Many arteries can be seen on an arteriogram, including those of the legs, kidneys, brain, and heart. Neuroradiology. An angiogram is used to examine blood flow through your arteries. This article elaborates on the possible side effects of an angiogram. This test can help to diagnose such conditions as blood clotting, fatty plaque which increases a patient's risk of stroke, cerebral aneurysm or other vascular malformations. Events that occurred within 24 hours of angiography were The incidence of all complications was 8.5%, and the incidence of all neurologic complications was 2.6%. Also, some people may occasionally have an allergic reaction to the contrast dye. It is often performed as a semiurgent, planned investigation or linked to an interventional procedure. This highlights your blood vessels, allowing your doctor to see any problems. It is used mainly for diagnosis and for planning treatment in patients with a suspected underlying vascular abnormality. Cerebral angiography (cerebral angiogram) - diagnostic. Aim: This study was conducted to evaluate complications (minor and major) that occurred in patients who underwent modern cerebral angiography. Performance of a compression series showed a trend towards increasing the neurologic risk. The risks of angiograms include damage to the blood vessels, allergic reactions to tracer dyes, and bleeding at the site of injections and catheter insertions.Angiograms are invasive, and while the risks are low, they cannot be completely eliminated. Cerebral angiography is a test that uses X-rays and a special dye to create pictures of the blood vessels that supply the brain.. … Angiography is generally a safe procedure, but minor side effects are common and there's a small risk of serious complications. After the femoral angiogram test patient is asked to lie down on their back foe minimum 7 hours. Catheter cerebral angiography is a safe alternative or complementary procedure to noninvasive diagnostic cerebrovascular imaging that is primarily used for treatment planning. (see figure 1) What happens before an angiogram? Complications in cerebral angiography. PURPOSE: To prospectively identify risk factors for neurologic complications related to cerebral angiography. Neurological complications following cerebral angiography are rare (0.34%), but must be minimized by careful case selection and the prudent use of alternative noninvasive angiographic techniques, particularly in the acute setting. Blood vessels do not show clearly on a normal X-ray, so a special dye needs to be injected into your blood first. Sometimes a cerebral angiogram is carried out to enable doctors to give treatments directly into abnormal blood vessels. Angiogram makes way for an easy diagnosis of any blockages or narrowing in … Complications. dia, diagnosis of the angiogram, complications seen in the Neuroradiologic Department and in Table 1 Clinical indications for angiography No neurologic Neurologic Total complications complications n % n % n % of all Aneurysm/arteriovenous malformation 270 97.5 7 2.5 277 57.3 Tumor 51 96.2 2 3.8 53 11.0 MATERIALS AND METHODS: A total of 2,899 consecutive cerebral digital subtraction angiograms obtained with nonionic contrast material were prospectively evaluated. St Louis, MO: Elsevier Saunders; 2013:309-310. Review Date 6/25/2018 METHODS One thousand consecutive cerebral angiographic procedures were evaluated prospectively. Usually, cerebral angiography is used after another test has already found an abnormality.Angiography is used to help detect and diagnose acute stroke. Cerebral angiography is a procedure that makes a detailed picture (angiogram) of the blood vessels in the brain. However, it may have its own share of side effects too. Examinations were performed using transfemoral catheterization and film-screen methods.
