The flashcards below were created by user JenniferHodges on FreezingBlue Flashcards. What would you like to do?


  1. What is angiography?
    Radiographic demonstration of blood vessels after the injection of contrast media.
  2. Who is on the angiography team?
    Radiologist/cardiologist, nurse/surgery technologist, RT
  3. What are the basic imaging steps of angiography?
    • Vessel catheterized under fluoroscopic guidance
    • Injector delivers preset amount of contrast media.
    • Rapid rate of image acquisition
  4. What are some contraindications of angiography?
    • Contrast media allergy,
    • Impaired renal function
    • Blood-clotting disorders
    • Unstable cardiopulmonary/neurologic status
  5. What are some contraindications of angiography?
    • Bleeding at the puncture site
    • Thrombus formation
    • Embolus formation,
    • Infection
    • Contrast reaction
  6. What equipment is needed for angiography?
    • Catheters
    • Physiologic monitoring equipment
    • Pressure injector
    • Fluoroscopic
    • Imaging equipment
    • Image recording equipment
  7. What are some characteristics of catheters used in angiography?
    • Long, thin tubes placed in vessels; vary in length, shape, diameter; radiopaque, presterilized, preshaped,
    • disposable
  8. What does the physiologic monitoring equipment do during angiography?
    • Monitors and records vital patient data
    • Takes ECG and pressure readings
  9. What are the requirements of the fluoroscopic
    imaging equipment?
    Must provide maximum resolution and produce radiation for long periods of time.
  10. What type of imaging recording equipment is used during angiographic procedures?
    • Vidiotape
    • Cineangiographic recording
    • Digital
  11. List the six types of angiographic procedures
    discussed in class and include indications of each plus other pertinent notes.
    • . 1) Cerebral
    • angiography – radiographic study of blood vessels of the brain
    • - Vascular stenosis
    • - Aneurysm
    • - Trauma
    • - Arteriovenous malformation
    • - Carotid arteriograms are the most common

    • 2) Thoracic angiography – study of
    • ascending aorta, arch, descending aorta,
    • -Pulmonary vessels
    • - Aneurysm
    • - Congenital abnormalities
    • - Vessel stenosis and embolis
    • - Trauma

    • 3) Angiocardiography – radiologic imaging of the heart and associated structures
    • - Coronary artery disease and angina
    • - Myocardial infarct
    • - Valvular disease
    • - Congenital heart anomaly
    • - a.k.a. cardiac catheterization

    • 4) Abdominal angiography – study of abdominal vasculature
    • - Aneurysm
    • - GI bleed
    • - Trauma
    • - Stenosis or occlusion

    • 5) Peripheral angiography – study of peripheral vasculature
    • - Atherosclerotic disease
    • - Vessel occlusion and stenosis
    • - Embolus and thrombus
    • - Can be arteriogram or venogram

    • 6) Lymphography – study of lymph nodes and vessels
    • - Assessment of lymphatics in staging of malignancies
    • - Assessment of Hodgkin’s lymphoma
    • - Peripheral swelling
    • - Lower limb procedures are most common
  12. What is vascular intervention and what
    procedures are performed?
    Procedures that intervene in a disease process and provide therapeutic outcomes.

    • Transcatheter embolization,
    • Percutaneous transluminal angioplasty
    • Insertion of venous devices.
  13. What type of venous access devices are inserted
    during vascular intervention?
    • Peripherally inserted central catheter
    • Hickman line
    • Subcutaneous port
  14. What alternate modalities can sometimes be used instead of angiography?
    • CT
    • MRI
    • Nuclear Medicine
    • Ultrasound
