How to do an annotation
1.) scan place (ex. Sagital)
2.) organ of interest (ex. Aorta)
3.) portion of organ (ex. Superior)
Sagital aorta mid
Anterior to spine
Posterior to liver (smaller section)
1-2 cm inferior to SMA
Arterial Vasculature should normally display….
An anechoic lumen with bright echogenic walls that delineate (portray) it from adjacent structures
Larger vessels often display…
Pulsatility, which assists in proper identification
In Sagital or coronal scanning plane, the aorta is seen as a…
Longitudinal, tubular, highly pulstile structure.
Slightly anterior and to the left of the spine.
The proximal portion of the abdominal aorta often appears…
Curvilinear as if courses posteroanteriorly after passing behind the diaphragm into the retroperitoneum
The aorta continues to run anteriorly until it ___________.
Bifurcates
The aorta is often __________; which makes identification of a longitudinal portion difficult
Tortuous
One should attempt to identify the layers of the abdominal aorta to assist in….
Pathology
The tunica intima often appears as…
A bright echigenic line on the innermost portion of the vessel wall
The tunica media is believed to be represented by the…
Echo-free area between the bright tunica intima and tunica adventitia
The tunica adventitia is the…
Fibrous outermost section of the vessel that appears as a moderately bright line differentiating the vessel from other structures
The branches of the aorta that are demonstrated w reasonable consistency on the ultrasound are the…
CA, SMA, Renal Arteries, and Common Illiac Arteries
The CA is visualized at….
A level slightly superior to the body of the pancreas.
In the transverse plane, the CA and it’s branches are recognizable by displaying…
The characteristic shape of a seagull
Seagull:
The longitudinal sections of the SPA and CHA represent the ______.
The shirt tubular section of the CA represent the _______.
Wings.
Body.
Longitudinally, the superior mesenteria artery (SMA) appears as a
linear structure branching anteriorly from the aorta slightly into nferior to the CA.
It runs inferiority and parallel to the aorta.
In axial sections. The SMA is seen as a…
Small round, anechoic structure surrounded by bright, exhigenic parapancreatic fat directly posterior to the splenic vein.
The renal arteries are usually most easily seen in the _________ scanning plane. They are seen as.…
Transverse.
Small diameter, curvilinear, longitudinal structures, branching right and left laterally from the aorta, and then running toward their respective kidney .
The axial RRA can usually be seen…
Directly posterior to a longitudinal section of the IVC
The aorta ________ into the common iliac arteries
Bifurcates
At what level does the aorta bifurcate into the common iliac arteries?
Add about the level of the umbilicus or fourth lumbar vertebrae.
Just before the aorta bifurcates, the distal portion of the aorta
Narrows slightly
Bifurcation is mostly easily demonstrated in the __________ scanning plane. One will see the.….
Transverse.
Single axial distal portion of the aorta divided into two separate axle vessels, as the transducer is angled or moved inferiorly.
What assessment of the abdominal aorta and its branches is extremely useful in understanding, systolic and diastolic flow
The Doppler assessment
The aorta and its branches are primarily evaluated to detect….
Aneurysms and stenosis. However, arterial graphs are routinely evaluated as well.
The stenosis of which arteries can be identified with the aid of Doppler sonography?
Stenosis of the CA, SMA, Renal artery, and common iliac arteries
Graphs can be evaluated for patency and complications using….
Doppler sonography
What is often a causative factor in disease states
Stenosis
