Feasibility of Three-Dimensional MR Angiography Image Fusion Guidance for Endovascular Abdominal Aortic Aneurysm Repair.

Magnetic resonance (MR) angiography image fusion (IF) with live fluoroscopy guidance was used while performing endovascular repair of abdominal aortic aneurysm (EVAR) in five patients with a history of chronic renal disease or severe contrast allergy. Intraprocedural technical success was 100%. Median procedure time was 120 minutes (range, 60-180 min), fluoroscopy time was 40 minutes (range, 17-65 min), dose-area product was 245,867 mGy × cm(2) (range, 68,435-690,053 mGy × cm(2)), and iodinated contrast volume injected was 15 mL (range, 0-40 mL).

Image fusion for hybrid repair of dislocated superior mesenteric branch of a branched endovascular aortic graft.

Recent advances in imaging technology allow the projection of volumetric imaging data from the preacquired computed tomography angiography over live fluoroscopy during interventions. This "fusion" technology is currently underused, although its application carries distinct advantages. We introduce a case in which fusion technology was used for the placement of two thoracic and one branched abdominal aortic endograft and to treat late dislocation of its side branch using a hybrid technique.

Management of perioperative endoleaks during endovascular treatment of juxta-renal aneurysms.

Background: Evolution of stentgraft and vascular imaging technologies allows endovascular treatment (ET) of juxta-renal aneurysms (JRA). However, endoleaks rates and implants stability are not well documented. The aim of this study was to report the incidence and the perioperative treatment of the endoleaks occurring during ET for JRA.
