Neck-Targeted, Stand-Alone Coiling for Successful Treatment of Type 1A Endoleak Following Endovascular Repair

Abstract

Endovascular repair is a standard of treatment for patients with abdominal aortic aneurysm who are unfit for open surgery. Type 1A endoleak (T1A-E) is defined as persistent blood flow outside the lumen of the endograft due to a failure of the graft to seal the proximal landing zone adequately. Accordingly, T1A-E treatment is mandatory, and endovascular options, when possible, consist of standard adjuncts as cuffs and stents or sometimes mere ballooning. Alternatively, different embolization techniques have been described in little or case series. We describe a successful management of large T1A-E with solely coil embolization of the isolated leakage area.
