Early Experience with Snorkels and Chimneys for Expanding the Indications for Use of Endovascular Aneurysm Repair

Parallel stent-graft repair for paravisceral aneurysms is feasible and has acceptable technical/clinical success and complication rates. Although long-term follow-up is still needed, this technique fills the gap in endovascular options for poor open surgical candidates in whom fenestrated devices are not available.
