17
Q

What is the most common site of atherosclerosis formation?

A

Abdominal aorta (and iliac arteries)

18
Q

How do we do an Ankle-Brachial Pressure Index?

A

Compare BP in ankle and arm
Patient lays supine - everything at the same height
ABPI = BP leg / BP arm
Normal = 0.9 - 1.2
Can also use a Doppler ultrasound probe to assess blood flow

19
Q

How does flow relate to radius?

A

Flow is proportional to radius to the power 4

20
Q

What are the signs of poor perfusion?

A 
Lack of hair
Skin problems
Ulcers
Infection 
Skin necrosis 
Loss of pulses
Cold to touch
21
Q

What is the treatment for peripheral vascular disease

A

Aspirin

Risk factor modification eg. Lipid lowering, stop smoking, BP control, control of diabetes, increase exercise

22
Q

What are the signs of popliteal aneurysm?

A

Oedema and pain in popliteal fossa

Palpable pulsation

23
Q

What injuries could cause popliteal artery rupture?

A

Fracture of distal femur

Dislocation of knee

24
Q

Describe saphenous cut down

A

Used in emergency situations when it is difficult to find a vein for venae puncture or cannula insertion
Anterior to medial malleolus
Risk of saphenous risk injury

25
Q

Describe varicose veins

A

Dilated, tortuous, superficial veins
Valve flaps fail - incompetent
Venous insufficiency can lead to ulcers

26
Q

Where does the subclavian artery becomes the axillary artery?

A

Passing lateral to the 1st rib

27
Q

Where does the axillary artery become the brachial artery?

A

Passing the inferior border of teres major

28
Q

How many segments is the axillary artery split into and what defines them?

A

3

Defined by position relative to pectoralis minor

29
Q

What do we call the arteries that supply to head of the humerus?

A

Anterior and posterior circumflex humeral arteries

30
Q

Which artery runs alongside the radial nerve in the radial groove?

A

Deep branch of the brachial artery

31
Q

Which arteries anastomose at the scapula?

A

Subscapular artery
Suprascapular artery
Dorsal scapular artery

32
Q

Which artery supplies the deep palmar arch of the hand?

A

Radial and ulnar arteries

33
Q

Which artery supplies the superficial palmar arch?

A

Ulnar artery

34
Q

The posterior and anterior interosseous arteries are branches of which artery?

A

Ulnar artery

35
Q

Where do the cephalic and basilic veins start?

A

Dorsal venous arch of the hand

36
Q

Which superficial vein of the arm runs laterally and which runs medially?

A 
Lateral = cephalic 
Medial = basilic
37
Q

Deep venous drainage of the arm arises from which structure?

A

Deep palmar arch (venous?)
