Abstract
Large pseudoaneurysms which compress the parent vessel are challenging lesions to successfully treat with endovascular therapy. We describe the endovascular treatment of a giant extracranial carotid artery (ECCA) pseudoaneurysm resulting in substantial mass effect on the common carotid artery (CCA) bifurcation using a telescoping dual covered stent graft construct. A 56-year-old male was diagnosed with an 8.5 cm x 13 cm pseudoaneurysm arising from the left CCA bifurcation, which was causing luminal narrowing of the CCA and proximal internal carotid artery (ICA). The patient underwent endovascular intervention, during which a balloon-expandable covered stent was deployed within a heparin-bonded covered stent, such that the overall construct spanned from the CCA to the lower cervical ICA. The employment of a telescoping dual covered stent technique can successfully treat appropriately selected patients with large or giant ECCA pseudoaneurysms, with the concomitant goals of excluding the pseudoaneurysm and restoring the luminal caliber of the parent artery.
