Stretchable wireless sensor could monitor healing of cerebral aneurysms（图）
Stretchable wireless sensor monitor healing cerebral aneurysms
2019/10/18
A wireless sensor small enough to be implanted in the blood vessels of the human brain could help clinicians evaluate the healing of aneurysms -- bulges that can cause death or serious injury if they ...
Over the last 50 years, significant progress has been made in the surgical repair of thoracoabdominal aortic aneurysms (TAAA). Improvements in perioperative care and surgical techniques have resulted...
One method of treating ruptured anterior communicating aneurysms is presented. This permits early clipping through a bifrontal flap. Key branches of the circle of Willis are temporarily occluded by sp...
Multiple Aneurysms of the Left External Jugular Vein
Multiple venous aneurysm jugular vein children
2009/6/23
True venous aneurysms are rarely encountered local dilatations, in contrast to arterial aneurysms (1). Congenitally elastic layers and muscle cells are insufficient or even do not exist in vein walls ...
Growth rate and rupture rate of unruptured intracranial aneurysms: a population approach
Growth rate rupture rate unruptured intracranial aneurysms
2010/2/25
This mathematical model can be used to predict aneurysm growth rate, and the results are consistent with previous clinical studies. Predictions from both hypothetical and clinical cases agree very wel...
A comparison of modelling techniques for computing wall stress in abdominal aortic aneurysms
modelling techniques wall stress abdominal aortic aneurysms
2010/2/25
The results here show that using more realistic parameters affect resulting wall stress. The use of simplified computational modelling methods can lead to inaccurate stress distributions. Care should ...
Modeling of the aorta artery aneurysms and renal artery stenosis using cardiovascular electronic system
the aorta artery aneurysms renal artery stenosis cardiovascular electronic system
2010/2/25
The results showed the decreasing of pressure along the aorta and renal arteries lengths, due to the aneurysms and stenosis, at the peak systole. The mathematical method demonstrated that compliances ...
3D geometric reconstruction of thoracic aortic aneurysms
3D geometric reconstruction thoracic aortic aneurysms
2010/2/26
This paper presents a new approach to the reconstruction of an aneurysm model based on the use of several sets of MR images. This enables more accurate representation of not only the lumen but also th...
SURGICAL OUTCOMES IN PATIENTS WITH ANTERIOR COMMUNICATING ARTERY ANEURYSMS
Aneurysm Anterior communicating artery Subarachnoid hemorrhage Outcome
2010/4/19
AcomA aneurysms are complicated and high incidence lesions. The successful treatment depends on understanding the anatomical location of aneurysm. The early surgery and selecting the superior method o...
Fluid structure interaction of patient specific abdominal aortic aneurysms: a comparison with solid stress models
Fluid structure interaction patient specific abdominal aortic aneurysms solid stress models
2010/2/26
Abdominal aortic aneurysm (AAA) is a dilatation of the aortic wall, which can rupture, if left untreated. Previous work has shown that, maximum diameter is not a reliable determinant of AAA rupture. H...
Analysis and computer program for rupture-risk prediction of abdominal aortic aneurysms
computer program rupture-risk prediction abdominal aortic aneurysms
2010/2/26
As part of computational AAA-risk assessment and medical management, a patient-specific severity parameter 0 < SP(t) < 1.0 has been developed. The time-dependent, normalized SP(t) depends on eight bio...
Fluid-structure interaction in abdominal aortic aneurysms: effects of asymmetry and wall thickness
Fluid-structure interaction abdominal aortic aneurysms
2010/2/26
Both wall thickness and geometry asymmetry affect the stress exhibited by a virtual AAA. Our results suggest that an asymmetric AAA with regional variations in wall thickness would be exposed to highe...
A Case of Behcet’s Disease with Arterial Occlusion and Multiple Aneurysms
aneurysm angiograph Behcet’s Disease
2010/2/5
Vascular involvement in Behçet’s disease is divided into venous and arterial thrombosis and arterial aneurismal formation. Multiple arterial aneurysms rarely occur in Behçet’s disease; h...
Numerical analysis of giant brain aneurysms
haemodynamic pattern biophysical properties of cerebral aneurysms
2010/3/11
This paper focuses on the analysis of the haemodynamic pattern and biophysical properties of cerebral aneurysms, diagnosed and delineated in living human individuals. An aneurysm is a bulging out of p...
