SUPERFICIAL VEINS OF THE UPPER EXTREMITY
CEPHALIC AND BASILIC

Distal obstruction
100
Absent pulse, abnormal arm pressures differential of >20mmHg
UEA

Spectral Aliasing is corrected by doing these
Increase the PRF, Adjust the baseline
100
When there's reverse flow in the ECA feeding the ICA, this ipsilateral vessel is occluded
CCA

SPLANCHNIC ARTERIES
CELIAC,SMA AND IMA
200
Proximal obstruction
Tardus parvus
200
Unilateral leg edema, swelling, pain, redness
LEV to r/o DVT
200
You reference this to assess negative/positive Doppler shift on the spectral display

Patient with a painful, red palpable cord in the medial ante-cubital fossa. The SVT is in.....
The Basilic Vein

THE COMMON ILIAC ARTERY BIFURCATES INTO
EXTERNAL AND INTERNAL ILIAC
300
Immediately after the stenosis
Post stenotic turbulance

Bruit, Aphasia, Amaurosis Fugax
Carotid Doppler

When there is no color on a vessel, you check these settings
Box angle PRF and overall gain
300
Loss of Phasicity(monophasic) in bilateral common Iliac veins and the LEV system.
IVC thrombus
400
This vein connects the Basilic and the Cephalic veins
Median Cubital
400
This happens at the bulb or bifurcation
Flow separation
Turbulent
400
Abdominal bruit, pain and cramping w/eating
weight loss
Celiac and Mesenteric Duplex
400
You make sure you have a 60 degree angle to the blood flow by doing this
Angle correction bar parallel to the vessel wall
400
When a thrombus is found in GSV in the proximity of CFV you follow this rule
Clot 5cm from the CFV and the length of the clot = 5cm

The lower extremity waveform is typically this....
Phasic
500
Pain triggered by walking, relieved by rest
Claudication
LEA

When scanning the calf for LEV on a large, edematous calf you switch to this image better
Lower frequency Curved Transducer
