Randomized Study Comparing First-Line Dual Versus Single-Stent Retriever Technique: TWIN2WIN.

Background: The double-stent retriever (SR) technique has been described as an effective rescue technique when single-SR fails to induce recanalization. We aimed to assess the safety and efficacy of first-line double-SR in patients with stroke undergoing thrombectomy.

Methods: This was a multicenter, randomized, controlled, blinded adjudicated primary outcome study.

Guillain-Barré syndrome associated with leptomeningeal enhancement following SARS-CoV-2 infection.

Introduction: Patients with coronavirus disease 2019 (COVID-19) typically present with respiratory symptoms, but little is known about the disease's potential neurological complications.We report a case of Guillain-Barré syndrome (GBS) following a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, in association with leptomeningeal enhancement.

Case Presentation: A 56-year-old woman presented with recent unsteadiness and paraesthesia in both hands.

Repeated Mechanical Thrombectomy in the Same Intracranial Artery Segment.

We report a patient with an important scenario that may arise in the management of an acute ischemic stroke: the need for a repeated mechanical thrombectomy in the same intracranial artery segment. The patient had a history of atrial fibrillation and a mechanical mitral valve replacement. In her first stroke, she had an occlusion of the proximal segment of the right middle cerebral artery; 58 days later, she presented with an occlusion in the same segment of that cerebral artery.

[Head and neck paragangliomas: imaging diagnosis and embolization].

Objectives: To review imaging features of paragangliomas. To determine the usefulness of pre-operative embolization.

Material And Method: From January 1994 to December 2004, 30 patients at our institution were found to have 33 paragangliomas of the head and neck.
