Trans-Cervical Endovascular Management of Saccular Aneurysm of the Extracranial Internal Carotid Artery Using a Self-Expanding Nitinol Base ePTFE Covered Stent

Abstract

Saccular aneurysm of the extracranial internal carotid artery is rare. We present a 56-year-old lady presented with a progressively enlarging pulsatile swelling over the right neck, and the right internal carotid artery aneurysm was successfully treated with trans-carotid endovascular stenting of right common to right carotid artery using a self-expanding nitinol base ePTFE covered stent (COVERA Plus™ stent, Bard, Tempe, USA). The external carotid artery was prophylactically embolised to prevent back bleeding. New generation covered stents have consistently improved flexibility and conformability, and this is to our knowledge the first reported case in the world’s literature of using this type of self-expanding nitinol base ePTFE covered stent in endovascular stenting of carotid artery aneurysms, with excellent short-term results.
