrow. Based on these images, the doctor will determine which arteries need stents in them to expand the width.
stents are non -corrosive metal braces that open the artery to improve circulation. Because traditional angiograms and stents require catheters, the surgeon usually retains the same catheter used for angiogram and uses it to insert a stent. First, the deflated balloon is inserted into the catheter into the selected artery and then inflates to compress the plaque and mark the place for the stent. Then the stent is inserted into the artery; The balloon and catheter are removed.
Two unconventional angiograms are circumvented by the use of catheters. Computed tomography (CT) angiograms and magnetic resonance resonance angiograms (MRA) use lines of intravenous therapy (IV) embedded into foot or arm injection arms into the patient. In such a caseCH must be inserted only for the location of the stent.
patients who risk need angiograms and stents include suffering cardiovascular diseases, peripheral diseases, renonovascular problems and deep venous thrombosis. Other candidates are people over 60 years of age, especially people with high fat diet or those who have high cholesterol. The main symptom that angiograms and stents could be needed is sharp pain or tightening in the chest. The benefits of angioplasty include a reduced risk of heart attack and avoiding blood clots - although some patients highly sensitive to clotting must take medication to prevent blood clotting around the stent.
