option for treatment of thoracic aortic diseases. Cross-sectional radiologic imaging plays a
crucial role for evaluating a patient’s candidacy for planning of the intervention and for
assessment of postprocedural results and complications of TEVAR. Recent advances in
imaging technologies, in part inspired by advances in stent-graft technology, have drastically
changed the character and role of pre- and po |

Materials and methods: An elastic tube phantom mimicking the descending aorta was developed with the possibility to insert an aortic nitinol stent graft. Different flow patterns (constant, sinusoidal and pulsatile aortic flow) were applied by a gear pump. A two-dimensiona |

A 74-year-old man with a history of infrarenal abdominal aortic aneurysm repair presented with bilateral common iliac and left femoral aneurysms as well as a thoracic aortic aneurysm. He underwent an open repair of the iliac and femoral aneurysms, followed by thoracic endovascular aneurysm repair in a staged manner without complications. Ten months later, he presented with hypotension, and permanent parap |

Proper sizing and shaping require the measurement of the orthogonal diameter of the target region from medical images. The present study aimed to acquire an accurate three-dimensional(3D) reconstruction of the aorta to determine the shape fo the cross-sectional area where the stent graft would be implanted. A |

The function of these blood vessels has successfully been studied in the framework
of biology, physics, and imaging. |
