1

Diagnostic gold standard for DVT

Venography

2

Phlegmasia alba

obstructive proximal DVT compromising arterial flow and tissue death, possible life/limb loss

3

May Thurner Syndrome

Left iliofemoral DVT due to venous compression by right iliac artery causing DVT, swelling, and/or pain

4

4 T score for presumptive HIT

Thrombocytopenia
Timing of platelet count fall (5 hours-2 days after heparin initiation)
Thrombosis
oTher causes of thrombocytopenia

5

HIT Type I

Mild decrease in platelets, occurs first 2 days of heparin exposure, platelet count returns to normal with continued exposure, not clinically significant

6

HIT type II

Significant. clotting and bleeding at same time, discontinue heparin immediately. Platelet drop >50% at 5-10 days after heparin exposure

7

Predictive measurement for wound healing in peripheral artery disease or arterial occlusion

TcPO2

8

TcPO2 interpretation

>40 healing range
20-40 grey zone
<20 unlikely to heal

9

Arterial disease presentation

shiny skin, lack of hair, yellow thick nails, decreased pulses, ulcers, dependent edema

10

Thromboangiitis Obliterans

"Buerger's disease" young male smokers, foot claudication, rest pain, digital ulcers, superficial phlebitis

11

Triad for thrombosis
Endothelia injury
hypercoagulobility
stasis blood
