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.
-
To present a prospective, single-center trial of the Cardiva Catalyst II, a vascular closure device that provides temporary hemostasis after the procedure and is removed under manual compression, leaving no material behind. ⋯ Cardiva Catalyst is safe and effective device in achieving local hemostasis after percutaneous diagnostic procedures and interventions performed under bivalirudin anticoagulation. The use of this device with an appropriate protocol facilitates same-day discharge.

Case Reports
Near-infrared spectroscopy for monitoring spinal cord ischemia during hybrid thoracoabdominal aortic aneurysm repair.
To describe a simple, noninvasive technique to detect changes in oxygen saturation at the level of the spinal cord and to suggest its suitability for individualized blood pressure management during and after thoracoabdominal aneurysm repair. ⋯ These data show that NIRS monitors post-endograft changes in S(s)O(2) that were strongly related to arterial blood pressure. Regional NIRS monitoring at the vertebral level may function as a valuable noninvasive guide to the management of blood pressure during thoracoabdominal aneurysm repair, both intra- and postoperatively.
