OBJECTIVES The purpose of this study was to investigate the role of shear stress (SS) in plaque regression. BACKGROUND A condition favorable to the development of atherosclerotic lesions is low oscillating SS. In the descending thoracic aorta, the relationship between plaque distribution and SS has never been characterized. The regression of plaque as the result of lipid-lowering therapy is a...

BACKGROUND Imaging of the aorta has received less attention than imaging of the coronary beds, despite the possible link between aortic and coronary artery disease (CAD). Electron beam computed tomography (EBCT) with 100 ms scanning speed can eliminate pulsation-related motion artifacts. The goals of this study were to evaluate EBCT-detected subclinical atherosclerosis over the whole aorta as i...

BACKGROUND Acute descending thoracic aortic dissection is a life-threatening emergency. It is not often considered as the initial diagnosis in patients presenting with epigastric pain and could easily be missed in a busy casualty department. AIM This case report is aimed to highlight the feasibility of the technique and the need for long-term surveillance following endovascular repair of acut...

BACKGROUND Blunt thoracic aortic injury (BTAI) is associated with a high mortality rate and the paradigm of treating patients with BTAI currently favours thoracic endovascular aneurysm repair (TEVAR) if possible. In BTAI, lethal malperfusion caused by a pseudoaneurysm has rarely been reported. We present the first report of a successful case in which a pseudoaneurysm causing the infrequent occu...

We report a case of concurrent saccular aneurysms caused by a penetrating atherosclerotic ulcer of the thoracic and abdominal aorta that were successfully treated by staged endovascular repair. Even though surgical open repair or endovascular repair is the treatment option, use of endovascular repair is now accepted as an alternative treatment to surgery in selected patients. To prevent contras...
