Current Status of Endovascular Therapy of Cerebral Berry Aneurysms
Autopsy reports have shown that cerebral aneurysms are present in roughly 5% of population [1-3]. Subarachnoid hemorrhage (SAH) is the most serious presentation of ruptured cerebral aneurysms. Estimated annual incidence of non-traumatic SAH ranges from 2 to 23 cases per 100,000, which translates to 6,500 to 74,000 annual cases of SAH in the United States. Approximately 80% of non-traumatic SAH ...
متن کاملHemodynamics of three cerebral aneurysms with daughter aneurysms
The mechanisms of development, growth and rupture of cerebral aneurysms are still incompletely understood. However, blood flow is believed to have a major impact. Some aneurysms develop smaller aneurysms, so-‐called daughter aneurysms -‐ see figure. In this study the influence of these daughter aneurysms was investigated. The blood flow with and without these daughter aneurysms was simulated ...
متن کاملیافته های آنژیوگرافی در آنوریسم داخل جمجمه ای، بیمارستان امام، 79-1374
Background: This investigation was conducted in order to study angiographic findings in patients with cerebral aneurysm. Materials and Methods: The study conducted on 136 cases of ruptured cerebral aneurysms between 1995-2000 confirmed by means of 4-vessel cerebral angiography to get an insight to racial, geographic and environmental factors predisposing to the occurrence of subarachnoid hemorr...
متن کاملUsing COMSOL Multiphysics for Biomechanical Analysis of Stent Technology in Cerebral Aneurysms
This work presents new fluid-structure interaction (FSI) models in both 2D and 3D of the effect of using vascular stents as treatment of cerebral berry aneurysms. The stent is positioned inside the cerebral artery covering the neck of the aneurysm. The stent is expected to alter the blood flow into the aneurysm such that the blood coagulates due to low blood velocity, and rupture of the aneurys...
متن کاملThe hemodynamic study for growth factor evaluation of rupture cerebral aneurysm followed up for five years
Computer-based simulations are essential for clarifying the hemodynamics of brain aneurysms. Since cerebrovascular disease is often fatal, it is strongly desirable to predict its progression. While previous studies have clarified the initiation mechanism of aneurysms, their growth mechanism remains unclear. Consequently, it is difficult to develop a diagnostic system for predicting aneurysm rup...
