A systematic review and meta-analysis of Woven EndoBridge single layer for treatment of intracranial aneurysms.
CONCLUSION: Woven EndoBridge single-layer is a promising new low-profile device especially for wide-neck bifurcation aneurysms, both ruptured and unruptured. No antiplatelet medication is needed which is a great advantage, especially in ruptured aneurysms. Efficacy and safety compare favorably with (stent-assisted) coiling. However, no direct comparison with other treatments is available as yet. PMID: 32028824 [PubMed - as supplied by publisher] (Source: Interventional Neuroradiology)

Pathogenesis of non-hereditary brain arteriovenous malformation and therapeutic implications.
Authors: Ota T, Komiyama M Abstract Brain arteriovenous malformations have a high risk of intracranial hemorrhage, which is a substantial cause of morbidity and mortality in patients with brain arteriovenous malformations. Although a variety of genetic factors leading to hereditary brain arteriovenous malformations have been extensively investigated, their pathogenesis is still not well elucidated, especially in sporadic brain arteriovenous malformations. The authors have reviewed the updated data of not only the genetic aspects of sporadic brain arteriovenous malformations, but also the architecture of microvascul...

Emergent carotid artery stenting in patients with acute ischemic stroke due to cervical internal carotid artery steno-occlusive lesion: Comparison of tandem intracranial occlusion and isolated cervical internal carotid artery occlusion.
CONCLUSIONS: Endovascular treatment in patients with acute ischemic stroke due to cervical internal carotid artery steno-occlusive lesion is a technically feasible and clinically effective intervention regardless of intracranial occlusion. Therefore, we recommend endovascular treatment regardless of the presence of concomitant intracranial artery occlusion for patients with acute ischemic stroke caused by cervical internal carotid artery steno-occlusive lesion.
