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 ANSWER:
Subclavien and Internal jugular vein
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.
Celiac artery supplies blood to what organs?
CORRECT ANSWER:
Stomach, liver, pancreas, duodenum, and spleen.
Celiac artery branches into?
CORRECT ANSWER:
, Left gastric, splenic, common hepatic arteries.
SMA supplies blood to what organs?
CORRECT ANSWER:
Small intestine, cecum, ascending colon, part of transverse colon.
SMA location?
CORRECT ANSWER:
1cm distal to celiac artery.
IMA supplies what organs?
CORRECT ANSWER:
Left half of transverse colon, the descending, iliac, and sigmoid
colon, and part of rectum
IMA arises from?
CORRECT ANSWER:
Distal abdominal aorta 3-4cm above aortic bifurcation and can act as
a collateral connection.
May-Thurner syndrome
CORRECT ANSWER:
Compression of left common iliac vein by the right common iliac
artery as the artery crosses over it, increases likelihood of left
common iliac deep vein thrombosis.
Paget-Schroetter syndrome
CORRECT ANSWER:
-(Stress or effort thrombosis) thrombosis of subclavien or axillary
vein secondary to intense, repetitive activity.
-Associated with motion of upper extremity as seen with heavy lifting
or strenuous throwing of a baseball or football.
