What arteries are the most catheterized?
femoral, axillary, and brachial
Aortography is selectice or nonselective?
nonselective
How is Aortography accomplished?
place a catheter at the desired level of the aorta.
what are Thoracic Aortography indications?
Aortic Dissection, congenital or postsurgical conditions.
Looking at all abdominal arteries?
Abdominal Aortography
What are some abdominal aortography indications?
aortic aneurysm, occlusion, or atherosclerotic disease.
atherosclerotic?
hardening
These studies are performed to rule out atherosclerotic disease, thrombosis, embolization, occlusion, bleeding or to visualize tumor vascularity.
Selective Abdominal Arteriographic Studies
Celiac Artery carries blood to the stomach, liver, spleen, and pancreas.
Celiac Arteriogram
braches off the celiac artery, and supplies blood to the liver, stomach, duodenum and pancreas.
Hepatic Arteriogram
branches off the left of the celiac artery and supplies blood to the spleen and pancreas
splenic arteriogram
mesentary?
bowels
supplies blood to the small intestine and first portion of colon
superior mesenteric arteriogram
supplies blood to the splenic flexure, descedning colon and rectum.
Inerioro mesenteric arteriogram
supplies blood to kidneys
Renal Arteriogram
rule out thrombus or occlusion of superior vena cava
Superior vena cavagram
rule out thrombus or existence of occlusion
inferior vena cavagram
performed to evaluate traumatic injury or an arteriovenous shunt created for renal dialysis
upper limb arteriogram
Performed to evaluate thrombus?
Upper limb venograms
performed to determine if atherosclerosis is the cause of claudication?
Aortofemoral Arteriograms
Performed to rule out thrombosis of the deep veins of the leg?
Lower Leg Venogram
indications of pulmonary arteriography?
embolic disease
right side of heart sends blood to where?
pulmonary artery
term used to denote radiologic examinations of the blood vessels of the brain.
Cerebral Angiography
What are the indications of Cerebral Aneurysm?
Cerebral Aneurysms, vascular lesions, and demonstration of tumors by dis placement of blood vessels and tumor circulation
What supplies the brain with blood?
rt and lt common carotid arteries- anterior circulation

rt and lt vertebral arteries- posterior circulation
the 3 branches of the aortic arch
1. brachiocephalic

2. left common carotid

3. left subclavian
collateral circulation provided by anterior and posterior communicating arteries at the base of the brain.
Circle of Willis
phases of filming program in cerebral angiography?
arterial, capillary, venous
Performed to visualize atherosclerosis or occlusive disease of carotid, vertebral, or subclavian arteries.
Aortic Arch Angiogram
How does interventional radiology differ from other?
it is therapeutic rather than diagnostic
What types of situations is interventional radiology used?
open up stenotic or occluded arteries
Embolization of arteries
Drainage of a kidney that has blockage
Removal of stones with catheters
trap an embolus of lower leg
Reduce portal hypertension
What types of situations would you use interventional radiology dealing with embolization of arteries?
stop active bleeding sites
end blood flow to a tumor
stop or reduce blood flow to and area of the body
Why do you trap an embolus in the lower leg?
so it does not reach the pulmonary arteries
sac formed by local enlargement of a weakened vessel wall.
Aneurysm
condition in which fatty deposits on the luminal wall or an artery may cause obstruction of that artery.
Atherosclerosis
cramping of leg muscles after physcial exertion because of chronically inadequate blood supply.
Claudication
foreign material, often thrombus that detaches and moves freely in the bloodstream
Embolus
