Stromal cell-derived factor 1α (SDF-1α), a vital inflammation cytokine, is also related to aneurysm pathogenesis. However, the characteristics of SDF-1α expression and its role in aneurysm remodeling remain largely unknown.

Objective: To present 2 cases of Parkes Weber syndrome (PWS) with spinal arteriovenous malformation (AVM) and discuss the radiologic features and clinical treatment with literature review.
Methods: Clinical data on 2 patients with PWS with spinal AVM was acquired in a prospective follow-up investigation. Clinical manifestations, radiographic features, procedural results, and follow-up outcome were collected and reviewed together with a literature review.
Objectives: To explore the association of baseline characteristics and the outcome of patients with acute basilar artery occlusion (BAO) after stent retriever-based thrombectomy (SRT).
Methods: Clinical and imaging information of consecutive SRT-treated patients with BAO from a comprehensive stroke center and up-to-date literature were reviewed respectively. The impact of baseline variables toward favorable outcome was evaluated using subgroup analysis and odds ratio (OR) extracted from published data together with single-center records using pooled analysis.
Objective: This report aimed to review the angiographic characteristics and evaluate the safety and feasibility of endovascular treatment of A1 aneurysms.
Methods: Nineteen ruptured and 13 unruptured A1 aneurysms treated endovascularly were evaluated in this study. The angiographic and clinical records were retrospectively reviewed.

Endovascular embolization has evolved to become the primary therapeutic option for dural arteriovenous fistulas (DAVFs). While guaranteeing complete occlusion of the fistula orifice, the goal of DAVF embolization is also to ensure the patency of normal cerebral venous drainage. This paper describes a case of successful embolization of a complex DAVF in the superior sagittal sinus with a multistaged approach using a combination of transvenous and transarterial tactics.
