Answer to Question 1

ANS: B
The ideal filter should have the following characteristics: low cost, lifetime of device is not time limited, high filtration without flow interruption, low access site thrombosis, small caliber percutaneous insertion and deployment devices, repositioned or removed easily, secure fixation to the vessel wall, and MRI friendly (non-magnetic).

Answer to Question 2

ANS: A
A pseudoaneurysm is usually caused by a break in the integrity in the vessel wall and this causes all the layers of the vessel to separate and bulge. A pseudoaneurysm differs from true aneurysm because it is caused by an outside source rather than vascular pathology.
