Blood Vessels - Coggle Diagram

- - - - redness
      - thickening
      - tenderness
  - - - deep vein obstruction
      - valvular incompetence
- - - - Subjective: >50 YO, flu-like symptoms, headache in temporal region, ocular symptoms (loss of vision), tongue pain, jaw claudication
      - Objecive: area over temporal artery may be red, swollen; temporal pulse may be strong, weak, or absent
    - - Four times more common in men than women
      - Subjective: asymptomatic until they dissect or compress adjacent structures
      - Objective: Pulsatile swelling, thrill or bruit over aneurysm
    - - Subjective: lower extremety edema, varicose veins, claudication
      - Objective: continuous bruit or thrill, edema or ischemia
    - - Subjective: pain with exercise, relieved by rest
      - Objective: limb appears healthy, but pulses are weak; progressive stenosis= ischemia, cold, numb
    - - Subjective: involved areas are cold/achy
      - Objective: triphasic demarcated skin pallor (white), cyanosis (blue), and reperfusion (red) in extremities. Lasts from minutes to hour
    - - Subjective: pain most common symptom, paresthesias
      - Objective: necrosis of tissue (blue toe syndrome); splinter hemorrhages in nail beds
  - - - Subjective: mild-asymptomatic; severe- hypertension or vascular insufficiency, failure to thrive
      - Objective: differences in systolic bp between arms and legs, femoral pulses <radial pulses
    - - Subjective: diffuse; fever >5 days, myalgias, weight loss
      - Objective: conjunctival infection, strawberry tongue, edema hands/feet, lymphadenopathy, rash
- - - - 4: bounding, aneurysmal
      - 3: full, increased
      - 2: expected
      - 1: diminished
      - 0: absent
  - - - brachial, radial, femoral pulse easily palpable
      - Bounding pulse may = left-to-right shunt (PDA)
      - If pulse amplitude is greater in upper extrem vs lower extrem = coarctation of aorta
    - - HTN present in 1-3% of children (can signal kidney dx, coarctation, pheochromocytoma)
      - Venous thrombosis less common
    - - BP falls until 16-20 weeks
      - Sustained systolic pressure >140 may = PIH
- - - - Calf muscle: superficial femoral artery
      - Thigh: common femoral artery or external iliac artery
      - Buttock: common iliac artery or distal aorta
- - - - Systemic vascular resistance decreases
      - Peripheral vasodilation occurs
    - - hypoension
      - dependent edema
      - Variscosities in legs/vulva
      - hemorrhoids
