PURPOSE: Thoracic endovascular aortic repair (TEVAR) is the preferred treatment of descending thoracic aorta pathology. However, TEVAR in the aortic arch remains challenging. Customized fenestrated TEVAR (fTEVAR) allows extension of the proximal seal zone, while preserving the involved supra-aortic vessels. There is a paucity of information on fTEVAR; hence, we aim to evaluate our early experience and lessons learnt with fTEVAR in the aortic arch. METHODS: This is a retrospective single-centre review of fTEVAR endografts for aortic arch pathology over 24 months...

The present report describes the management of massive proximal type 1 endoleak with an enlarged symptomatic aneurysmal sac. Urgent treatment was performed using in situ laser fenestration of an aortic proximal extension facing renovisceral ostia. Image fusion was obtained intraoperatively. For each target vessel (superior mesenteric and two renal arteries), an Aptus HeliFX steerable sheath (Medtronic) inserted through femoral access was curved to face the vessel's ostium marker. A laser catheter (Spectranetics) was used to traverse the stent-graft and insert a 0...

BACKGROUND: The technical and clinical success of the thoracic aortic endovascular procedures rests mainly on the choice of the proximal sealing zone (PSZ). The latter can be the affected by multiple complications, all of them having a potential gravity and a direct link with the quality of the PSZ. The objective of this study was to analyze the risk factors of the occurrence of complications of the PSZ. METHODS: Between 2007 and 2015, all the patients treated by a thoracic stentgraft in zones 2, 3, or 4 were retrospectively reviewed, with analysis of the pre- and postoperative angio-CT...

OBJECTIVE: Fenestrated endografts are customized, patient-specific endovascular devices with potential to reduce morbidity and mortality of complex aortic aneurysm repair. With approval from the U.S. Food and Drug Administration, our center began performing fenestrated endovascular aneurysm repair through a physician-sponsored investigational device exemption (IDE #G130210), using both physician-modified endografts (PMEGs) and company-manufactured devices (CMDs). Because these techniques are associated with specific advantages and disadvantages, we sought to investigate differences in outcomes between PMEG and CMD cases...

PURPOSE: To describe and validate a new methodology for visualizing and quantifying 3-dimensional (3D) displacement of the stent frames of the Nellix endosystem after endovascular aneurysm sealing (EVAS). METHODS: The 3D positions of the stent frames were registered to 5 fixed anatomical landmarks on the post-EVAS computed tomography (CT) scans, facilitating comparison of the position and shape of the stent frames between consecutive follow-up scans. Displacement of the proximal and distal ends of the stent frames, the entire stent frame trajectories, as well as changes in distance between the stent frames were determined for 6 patients with >5-mm displacement and 6 patients with <5-mm displacement at 1-year follow-up...

Herein, we report a rare case of type B aortic dissection that occurred after endovascular aortic aneurysm repair (EVAR). A 66-year-old man underwent successful EVAR for an abdominal aortic aneurysm (AAA). Computed tomography (CT) 2 years after EVAR showed a type B aortic dissection with stent-graft migration and AAA expansion. Juxtarenal aortic expansion precluded simple stent-graft placement. He underwent hepato-spleno-renal bypass followed by stent-graft placement just below the superior mesenteric artery...
