Biaxial rupture properties of ascending thoracic aortic aneurysms.
UNLABELLED Although hundreds of samples obtained from ascending thoracic aortic aneurysms (ATAA) of patients undergoing elective surgical repair have already been characterized biomechanically, their rupture properties were always derived from uniaxial tensile tests. Due to their bulge shape, ATAAs are stretched biaxially in vivo. In order to understand the biaxial rupture of ATAAs, our group d...
متن کاملThoracic Aortic Aneurysms
The true incidence and mortality rate of TAAs is not known. A population-based study reported an incidence of 5.9 new aneurysms per 100,000 person-years in a Midwestern community over a 30-year period with median ages of 65 years for men and 77 years for women. 51% of aneurysms were in the ascending aorta, 11% in the arch and 38% in the descending thoracic aorta. Prevalence may be at least 3-4 ...
متن کاملNovel measurement of relative aortic size predicts rupture of thoracic aortic aneurysms.
BACKGROUND Optimal operative decision making in thoracic aortic aneurysms requires accurate information on the risk of complications during expectant management. Cumulative and yearly risks of rupture, dissection, and death before operative repair increase with increasing aortic size, but previous work has not addressed the impact of relative aortic size on complication rates. METHODS Our ins...
متن کاملThoracic and abdominal aortic aneurysms.
Aneurysms of the aorta are at times evaluated and treated by physicians from a number of specialties. Indeed, whereas cardiac surgeons operate on the ascending aorta and arch and vascular surgeons manage abdominal aortic aneurysms, at present the responsibility often falls to cardiologists to oversee the medical care of patients with aortic disease of all types. However, although formally train...
متن کاملRupture of aortic aneurysms into the gut.
Rupture of an aortic aneurysm into the gut is uncommon. The duodenum is most often involved, stomach and jejunum being next in order of frequency. Involvement of the cesophagus is now decidedly rare probably due to the declining incidence of cardiovascular syphilis. We report three cases of aortic aneurysm; two in the abdomen ruptured into the second part of the duodenum and one in the thorax i...
