NO
We will clarify an effectiveness of routine use of debris aspiration before retrieval of filter protection devices in carotid arterial stenting.
Then, we will examine the debris captured by filter device and aspiration.

Published
The captured debris appeared to originate from atheromatous plaques. If the routine aspiration method had not been used in the present series, the debris might have migrated into intracerebral arteries. Restriction of the extension of a proximal ICA angulation might reduce the amount of debris associated with CAS, especially when the proximal ICA angulation is pronounced.
