"Over-SIRIX". A new method for sizing aortic endografts in combination with the chimney grafts. early experience with aortic arch disease

Abstract
BACKGROUND:

Large gutters after chimney procedures are one of the main causes of type I endoleak (EL-I). This study aims to evaluate a new tailored planning named "Over-SIRIX," based on Osirix Imaging Software, to choose the correct main graft oversizing in order to minimize EL-I incidence.
METHODS:

A double nellix and chimney covered stents: challenging treatment of pararenal aortic aneurysm

A 77-year-old male patient presented with a symptomatic, 66-mm pararenal aortic aneurysm. The patient was classified as unsuitable for open surgery due to significant comorbidities. Fenestrated or branched endografts were contraindicated due to the poor iliac access (6 mm diameter). A double Nellix with chimney endovascular aneurysm sealing (ChEVAS) technique was selected to exclude the pararenal aortic aneurysm and to preserve renal arteries and the superior mesenteric artery.
