Mechanical evaluation of decellularized porcine thoracic aorta.
BACKGROUND Decellularized tissues are expected to have major cellular immunogenic components removed and in the meantime maintain similar mechanical strength and extracellular matrix (ECM) structure. However, the decellularization processes likely cause alterations of the ECM structure and thus influence the mechanical properties. In the present study, the effects of different decellularization...
متن کاملFunctional chiral asymmetry in descending thoracic aorta.
To determine whether rotational blood flow or chiral asymmetry exists in the human descending thoracic aorta, we established the ability of color Doppler ultrasound to detect rotational flow in a tornado tube model of a vortex descending fluid column. In a model of the human aortic arch with a pulse duplicator, color Doppler was then used to demonstrate that rotational flow occurs first in the ...
متن کامل[Endovascular treatment of descending thoracic aorta aneurysm].
BACKGROUND The natural history of aneurysms ends in rupture and death. In 1990 the first endovascular exclusion of an aneurysm, using an endoluminal graft implanted through the femoral arteries was performed. More recently, the same procedure has been used for aneurysms of the thoracic aorta. AIM To report our experience with endovascular treatment of thoracic aorta aneurysms. MATERIAL AND ...
متن کاملDeterminants of mechanical properties in the developing ovine thoracic aorta.
We previously reported changes in mechanical properties and collagen cross-linking of the ovine thoracic aorta during perinatal development and postnatal maturation, and we now report changes in biochemical composition (elastin, collagen, and DNA contents per mg wet wt) over the same developmental intervals. A comparison of results from the present and previous studies has yielded novel and imp...
متن کاملMycotic aneurysm of descending thoracic aorta
Mycotic aneurysm has become rare since the introduction of penicillin. However, clinicians should be aware and consider the possibility as delayed treatment can lead to poor outcomes. We report the case of a 23-year-old Malay lady with congenital scoliosis presenting with back pain and fever. Computer tomography scan showed a large pseudo-aneurysm of descending thoracic aorta and a smaller pseu...
