|
|
|
20% of ______________ recanalize completely
|
iliofemoral thromboses
* Recanalize to form a normal, unobstructed lumen |

|
|
T or F:
Collaterals are new vessels that the body makes |

It is not a true surgical procedure |
|
|
What are the disadvantages of Thrombolysis?
|
- Thrombolysis often takes 24-48 HR to complete

|
- Recurrent DVT or PE despite anticoagulation
- Documented DVT or PE w/a contradiction to anticoagulation - Pts w/complications of anticoagulation requiring therapy to anticoagulation - Presence of a IFVT free-floating tail - Prophylactic placement in trauma pts who are at high risk for PE - In pregnant women w/DVT or PE instead of/with anticoagulation |
|
|
Where is the filter typically placed?
|
The R CFV
|
|
|
How it the filter normally deployed?
|
By cath
|
|
|

|
|
|
T or F:
IVC filters are permanent or temporary internationally |
FALSE:
Temporary filters are not approvd in U.S. |
|
|
Why does the body not reject the filter?
|
Metal of the device has an anticoagulant affect so that the body doesn't reject it
