Article Abstract
Aim: To compare the outcomes and complications of stent-assisted coil (SAC) embolization for the treatment of cerebral aneurysms according to stent type.
Material And Methods: Since January 2006, a total of 1293 patients have been added to our institutional aneurysm database. We excluded cases with subarachnoid hemorrhage, those not classified as Raymond Roy Class 1, and those in which flow diverters were used. Cases involving the use of overlapping stents, Y-stenting, or multiple stents were also excluded. We recorded demographic information, aneurysm characteristics, and procedural details for all patients. Patients who did not undergo diffusionweighted magnetic resonance imaging (MRI) within 1 day postoperatively or follow-up angiography within 6 months postoperatively were excluded.
Results: In total, 188 patients were included in the analysis (129 females; mean age, 58 years) who were treated for aneurysms of different sizes. Regrowth occurred in 21 patients, with the rate varying according to the stent type. In particular, the lower profile stent group had a lower regrowth rate compared to the nitinol laser stent group. The rate of postoperative infarction on diffusionweighted MRI within 1 day postoperatively varied among stent types.
Conclusion: None of the stent types demonstrated clear superiority for SAC embolization, indicating that stent selection should be based on surgeon preference. Despite the low regrowth rate, careful stent selection is essential, particularly for patients at high risk of ischemic stroke or regrowth. These findings provide valuable insights for optimizing the treatment of cerebral aneurysms using SAC embolization.

Modelling cardiovascular disease is at the forefront of efforts to use computational tools to assist in the analysis and forecasting of an individual's state of health. To build trust in such tools, it is crucial to understand how different approaches perform when applied to a nominally identical scenario, both singularly and across a population. To examine such differences, we have studied the flow in aneurysms located on the internal carotid artery and middle cerebral artery using the commercial solver Ansys CFX and the open-source code HemeLB.

Wide-necked anterior communicating artery (ACoA) aneurysms pose challenges for endovascular coiling due to the risk of coil protrusion. This case report describes a new endovascular technique for managing ruptured wide-necked ACoA aneurysms, addressing the risk of coil protrusion during embolization. This method employs a combined microcatheter and guidewire-assisted embolization method, enabling coil deployment without needing adjunctive devices such as stents or balloons.

Fungal cerebral aneurysms, particularly those resulting from direct invasion by fungal sinusitis, are rare and often fatal when involving the cavernous segment of the internal carotid artery (ICA). We present a case of a ruptured fungal ICA aneurysm caused by sinusitis, successfully treated with parent artery occlusion (PAO). In this case, an 80-year-old woman presented with right ptosis, facial pain, and cranial nerve III, IV, and VI palsies.

Background And Purpose: Although high-resolution cone-beam computed tomography (HR-CBCT) is used for immediate evaluation of stent apposition, studies using this technique to evaluate flow diverter (FD) endothelialization during follow-up are limited. The study aims to investigate the potential of HR-CBCT in assessing FD endothelialization and identify factors influencing poor endothelialization.
Materials And Methods: The clinical and imaging data of patients with unruptured intracranial aneurysms (UIAs) treated by FDs from March 2019 to October 2023 were retrospectively analyzed.
