Intracranial Aneurysms: Wall Motion Analysis for Prediction of Rupture.
Intracranial aneurysms are a common pathologic condition with a potential severe complication: rupture. Effective treatment options exist, neurosurgical clipping and endovascular techniques, but guidelines for treatment are unclear and focus mainly on patient age, aneurysm size, and localization. New criteria to define the risk of rupture are needed to refine these guidelines. One potential can...
متن کاملWall enhancement ratio and partial wall enhancement on MRI associated with the rupture of intracranial aneurysms.
OBJECTIVES To evaluate the risk factors for rupture of intracranial aneurysms (IAs) using high resolution MRI (HRMRI). METHODS 91 consecutive patients with 106 IAs were reviewed from February 2016 to April 2017. Patients and IAs were divided into ruptured and unruptured groups. In addition to the clinical characteristics of the patients, the features of IAs (eg, shape) were evaluated by CT an...
متن کاملThe Computational Fluid Dynamics Rupture Challenge 2013—Phase I: prediction of rupture status in intracranial aneurysms.
BACKGROUND AND PURPOSE Rupture risk assessment for intracranial aneurysms remains challenging, and risk factors, including wall shear stress, are discussed controversially. The primary purpose of the presented challenge was to determine how consistently aneurysm rupture status and rupture site could be identified on the basis of computational fluid dynamics. MATERIALS AND METHODS Two geometri...
متن کاملFactors Influencing Intraoperative Rupture of Intracranial Aneurysms.
AIM The study deals with intraoperative rupture of intracranial aneurysms (IOR) during microsurgery, analyzing factors that may be connected with IOR. MATERIAL AND METHODS During the three-year period (2006-2008), 934 patients were operated for aneurysms at the Institute of Neurosurgery, CCS, Belgrade. In total, 536 patients were observed. RESULTS IOR occurred in 14.7%. Male gender, seizure...
متن کاملIntracranial aneurysms: individualising the risk of rupture.
The decision of what to do with asymptomatic unruptured intracranial aneurysms is a fairly new problem. Although these aneurysms have been known to exist for centuries through autopsies and for several decades through catheter angiography, their true prevalence did not begin to emerge until the use of non-invasive angiograms became widespread in the recent past. Now we know that nearly 3% of th...
