  1. Virchow's Triad
    • Circulatory Stasis
    • Endothelial Injury

  2. The following are risk factors for _____
    Surgery
    Trauma
    Immobility
    Pregnancy
    Hypercoaguability/Blood disorders
    Oral Contraceptives
    Cancer

    Cardiac Disease
    *****Prior Hx*****
    DVT
  3. Symptoms of DVT
    • Extremity swelling/edema
    • Pain/Tightness
    • Positive Homan's sign
    • Asymptomatic
    • Chest Pain -- PE
  4. DVT Therapy
    • Bed Rest & Anticoagulants (Hearin, Coumadin. Compression Stockings)
    • Hospitalization & Anticoagulant IV Therapy
    • Percutaneous Catheter Thombolysis
    • IVC filter (If chronic PE)
  5. Perforators
    • Hunterian (prox thigh)
    • Dodd (distal thigh
    • Boyd's (around the knee)
    • Cockett's (of the posterior arch vein)
  6. The seven branches off the axillary artery:
    • Superior Artery
    • Thoracic Artery
    • Thoracocromial Artery
    • Lateral thoracic Artery
    • Subscapular Artery
    • Anterior and posterior humeral Artery
    • Thoracodorsal Artery
  7. 1st branch of the aortic arch:
    The Rt Innominate Artery
  8. LE Venous return regulated by:
    • Calf Muscle Contraction
    • Respiration
    • Valve sufficiency
    • Heart function

    One system not functioning=venous congestion
  9. Venous Insufficiency/Venous Incompetence

    Primary:
    Congenital absence or defect of valves
  10. Venous insufficiency/Venous Incompetence

    Secondary
    Post-phlebitic valves damaged by venous thrombosis, and/or chronic outflow obstruction
  11. Criteria for Venous Thrombosis
    • Absence of vein compressibility
    • Visualization of thrombus
    • Vein distention
    • Abnormal doppler signals
    • Reduced/absent augmentation
    • Reduced/absent color filling
  12. Acute DVT
    • Anechoic - fresh
    • Hypoechoic - hardening
    • Hyperechoic - hard
    • Hypoechoic - body is fighting it and liquifying it
    • Anechoic - liquid so body can fight it
  13. Chronic DVT
    • Echogenic thrombus
    • Vein smaller than artery
    • Presence of collaterals
    • Recannalization
    • Phleboliths
  14. Lt CCA branches directly off of:
    Aortic Arch
  15. Rt CCA branches from:
    Innominate Artery, along with the Rt Subclavian artery
  16. At the level of the _________, the CCA bifurcates into the ICA and ECA.
    thyroid cartilage
