Natural history of dolichoectatic vertebrobasilar aneurysms: a multinational study.

Objective: Dolichoectatic vertebrobasilar aneurysms (DVBAs) are expansions of arterial tissue leading to aneurysmal formations without an obvious neck. Their natural history is poorly understood; usually patients are admitted with thromboembolic complications and/or neurological symptoms from the mass effect. There have not been international collective data, and correct timing for highly risky treatments has been under discussion.

Embolization of the Middle Meningeal Artery for Chronic Subdural Hematoma.

Background: Patients receiving standard treatment for chronic subdural hematoma have a high risk of treatment failure. The effect of adjunctive middle meningeal artery embolization on the risk of treatment failure in this population remains unknown.

Methods: We randomly assigned patients with symptomatic chronic subdural hematoma to undergo middle meningeal artery embolization as an adjunct to standard treatment (embolization group) or to receive standard treatment alone (control group).

SOFIA Aspiration System as first-line Technique (SOFAST): a prospective, multicenter study to assess the efficacy and safety of the 6 French SOFIA Flow Plus aspiration catheter for endovascular stroke thrombectomy.

Background: Mechanical thrombectomy (MT) is the standard of care for acute ischemic stroke (AIS) patients with large vessel occlusion (LVO). The SOFAST study collected clinical evidence on the safety and efficacy of the 6 French SOFIA Flow Plus aspiration catheter (SOFIA 6F) when used as first-line treatment.

Methods: This was a prospective, multicenter investigation to assess the safety and efficacy of SOFIA 6F used for first-line aspiration.

Evaluation of flow diverters for cerebral aneurysm therapy: recommendations for imaging analyses in clinical studies, endorsed by ESMINT, ESNR, OCIN, SILAN, SNIS, and WFITN.

Background: Multiple studies and meta-analyses have described the technical and clinical outcomes in large cohorts of aneurysm patients treated with flow diverters (FDs). Variations in evaluation methodology complicate making comparisons among studies, hinder understanding of the device behavior, and pose an obstacle in the assessment of further advances in FD therapy.

Methods: A multidisciplinary panel of neurointerventionalists, imaging experts, and neuroradiologists convened with the goal of establishing consensus recommendations for the standardization of image analyses in FD studies.

The pEGASUS-HPC stent system for intracranial arterial stenosis: a single-center case series.

Background: Intracranial arterial stenting is a technique for the treatment of symptomatic stenosis. In this single-center retrospective case series we evaluated a novel low profile laser-cut stent with an antithrombogenic hydrophilic polymer coating (pEGASUS-HPC, Phenox GmbH, Bochum, Germany) for the treatment of intracranial stenosis in the setting of acute ischemic stroke and elective cases.

Methods: All patients treated with pEGASUS-HPC for one or more intracranial arterial stenoses at our institution were retrospectively included.
