1

anterior tibial artery

begins at the popliteal artery and travels down the lateral calf in the anterior compartment to the level of the ankle

2

axillary artery

continuation of the subclavian artery

3

brachial artery

continuation of the axillary artery

4

cavernosal artery

supplies the corpus cavernosum with blood in the penis

5

claudication

walking-induced muscular discomfort of the calf, thigh, hip, or buttock caused by ischemia (lack of blood)

6

corpus cavernosum

the two columns of tissue in the penis that fill with blood to create an erection

7

dorsalis pedis artery

continuation of the anterior tibial artery on the top of the foot

8

femoral artery (FA)

courses the length of the thigh through Hunter’s canal and terminates at the opening of the adductor magnus muscle

9

innominate artery

first branch artery from the aortic arch (also known as the brachiocephalic)

10

ischemic rest pain

symptom of critical ischemia of the distal limb when the patient is at rest

11

popliteal artery

begins at the opening of the adductor magnus muscle and travels behind the knee in the popliteal fossa

12

profunda femoris artery

posterior and lateral to the superficial femoral artery

13

pseudoaneurysm

perivascular collection (hematoma) that communicates with an artery or a graft and has the presence of pulsating blood entering the collection

14

radial artery

branch of the brachial artery that runs parallel to the ulnar artery in the forearm

15

Raynaud’s phenomenon

intermittent digital ischemia in response to cold or emotional stress (primary) or caused by vascular occlusion or stenosis to the digits (secondary)

16

reactive hyperemia

alternative method to stress the peripheral arterial circulation

17

subclavian artery

originates at the inner border of the scalenus anterior and travels beneath the clavicle to the outer border of the first rib to become the axillary artery

18

thoracic outlet syndrome (TOS)

changes in arterial blood flow to the arms may be related to intermittent compression of the proximal arteries (or neural and venous structures)

19

tibial-peroneal trunk

arterial branch that exits after the anterior tibial artery and bifurcates into the posterior tibial artery and the peroneal artery

20

ulnar artery

branch of the brachial artery that runs parallel to the radial artery in the forearm
