Detection and Visualization of Endoleaks in CT Data for Monitoring of Thoracic and Abdominal Aortic Aneurysm Stents [PDF]
, 2016 In this paper we present an efficient algorithm for the segmentation of the inner and outer boundary of thoratic and abdominal aortic aneurysms (TAA & AAA) in computed tomography angiography (CTA) acquisitions. The aneurysm segmentation includes two steps: first, the inner boundary is segmented based on a grey level model with two thresholds; then, an ...

Thresholds for Abdominal Aortic Aneurysm Repair in England and the United States.
New England Journal of Medicine, 2016 BACKGROUND Thresholds for repair of abdominal aortic aneurysms vary considerably among countries. METHODS We examined differences between England and the United States in the frequency of aneurysm repair, the mean aneurysm diameter at the time of the ...

Journal of Immunology, 2016 Abdominal aortic aneurysm is a dynamic vascular disease characterized by inflammatory cell invasion and extracellular matrix degradation. Damage to elastin in the extracellular matrix results in release of elastin-derived peptides (EDPs), which are ...

Genes Associated with Thoracic Aortic Aneurysm and Dissection: 2019 Update and Clinical Implications
Aorta, 2016 Thoracic aortic aneurysm is a typically silent disease characterized by a lethal natural history. Since the discovery of the familial nature of thoracic aortic aneurysm and dissection (TAAD) almost 2 decades ago, our understanding of the genetics of this

Der Internist, 2009 Abdominal aortic aneurysms (AAA) confer a substantial healthcare burden in the Western world. Surgical or endovascular therapy is indicated in patients with a maximum diameter exceeding 5.5 cm. Patients with smaller AAA must undergo a specific ultrasound surveillance program aimed at avoiding exposure to an increased risk of rupture once their AAA ...

Long‐term follow‐up of fenestrated endovascular repair for juxtarenal aortic aneurysm
British Journal of Surgery, 2017 Fenestrated endovascular aneurysm repair (FEVAR) is increasingly being used for juxtarenal aortic aneurysms. The aim of this study was to review long‐term results and assess the importance of changing stent‐graft design on outcomes.

Determination, Calculation and Representation of the Upper and Lower Sealing Zones During Virtual Stenting of Aneurysms [PDF]
Int J CARS, Vol. 5, Suppl. 1, pp. 13-14, Springer Press, June 2010, 2013 In this contribution, a novel method for stent simulation in preoperative computed tomography angiography (CTA) acquisitions of patients is presented where the sealing zones are automatically calculated and visualized. The method is eligible for non-bifurcated and bifurcated stents (Y-stents).

Modelling of aortic aneurysm and aortic dissection through 3D printing
Journal of Medical Radiation Sciences, 2017 The aim of this study was to assess if the complex anatomy of aortic aneurysm and aortic dissection can be accurately reproduced from a contrast‐enhanced computed tomography (CT) scan into a three‐dimensional (3D) printed model.

Abdominal Aortic Aneurysm Segmentation with a Small Number of Training Subjects [PDF]
arXiv, 2018 Pre-operative Abdominal Aortic Aneurysm (AAA) 3D shape is critical for customized stent-graft design in Fenestrated Endovascular Aortic Repair (FEVAR). Traditional segmentation approaches implement expert-designed feature extractors while recent deep neural networks extract features automatically with multiple non-linear modules.
