ANGIO Flashcards
Catheter sizes
4 Fr to 7 Fr
positive contrast symptoms
nausea, uncomfortable burning in 1 of 10 patients
positive contrast example
visipaque and omipaque
water soluable, non ionic, iodinated
Sheaths purpose
to reduce vessel trauma
Coronary Angio
diagnose and treat CAD
Biplane imaging in thoarcic aortography because
PA and lateral obtained with one contrast injection
Thoracic Aortography centering
T7
When to use negative contrast
below diaphragm
biplane in cerebral angiogram
smaller amount of contrast needed
Patients with known sensitivities to contrast may require
pre med with antihistamine / steroids
two types of stents
bare metal
drug eluting
blood vascular and lymphatic both carry
O2, nutrients to tissue
collect and transport CO2
stents
metal scaffold that is deployed using a balloon
what venography is performed before TIPS
portal and hepatic venography
positioning for cerebral angio
MSP of head perpendicular to headrest
why do stents stay in artery permanently
to prevent restenosis
why is patient instructed not to consume solid foods in prep.
to reduce possibility of aspiration of vomitus
TIPS
creates an artificial low pressure pathway between the portal and hepatic veins
Purpose of thoracic aortography
rule out aortic aneurysm
evaluate congenital or postsurgical conditions
evaluate aortic dissection
catheter approach for upper extremity
Seldinger introduces catheter through femoral artery
Coronary arteries supplying left ventricle
L ant. descending and circumflex
purpose of abdominal aortography
abd aortic aneurysm, occlusion, atherosclerosis
why are lower extremity arteriograms performed
to determine whether atherosclerotic disease is cause of claudication
IOML in cerebral
perpendicular to horizontal plane
