QUESTIONS AND ANSWERS
3 causes of venous thrombosis also called, Virchow's Triad. ANSWER - Venous stasis,
trauma/endothelial damage, hypercoagulability
Venous stasis. ANSWER - 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.
2 types of Trauma/endothelial damage. ANSWER - Intrinsic and extrinsic
Intrinsic trauma is. ANSWER - 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.
Extrinsic trauma is. ANSWER - Damage caused by an accident, which can occur at any site
of the body.
Hypercoagulability is associated with. ANSWER - 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
Sensitivity, and
How to calculate?. ANSWER - -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
Specificity, and how to calculate?. ANSWER - -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
Positive predictive value, and how to calculate?. ANSWER - -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
Negative predictive value, and how to calculate?. ANSWER - - 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
Accuracy, and how to calculate?. ANSWER - - % 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
Brachiocephalic/ Innominate vien formed from confluence of?. ANSWER - Subclavien and
Internal jugular vein

young women more common.
FMD- younger women.
