Q

Klippel Trenaunay Weber

A

chronic DVT,

AVM,

varicose veins,

port wine stains

Q

May Thurner syndrome

A

compression of left common iliac vein by right common iliac artery

treatment with stent

Q

phlegmasia cerula dolens

A

blue painful leg iliofemoral DVT

Q

acute thrombus

A

dilated

noncompressible

low level echoes

poorly attached

spongy

homogeneous

smooth edges

flow around

Q

chronic thrombus

A

contricted

compressible

bright echoes

well adherent

rigid

heterogeneous

rough edges

flow through

Q

color flow does not establish patency

A

aids in defining thrombus

absence of color does not mean thrombosis

presence of color does not exclude thrombosis

Q

must include terminal GSV and SSV

A

venous exams

Q

SSV

A

drains to the popliteal or gastrocnemius vein

can drain to SSV above popliteal

Q

GSV located between which 2 fascia

A

between deep muscular fascia and saphenous fascia

Q

drainage of gastrocnemius veins

A

into popliteal vein

Q

drainage of soleal veins

A

into posterior tibial and peroneal veins

Q

deep or superficial: gastrocnemius veins

A

deep

Q

criteria for vein aneurysm

A

1.5 x

Q

normal flow in perforator

A

superficial to deep

Q

tip for poorly seen calf veins

A

try curved probe

Q

GSV >5.5 mm

SSV > 3.5 mm

A

for reimbursement

Q

Paget-Schroetter syndrome

effort thrombosis

A

subclavian vein compressed between first rib and scalene muscle

results in venous thrombus and flow obstruction
