solutions
3 causes of venous thrombosis also called, Virchow's Triad - correct answer✔✔Venous
|| || || || || || || || || || || ||
stasis, trauma/endothelial damage, hypercoagulability
|| || ||
Venous stasis - correct 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 - correct answer✔✔Intrinsic and extrinsic
|| || || || || || || || ||
Intrinsic trauma is - correct 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 - correct answer✔✔Damage caused by an accident, which can occur at
|| || || || || || || || || || || || || ||
any site of the body.
|| || || ||
Hypercoagulability is associated with - correct 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? - correct 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? - correct 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? - correct 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? - correct 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? - correct 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? - correct || || || || || || || || ||

Vascular disease more common in women? - correct answer✔✔Takayasu's arteritis-tennage
|| || || || || || || || || ||
to young women more common.
|| || || ||
FMD- younger women. || ||
Celiac band syndrome- young athletic women.
|| || || || ||
Vascular disease more common in men? - correct answer✔✔Obliteritis angitis(bergers
|| || || || || || || || || ||
disease)- younger <40 men, heavy smokers. || || || || ||
Popliteal artery entrapment syndrome- young athletic men.
