1. Endothelial Progenitor Cells and NADPH Oxidase Enzyme Activity in the Development of an Aortic Aneurysm
Abstract Introduction: Endothelial progenitor cells (EPCs) and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase enzyme activity may affect the vessel wall and have a role in development of aortic aneurysms. EPCs originate from hematopoietic stem cells and can be enumerated from peripheral blood samples by flow cytometry. In this study, we aimed t

2. Which is the Optimal Frozen Elephant Trunk? A Systematic Review and Meta-Analysis of Outcomes in 2161 Patients Undergoing Thoracic Aortic Aneurysm Surgery Using E-vita OPEN PLUS Hybrid Stent Graft versus Thoraflex™ Hybrid Prosthesis
Abstract Objective: To systematically review the rate of morbidity and mortality associated with the use of E-vita hybrid stent graft and ThoraflexTM in patients undergoing complex aortic surgery. Methods: A comprehensive search was undertaken among the four major databases to identify published data about E-vita or Thoraflex™ in patients undergoing repa

4. Aneurisma de aorta torácica em paciente com esclerose tuberosa
Resumo A esclerose tuberosa é uma doença genética de transmissão autossômica dominante. Caracteriza-se, na sua apresentação clássica, por epilepsia, deficiência mental e adenomas sebáceos. Aneurismas de aorta podem acometer desde crianças com poucos meses de vida até adultos jovens portadores de esclerose tuberosa. Apresentamos o caso de uma paci

5. Relationships Between Phenotype and Function of Blood CD4+ T-Cells and Ascending Thoracic Aortic Aneurysm: an Experimental Study
Abstract Introduction: Non-familial ascending thoracic aorta dilation and aneurysms (TAAs) are silent diseases in elderly patients. Histopathology revealed that functionally polarized infiltrating CD4+ T-cells play a key role in aortic wall weakening. Objective: To evaluate the possible associations between phenotype and cytokine production of circulating

6. Hybrid Approach of Aortic Diseases: Zone 1 Delivery and Volumetric Analysis on the Descending Aorta
Abstract Introduction: Conventional techniques of surgical correction of arch and descending aortic diseases remains as high-risk procedures. Endovascular treatments of abdominal and descending thoracic aorta have lower surgical risk. Evolution of both techniques - open debranching of the arch and endovascular approach of the descending aorta - may extend a

7. α-Smooth Muscle Actin and ACTA2 Gene Expressions in Vasculopathies
ABSTRACT α-smooth muscle actin, encoded by ACTA2 gene, is an isoform of the vascular smooth muscle actins, typically expressed in the vascular smooth muscle cells contributing to vascular motility and contraction. ACTA2 gene mutations cause a diversity of diffuse vasculopathies such as thoracic aortic aneurysms and dissections as well as occlusive vascular

8. Neuroprotective effect of atorvastatin in spinal cord ischemia-reperfusion injury
OBJECTIVES: Prevention of the development of paraplegia during the repair of the damage caused by descending thoracic and thoracoabdominal aneurysms remains an important issue. Therefore, we investigated the protective effect of atorvastatin on ischemia-induced spinal cord injury in a rabbit model. METHOD: Thirty-two rabbits were divided into the following

9. Correção dos Aneurismas da Aorta Torácica e Toracoabdominal: Técnica de Canulação Central.
Introduction: The surgical treatment of the aneurysm of descending thoracic and thoracoabdominal aorta are related with risk of spinal cord ischemic, as well as, coagulation and renal function disorders. Among the spinal cord protection methods, there are liquor drainage, temporary bypass, intercostal arteries implant, deep hypothermia, selective cooling of

10. Use of transesophageal echocardiography during implantation of aortic endoprosthesis (stent). Initial experience
OBJECTIVE: To report the role played by transesophageal echocardiography during implantation of self-expanding aortic endoprostheses (stent) at a hemodynamics laboratory. METHODS: Thirteen patients underwent stent implantation in the descending thoracic aorta with the aid of transesophageal echocardiography during the entire procedure. Indications for stenti

11. Rupture of the Thoracic Aorta: Emergency Treatment and Management of Chronic Aneurysms
Between 1957 and 1983, 58 patients were treated in our institution for traumatic rupture of the thoracic aorta. Seven patients had acute ruptures and 51 had traumatic aneurysms.

12. Proximal clamping levels in abdominal aortic aneurysm surgery.
In the surgical treatment of abdominal aortic aneurysm, the single proximal cross-clamp can be placed at 3 alternative aortic levels: infrarenal, hiatal, and thoracic. We performed this retrospective study to evaluate the advantages and disadvantages of the 3 main aortic clamping locations. Eighty patients presented at our institution with abdominal aortic a
