subclavian arery
Definition
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

superficial femoral artery
Definition
courses the length of the thigh through Hunter's canal and terminates at the opening of the adductor magnus muscle
Term
thoracic outlet syndrome
Definition
changes in arterial blood flow to the arms may be related to intermittent compression of the proximal arteries ( or neural and venous structures)
Term
tibial - peroneal trunk

the abdominal aortal terminates in the _______ of the right and left common iliac arteries (approx at the level of the fourth lumbar vertebra).
Term
hypogastric
Definition
each of the common iliac arteries bifurcates into an internal iliac artery (_______ artery) that supplies the pelvis and an external iliac artery that continues distally to supply the lower extremity
Term
common femoral
Definition
the external iliac artery terminates at the inguinal ligament, where it becomes the ____ _____ artery.
Term
profunda femoris
Definition
the common femoral artery originates beneath the inguinal ligament and terminates by dividing into the superficial femoral and ____ _____ arteries.

symptoms of lower extremity occlusive arterial disease are ______ and _________ pain
Term
distal
Definition
ischemic rest pain implies critical ischemia of the _____ limb when the patient is at rest.
Term
15
Definition
before beginning the examination, there should be a ____ min rest period to allow the pts blood pressure to stabilize and legs to recover from walking to the examination room.
Term
supine; heart
Definition
segmental pressures are obtained with the patient in the ____ position; the legs should be at the same level as the _____ because this position prevents hydrostatic presure artifact.
Term
20%
Definition
to obtain pressures comparable with direct intrarterial measurements, the blood pressure cuff must have a width ____ greater than the diameter of the limb.
Term
elevated ; lower
Definition
pressures may be falsely _______ in obese pts, and a proximal thigh pressure may be ______ in extremely thin pts.
Term
segmental
Definition
pulse volume recordings measure changes in ______ limb volume with each cardiac cyle.
Term
increase; decrease
Definition
in a normal individual without occlusive arterial disease, blood flow will ______ with exercise because of a ______ in peripheral vascular resistance.
Term
  • symptomatic cardiac disease
  • severe pulmonary disease
  • severe hypertension
  • inability to walk on the treadmill
  • cases of calcified vessels 
Definition
contraindications to lower-extremity arterial  stress testing
Term
healing
Definition
indirect arterial testing is helpful in predicting the likelihood of the ______ of skin lesions.
Term
hemodynamics
Definition
arterial duplex imaging provides direct anatomic physiologic information, but it does not provide information regarding overall limb ________.
Term
occlusion; patency; pseudoaneurysms
Definition
duplex imaging distinguishes between a stenosis and an ______, determines the length of the disease segment and ________ of the distal vessels, evaluates the results of intervenion (angioplasty, stent placement), aids in diagnoses of aneurysms and ______, and monitors patients' postoperative course with continuing bypass graft surveillance.
Term
60

Term
forward; reversal
Definition
the aortic characteristic waveform as a high-velocity _____ flow component during systole (venticular contraction), followed by a brief _____ of flow in early diastole (because of peripheral resistance), and a final low-velocity forward flow phase in late diastole (elastic recoil of the vessel wall).
Term
decreases
Definition
peak systolic velocity gradually _____ from the proximal to the distal arteries
Term

Term
neck
Definition
identification of the ____ of the pseudoaneurysm is important when ultrasound-guided compression therapy is attempted and color doppler imaging permits identification of the vessel of origin, which is important when planning surgincal interventions.
