What are the different kinds of angiography?

Written by : DoctorNDTV Team

A variety of common angiography procedures are:

  1. Cerebral angiography

    Cerebral angiography is used to detect aneurysms, blood clots, and other vascular irregularities in the brain. The catheter is inserted into the femoral or carotid artery and the injected contrast medium travels through the blood vessels on the brain.
  2. Coronary angiography

    In a coronary angiography, the arterial puncture is typically given in the femoral artery, and the cardiologist uses a guide wire and catheter to perform a contrast injection and x-ray series on the coronary arteries. The angiogram procedure takes several hours, depending on the complexity of the procedure.
  3. Pulmonary angiography

    Pulmonary, or lung angiography is performed to evaluate blood circulation to the lungs. It is also considered the most accurate diagnostic test for detecting a pulmonary embolism. The contrast medium is injected into the pulmonary artery where it circulates through the lung capillaries. The test typically takes up to 90 minutes.
  4. Kidney angiography

    During a kidney angiogram, the guide wire and catheter are inserted into the femoral artery in the groin area and advanced through the abdominal aorta, the main artery in the abdomen, and into the renal arteries. The procedure takes approximately one hour.
  5. Fluorescein angiography

    Fluorescein angiography is used to diagnose retinal problems and circulatory disorders. It is typically conducted as an outpatient procedure. The patient's pupils are dilated with eye drops and he rests his chin and forehead against a bracing apparatus to keep it still. Sodium fluorescein dye is then injected with a syringe into a vein in the patient's arm. The procedure does not require x rays. Instead, a rapid series of close-up photographs of the patient's eyes are taken. The entire procedure takes up to one hour.
  6. Coeliac and mesenteric angiography

    Coeliac and mesenteric angiography involves x-ray exploration of the coeliac and mesenteric arteries, arterial branches of the abdominal aorta that supply blood to the abdomen and digestive system. The test is commonly used to detect aneurysm, thrombosis, and signs of ischaemia in the coeliac and mesenteric arteries, and to locate the source of gastrointestinal bleeding. It is also used in the diagnosis of a number of conditions, including portal hypertension, and cirrhosis.
  7. Splenoportography

    A splenoportograph is a variation of an angiogram that involves the injection of contrast medium directly into the spleen to view the splenic and portal veins. It is used to diagnose blockages in the splenic vein and portal vein thrombosis and to assess the strength and location of the vascular system prior to liver transplantation.
