OBJECTIVE: The purpose of this study was to
report the authors' preliminary experience using the Amplatzer Vascular Plug (AVP) (St. Jude Medical, Plymouth, MN, USA) for
parent artery occlusion of the
internal carotid artery (ICA) or
vertebral artery (VA). MATERIALS AND
METHODS: Between September 2008 and December 2015, we performed 52
therapeutic parent artery occlusions (PAOs) by an
endovascular technique . Among them, 10
patients underwent PAO of the carotid or
vertebral arteries using AVPs. Clinical and radiographic data of these
patients were retrospectively reviewed.
RESULTS: The
devices were used for VA
dissection that presented with
subarachnoid hemorrhage (SAH) in five
patients , traumatic
arteriovenous fistula (AVF) in two
patients , spontaneous AVF in one
patient ,
recurrence of carotid-cavernous
fistula (CCF) in one
patient , and symptomatic unruptured giant ICA
aneurysm in one
patient . The
devices were used in conjunction with detachable and/or pushable coils and in the extracranial segments of the ICA or VA. Complete occlusion of the
parent artery was achieved in all
patients . There was one intra-procedural
rupture of the VA
dissection during coiling prior to using the
device .
CONCLUSION: Results from the current series suggest that the AVP might be used for
therapeutic PAO in the extracranial segments of the ICA or VA.
