PURPOSE: To describe an innovative endovascular technique that successfully reconstructs a renal artery completely perfused by the false lumen after thoracic endovascular aortic repair (TEVAR). CASE REPORT: A 65-year-old patient diagnosed with acute Stanford type B aortic dissection underwent successful TEVAR 4 years ago. Regular follow-up found that the thoracic aorta was well repaired, but the false lumen in the abdominal aorta had enlarged year by year. The left renal artery was supplied entirely by the false lumen, which caused kidney hypoperfusion...

Current assessment and management of ascending thoracic aortic aneurysm (ATAA) rely heavily on the diameter of the ATAA and blood pressure rather than biomechanical and hemodynamic parameters such as arterial wall deformation or wall shear stress. The objective of the current study was to develop an accurate computational method for modeling the mechanical responses of the ATAA to provide additional information in patient evaluations. Fully coupled fluid structure interaction simulations were conducted using data from cases with ATAA with measured geometrical parameters in order to evaluate and analyze the change in biomechanical responses under normotensive and hypertensive conditions...

PURPOSE OF REVIEW: The appropriate treatment of bicuspid aortic valve (BAV)-associated aortopathy is still controversial. We aimed to summarize recent evidence from the literature that focused on the prediction of aortopathy progression and adverse aortic events. RECENT FINDINGS: Following the detailed description of valvulo-aortic phenotypes in BAV disease in the previous imaging studies, the most current research focused on the definition of hemodynamic markers that may affect the progression of BAV-associated aortopathy and search for blood-born biomarkers to improve the prediction of adverse aortic events...

Herein, we report the case of a 60-year-old man, a smoker with a history of arterial hypertension and diabetes mellitus. After computed tomography (CT) for an episode of hemoptysis, the patient underwent elective thoracic endovascular aortic repair (TEVAR) because of a degenerative aneurysm of the descending thoracic aorta. The area of perianeurysmal pulmonary atelectasis reported on the CT scan was not considered. Three months later, he developed an aortopulmonary fistula without endoleaks. Although TEVAR is a relatively safe procedure, no detail should be overlooked in the preoperative evaluation in order to avoid life-threatening complications...

Angiogenesis is an important process in the pathogenesis of aortic aneurysm. The aim of the present study was to investigate the angiogenic balance and the expression of vascular endothelial growth factor (VEGF) in thoracic aortic aneurysm (TAA). A previous study demonstrated that curcumin exerts a marked effect on aortic aneurysm development. Therefore, the present study determined whether curcumin is able to modulate angiogenesis and inflammatory signaling in TAA by collecting human TAA samples and establishing a rat TAA model using periaortic application of CaCl2...

Cellular and molecular mechanisms of thoracic aortic aneurysm are not clear and therapeutic approaches are mostly absent. Thoracic aortic aneurysm is associated with defective differentiation of smooth muscle cells (SMC) of aortic wall. Bicuspid aortic valve (BAV) comparing to tricuspid aortic valve (TAV) significantly predisposes to a risk of thoracic aortic aneurysms. It has been suggested recently that BAV-associated aortopathies represent a separate pathology comparing to TAV-associated dilations. The only proven candidate gene that has been associated with BAV remains NOTCH1...

A 77-year-old man, who had been under medical treatment for myasthenia gravis without thymoma, was diagnosed with aortic arch aneurysm. He underwent total aortic arch replacement and total resection of the thymus through median sternotomy. His symptoms relating to myasthenia gravis dramatically disappeared after the surgery. The serum anti-acetyl chorine receptor antibody decreased from 2.7 to 0.7 nmol/l (N<0.2) with the reduction of oral predonisolone from 12.5 to 5 mg/day at 4 years after the surgery. The concomitant operations significantly improved his quality of life...

An aortic aneurysm is a lethal arterial disease that mainly occurs in the thoracic and abdominal regions of the aorta. Thoracic aortic aneurysms are prevalent in the root/ascending parts of the aorta and can lead to aortic rupture resulting in the sudden death of patients. Understanding the biomechanical and histopathological changes associated with ascending thoracic aortic aneurysms (ATAAs), this study investigates the mechanical properties of the aorta during strip-biaxial tensile cycles. The loss factor-defined as the ratio of dissipated energy to the energy absorbed during a tensile cycle-the incremental modulus, and their anisotropy indexes were compared with the media fiber compositions for aneurysmal (n = 26) and control (n = 4) human ascending aortas...

The tertiary stage of syphilis is nowadays extremely rare, showing predilection for the cardiovascular and nervous systems. A 57-year-old Caucasian man sought medical assistance due to back pain that evolved to paraplegia of the lower limbs. A thoracic CT scan demonstrated an important aneurysmatic lesion of the descending thoracic aorta causing erosion of the vertebral bodies and VDRL and FTA-abs positivity. Although rare, syphilitic aortitis, the hallmark of cardiovascular syphilis, should be considered in the differential diagnosis in patients with thoracic aneurysm when in the absence of classic risk factors for atherosclerosis, especially in cases that progress with erosion of vertebral bodies...

OBJECTIVE: It is controversial whether microorganisms play a role in the pathogenesis of large and medium vessel vasculitides (eg, giant cell arteritis [GCA], Takayasu arteritis [TAK] and focal idiopathic aortitis [FIA]). Recent studies have reported the presence of Varicella Zoster Virus (VZV) within formalin-fixed, paraffin-embedded temporal arteries and aortas of about three-quarters or more of patients with these conditions, and in a minority of controls. In a prospective study, we sought to confirm these findings using DNA extracted from vessels that were harvested under surgically aseptic conditions and snap frozen...
