A case of successful replacement of two coexistent chronic post-traumatic aneurysms of the thoracic aorta is presented. Presumably, these aneurysms at the aortic isthmus and the descending thoracic aorta resulted from two different deceleration traumas.

OBJECTIVES This study observed midterm results of vascular ring connectors in surgery for aortic dissection. METHODS Vascular ring connectors were used as stents in vascular grafts to achieve quick, sutureless anastomoses. Tapes were used to secure ringed vascular grafts from outside the aorta. RESULTS From November 2007 to February 2011, 113 consecutive patients with aortic dissection, exc...

OBJECTIVE Perivascular adipose tissue depots around the aorta are regionally distinct and have specific functional properties. Thoracic aorta perivascular adipose tissue (tPVAT) expresses higher levels of thermogenic genes and lower levels of inflammatory genes than abdominal aorta perivascular adipose tissue (aPVAT). It is not known whether this distinction is due to the in-vivo functional env...

Endogenous superoxide anion (O(-)(2)) interferes with the bioactivity of nitric oxide (NO) in endothelium-dependent arterial relaxation (EDR). Using the lucigenin chemiluminescence assay, we measured O(-)(2) in the thoracic and abdominal aortas and the carotid artery of rabbits to determine whether ambient O(-)(2) varies among the three arteries and differentially diminishes the effect of NO. B...

The aortic root has unique embryological development and is a highly sophisticated complex structure. In studies that report on the biomechanical characteristics of thoracic aorta, distinction between ascending aorta regions non-existent. This study aimed to determine maximal pressures at which dissection or tissue failure occur in both aneurysmal analyse any differences. may help guide preoper...

OBJECTIVE We developed a novel method using anatomic markers along the thoracic aorta to accurately quantify longitudinal and circumferential cyclic strain in nondiseased thoracic aortas during the cardiac cycle and to compute age-related changes of the human thoracic aorta. METHODS Changes in thoracic aorta cyclic strains were quantified using cardiac-gated computed tomography image data of ...

ABSTRACT Dysphagia aortica is an uncommon condition defined by the difficulty in swallowing caused by extrinsic compression of the esophagus due to an ectatic, tortuous, or aneurysmatic atherosclerotic thoracic aorta. We report the case of a 93 year old woman with dysphagia secondary to extrinsic compression by a giant sacciform aneurysm of the descending thoracic aorta. As a consequence of sma...

Esophageal cancer invading the muscularis mucosa sometimes involves regional lymph node metastases. However, lymph node metastases are rare in the dorsal area of the thoracic aorta. We describe a patient with an intramucosal esophageal cancer invading the muscularis mucosa, accompanied by lymph node metastases in the dorsal area of the thoracic aorta. These lesions were successfully resected by...

Frequency The prevalence of aortic aneurysms is higher than 3-4% in persons over 65 and over the last 30 years the overall prevalence has increased significantly. The estimated incidence of thoracic aortic aneurysms is 6 cases per 100.000 person/years. Classification Thoracic aneurysms (TAA) are subdivided into 3 groups depending on location: n aneurysm of ascending aorta+/-valvular lesion name...
