To evaluate the performance of periscope and/or chimney grafts (CPGs) in the endovascular treatment of pararenal or thoracoabdominal aneurysms using off-the-shelf devices. ⋯ In this series, the use of CPGs has proven to be a feasible, safe, and effective way to treat thoracoabdominal and pararenal aneurysms with maintenance of blood flow to the renovisceral arteries. Nearly all of the aneurysms showed no increase in diameter over a >2-year mean follow-up, which supports the midterm adequacy of the CPG technique as a method to effectively revascularize branch vessels with few endoleaks or branch occlusions.

Acute kidney injury (AKI) after any type of intervention negatively impacts mortality, length of hospitalization, and perhaps long-term survival. In the case of endovascular aneurysm repair (EVAR), the incidence of AKI ranges from 1% to 23% for elective and emergency procedures and is lower compared to open repair. ⋯ Prevention strategies include hydration, ischemic preconditioning, regional anesthesia, and pharmacological agents. There is no level I evidence regarding the prevention of AKI in EVAR, so this review sought to examine the mechanisms and prevention strategies for this potentially fatal complication.

To describe the use of protective stents in the endovascular repair of acute complicated Stanford type B aortic dissections. ⋯ Adjunctive use of a protective stent when treating acute Stanford type B aortic dissections in which the diameters of the proximal and distal landing zones differ by >5 mm is feasible and safe and provides good short-term outcomes.
