Q

Blood Flow in The Arterial & Venous System depends on?

A disturbance disrupts?
3

A

Depends on a system of

  1. patent blood vessels and
  2. adequate perfusion pressure

A disturbance disrupts:

  1. The delivery of oxygen and nutrients
  2. The removal of waste products
  3. The return of blood to the heart

PAD is occlusive arterial disease primarily of the lower extremities 2. 250% 3. - Aortic bifurcation - Tibial trifurcation - Femoral artery at adductor hiatus
60
PAD occurs when: 1. MOst commonly 2. Where else can it develop
1. Most commonly seen when the arteries of your legs become hardened and clogged and reduce the flow of blood to your legs and feet. 2. However, PAD can also develop in the arteries that carry blood from your heart to your head, arms, kidneys and stomach Just like clogged arteries in your heart, clogged arteries in your legs raises your risk for having a heart attack or stroke.
61
PAD can affect your quality of life: How so? How can you help this?
Nearly everyone who has P.A.D, even those that do not report leg symptoms suffers from an impaired ability to walk as fast or as far as they could with P.A.D. will build collaterals for exercise so when we reperfuse them they have to exercise
62
1. What does PAD result in? | 2. Peripheral arterial disease may be described as what two kinds?
1. Peripheral arterial disease results in reduced blood flow in the arteries of the trunk, arms and legs 2. Occulsive or Functional
63
1. Occlusive PAD is due to? 2. Functional PAD is due to? 3. There is also Raynaud’s disease which is a condition in which are?
1. Occlusive PAD is due to structural changes that narrow or block arteries and often results from atherosclerosis 2. Functional is usually due to a sudden, temporary narrowing (spasm) 3. small arteries (arterioles), usually in fingers or toes, constrict more tightly in response to cold or stress Distinct syndrome and is NOT ALWAYS due to PAD
64
Three distinct patterns of disease 1. Type I: affects 10-15% of patients? 2 Most common in younger pts? 2. Type II: affects 25% of patients? - afeects what? 3. Type III: most common (60-70% of patients)? - What kind of disease? - Affects what? 5

78
Classification by the size of vessel - Large vessel? 2 - Medium vessel? 3 - Small vessel? 2
1. Takayaus arteritis, 2. Temporal arteritis 1. Buerger’s disease, 2. Kawasaki disease, 3. Polyarteritis nodosa 1. Henoch-Schonlein purpura, 2. Behcets syndrome

Possible Vasculitis Symptoms | 8
1. General symptoms: Fever, weight loss 2. Skin: Palpable purpura 3. Muscle and joints: Myalgia, arthralgia or arthritis 4. Nervous system: headache, stroke, tinnitus, reduced visual acuities 5. Heart and arteries: MI, HTN, gangrene 6. Respiratory tract: Nose bleeds, bloody cough, lung infiltrates 7. GI tract: Abdominal pain, bloody stool, perforations 8. Kidneys: Glomerulonephritis
80
Vasculitis Diagnosis | 6
1. ESR 2. CRP 3. Anemia 4. Increased WBC and eosinophilia 5. Biopsy of involved organ or tissue is definitive 6. Angiogram as an alternate to biopsy
81
Vasculitis Treatment? | 3
1. Corticosteroids (Prednisone) 2. Possibly immune suppression drugs 3. Possibly antibiotics
82
IN what diseases will your ESR and SED levels be elevated? | 3
1. infection, 2. cancer, 3. rheum diseases
83
1. What is Giant – Cell Arteritis Temporal Arteritis? 2. Whats the most serious complication? 3. Woman >men by a ratio of 2:1 Presentation? 9
Inflammatory disease of blood vessels most commonly involving large and medium arteries of the head predominantly the external carotid artery. Most serious complication is permanent blindness 1. Bruits 2. Fever 3. Headache 4. Sensitivity of the scalp 5. Jaw claudication 6. Tongue claudication 7. Acute visual loss or reduced visual acuity 8. Diplopia (double vision) 9. Acute tinnitus
84
How would we start treating temporal arteritis? | 3
1. SED 2. IV steriods high dose (Treatment is high dose prednisone to prevent blindness) prevent blindness 3. Biopsy at the end of that maybe
85
Giant – Cell Arteritis Temporal Arteritis PE? 4 Labs? 4 Gold standard for diagnosis?
1. Palpation of the head reveals prominent temporal arteries with or without pulsation 2. Temporal area may be tender 3. Decreased pulses may be found through out the body 4. Evidence of ischemia may be noted on fundal exam 1. LFT’s, increased ALP- alkaline phosphatase 2. ESR can be >60 3. CRP commonly elevated 4. Platelets may be elevated Biopsy
