1

Within the popliteal fossa, the popliteal artery bifurcates to give which two branches?

Anterior tibial artery

Posterior tibial artery

2

The dorsals pedis artery is a continuation of which artery?

Anterior tibial artery

3

The medial and lateral plantar arteries of the foot are bifurcations of which artery?

Posterior tibial

4

The subclavian artery passes under which bone?

Clavicle

5

Within the cubital fossa the brachial artery bifurcates to give which 3 branches?

Radial artery

Ulnar artery

6

Why does untreated occlusion of an en artery result in infarction?

End arteries (e.g digital arteries) are the only blood supply to a given area of the body - there are no collaterals which means no alternative blood supply

7

Describe the location of the brachial artery pulse

Medial to the biceps tendon in the cubital fossa

8

Where does the common carotid artery bifurcate in the neck?

Anterior to the sternocleidomastoid muscle at the level of the upper border of the thyroid cartilage

9

Describe the location of the radial artery pulse

Lateral to the tendon of flexor carpi radialis

10

Describe the location of the femoral artery pulse

Inferior ro the midpoint of the inguinal ligament

11

Describe the location of the popliteal artery pulse

In the popliteal fossa immediately posterior to the knee joint

12

Describe the location of the posterior tibial artery pulse

Between the posterior border of the medial malleolus and the achilles tendon

13

Describe the location of the dorsalis pedis artery pulse

Medial to the tendon of extensor hallucis longus

14

List some causes of ischaemia

Left ventricular failure (reduced arterial perfusion)

Right sided cardiac failure
(increased venous drainage pressure causes back pressure)

Aneurysm
Atherosclerosis
Tumours
Compartment syndrome

15

Name the different deep fascia of the upper limb

Pectoral fascia
Deltoid fascia
Brachial fascia
Antebrachial fascia

16

Name the different deep fascia of the lower limb

Fascia lata
Iliotibial tract
Crural fascia

17

What is compartment syndrome?

When a vessel bleeds within one fascia compartment and causes compression of other structures

*requires urgent fasciotomy

18

Describe the location of the cephalic vein

Runs in the deltopectoral groove
Lateral aspect of the limb
Drains into the axillary vein

19

The cephalic vein becomes the subclavian vein at what level?

Lateral border of rib 1

20

Describe the location of the basilic vein?

Medial aspect of the limb
Drains into the brachial vein

21

Describe the course of the great saphenous vein

Arises from the dorsal venous arch
Medial aspect of the limb
Drains into the femoral vein

22

Describe the course of the small saphenous vein

Arises from the dorsal venous arch
Runs along the posterior midline of the leg
Drains into the popliteal vein posterior to the knee

23

Which are the only two veins in the body which are not bilateral?

SVC

IVC

24

What is the most common site of venous ulceration?

Gaiter area

(medial aspect of the distal leg)

25

With regards to DVT and PE, a thrombus would cause what kind of infarction if it occludes a small peripheral artery?

Small wedge infarction

26

With regards to DVT and PE, a thrombus would cause what kind of infarction if it occludes a segmental artery?

Bronchopulmonary segment infarction

27

With regards to DVT and PE, a thrombus would cause what kind of infarction if it occludes a lobar artery?

Lobe infarction

28

With regards to DVT and PE, a thrombus would cause what kind of infarction if it occludes a pulmonary artery?

Infarction of one lung

29

With regards to DVT and PE, a thrombus would cause what kind of infarction if it occludes the pulmonary trunk?

Complete occlusion by a saddle embolus arrests the circulation

30

Superficial lymphatics generally follow veins. Describe the drainage of lymphatics following the basilic vein.

Cubital lymph nodes then lateral axillary lymph nodes
