Subarachnoid hemorrhage often leads to poor outcomes owing to vasospasm, even after successful aneurysm treatment. Clazosentan, an endothelin receptor inhibitor, has been proven to be an effective treatment for vasospasms in a Japanese randomized controlled trial. However, its efficacy in older patients (≥ 75 years old) and those with World Federation of Neurosurgical Societies (WFNS) grade V has not been demonstrated.
View Article and Find Full Text PDFA dural arteriovenous fistula (dAVF) involving the superior sagittal sinus (SSS) is relatively rare, and its clinical course is usually aggressive. Its concomitance with a tumor has rarely been reported. Here, we present a case of SSS dAVF due to meningioma invasion, which was treated with sinus reconstruction and endovascular embolization.

We aimed to investigate and propose a new index marker, the vertebral blush (VB) sign, for assessing the treatment efficacy of SCAVSs.
Methods: This retrospective cohort study enrolled patients diagnosed with SCAVSs between June 2012 and May 2021.
Background: Guiding catheter (GC) advancement into the target carotid artery is a crucial step in neuroendovascular therapy. In difficult anatomies, alternative methods have been reported to overcome difficult carotid access for swift GC advancement. However, studies focusing on the positional relationship between the GC and inner catheter (IC) at the aortic arch are lacking.

- Cerebral venous thrombosis (CVT) is a rare stroke-related condition, linked to systemic and hereditary causes, with a case report highlighting a 47-year-old woman who presented with severe movement issues and altered consciousness due to CVT and systemic thromboembolism.
- Medical imaging revealed significant brain swelling and complications like deep vein thrombosis and pulmonary embolism, while blood tests indicated that hyperhomocysteinemia and iron-deficiency anemia were caused by autoimmune gastritis.
- The patient received anticoagulant treatment along with iron and vitamin B12 supplementation, ultimately leading to her discharge without any neurological deficits, showcasing a positive treatment outcome.
Background: We aimed to quantify the tortuosity of the middle cerebral artery (MCA) and assess its effects on radiological and clinical outcomes in patients with acute MCA occlusions who received mechanical thrombectomy (MT).
Methods: This retrospective study enrolled 53 patients with acute ischemic stroke due to MCA M1 or M2 segment occlusion who underwent MT using stent retrievers (SRs). Tortuosity index (TI) was defined to quantify the tortuosity of the MCA M1 segment using the following formula: (actual distance / straight distance) × 100.
