Mechanical thrombectomy via chronic occluded proximal artery for the endovascular treatment of acute ischemic stroke patients with large vessel occlusion.

Background: Mechanical thrombectomy (MT) can significantly improve the prognosis of acute ischemic stroke patients with large vessel occlusion. However, for patients with chronic occluded proximal artery, therapeutical strategies are limited because the endovascular route for MT is not readily accessible.

Methods: Here, we introduce a safe and effective MT procedure via a chronic occluded proximal artery.

Long-term efficacy and safety of curative embolization of brain arteriovenous malformations using the dual microcatheter technique: A single-institution case series and literature review.

Objective: Brain arteriovenous malformations (bAVMs) are among the most common causes of cerebral hemorrhage in adolescents. For multiple-feeder bAVMs, complete exclusion of the nidus by endovascular embolization is challenging. This case series and literature review examined the long-term efficacy and safety of bAVM embolization using the dual microcatheter technique (DMCT).

Long-term follow-up of transarterial balloon-assisted Onyx embolization for endovascular treatment of dural arteriovenous fistulas: A single-institution case series and literature review.

Objective: Dural arteriovenous fistulas (DAVFs)-specifically, symptomatic DAVFs with cortical venous reflux-are aggressive lesions with a poor prognosis. Intra-arterial endovascular closure is considered the optional treatment for DAVFs and is currently performed at several international centers. However, long-term outcomes remain unknown.
