A 2D cellular automaton biofilm detachment algorithm
(2012)A cellular-automaton based two-dimensional biofilm detachment module is developed. The module is an improvement of previously presented methodologies for modeling biofilm detachment under the influence of hydrodynamic ... -
Abdominal Aortic Aneurysm Endovascular Repair: Profiling Postimplantation Morphometry and Hemodynamics with Image-Based Computational Fluid Dynamics
(2018)Endovascular aneurysm repair (EVAR) has disseminated rapidly as an alternative to open surgical repair for the treatment of abdominal aortic aneurysms (AAAs), because of its reduced invasiveness, low mortality, and morbidity ... -
Analytical side-to-side related anastomotic strategies and artery patching
(2015)Suture line stress concentration and intimal hyperplasia are related to the long-term complications of end-toside and side-to-side anastomosis. Several factors, such as hemodynamic effects, biological activities and the ... -
Black-blood CMR
(2015)Cardiac magnetic resonance is often used to provide detailed information on structures such as the myocardium, pericardium, pulmonary veins, and emanating great vessels. While blood travels throughout the heart and blood ... -
Comparison of physiological and post-endovascular aneurysm repair infrarenal blood flow
(2017)Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms results in redirection of blood through the deployed endograft (EG). Even though EVAR is clinically effective, the absolute flow restoration is not warranted. ... -
Effect of macroscale formation of intraluminal thrombus on blood flow in abdominal aortic aneurysms
(2014)A mathematical approach of blood flow within an abdominal aortic aneurysm (AAA) with intraluminal thrombus (ILT) is presented. The macroscale formation of ILT is modeled as a growing porous medium with variable porosity ... -
Effect of macroscale formation of intraluminal thrombus on blood flow in abdominal aortic aneurysms
(2016)A mathematical approach of blood flow within an abdominal aortic aneurysm (AAA) with intraluminal thrombus (ILT) is presented. The macroscale formation of ILT is modeled as a growing porous medium with variable porosity ... -
Hemodynamic profile of two aortic endografts accounting for their postimplantation position
(2017)Endovascular aneurysm repair (EVAR) is a clinically effective technique for treating anatomically eligible abdominal aortic aneurysms (AAAs), involving the deployment of an endograft (EG) that is designed to prevent blood ... -
In-stent graft helical flow intensity reduces the risk of migration after endovascular aortic repair
(2019)During the last years endovascular aneurysm repair (EVAR) became the elective treatment for abdominal aortic aneurysms (AAAs) thanks to lower mortality and morbidity rates than open surgery. In face of these advantages, ... -
The ovation abdominal stent graft for the treatment of abdominal aortic aneurysms: Current evidence and future perspectives
(2016)The Ovation Abdominal Stent Graft System is a trimodular endoprosthesis recently introduced for the endovascular repair of abdominal aortic aneurysm (AAA). It uncouples the stages of stent-graft fixation and sealing with ... -
Simulation of magnetic nanoparticles crossing through a simplified blood-brain barrier model for Glioblastoma multiforme treatment
(2021)Background and Objectives: Glioblastoma multiforme is considered as one of the most aggressive types of cancer, while various treatment techniques have been proposed. Magnetic nanoparticles (MNPs) loaded with drug and ... -
Suture Line Response of End-to-Side Anastomosis: A Stress Concentration Methodology
(2015)End-to-side vascular anastomosis has a considerable complexity regarding the suturing of the juncture line between the artery and the graft. The present study proposes a stress–concentration methodology for the prediction ... -
Τhe AFX unibody bifurcated unibody aortic endograft for the treatment of abdominal aortic aneurysms: current evidence and future perspectives
(2020)Introduction: AFX is a bifurcated unibody aortic endograft for the treatment of Abdominal Aortic aneurysms. It consists of an inner metallic endoskeleton with multiple metallic struts covered by a polytetrafluoroethylene ...
