Usefulness of Non-Contrast-Enhanced MR Angiography Using a Silent Scan for Follow-Up after Y-Configuration Stent-Assisted Coil Embolization for Basilar Tip Aneurysms.

Usefulness of Non-Contrast Enhanced Magnetic Resonance Angiography Using Silent Scan for Follow-Up after Y Stent- Assisted Coil Embolization for Basilar Tip Aneurysms

Assessing Blood Flow in an Intracranial Stent: A Feasibility Study of MR Angiography Using a Silent Scan after Stent-Assisted Coil Embolization for Anterior Circulation Aneurysms.

BACKGROUND AND PURPOSE Blood flow in an intracranial stent cannot be visualized with 3D time-of-flight MR angiography owing to magnetic susceptibility and radiofrequency shielding. As a novel follow-up tool after stent-assisted coil embolization, we applied MRA by using a Silent Scan algorithm that contains an ultrashort TE combined with an arterial spin-labeling technique (Silent MRA). The pur...

Treatment of intracranial broad-neck aneurysms with a new self-expanding stent and coil embolization.

BACKGROUND AND PURPOSE Endovascular treatment of broad-neck intracranial aneurysms with detachable coils requires special techniques. Placement of a stent over the aneurysm neck and secondary coil embolization prevents coil migration and allows attenuated packing of the coils. However, access for the stent-delivery system can be technically limited in tortuous anatomy. We present six cases of b...

Staged Y-shaped Stent Assisted Coil Embolization in a Wide-Neck Basilar Tip Aneurysm: Case Report

to treat with endovascular embolization. Balloon remodeling and stent-assisted coil embolization have been increasingly available therapeutic strategy in the treatment of these complex lesions (1-3). To our knowledge, there are a few papers that wide-necked basilar bifurcation aneurysms were treated with the Yconfigured dual stent assisted coil embolization (4-6). But all patients were unruptur...

Y-stent-assisted coil embolization of wide-neck intracranial aneurysms. A single center experience.

This report evaluated the short and midterm results of the safety and effectiveness of the treatment technique with hybrid and non-hybrid Y-configured, dual stent-assisted coil embolization of wide-neck intracranial aneurysms, and reviewed the literature concerning this technique. Nine patients, eight with unruptured and one with ruptured aneurysms were included in the study. Of aneurysms embol...
