A Deep Learning Approach to Automate High-Resolution Blood Vessel Reconstruction on Computerized Tomography Images With or Without the Use of Contrast Agent [PDF]

arXiv, 2020
Existing methods to reconstruct vascular structures from a computed tomography (CT) angiogram rely on injection of intravenous contrast to enhance the radio-density within the vessel lumen. However, pathological changes can be present in the blood lumen, vessel wall or a combination of both that prevent accurate reconstruction. In the example of aortic

Successful hybrid management of a ruptured abdominal aortic aneurysm induced by type II and IIIB endoleaks after endovascular aortic repair

Journal of Vascular Surgery Cases and Innovative Techniques, 2019
Ruptured abdominal aortic aneurysm after endovascular abdominal aortic repair is a relatively rare condition. The management of this type of a rupture is challenging and controversial.

Assessment of Aortic Aneurysm Rupture Risk [PDF]

arXiv, 2011
The rupture of an abdominal aortic aneurysm (AAA) is associated with a high mortality. When an AAA ruptures, 50% of the patients die before reaching the hospital. Of the patients that are able to reach the operating room, only 50% have it successfully repaired (Fillinger et al, 2003).

3D Path Planning from a Single 2D Fluoroscopic Image for Robot Assisted Fenestrated Endovascular Aortic Repair [PDF]

, 2018
The current standard of intra-operative navigation during Fenestrated Endovascular Aortic Repair (FEVAR) calls for need of 3D alignments between inserted devices and aortic branches. The navigation commonly via 2D fluoroscopic images, lacks anatomical information, resulting in longer operation hours and radiation exposure.

Angiogenesis in abdominal aortic aneurysms

European Journal of Vascular and Endovascular Surgery, 1996
To determine the degree of neovascularisation in the wall of abdominal aortic aneurysms in comparison to atherosclerotic control aortas, and to correlate the angiogenic response with the extent of the cellular inflammatory infiltrate.Histopathological study.Aortic samples were obtained from patients with abdominal aortic aneurysms and from ...

Open surgical repair of abdominal aortic aneurysm: Proximal aortic control by endoaortic balloon - A novel approach

Annals of Cardiac Anaesthesia, 2012
Patients with infrarenal abdominal aortic aneurysm with unfavorable anatomy for endovascular aneurysm repair have to undergo open surgical repair. Open surgery has its own morbidity in terms of proximal clamping and declamping, bleeding and prolonged ...
