Renal Fenestration Closure Technique in Fenestrated Endovascular Repair for Pararenal Aortic Aneurysm.
Annals of Vascular Surgery 2018 May
PURPOSE: To describe an endovascular technique to close a renal artery fenestration during fenestrated endograft implant for a pararenal abdominal aortic aneurysm (p-AAA) without interfering with other visceral vessels.
REPORT: A 76-year-old man with p-AAA underwent repair by a 4 fenestrations custom-made endograft. At the intraprocedural angiography, the right renal artery was occluded. To avoid a high-flow endoleak from fenestration, we performed the following technique: a 9F-steerable sheath was used to advance a 7F sheath through the fenestration into aneurism. A balloon-expandable covered stent was deployed across the fenestration and then occluded by 2 vascular plugs. At the completion angiography, there was no endoleak from the right renal fenestration, and at 6-month period, p-AAA remained completely excluded.
CONCLUSIONS: The present technique can be a safe and effective therapeutic option to propose in cases of impossible target visceral vessels cannulation during p-AAA repair using a custom-made device to avoid the aneurysmal sac perfusion.
