The vascular plug: a new device for parent artery occlusion.

摘要

We read with great interest the article by Drs Ross and Buciuc1 in which they reported their experience with using the Amplatzer vascular plug for parent artery occlusion to treat a large aneurysm of the cavernous internal carotid artery. We would like to raise an issue of possible concern, which was a central point of our recent publication on this topic.2 Although we certainly agree with the authors that coil migration and distal coil embolization is a risk of parent vessel occlusion with use of detachable coils, we advocate that the current generation of the Amplatzer vascular plug be used as an adjunct to coil occlusion rather than as a stand-alone device. The Amplatzer plug used in both studies is porous, and is, accordingly, insufficient to seal flow through the vessel in a patient, on anticoagulant and antiplatelet therapy.
