Thoracic endovascular aortic repair (TEVAR) in the current era has been chosen as a dominant and minimally invasive treatment for complicated aorta dissection. This study aimed to assess safety and feasibility of TEVAR in acute and chronic type B aortic dissection.Between January 2011 and December 2013, 85 patients with complicated type B aortic dissection undergoing TEVAR were divided into acu...

Acute type A aortic dissection is a potentially lethal condition which requires immediate diagnostic and therapeutic intervention. Open surgical repair remains the standard of care as survival rates continue to improve in the modern surgical era. Unfortunately, up to twenty percent of patients are denied surgical therapy because they are deemed medically unfit to undergo open repair. The applic...

Acute type B dissection is a catastrophic condition. Up to 20% of these patients develop severe complications such as rupture or branch vessel malperfusion. These challenging patients are usually triaged to surgical or endovascular management. The surgical approach has been the gold standard for treatment of complicated type B dissection. However, the management has been challenging even in cen...

The prognosis of chronic aortic dissection lies in the existence of thrombus blockage and in the degree of blood pressure control of the false lumen, among other prognostic factors reported. The incidence of aortic dissection increases with age. Despite advances in diagnostic techniques, the mortality in the acute phase in Japan is substantially high. In the chronic phase, computed tomography (...

BACKGROUND In our study, we aimed to demonstrate the utility of MR imaging in the emergency diagnosis of acute aortic dissection. METHODS Herein, 15 patients who were clinically suspected as having aortic dissection were assessed with both magnetic resonance imaging and 3D contrast enhanced MR angiography by means of a 1.5 tesla magnet. RESULTS Eleven patients were diagnosed as having aorti...

Acute aortic dissection is a life-threatening condition, and may be treated with aggressive hypotensive drug therapy, but emergency surgery is often necessary. We evaluated the effectiveness of stent-grafts for the treatment of acute aortic dissection. Aortic dissection was surgically created in the descending thoracic aorta in 20 adult mongrel dogs. A stent-graft was inserted in the entry posi...
