Time-dependent and site-dependent morphological changes in rupture-prone arteries: ovariectomized rat intracranial aneurysm model.

The pathogenesis of intracranial aneurysm rupture remains unclear. Because it is difficult to study the time course of human aneurysms and most unruptured aneurysms are stable, animal models are used to investigate the characteristics of intracranial aneurysms. The authors have newly established a rat intracranial aneurysm rupture model that features site-specific ruptured and unruptured aneurysms. In the present study the authors examined the time course of changes in the vascular morphology to clarify the...

Embolization Of Very Small (≤3mm) Unruptured Intracranial Aneurysms - A Large Single Center Experience On Treatment Of Unruptured Versus Ruptured Cases.

In selected cases, embolization can be indicated for very small unruptured intracranial aneurysms. Previous studies reported high intraprocedural rupture rates. Recent improvements of endovascular devices and availability of small soft platinum coils may lead to improved safety and efficacy profiles.

Angiographic characteristics of lobulated intracranial aneurysms.

Previous studies indicated that lobulated aneurysms are more susceptible to rupture than single-sac aneurysms. We aimed to determine the angiographic characteristics related to the lobulated shape of unruptured (UIAs) and ruptured (RIAs) intracranial aneurysms.

Double stent assisted coiling of intracranial bifurcation aneurysms in Y and X configurations with the Neuroform ATLAS stent: immediate and mid term angiographic and clinical follow-up.

Self-expandable stents have broadened the spectrum of endovascular treatment of intracranial aneurysms. However, procedures involving double stenting in Y/X configurations carry a relatively high risk of procedural complications. The Neuroform ATLAS, the evolution of Neuroform EZ, is a nitinol self-expanding hybrid/open cell stent which can be delivered through a low profile 0.017 inch catheter. We present our experience in the treatment of intracranial aneurysms with this stent in Y and X configurations.

Cost Comparison of Surgical Clipping and Endovascular Coiling of Unruptured Intracranial Aneurysms - A Systematic Review.

Rupture of unruptured intracranial aneurysms (UIA) is the main cause for subarachnoid hemorrhage (SAH). UIA are widespread among the population. Advanced technology enables us to diagnose UIAs with increasing reliability and subsequently treat them. There are two main treatment options: surgical clipping and endovascular treatment of the aneurysm. This paper aims to analyze costs of neurosurgical clipping and the endovascular approach to treat UIA and to give an overview over the existing literature.

Management of Unruptured Intracranial Aneurysms in Older Adults: A Cost-effectiveness Analysis.

Background Unruptured intracranial aneurysms (UIAs) are relatively common and are being increasingly diagnosed, with a significant proportion in older patients (˃ 65 years old). Serial imaging is often performed to assess change in size or morphology of UIAs since growing aneurysms are known to be at high risk for rupture. However, the frequency and duration of surveillance imaging have not been established. Purpose To evaluate the cost-effectiveness of routine treatment (aneurysm coil placement) versus fo...

Vessel Wall Imaging Predicts the Presence of Atherosclerotic Lesions in Unruptured Intracranial Aneurysms.

and Purpose: Recent studies have suggested that MR vessel wall imaging (VWI) can visualize thicken intracranial aneurysm wall. To investigate correlations between VWI findings and intraoperative aneurysm wall features based on the hypothesis that VWI can visualize atherosclerotic changes in unruptured intracranial aneurysm (UIA) walls.

Coiling as a rescue strategy for flow diverter prolapse into a giant intracranial aneurysm.
