Thoracoabdominal aortic aneurysm (TAAA) is a life-threatening condition with a potentially high risk of rupture (46% to 74%) when left untreated. Mean elective surgical mortality rate is 6.6% at best, rising to 47% for emergency operations. Standard thoracic endovascular repair alone is not currently considered an adequate approach to treat TAAA because of the visceral arteries involved by the aneurysm sac. ⋯ Three transient renal function impairments (20%) and one type III endoleak (11%), which sealed spontaneously at the 1-month assessment, were detected. Sandwich technique for TAAA repair is a safe, well-tolerated, feasible alternative using ready-to-use endoprosthesis to provide efficient visceral revascularization in types I, II, III, and IV TAAAs. The sandwich technique appears to be a promising tool in the endovascular repair of TAAA, but more experience with the method is warranted.
