  • The natural history of saccular intracranial aneurysms consists of three phases: initiation, growth, and either stabilization or rupture, and the application of scientific principles to biological processes has made it easier to understand the behavior of aneurysm formation and rupture.

  • The purpose of this study is to compare the clinical outcome of surgical clipping and endovascular coiling for ruptured intracranial aneurysms not included in the original ISAT Study. (centerwatch.com)
  • Further compounding the problem are the concerns that aneurysm coiling may not be as durable in the long-term as surgical clipping, leading many neurosurgeons to continue to clip most ruptured aneurysms in spite of ISAT results. (centerwatch.com)
  • The wider spectrum of patients and aneurysms now considered for EVT may not all experience the same degree of benefit as seen in the original ISAT trial (4). (centerwatch.com)
  • Less common causes are mycotic aneurysms, arteriovenous malformations, and bleeding disorders. (msdmanuals.com)
  • BackgroundIntracranial fusiform aneurysms are less common than saccular aneurysms, but are associated with higher mortality and morbidity. (journaltocs.ac.uk)
  • The common causes of intracranial aneurysm include hemodynamically induced or degenerative vascular injury, atherosclerosis (typically leading to fusiform aneurysms), underlying vasculopathy (eg, fibromuscular dysplasia), and high-flow states, as in arteriovenous malformation (AVM) and fistula.
