DMS 102 - Unit one - Part 2

5 sections of aorta

root, ascending, arch, descending, abdominal

normal diameter of aorta:

< 3cm

Abdominal aorta transducer

2.5-5MHz curvilinear transducer

Abdominal aorta protocol in long:

from diaphragm to bifurcation

AP measure taken

Aorta protocol in transverse:

level of diaphragm, sup to renals, inf to renals and biforcation

width measurement

Full aorta protocol:

long, trans, annotate (sup,mid,inf), calipers placed outer to outer and perpendicular to the vessel walls

Iliac vessels in long:

images sup to inf

AP measurement

Iliac vessels in transverse:

images inf to bifurcation

trans measurements taken

Veins you annotated as:

sup, mid, inf

Arteries annotated as:

prox, mid, distal OR sup, Mid, Inf

Lymphadenopathy:

Abnormal sized lymph nodes

AAA stands for:

Abdominal Aortic Aneurysm​

What is an Abdominal Aortic Aneurysm​

when vessel diameter in > than 3cm or focal dilation or 1.5 x normal size

Abdominal Aortic Aneurysm​ > 5cm or rapid rate of expansion have

increased risk of rupture

Aneurysm:

1.5 x normal diameter of vessel

CIA arise at what vertabre

L4

CIA are what measurement in trans:

< 3cm

internal Iliac A supplies

blood to pelvis

external iliac artery travels

down groin and becomes femoral artery

when Iliacs are > 3cm it is considered for

surgical repair
