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.

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.

To examine the feasibility, efficacy, and midterm results of endovascular stent-graft management of acute type B aortic dissection complicated by renal, visceral, or lower limb malperfusion. ⋯ Endovascular coverage of the proximal entry tear in acute type B dissections complicated by end-organ malperfusion resulted in correction of malperfusion in the majority of patients. It is a reasonable first line of treatment, but its superiority must be assessed in comparison with other techniques, such as fenestration.

To describe a new endovascular approach to preserve internal iliac artery (IIA) flow in patients with abdominal aortic aneurysm (AAA) involving the common iliac artery(ies) (CIA) or in cases of isolated CIA/IIA aneurysm. ⋯ This technique was developed to overcome current anatomical and device constraints, expanding the limits of endovascular aneurysm repair (EVAR) in a safe, easy to perform, and cost-effective manner. The sandwich technique appears a promising tool in the EVAR armamentarium, but more experience with the method is warranted.
