Objective: Prehension of the position of the microcatheter tip under fluoroscopy during cerebral aneurysm embolization is critical to prevent intraoperative rupture of the aneurysm, even if the first marker at the tip is obscured by coils in the aneurysm. This study presents our initial experience with a sub-marker catheter, which includes an additional marker positioned 5 mm from the tip, designed to facilitate accurate positioning of the microcatheter tip.
Methods: We analyzed cases of cerebral aneurysms treated with sub-marker catheters at our hospital from July 2022 to September 2023. Single catheter embolization served as the primary treatment option, with balloon-assisted or stent-assisted techniques utilized only when necessary.
Results: During the study period, 18 patients with cerebral aneurysms were treated using sub-marker catheters. The median age of these patients was 65 years, comprising 8 men and 10 women. The aneurysms had a median maximum diameter of 6.2 mm, ranging from 5.0 to 16.8 mm. Among the 18 treated patients, 14 had unruptured aneurysms and 4 had ruptured aneurysms. Treatment methods included single catheter embolization in 10 patients, double catheter embolization in 3, stent-assisted embolization in 3, balloon-assisted embolization in 1, and flow diverter placement combined with coil embolization in 1. The sub-marker was consistently visible under fluoroscopy, aiding the precise positioning of the microcatheter tip without interference from the coils. No complications occurred, and successful embolization was achieved in all cases.
Conclusion: The sub-marker catheter appears valuable for safely performing aneurysm embolization.

Objective: This study was to explore the factors associated with prolonged hospital length of stay (LOS) in patients with intracranial aneurysms (IAs) undergoing endovascular interventional embolization and construct prediction model machine learning algorithms.
Methods: Employing a retrospective cohort study design, this study collected patients with ruptured IA who received endovascular treatment at Jingzhou First People's Hospital during the inclusion period from September 2022 to December 2023. The entire dataset was randomly split into training and testing dataset with a 7:3 ratio.

Background: Past studies have reported that vertebrobasilar dolichoectasia (VBD) patients may develop similar arteriopathies other than the vertebrobasilar system. However, the details of these VBD-related arteriopathies are still unclear.
Methods: We retrospectively enrolled patients diagnosed with VBD at two stroke centers in Japan between January 2012 and December 2023.

Aneurysmal Subarachnoid Hemorrhage (aSAH), resulting from ruptured aneurysms, is a major contributor to stroke-related mortality and morbidity. Despite advances in healthcare, aSAH remains severe and often leads to complications such as cerebral vasospasm (CV), cerebral infarction, and delayed ischemic neurological deficits (DIND). Clazosentan, an endothelin receptor antagonist, has demonstrated potential in alleviating vasospasm and its associated outcomes, although evidence of its efficacy remains unclear.

Background And Purpose: This study evaluates the early clinical performance of the new Artisse Intrasaccular Device (Artisse ISD), a self-expandable intrasaccular flow diverter, for treating wide-necked aneurysms (WNAs). We report initial safety and efficacy outcomes in the first cohort of patients treated with this novel device.
Methods: Prospective clinical and radiological data were collected for all patients treated with the Artisse ISD at three Austrian neurovascular centers from July 2023 to August 2024.
