- Brief summaryRationale:
Juxta- and suprarenal abdominal aortic aneurysms (AAA) are traditionally treated by open repair. Fenestrated endovascular repair offers an alternative to open repair and has been associated with a lower mortality rate. The Anaconda endograft is effective and safe in treating infrarenal AAA.

Objective:
To analyse the safety and effectiveness of the fenestrated Anaconda endograft in treating juxta- and suprarenal AAA.

Study design:
Monocenter feasibility study of the fenestrated Anaconda endograft.

Study population:
Patients with juxta- and suprarenal AAA > 55mm.

Intervention:
Treating juxta- and suprarenal AAA with the fenestrated Anaconda endograft.

Main study parameters/endpoints:
Technical succes of excluding the AAA, patency migration and endoleak rates of the endograft, renal function, cardiopulmonary complications, mortality.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness:
The fenestrated Anaconda endograft has not yet been analyzed in treating juxta- and suprarenal AAA. There is a risk that this endograft is not able to effectively exclude these AAA. In such a case, it may be necessary to treat these AAA with open repair. Renal function deterioration has been described using fenestrated endografts. Overall, fenestrated endografts seem to have a lower morbidity and mortality rate compared to the open repair procedure, which is an obvious benefit for these patients.
