چکیده
Background and objectives: Endovascular prosthesis placement is a predominant surgical procedure to reduce the risk of aneurysm rupture in abdominal aortic patients. The formation an endoleak major complication stent-graft placement. Therefore, aim this study was determine influence stent-graft’s spatial configuration on leakage under realistic flow conditions. Materials Methods: We analyzed data collected from 10 male patients 55 ± 3 years old after CTA who had undergone endovascular treatment. Computational Fluid Dynamics technique applied for reconstruction blood hemodynamic. Two cases were each time, with without endoleak, reconstructed one patient endoleak. Endoleak-free geometries prepared by virtual closure opening. Results: It observed that high value velocity around may provoke its slowly rupture, which increase sack case type II endoleaks. Moreover, appearance reduces average entire some contribute coagulation. Furthermore, no clot can form at site due wall shear stress near prevents thrombosis.

Computational Fluid Dynamics: Science and Tool
The year 2003 marked the 100th anniversary of both the birth of John von Neumann and the first manned flight with a power plane. In the current paper, from a Dutch perspective, attention is paid to the great importance of both events for computational fluid dynamics in general and computational aerodynamics in particular. 2000 Mathematics Subject Classification: 01-08; 65-03

Gliders are new marine vehicles which have research and military uses and they move by sequent diving and climbing. Suitable design of its main body and wings are important for the most advance velocity. hydrodynamic design variables are main body form, wings (cross section, dimensions, shape, longitudinal and vertical position) and hydrostatic parameters (static trim angle, amount of added for...
متن کاملManagement of Endoleaks following Endovascular Aneurysm Repair.
Endovascular aneurysm repair (EVAR) has emerged as a viable alternative to open repair for abdominal aortic aneurysms. Endoleaks are a complication unique to EVAR and can occur in up to 25% of patients. In this article, the management of endoleaks following EVAR will be discussed.
