Loading flashcards...
1
____ supplies stomach, 30-40% of liver, spleen, and small and large bowel
Arterial system
2
___ supplies the small intestine, cecum, ascending and transverse colon
SMA
3
___ supplies descending/sigmoid colon and most of rectum
IMA
4
Renal arteries are ___ to SMA and ____ to renal veins
Inferior
Posterior
5
Right renal artery is
Longer than the left (further to travel)
6
Left renal artery is
Slightly higher than the right bc of the right lobe of the liver
7
Aorta passes ___ to diaphragm at the ____ and is then termed ____.
Posteriorly
Aortic hiatus
Abdominal aorta
8
SMA is __ cm distal to celiac axis
1cm
9
IMA is ___ cm proximal to bifurcation
4 cm
10
Organs with low resistance vascular beds
Liver
Spleen
Kidneys
11
Organs with high resistance vascular beds
SMA
Iliacs
12
___ renal vein is longer than ___ renal vein.
Left is longer than right
13
PV demonstrates a ___ blood flow
Hepatopetal
14
Veins in the liver with echogenic walls
PV
15
Veins in the liver with hypoechoic walls
Hepatic
16
High resistance area of body:
Don’t need constant supply
Less flow, more diastole
17
Low resistance area of body:
-Need constant supply of blood
-Even when the heart is relaxed (diastole), there is still a lot of blood flow
18
Describe arterial blood flow wave
Spikes (systolic), flows towards organ so wave is above the base line
19
Describe venous wave blood flow
Wave below baseline bc blood is leaving organ (exception: Portal vein)
20
Renal arteries have a ___ resistance wave form.
Low
-constant forward blood flow during cardiac cycle
-kidneys need constant blood supply
21
A pregnant woman has a ___ resistance blood flow to uterus.
Low
-uterus needs more blood during pregnancy
22
Celiac axis presents a ___ resistance wave form
Low
-mainly the liver and spleen need that blood
23
SMA has a ___ resistance blood flow when pt has not eaten.
High
-increase in blood flow after pt eats
24
Resistance ___ I’m SMA after the pt eats
Lowers
25
___ drain the liver
Hepatic veins
-left, right, and middle
26
IVC lies __ to rt kidney and ___ to liver before coursing through the diaphragm
Medial
Posterior
27
Ivc enters into the ___of the heart
Right atrium
28
The portal vein is ___ bc of collagen
Echogenic
29
The PV present a ___ flow
Hepatopetal
Above the baseline
30
IVC should be __-__ I’m size
2.5-3.5 cm or 25 to 35mm
31
Portal vein normal size is
1.3 cm or 13 mm
32
Prox IVC is more ___ bc of its location to the heart
Pulsatile
33
Distal IVC isn’t as ___ bc of its location away from the heart
Pulsatile
34
Hepatic veins will present a ___ blood flow
Hepatofugal- away from liver
-below baseline
35
Renal veins have a ___ flow.
Phasic
36
Hepatic veins should measure
4-6mm
37
Splenic vein should measure
4-6mm
38
SMV should measure
6-7 mm
39
Renal veins should measure
4-6mm
40
Distal IVC presents a ___ flow
Phasic
41
