Internal Carotid Artery Pseudoaneurysms: Treatment With the Wallgraft Endoprosthesis

Abstract

The thin-walled fabric of the Wallgraft appears capable of completely excluding the pseudoaneurysm, resulting in decreased aneurysm size over time.

Placement of Covered Stents for Carotid Blowout in Patients with Head and Neck Cancer: Follow-up Results after Rescue Treatments

“…There have been several reports of the successful application of covered stents for the treatment of a leaking artery. [6][7][8][9][10][11][12][13] Our previous experience with covered stents also coincided with other positive reports.…”

Endovascular Treatment of Carotid and Vertebral Pseudoaneurysms with Covered Stents

“…14 Duane et al 15 describe the 2-year patency of a covered stent placed in the right ICA for traumatic pseudoaneurysm on daily ASA alone, whereas a covered stent in another patient of theirs was occluded at 6 weeks on ASA therapy. Kubaska et al 16 describe a 2-year patency of a covered stent placed in the left ICA for traumatic pseudoaneurysm after being treated with ASA and clopidogrel for just 30 days.OnecasereportdescribesaWallgraft(BostonScientific,Natick, Mass) covered stent placed in the carotid bulb for delayed pseudoaneurysm following CEA to be occluded at 12 months despite 6 weeks of clopidogrel followed by continued ASA. 13 We used varying anticoagulation/antiplatelet regimens due to the supposed risk of hemorrhage from the pseudoaneurysm or the other severe injuries.…”

Treatment of a Recurrent Internal Carotid Artery Pseudoaneurysm with the Wallgraft Endoprosthesis

“…To the best of our knowledge there have been seven reports describing the use of the Wallgraft prosthesis for the treatment of carotid artery pseudoaneurysms of varying aetiologies in a total of 14 patients [4][5][6][7][8]16,17 . Clinical follow up was performed in all patients and ranged from one month to two years.…”

“…In recent years there have been a number of reports describing the use of endovascular techniques for the treatment of traumatic carotid artery pseudoaneurysms [1][2][3][4][5][6][7][8] . Covered stents have gained interest due to their ability to completely obliterate the aneurysm whilst maintaining patency of the parent vessel.…”
