2 Start with the Short axis approach and place the probe near the subxiphoid area

4 Slide your probe a little more inferiorly to see the "Seagull Sign": Celiac Trunk, Splenic Artery, and Common Hepatic Artery. Using Color Doppler may help!

5 As you slide more inferiorly you should be able to see the Superior Mesenteric Artery (SMA). Occasionally you will see the Left Renal Vein between the SMA and the Aorta.

6 Measure the abdominal aorta at it's widest diameter from Outer to Outer walls. Obtain both an anteroposterior measurement and a transverse measurement if possible.

7 Next move on to the Mid Aorta by continuing to slide your probe inferiorly.

8 Take a measurement of the aorta in the Mid Aorta. Sometimes you may even see the right and left renal arteries.

9 Continue to slide your probe inferiorly to visualize the distal aorta. You may need to decrease your depth as it is usually the most superficial part of the aorta.

10 Scan all the way to the iliac bifurcation and take a measurement of the distal aorta before the bifurcation.

11 Obtain a long axis view of the aorta by bringing the probe back to the epigastric area and from the short axis view, rotate the probe 90 degrees clockwise.

12 Visualize the Celiac Trunk and the SMA coming off the aorta in long axis.

13 Measure the anteroposterior diameter. Of note the short axis view is more reliable than the long axis view for accurate measurements.

14 Cylinder Tangent Effect: Panel (A) shows an ultrasound measurement through the center of the aorta will provide the maximal AP diameter. Panel (B) shows a measurement to the side (tangent) of the aorta resulting in a falsely small aortic diameter.

15 Obtain a suprasternal notch view
1) Place the indicator towards the patient’s head.
2) Rock the tail of the probe superiorly.
3) Rotate slightly clockwise (15-20˚) towards the patient’s left shoulder.

16 Identify the Aortic Arch, Brachycephalic Artery, Left Common Carotid Artery, Left Subclavian Artery and Right Pulmonary Artery (RPA).

17 Apply color Doppler to the Suprasternal notch view. The ascending aorta should have red flow (towards probe) and the descending aorta should have blue flow (away from probe)

18 Fusiform AAA's are symmetrical, circumferential dilatations of the aorta.

19 Saccular aneurysms form as asymmetrical outpocketings of the aortic wall.

20 Recall the Stanford vs Debakey Classifications for Aortic Dissection. Use ALL the views you can including TTE, aorta ultrasound, and suprasternal views.
Remember, however, TEE and CT angio are the gold standard.

21 This transthoracic parasternal long axis view shows a echogenic dissection flap just distal to the aortic valve.

22 This suprasternal notch view shows an aortic dissection involving the aortic arch and the brachiocephalic and left common carotid artery. This particular patient presented with unilateral right sided weakness.

23 Aorta ultrasound, is a quick way to see if the aortic dissection involves the abdominal aorta.

24 Aortic regurgitation in aortic dissection will be seen as retrograde diastolic blood flow from the aortic arch, seen with Doppler. This is what causes your diastolic murmur!
