MOCK FINAL Flashcards
(49 cards)
all deep veins of the lower leg have at least how many valves?
10
longest vein in the body
greater saphenous vein
the POPV passes through which structure to become the femoral vein?
adductor/hunters canal
superficial veins of the upper and lower extremities
upper:
basilic & cephalic
lower:
GSV
short saph
what system holds the most % of blood and how much
venous, 75% (3/4)
spontaneous venous flow is not usually seen in what type of vessels and why
small distal vessels because velocity is too low and no calf pump effect
if you have continuous flow in the mid femoral vein, where will you see the obstruction
proximal (towards heart) to the probe, upper FV
extensive iliofemoral thrombosis producing a tight leg edema, severe pain and cyanotic mottled skin is commonly referred to as
phlegmasia cerulean dolans
DVT destroys venous valves resulting in post-phlebitic syndrome, which can lead to (3)
chronic skin changes
statis dermatitis
ulcers
virchow’s triad
- injury to vessel wall
- hypercoaguability
- stasis
during inspiration, the intraabdominal pressure increases and blood flow from the upper and lower extremity does what
lower extremity decreases while increasing flow from upper body
vessel can be at the junction of axillary and subclavian veins
cephalic
vessel can be at the junction of axillary and subclavian veins
cephalic vein
venous pressure in right atrium
0 mmHg
The BresciCimino fistula is created surgically between which vessels?
cephalic vein and radial artery
which vein is a continuation of the dorsalis pedis and lies between the tib and fib on top of the interosseous membrane
anterior tibial vein
what sonographic features diagnoses renal artery occlusion (3)
- absence of visible main renal vein
- low velocity, monophasic signals in the kidney
- no flow detected by spectral, colour or power doppler in the main renal artery
3 branches of the celiac artery
left gastric
splenic
common hepatic
real time images demonstrating the echogenic intima separated from the aortic wall are suggestive of
arterial dissection
classic symptoms associated with chronic mesenteric ischemia (4)
- post prandial pain
- ‘fear of food’ syndrome
- weight loss
- GI ulceration
renal artery flow reducing stenosis is indicated if which criteria is found (2)
Renal aortic ratio > 3.5 and a post stenotic signal is found
as renal vascular resistance increases, what happens to the diastolic flow?
decreases
how do you calculate resistive index
PSV / (PSV-EDV)
how do you calculate renal-aortic ratio/
PSV renal/ PSV aorta
