  • aorta
  • Optical coherence tomography images of human thoracic aorta from aneurysms reveal elastin disorders and smooth muscle cell alterations when visualizing the media layer of the aortic wall. (spiedigitallibrary.org)
  • Human thoracic aorta from aneurysms reveal elastin disorders and smooth muscle cell alterations when visualizing the media layer of the aortic wall, which is only some tens of microns in depth from surface. (spie.org)
  • Surgery
  • Cardiovascular surgeons face certain challenges in open surgery: to prevent postoperative pseudoaneurysm formation if the graft is sutured close to a degraded aortic wall and to be able to evaluate the quality of the aortic arch to extend the graft placement if necessary. (spiedigitallibrary.org)
  • However, there is a potential benefit of the muscle as it can be used as a flap in a reconstructive surgery of the head and neck and the anterior chest wall. (wikipedia.org)
  • In children, teenagers, and young adults who have pectus carinatum and are motivated to avoid surgery, the use of a customized chest-wall brace that applies direct pressure on the protruding area of the chest produces excellent outcomes. (wikipedia.org)
  • vessel wall
  • 1 This pathological growth generally induces an underlying weakness in the vessel wall, and the main concern is to minimize the risk of rupture of the vessel. (spiedigitallibrary.org)
  • organs
  • Occasionally, a localised injury to the osseous part of the chest wall can occur (rib fracture, sternal fracture and sternoclavicular dislocation) or, rarely, direct impact forces may be transmitted through the chest wall to the deeper organs, causing serious injury to the heart, lung or large mediastinal vessels.

  • indicators for wall degradation
  • These disorders can be employed as indicators for wall degradation and, therefore, become a hallmark for diagnosis of risk of aneurysm under intraoperative conditions. (spiedigitallibrary.org)
  • The resulting images require a suitable processing to enhance interesting disorder features and to use them as indicators for wall degradation, converting OCT into a hallmark for diagnosis of risk of aneurysm under intraoperative conditions. (spie.org)
  • aortic wall
  • Two approaches are followed to evaluate this risk: the analysis of the reflectivity decay along the penetration depth and the textural analysis of a two-dimensional spatial distribution of the aortic wall backscattering. (spiedigitallibrary.org)
  • Results show that the alterations in the media layer of the aortic wall are better highlighted when the textural approach is considered and also agree with a semiquantitative histopathological grading that assesses the degree of wall degradation. (spiedigitallibrary.org)
  • These techniques are believed to be useful in these applications as aortic wall disorders directly affect the refractive index of the tissue, having an effect on the gradient of the tissue reflectivity that conform the OCT image. (spie.org)
  • Injuries
  • Injuries from a direct impact are usually less dangerous and affect mainly the soft tissues of the chest wall (haematomas, rubbings). (springer.com)
