title: Glue embolus complicating the endovascular treatment of a patient with Loeys-Dietz syndrome.
abstract: A 34-year-old [corrected] woman was diagnosed with Loeys-Dietz syndrome. Five months later, the patient presented with a symptomatic 2.6-cm subclavian pseudoaneurysm. Staged endovascular treatment was initiated with left vertebral artery embolization, followed by sac ablation and stent graft exclusion. The pseudoaneurysm cavity was filled with n-butylcyanoacrylate ("glue") via a microcatheter. Despite balloon occlusion of the pseudoaneurysm orifice, a small amount of glue debris embolized to the brachial artery, necessitating a vein bypass. In this case, distal embolization of glue may have been avoided by leaving a microcatheter in the aneurysm sac for glue injection after first deploying the stent graft.
