Multicenter Study
Endovascular treatment of patients with types A and B thoracic aortic dissection using Relay thoracic stent-grafts: results from the RESTORE Patient Registry.
To evaluate the safety and performance of Relay stent-grafts in patients with acute or chronic aortic dissections. ⋯ The combination of Relay's features, such as stent conformability, radial force, atraumatic design, and controlled deployment and fixation, may contribute to the safety of the Relay stent-grafts for the treatment of thoracic aortic dissections, including acute and chronic type B dissections.

Case Reports
Inferior vena cava stent-graft placement to treat endoleak associated with an aortocaval fistula.
To report a case in which a persistent high-flow type II endoleak after endovascular aneurysm repair (EVAR) of a leaking abdominal aortic aneurysm (AAA) complicated by an aortocaval fistula was repaired with a stent-graft in the inferior vena cava (IVC). ⋯ Aortocaval fistulae should be excluded in the case of persistent type II endoleaks after EVAR for ruptured AAAs. IVC endografting is a minimally invasive alternative to treat such a complication, with promising midterm results in this patient.

To investigate the secondary procedures in patients with previous endovascular aortic repair by fenestrated or branched stent-grafts for aneurysms involving the renal and visceral vessels. ⋯ The incidence of early and late complications requiring a secondary procedure after treatment with fenestrated or branched devices was not negligible. Endoleak type III represented the most common cause for reintervention during follow-up. Secondary procedures performed for visceral vessel compromise had high rates of treatment failure. Accurate preoperative planning, the advent of new materials/techniques, and strict follow-up could be the key factors to improving the results of fenestrated or branched stent-graft interventions and to reduce the rate of secondary procedures.
