1. 3 causes of venous thrombosis also called, Virchow's Triad: Venous stasis,
trauma/endothelial damage, hypercoagulability
2. Venous stasis: Slowed blood flow in veins. Caused by immobility, myocardial
infarction, CHF, hypotension, COPD, obesity, pregnancy, previous DVT, extrinsic
compression, SVC syndrome, paraplegia, surgery associated conditions.
3. 2 types of Trauma/endothelial damage: Intrinsic and extrinsic
4. Intrinsic trauma is: Damage to the vessel wall from intravenous drugs or a
catheter. Increased use of PICC line results in higher incidence of upper extremity
thrombus, usually developing at most proximal portion of PICC line.
5. Extrinsic trauma is: Damage caused by an accident, which can occur at any site of
the body.
6. Hypercoagulability is associated with: Pregnancy, cancer, oral contraceptives
and/or hormone replacement therapy, inherited states,e.g., factor V Leiden or protein C,
protein S, or Antithrombin III deficiency
7. Sensitivity, and
How to calculate?: -Ability of a test to detect disease, how many tests are correctly
called positive.
- # of true positives divided by # of all positive tests by gold standard, or TP/TP+FN
8. Specificity, and how to calculate?: -Ability of a test to identify normality, or how
many results were correctly called negative.

, - # of true negative divided by # of all negative tests by gold standard, or TN/TN+FP
9. Positive predictive value, and how to calculate?: -percentage of test results
that accurately predict abnormality, or what % correctly predicted disease.
- # of true positive test divided by # of all positive tests, or TP/TP+FP
10. Negative predictive value, and how to calculate?: - percentage of test results
that accurately predict normality, or what % correctly predicted absence of disease.
- # of true negatives divided by # of all negative tests, or TN/TN+FN
11. Accuracy, and how to calculate?: - % of correct tests, or how well does the test
both detect and rule out disease.
- total # of correct tests divided by total # of all tests, or TP+TN/TP+FP+FN+TN
12. Brachiocephalic/ Innominate vien formed from confluence of?: Subclavien
and Internal jugular vein
13. Vascular disease more common in women?: Takayasu's arteritis-tennage to
young women more common.
FMD- younger women.
Celiac band syndrome- young athletic women.
14. Vascular disease more common in men?: Obliteritis angitis(bergers disease)-
younger <40 men, heavy smokers.
Popliteal artery entrapment syndrome- young athletic men.
