Flashcards in Posterior Abdominal Wall and Retroperitoneum Deck (23):
1

Name the structures the psoas major muscle relates with

Kidneys, ureters, Cecum, Appendix, Pancreas, Sigmoid Colon, Lumbar lymph nodes, Nerves of posterior abdominal wall

2

Which renal vein is longer?

The left (it has to cross the aorta)

3

Does the left renal vein cross the aorta anterior to it, or posterior to it

Cross anterior to aorta (usually)

4

Which kidney is more commonly donated and why?

Left, it gives a longer vein

5

Which renal artery is longer?

The right

6

Where does the SMA arise in relation to the renal arteries and veins and then where does it run relative to these vessels?

Arises superior to them, cross over them anteriorly

7

Where does the ureter cross the iliac arteries, and does it cross anterior or posterior

Crosses external iliac just below common iliac bifurcation (into internal/external). The ureter crosses anterior to the artery/vein

8

Varicocele

Abnormal enlargement of a vein that drains the scrotum

9

What veins become dilated, resulting in a varicocele?

Veins of the pampiniform plexus

10

On which side are varicoceles more common and why?

Left, because right testicular vein enters IVC at an acute angle, which is more favorable to flow than the 90 degree angle the left testicular vein enters the left renal vein at

11

What is indicative of a positive psoas test and briefly explain how the test works

Pain is indicative of positive test. Test involves providing backwards pressure while patient flexes hip, this presses the psoas muscle against structures related to it, indicating if one of them is the source of the problem

12

Four conditions which may be suggested by a positive psoas test

Sacroiliac disease, IV disc disease, Adenocarcinoma of the pancreas, Appendicitis

13

What is the only nerve of the posterior abdominal wall that pierces the psoas muscle?

The genitofemoral (L1,L2)

14

At what level does the abdominal aorta bifurcate?

L4/L5

15

What transverse plane approximates the level of the aorta bifurcation?

The transumbilical plane (L3/L4), which is just slightly above the aortic bifurcation (L4/L5)

16

Where is the most common site of abdominal aortic aneurysm?

Below renal arteries and veins and above aortic bifurcation

17

If the IMA is compromised, where might the distal bowel get collateral flow from?

The SMA and/or inferior iliac system

18

Name the tributaries of the IVC

Common iliacs, Renal veins, Hepatic veins, Lumbar veins, Ascending lumbar veins, Inferior phrenic veins, Right suprarenal, Right gonadal

19

Arteries supplying the diaphragm

Pericardiophrenic, musculophrenic, superior phrenic, inferior phrenic

20

Veins supplying the diaphragm

Pericardiophrenic, musculophrenic, inferior phrenic

21

Which kidney is usually more superior?

Left is usually superior to right

22

Two recesses around the liver

Hepatorenal recess, subphrenic recess

23

Three ureteric constriction

Junction with renal pelvis, brim of pelvic inlet, bladder wall
