Systemic anticoagulation is the standard treatment for cerebral venous sinus thrombosis (CVST). Several endovascular techniques have been described as salvage therapy for anticoagulation refractory CVST cases. We aim to evaluate the safety and feasibility of endovascular aspiration thrombectomy using the new generation, large bore suction catheters alone or in combination with stentriever devices for the treatment of CVST. ⋯ Endovascular aspiration treatment using large bore suction catheters for CVST is a safe and feasible approach for the treatment of anticoagulation refractory CVST. Heterogeneity of the clinical and radiological presentation requires further investigation to optimize patient selection before evaluating the efficacy of this technique in larger prospective studies.

Less can be more: Targeted embolization of aneurysms associated with arteriovenous malformations unsuitable for surgical resection.
To mitigate risks of hemorrhage, high-risk features of brain arteriovenous malformations (BAVMs) can be targeted to reduce the risk of rupture. Previous investigation has examined embolization of a pedicle supplying a high-risk feature; this study examines embolization targeted specifically at aneurysms associated with BAVMs. ⋯ In inoperable BAVMs, targeted embolization of associated aneurysms can be performed safely and effectively. This should be considered in high-risk lesions prior to radiosurgery or in cases when no other treatment options are available. Such intervention warrants further investigation.

Long-term occlusion results with SILK flow diversion in 28 aneurysms: Do recanalizations occur during follow-up?
The purpose of this article is to report on the long-term success rates of Silk flow-diverter (FD) treatment in a multicenter prospective study for the treatment of complex aneurysms. ⋯ Anatomic presentation and location are key for successful FD treatment. The rate of successful occlusion increases during follow-up. Postinterventional monitoring for at least six months is paramount, as anatomic outcome is not reliably predictable and recanalizations may occur in initially completely occluded aneurysms.
