aortography

the radiographic demonstration of the various parts of the aorta

the radiographic demonstration of the vascular structure of internal organs contained in the thoracic and abdominal cavities

demonstration of abdominal aorta and lower extremeties.

AOP- Aorta & Peripherals. Same as above

from slightly superior of the bifurcation to the feet

following the contrast media in conjuction with a step table program and DSA

it moves the table up to take pics @ different areas of the body

always make sure you take a scout pic first

demonstration of the lower extremity vessels ot the upper extremity vessels.

demonstration of the lower extremity vessels by the instillation of contrast media

• 1. arch
• 2. thoracic
• 3.abdominal

the 3 majorvessels arising off the aortic arch

with a cerebral angio

identifying congenital anomalies

it is when the left common carotid arises from the brachiocephalic artery instead of the arch itself

showing the LLC off the brach. artery

showing the LLC arising off the brach artery close to the arch

20%

a congenital anomaly

• 1. left circumflex aorta
• 2. inverse aorta- revese aorta
• 3. pseudocoarctation

its a normal arch except that the descending aorta is extending inferiorly and to the right

an arch that turns to the right instead of the left and all the major branches occur normally

a normal aortic arch and branches but the thoracic aorta also has an arch

• 1. dissections- such as a MVA (deceleration injury)
• 2. aneurysms (weakend outpouches)
• 3. coarctation ( narrowing of the aorta)
• 4. stenosis (blockage in the aorta)

for the frmoral approach

• 1. severe arteriosclerosis because a blockage may break off & go someplace else
• 2. aneurysm @ the puncture site
• 3. severe hypertension because it could make it worse and cause a stroke
• 4. abnormal coagulation profiles

femoral - approach of choice

axillary- hard for pt to hold arm up and can cause hematoma

brachial (left) used if blocked artery and the left is used in order to by pass all other structures

• . 5Fr or smaller pigtail (placed superior to the aortic valve)
• . local anesthetic such as liocaine
• . CM nonionic
• . injector

RPO- to profile the arch & eliminate superimposition of ascending & descending aorta with the CR @level T6 with a inhalation

an AP & lat on occasion

• 1. artherosclerosis
• 2. aortic stenosis
• 3. aneurysms
• 4. tumor vascularity
• 5. trauma
• 6. preoperative planning
• 7. origin of visceral vessels

• 1. abnormal coagulation profiles
• 2. severe hypertension
• 3. aneurysm @puncture site
• 4. femoral approach in severe arteriosclerosis
