Lesson 3 (Part 2) Flashcards
What does the gastroesophogeal junction look like?
A target
Where is the location of the gastroesophogeal junction?
Superior to the celiac trunk
Diaphragmatic crura
Linear muscular portions of the diaphragm
What are the normal congenital variations of the aorta? (5)
- 3 renal arteries
- Common hepatic artery can come off the SMA
- Right hepatic artery can come off the SMA
- Left hepatic artery originates from the left gastric artery
- Transposition
Congenital
What you have from birth
Transposition
Flipped
What is the location of the IVC?
Right of the midline
Where does the IVC bifurcates?
L5
- aorta is L4
What is the function of the IVC?
To drain blood
Where does the SVC drain blood from? (4)
- Head
- Neck
- Thorax
- Upper extremities
Where does the IVC drain blood? (2)
- Lower trunk
2. Lower extremities
Where does the IVC return the blood to?
Right atrium of the heart
Where does the right hepatic vein empty?
The right lobe of the liver
What does the middle hepatic vein empty?
Caudate lobe
What does the left hepatic vein empty?
The left lobe of the liver
Where do the renal veins empty into?
IVC
What does the right gonadal vein empty into?
The lateral aspect of the IVC
What does the left gonadal vein empty into?
Left renal vein
What do the common iliac veins empty? (2)
- Lower extremities
2. Pelvis
In a sagittal IVC scan, what is seen posterior to the IVC?
The right renal artery
What is the size of the IVC?
< 3.7 cm
What happens to the walls of the IVC during respiration?
They change shape
What is the echogenicity of the IVC? (2)
- Anechoic lumen
- Echoic walls
- not as bright as in the aorta
Congenital anomalies in the IVC (3)
- Duplication of the IVC
- statistically most common - Transposition
- left sided IVC - Absence of a portion of the IVC
- rare
Normal variants of the IVC (2)
- Multiple veins
2. Left renal veins travelling posterior to the aorta
