Results of endovascular aortic arch repair using the Relay Branch system.

Objectives: Our goal was to evaluate results of endovascular aortic arch repair using the Relay Branch system.

Methods: Forty-three patients with thoracic aortic pathology involving the aortic arch have been treated with the Relay Branch system (Terumo Aortic, Sunrise, FL, USA) in 10 centres. We assessed in-hospital mortality, neurological injury, treatment success according to current reporting standards and the need for secondary interventions.

Combining Volumetric and Wall Shear Stress Analysis from CT to Assess Risk of Abdominal Aortic Aneurysm Progression.

Background Despite known limitations, the decision to operate on abdominal aortic aneurysm (AAA) is primarily on the basis of measurement of maximal aneurysm diameter. Purpose To identify volumetric and computational fluid dynamics parameters to predict AAAs that are likely to progress in size. Materials and Methods This study, part of a multicenter prospective registry (NCT01599533), included 126 patients with AAA.

Single aortic branch device: the Mona LSA experience.

Endovascular treatment of aortic arch pathologies is challenging due to its complex anatomical architecture and the presence of vital collateral branches. This paper aims to provide an overview of the currently available and future endovascular options for these diseases, particularly regarding branched stent-grafts and the Mona LSA device. After discussing the indications for revascularization of supra-aortic trunks in endovascular aortic repair, we present the principles, benefits and drawbacks of the main modern methods to overcome an insufficient proximal landing zone, i.

Orthotopic branched endovascular aortic arch repair in patients who cannot undergo classical surgery.

Objectives: Our goal was to assess the results after orthotopic branched endovascular aortic arch repair using a new double-branch endoprosthesis in patients with thoracic aortic disease affecting the aortic arch who cannot undergo classical surgery.

Methods: Within a 4-year period, 15 patients with thoracic aortic disease affecting the aortic arch were treated with the Bolton Relay plus double-branch endoprosthesis (Bolton Medical, Sunrise, FL, USA). We assessed clinical outcome, occurrence of endoleaks and the need for secondary interventions.

Incidence, etiology, and management of type III endoleak after endovascular aortic repair.

Objective: The objective of this study was to retrospectively assess the incidence, etiology, and management of type III endoleaks in a large cohort of patients treated with endovascular aneurysm repair (EVAR) in two European university centers.

Methods: From 1995 until 2014, 965 EVAR procedures were performed with use of first- and second-generation (n = 79) or third-generation (n = 886) endografts. Radiologic follow-up was performed with computed tomography and abdominal plain film examinations in accordance with the European Collaborators on Stent/graft Techniques for aortic Aneurysm Repair (EUROSTAR) scheme.

French multicenter experience with the GORE TIGRIS Vascular Stent in superficial femoral and popliteal arteries.

Background: Preliminary results in small single-center studies after stenting with the GORE TIGRIS Vascular Stent (W. L. Gore & Associates, Flagstaff, Ariz) show promising short-term primary patency rates, but larger, multicenter studies are needed.

The neutral sphingomyelinase-2 is involved in angiogenic signaling triggered by oxidized LDL.

Capillaries of the external part of the normal arterial wall constitute the vasa vasorum network. In atherosclerotic lesions, neovascularization occurs in areas of intimal hyperplasia where it may promote plaque expansion, and intraplaque hemorrhage. Oxidized LDL that are present in atherosclerotic areas activate various angiogenic signaling pathways, including reactive oxygen species and the sphingosine kinase/sphingosine-1-phosphate pathway.
