3 causes of venous thrombosis also called, Virchow's Triad Venous stasis,
trauma/endothelial damage, hypercoagulability
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.
2 types of Trauma/endothelial damage Intrinsic and extrinsic
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.
Extrinsic trauma is Damage caused by an accident, which can occur at any site of the body.
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
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
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
, 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
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
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
