Outcomes for overlapping stents in the extracranial carotid artery

Various diseases of the carotid artery are treatable by stenting. However, few reports of overlapping carotid stents exist.

Description
Summary:Various diseases of the carotid artery are treatable by stenting. However, few reports of overlapping carotid stents exist. As a result, the indications, long‐term outcomes, and potential complications of this technique remain largely unknown. We therefore present and examine a series of 11 patients treated by this unique stenting method. A retrospective single‐institution review was performed for patients in whom overlapping carotid stents were placed. Only patients with imaging follow‐up beyond 3 months were included. Of 38 patients who had extracranial carotid artery stents placed, 11 patients fulfilled the inclusion criteria for both overlapping stents and imaging follow‐up greater than 3 months (range, 0.4–3 years; mean, 1.3 years). Clinical follow‐up ranged between 0.4 and 3.6 years (mean, 2.1 years). Carotid pathology within this cohort included atheromatous stenosis (n = 3), recurrent stenosis following carotid endarterectomy (n = 2) or stenting (n = 1), postirradiation angiitis (n = 1), carotid artery kink created by initial stent placement (n = 2), and both traumatic (n = 1) and neoplastic (n = 1) carotid blowout syndrome. No permanent stroke or stenting‐related death occurred. Focal stenosis or intimal hyperplasia resulting in 35% or less luminal narrowing developed in three patients (27%) after tandem stenting. Overlapping stents provide a durable treatment for a variety of extracranial carotid pathologies. Clinically and hemodynamically significant (> 50%) poststenting stenosis or intimal hyperplasia did not occur in this series. Catheter Cardiovasc Interv 2004;62:375–379. © 2004 Wiley‐Liss, Inc.
