Venothromboembolism Flashcards
DVT Locations
Proximal: worse, closer to bigger vessels
-popliteal & sup femoral (MC), proximal veins
Distal: smaller vessels
-Calf DVT extends proximally 30%
Proximal Deep Vein Thrombosis
-PDVT
-most dangerous lower extremity because it can move
Role of PT in DVT
Prevention:
-mobility, screen risk, education, compression, know signs, recommend testing
Post-DVT:
compression, verify anticoagulants, mobility, consult with team, screen for fall risk
Test Risk of DVT
-Pauda Prediction Score
-Pt history and risk factors
Test of Having DVT
-Wells DVT
-probablity of DVT
-Current symptoms
Lab Test to Determine DVT
D-Dimer Test:
-reflects amount of degradation of a clot
-followed by ultra sound
PT Prothrombin Time:
-time it takes to clot, prothrombin to thrombin
->25 high risk for bleeding
PTT Partial Thromboplastin Time:
-22-32s
-heparin makes the value 2x higher
V/Q Scan:
-diagnose PE
-air is white and bad
-black is good and perfused
Inferior Vena Cava Filter
-filter in IVC to catch blood cloths
