The Dual Layer Casper Micromesh Stent: Taking Advantage of Flow-Diverting Capabilities for the Treatment of Extracranial Aneurysms and Pseudoaneurysms

(Microvention, Tustin, CA) is a low-profile closed cell stent with an increased mesh density and reduced pore size compared to commonly utilized stents in carotid artery procedures. We describe our preliminary experience from flow diversion in two iatrogenic ECAP with the Casper stent in a retrospective observational analysis of patients with extracranial aneurysms treated endovascularly with the Casper stent. Patients were followed for up to 6 months (clinical exam and imaging). According to the institutional review board, the current analysis did not require approval. All patients or their legal representatives gave informed consent.
