Disorder accompanied by a narrowing or an
occlusion of the intima and media of the blood
Plaque formation: as a result of the
arteriosclerotic process, form on the internal wall
of the blood vessels, causing partial or complete
occlusion of the blood vessel.
Result: is little or no blood flow to the affected
extremity. The artery is unable to supply blood
and oxygen to the tissue.
Pain is the first symptom that occurs in from tissue
Pain generally occurs in the affected extremity in
conjunction w/sustained activity. This is due to the
demand of the tissue exceeding the available blood
Claudication is the process of activity to ischemia to pain
in an affected extremity.
Symptoms are coldness, numbness, and tingling may be
Signs and symptoms to watch for are the 5 P’s pain,
pulslessness, pallor, paresthesia and paralysis.
Subjective data- focuses on pain associated with
Does the pain occur w/activity ?
Is it relived at rest ?
Or is the pain occurring at rest ?
Objective data- includes assessment of pulses in the
affected extremity, which may be weak or absent,
compare to unaffected extremity. Other assessment
factors may include pallor and hairless, shiny skin that is
dry and cool to touch, cyanosis, arterial ulcers, cellulitis,
or gangrenous changes in the affected extremity.
Treadmill testing- form of monitoring hearts capability.
The patient is put through a limit of exertion to evaluate
Digital subtraction angiography- is the procedure to
visualize blood vessels with contrast medium in a bony
environment by subtracting the pre-contrast image from
the image with contrast medium.
Doppler ultrasound- used to measure your blood
pressure at various points along your arms or legs.
These measurements can help your doctor gauge the
degree of any blockage, as well as the speed of blood
flow in your arteries.
MRI are also obtained.

sagittal (divides the body into sinister and dexter
(left and right) portions. ) cross section through a
Is focused on preventing complete arterial occlusion.
Frequently used medications are anticoagulants- used to prolong
clotting time (heparin and warfarin).
Fibrinolytics or thrombolitics are useful in dissolving existing thrombi
Surgery is used for advanced disease. Includes embolectomy (the
removal of embolism)
endolectomy (the surgical removal of the lining of an artery).
An arterial bypass operation is done to treat a blockage in a major
artery that is causing symptoms due to lack of sufficient blood flow.
Targeted, color-enhanced, 3D volume-rendering reconstruction of the distal
arterial bypass graft confirms the normal appearance of the distal anastomoses
(thin white arrows). Note postoperative clip material (white arrowheads) and
additional interposed short new graft segment (thick white arrow).
Related to ischemic pain or immobility.
Prevent hazards of immobility by turning
promote exercise for circulation
Nursing interventions continued
Ineffective tissue perfusion
Related to decreased arterial blood flow.
Avoid raising feet above heart,
keep extremities warm to promote
teach patient importance in not smoking to
also avoid caffeine or chilling.
Not crossing their legs
Not to wear constrictive cloths such as garters,
tight stockings, or belts.
