OBJECTIVES The purpose of this study was to determine the relevance of S100A12 expression to human thoracic aortic aneurysms and type A thoracic aortic aneurysm dissection and to study mechanisms of S100A12-mediated dysfunction of aortic smooth muscle cells. BACKGROUND Transgenic expression of proinflammatory S100A12 protein in murine aortic smooth muscle causes thoracic aneurysm in genetical...
Thoracic aortic aneurysm is often an asymptomatic but potentially lethal disease if its most catastrophic complication - aortic dissection - occurs. Thoracic aortic dissection is associated with a high mortality rate despite ongoing improvement in its management. We report a fatal outcome of thoracic aortic aneurysm in a male patient with bicuspid aortic valve. The patient was qualified for ele...
C omputed tomography angiography (CTA) of the thoracic aorta has benefited greatly from the advent of multidetector computerized tomography (MDCT). Three-dimensional reconstruction of large datasets allows easy evaluation of pathological changes of the aorta. This improvement coincides with changes in treating thoracic aortic aneurysms (TAAs) because accurate preoperative assessment is critical...
The treatment of descending thoracic aortic aneurysms using endovascular stents is one of the more recent advances in treatment and is receiving increasing attention as it is a less invasive alternative to open surgical repair. Although the technology is still primitive, significant improvements have lately been made in the design and deployment of the endovascular stent-grafts. Aortic stent-gr...
Previous data suggest women are at increased risk of death from aortic dissection. Therefore, we analyzed data from the GenTAC registry, the NIH-sponsored program that collects information about individuals with genetically triggered thoracic aortic aneurysms and cardiovascular conditions. We performed cross-sectional analyses in adults with Marfan syndrome (MFS), familial thoracic aortic aneur...
Thoracic endovascular aortic repair has become a widespread alternative treatment option for thoracic aortic aneurysm. The debranching of arch vessels may be required to provide an acceptable landing zone for an endovascular stent graft. We report a case where the bypass graft used in the thoracic endovascular aortic repair procedure compressed the left internal jugular vein, causing acute thro...
OBJECTIVE Thoracic endovascular aortic repair for chronic type B aortic dissection with associated descending thoracic aneurysm remains controversial. Concerns include potential ischemic complications due to branch vessel origin from the chronic false lumen and continued retrograde false lumen/aneurysm sac pressurization via fenestrations distal to implanted endografts. The present study examin...
Introduction: Double aortic arch (DAA) is a congenital anomaly of the aortic arch. It is the most common type of complete vascular ring. When it occurs, the connected segment of the aortic arch and its branches encircle the trachea and esophagus, leading to symptoms related to these two structures. Case Report: We present a case of a newborn baby who developed biphasic stridor immediately after...
Acute aortic syndromes including aortic rupture remain lifethreatening, and represent a unique area in cardiovascular surgery. Thoracic endovascular aortic repair (TEVAR) has become widely accepted as a major option in the treatment of thoracic aortic diseases, particularly for emergency patients such as those with a ruptured dissection [1,2]. We report a case with type B aortic dissection that...
The rupture of a thoracic aortic aneurysm is a life-threatening emergency. Conventional open surgical repair carries a high mortality and morbidity. We report an elderly patient who suffered from rupture of a proximal descending thoracic aortic aneurysm close to the aortic arch. A hybrid operation consisting of a right-to-left carotid bypass followed by endovascular repair of the descending tho...
