1

Varicose veins

Tortuous, dilated, elongated, thickened veins with non-functional & incompetent valves

2

ABPI

Measure BP in both arms
Measure BP in both ankles, dorsalis pedis & posterior tibial

Ankle BP - arm BP = 1.0 = normal

>1 = calcified arteries

3

Warfarin

Factors II, VII, IX, X
Measure PT / INR = time takes for blood to clot (ratio as compares time to normal person)
Indications: prophylaxis of PE, DVT, prosthetic graft, prosthetic heart valve
Therapeutic INR range = 2-3
Therapeutic INR range with prosthetic heart valve = 2.5-3.5
Give OD at 6pm
Start on LMWH at same time and continue for 5 days

4

Virchows triad (blood clot)


1) alterations in blood flow (immobilisation, pregnancy, obesity)
2) factors affecting the vessel wall (surgery)
3) factors affecting blood (thrombophilia, COCP)

5

Antiplatelet drugs

Aspirin
Clopidogrel

6

Heparin

Treatment of DVT/PE
After acute MI
Prophylaxis low dose to prevent PE/DVT
Measure APTT

7

Beurgers test - 3 signs

1) Pallor of sole of foot on elevating leg
2) Delayed re-perfusion on lowering
3) Reactive hyperaemia

8

Critical limb ischaemia

2 weeks of:
- necrosis, ulcer, gangrene
- rest pain requiring opiate analgesia
ABPI

9

ABPI acute limb ischamia

Watchful waiting
Best medical management - statins, BP, DM
Endovascular - angioplasty & stenting

Basically shrinks the vessels
