Complex and unstable flow patterns are reported to be associated with the rupture status of cerebral aneurysms, while their evaluation depends on qualitative analysis of streamlines of bloodflow. Oscillatory velocity index (OVI) is a hemodynamic parameter to quantify flow patterns. The aim of this study is to elucidate the associations between OVI and the rupture status of cerebral aneurysms. ⋯ High OVI was associated with rupture status, and morphological and hemodynamic characteristics of ruptured aneurysms. These results indicate that OVI may serve as a valuable hemodynamic parameter for diagnosing rupture status and risks of aneurysms.

Factors that determine aneurysm occlusion after embolization with the Woven EndoBridge (WEB).
The Woven EndoBridge (WEB) device is a novel endovascular tool for the treatment of wide-necked intracranial aneurysms. ⋯ The WEB provides a high rate of adequate occlusion even in a subset of complex wide-necked intracranial aneurysms. Anatomic results tend to be less favourable in large and partially thrombosed aneurysms and after treatment with WEB and coil.

To compare the safety and efficiency of stent assisted coiling (SAC) with non-SAC for the management of ruptured intracranial aneurysms. ⋯ SAC has a lower recurrence rate than non-SAC. Nevertheless, further validation by well designed prospective studies is warranted for determining whether stents improve angiographic outcome without an increased complication rate or unfavorable clinical outcome.

Treatment strategies for recurrent and residual aneurysms after Woven Endobridge implantation.
Woven Endobridge (WEB) embolization is a safe and efficient technique for endovascular treatment of intracranial aneurysms. However, the management of aneurysm recurrence after WEB placement has not been well described to date. We present our multicenter experience of endovascular retreatment of aneurysm recurrence after WEB implantation. ⋯ This pilot study shows that endovascular retreatment of recurrent or residual aneurysms after WEB implantation can be done safely and can achieve adequate occlusion rates.

Woven EndoBridge (WEB) deployment remains challenging in aneurysms with a complex shape or orientation. ⋯ The balloon remodeling-assisted WEB technique seems to be a safe and effective solution for endovascular treatment of unruptured wide-neck bifurcation aneurysms with specific complex anatomy. However, further studies are needed to evaluate the rate of complications and long-term efficacy.
