Microguidewire Looping to Traverse Stented Parent Arteries of Intracranial Aneurysms

OBJECTIVE Stents are widely used in coil embolization of intracranial aneurysms, but on occasion, a microcatheter must traverse a stented segment of artery (so-called trans-cell technique) to select an aneurysm, or double stenting may necessary. In such situations, microguidewire passage and microcatheter delivery through a tortuous stented parent artery may pose a technical challenge. Describe...

Recommendations for accurate numerical blood flow simulations of stented intracranial aneurysms.

The number of scientific publications dealing with stented intracranial aneurysms is rapidly increasing. Powerful computational facilities are now available; an accurate computational modeling of hemodynamics in patient-specific configurations is, however, still being sought. Furthermore, there is still no general agreement on the quantities that should be computed and on the most adequate anal...

Filling abnormalities of intracranial arteries (so-called vasospasm). Angiographical analyses of 63 cases with intracranial aneurysms.

Wall viscosity of the stented arteries.

Wall Viscosity of the Stented Arteries To the Editor: In the November 2003 issue of Stroke, Vernhet and colleagues reported a clinical analysis of wall mechanics in stented extracranial carotid arteries, and they concluded that stenting of these arteries induces a compliance mismatch between the native and the stented artery. Additionally, the authors observed a significant decrease in the dist...
