Q

Superficial vs deep veins? (4)

A

Superficial

* Smalle, superficial fascia, highly variable, drain into deep veins

Deep

* Larger, deep fascia, less variable, part of NVB

Q

Superficial fascia vs deep fascia?

A

Superficial = loose connective tissue + fat

Deep = dense connective tissue (white glistening appearance), divides limbs into compartments

Q

Where does cephalic vein drain?

A

Axillary vein

18
Q

At what point does axillary vein (where cephalic vein drains) become subclavian vein?

A

Lateral border of rib 1

19
Q

Where does basillic vein arise from?

A

Dorsal venous network

20
Q

Where is basillic vein found in the arm?

A

Medial aspect of limb

21
Q

Where does basillic vein drain?

A

Into brachial veins

22
Q

Which vein is blood normally taken from?

A

Median cubital vein

23
Q
A

…

24
Q

What are the superficial veins of the upper limb?

A

Cephalic, basillic and median cubital vein

25
Q

Superficial veins of the lower limb? (3)

A

Great saphenous, small saphenous + dorsal venous arch

26
Q

Where do great saphenous and small saphenous veins arise?

A

Dorsal venous arch

27
Q

Where is great saphenous found in leg? Small saphenous?

A

* Great saphenous = medial aspect of limb

* Small saphenous = posterior midline

28
Q
A

…

29
Q

Where does great saphenous vein drain? Small saphenous?

A

Great = femoral vein

Small = popliteal vein

30
Q

Deep veins

A

…

31
Q

Vena comitantes?

A

Veins will benefit from pulsation og artery when enclosed within vascular sheath

32
Q

How does blood flow from superficial veins into deep veins?

A

Through perforating veins

33
Q

Pathology venous ulceration?

A

* Venous pressure increases

* Damages blood vessels in skin (superficial veins e.g. great saphenous)

* Cannot heal well due to poor blood supply

* Begins to break down

34
Q

Where is the most common site of venous ulceration? Which vein is affected?

A

* “Gaiter area” = medial aspect of distal leg

* GREAT SAPHENOUS

35
Q

Effect of embolism in segmental artery? Lobar artery? Pulmonary artery? Pulmonary trunk?

A

* Segmental artery = bronchopulmonary segment infarction

* Lobar artery = lobe infarction

* Pulmonary artery = infarction of one lung

* Pulmonary trunk = arrest of circulation

36
Q

Drainage of superficial lymphatics of upper limb?

A

Follow cephalic and basillic veins

* Basillic -> cubital nodes -> lateral axillary nodes

* Cephalic -> apical axillary nodes

37
Q

Drainage of deep lymphatics of upper limb?

A

Follow deep veins - drain into lateral axillary nodes

38
Q

Where do axillary lymph nodes drain?

A

Subclavian veins

39
Q

Drainage of superficial lymphatics of lower limb?

A

* Great saphenous -> superifcial inguinal nodes -> external iliac nodes

* Small saphenous -> popliteal nodes -> deep inguinal nodes -> external iliac nodes

40
Q

Where do external iliac nodes drain?

A

Common iliac nodes then lumbar nodes

41
Q

Where do deep lymphatics of lower limb drain?

A

Popliteal nodes -> deep inguinal nodes -> external iliac nodes
