5. INTRODUCTION
 What’s Atherosclerosis??
 Is chronic progressive degenerative disease affect vascular wall.
 Atherosclerosis-Related Diseases??
 Atherosclerosis can affect any artery in the body. As a result,
different diseases may develop based on which arteries are affected.
Such as:
 Coronary Heart Diseases.
 Peripheral Artery Disease.
 Chronic Kidney Disease.

6. Q1) WHICH INVESTIGATION DO YOU
RECOMMEND TO EVALUATE
PERIPHERAL ARTERIAL DISEASE?
Q2) WHICH OTHER TESTS
WOULD YOU LIKE TO
PERFORM?

7. GENERAL INFORMATION ABOUT
P.A.D
 (P.A.D.) is atherosclerosis of the extremities (virtually always lower)
causing ischemia.
Medical
history
• Risk factor for P.A.D ( diabetes, smoking, older age, hypertension,
stroke).
• Symptoms (Weak or no pulses in the legs or feet, lower
temperature in one leg, decreased hair growth on the legs,
intermittent claudication symptoms).
Family
history
• Family history of heart and blood vessels diseases.
• Father had MI (58y), mother had stroke (75y).
Physical
examination
• Checking pulses by stethoscope (weak or absent pulses in legs or
feet),
• Lower temperature in one leg, atrophic leg or feet.

8. INVESTIGATION OF P.A.D
 Ankle-Brachial Index (ABI):
• It compares blood pressure in the ankle to blood pressure in the
arm.
• This test shows how well blood is flowing in limbs.
• A normal ABI ( range between 0.90 - 1.30).
• Can be classified as:
• Mild (0.71 to 0.90),
• Moderate (0.41 to 0.70), or severe (≤ 0.40).
• The test takes about 10 to 15 minutes.

9. CON..
 Doppler Ultrasound:
• Looks at blood flow in the major arteries and veins.
• Handheld device is placed on:
• UE: over the axillary, brachial, ulnar, and radial arteries.
• LE: over the femoral, popliteal, dorsalis pedis, and
posterior tibial arteries.
• A computer converts sound waves into a picture of blood
flow in the arteries and veins.
• Provides details of the location and extent of arterial
stenoses or occlusion

10. CON..
Treadmill Test:
• The patient walks on a treadmill while the BP and EKG are
mentored
• A treadmill test can show the severity of symptoms and the
level of exercise.
Magnetic Resonance Angiogram (MRA):
• Uses magnetic and radio wave energy to take pictures of blood
vessels.
• Provides details of the location and extent of arterial stenosis or
occlusion.

11. CON…
 Arteriogram:
• Provides a "road map" of the arteries.
• Dye is injected through a needle into one of arteries. After that an x ray
is taken.
• it show the location, type, and extent of the blockage in the artery.
• tiny ultrasound camera to take picture (Intravascular ultrasound).
 Computed tomography (CT):
• can be of use to the emergency physician in that it does not have the
time.

12. CON…
Transcutaneous oximetry:
• Is a local, non-invasive measurement reflecting the amount of
O2 that has diffused from the capillaries, through the epidermis.
Electrocardiogram (ECG):
• Used to look for evidence of dysrhythmia, prior cardiac injury, or
even acute myocardial infarction.

13. CON…
 Laboratory studies:
• Complete blood count (CBC).
• Blood urea nitrogen (BUN).
• Creatinine.
• Electrolyte studies.
• Lipid profile.
• Coagulation tests.
• blood glucose test

14. Q1) Name 2 tests that we can use in the investigation of P.A.D??
QUIZ TIME !

15. Q3/HOW WOULD YOU TREAT THE
COMPLAINTS OF THIS PATIENT
WITH P.A.D?
Q4/WHAT OTHER MEDICAL
TREATMENTS SHOULD THIS
PATIENT RECEIVE?

16. TREATMENT OF P.A.D
 Risk factor modification.
 Exercise.
 Antiplatelet drugs.
 Sometimes pentoxifylline or cilostazol for claudication.
 Cholesterol lowering medication.
 ACE inhibitors.
 PTA or surgery for severe disease.

17. TREATMENT OF P.A.D
 Risk factor modification, include:
• Smoking cessation.
• Control of diabetes: Metformin 500mg twice daily.
• Control of HT: hydrochlorothiazide 25 mg once daily. (ACE).
• Dietary changes:
Less saturated fat<20 g/day.
More fruits and vegetables.
More fiber (decrease LDL 5%).
Eat fish (EPA  inhibit platelet aggregation).
Eat less red meat (homocystin).

18. TREATMENT OF P.A.D
 Exercise:
• 35 to 50 min of treadmill or track walking 3 to 4 times/wk. (with
underused treatment).
• Mechanisms:
• Increased collateral circulation.
• Improved endothelial function with microvascular vasodilation.
• Decreased blood viscosity.
• Increase HDL.

19. CON..
Antiplatelet drugs:
• lessen symptoms, improve walking distance and modify
thermogenesis.
• Aspirin 81 to 162 mg taking by mouth, once/day. (low dose).
• Aspirin 25 mg plus dipyridamole 200 mg taking by mouth
once/day,
• Action of aspirin:
• Inhibit TXA2.
• Maintain activity of prostacyclin.

20. CON..
 To relief of claudication:
• Pentoxifylline 400 mg, taken by mouth, three time daily.
• or cilostazol 100 mg, taken by mouth, twice daily.
• Mechanisms:
• Relieve intermittent claudication by improving blood flow and
enhancing tissue oxygenation in affected areas.

21. CON…
ACE inhibitors:
• Ramipril 10 mg, taking by mouth once/day.
• Mechanisms:
• They are antiatherogenic.
• Promoting the degradation of bradykinin and the release of nitric oxide.

22. CON…
Cholesterol lowering medication:
• Statin.
• Indication:
• Total cholesterol above 3.5 mmol/L.

23. CON…
 Percutaneous transluminal intervention:
• Is a minimally invasive procedure to open up blocked arteries.
• Work best in large arteries with high flow (iliac and renal).
• They are less useful for smaller arteries and for long
occlusions.
• Indications:
• Intermittent claudication that inhibits daily activities.
• Rest pain.
• Gangrene.

24. CON…
 Surgery:
• Thromboendarterectomy: (surgical removal of an occlusive lesion).
• Revascularization: uses synthetic or natural materials (often the saphenous
or another vein) to bypass occlusive lesions.
• Amputation: is a procedure of last resort, indicated for uncontrolled
infection, unrelenting rest pain, and progressive gangrene.

25. SUMMARY
Atherosclerosis Is chronic progressive degenerative disease affect
vascular wall.
Atherosclerosis can associated with other disease like P.A.D.
General information about P.A.D.
Investigation.
Treatment.

26. QUIZ TIME !
Q1) to treat P.A.D and Atherosclerosis we used:
