    Angiography in small intestine diseases
    (KhNMU, 2014-04) Joseph, Moyosore Sandra; Kochubiei, Oksana
    An angiogram is an x-ray test that uses a special dye and camera (fluoroscopy) to take pictures of the blood flow in a vessel while Angiography is the method of the procedure. This procedure is to provide detailed images of blood flow in your small intestine and to look for blocked arteries. During an angiogram, a thin tube called a catheter is placed into a blood vessel. The catheter is guided to the area under study. Then an iodine dye (contrast material) is injected into the vessel to make the area show clearly on the X-ray pictures. This method is known as conventional or catheter angiogram. The angiogram pictures can be made into regular X-ray films or stored as digital pictures in a computer. An angiogram can find a bulge in a blood vessel (aneurysm). It can also show narrowing or a blockage in a blood vessel that affects blood flow. An angiogram can show if coronary artery disease is present and how chronic it is. Certain treatments can be done during this procedure. These items are passed through the catheter to the area in the artery that needs treatment. These include: • Dissolving a blood clot with medicine • Opening a partially blocked artery with a balloon • Placing a small tube called a stent into an artery to help hold it open After the x-rays or treatments are finished, the catheter is removed. Pressure is immediately applied to the puncture site for 20-45 minutes to stop the bleeding. After that time the area is checked and a tight bandage is applied. The leg is usually kept straight for another 6 hours after the procedure. This test is done when someone has symptoms of a narrowed or blocked blood vessel in the intestines, to find the source of bleeding in the gastrointestinal tract, to find the cause of ongoing abdominal pain and weight loss when no cause can be identified, when other studies do not provide enough information about abnormal growths along the intestinal tract, to look at blood vessel damage after an abdominal injury. Results are considered normal if the arteries being examined are normal in appearance. A common abnormal finding is narrowing and hardening of the arteries that supply the large and small intestine. This is called mesenteric ischemia. The problem occurs when fatty material (plaque) builds up on the walls of your arteries. Abnormal results may also be due to bleeding in the small and large intestine. This may be caused by: Angiodysplasia of the colon, blood vessel rupture from injury, blood clots, cirrhosis, tumors.
