1. 2, 3, 4, |
platelet count
bleeding time inr APTT |
|
|
This diagnostic study is a determination of venous flow in deep femoral, popiteal and pesterior tibial veins
|
a venous doppler evaluation
|
|
|
the normal finding of spontaneous flow with variation transmitted by respiration cycle, tell me what the abnormal finding would be using this doppler
|
absence of flow augmentation with distal compression and proximal release
|
|
|
this is a combination of ultrasound imaging techniques and doppler capabilitis to determine location and extent of thrombus within veins
|
Duplex scanning
|
|
|
Duplex scanning is most widely used to test for what disorder
|
DVT
|
|
|
This is a X-ray determination of location and extent of clot using ontrast media to outline filling defects; development of collateral circulation defined
|
venogram (phlebogram)
|
|
|
this is used in means of determining the presence of pulmonary embolism and extent of resulting lung damage, abnormal findings of mismatch between ventilation and perfusion componenets; frequently inconclusive
|
lung scan
|
|
|
this is an x-ray that determines by using contrast media the location and the size of a pulmonary embolism
|
pulmonary angiogram
|
|
|
This type of CT scan obtains continous slices allowing visualization of the entire anatomic areas such as the lung data can be computer resonstructed to allow for a 3-d picture
|
Spiral Ct scan
