Purpose: This study aims to investigate the indications and therapeutic efficacy of flow-diverting stents (FDSs) in the management of extracranial carotid artery aneurysms (ECAAs) and dissections.

Methods: A retrospective analysis was conducted on 18 patients treated for ECAAs with an FDS between 2010 and 2024. Patient demographics, aneurysm characteristics, procedural details, and clinical and radiologic follow-up outcomes were extracted from medical records.

This study introduces a machine learning (ML) approach to diagnosing carotid artery diseases, including stenosis, aneurysm, and dissection, by leveraging craniocervical computed tomography angiography (CTA) data. A meticulously curated, balanced dataset of 122 patient cases was used, ensuring reproducibility and data quality, and this is publicly accessible at (insert dataset location). The proposed method integrates a super learner model which combines adaptive boosting, gradient boosting, and random forests algorithms, achieving an accuracy of 90%.

Purpose: To evaluate the safety, efficacy, and long-term outcomes of transarterial chemoembolization (TACE) with bleomycin-Lipiodol for giant liver hemangiomas.

Materials And Methods: Single-center retrospective study from 1998 to January 2020, including patients with giant liver hemangiomas treated with bleomycin-Lipiodol TACE and followed up >36 months. The exclusion criteria were defined as patients who had been treated but had no available follow-up above 3 years and patients who had previously been treated with any other treatment method.

Background And Purpose: This study aims to elucidate the early changes in blood biochemistry thrombosis parameters following stent-assisted endovascular treatment of intracranial aneurysms.

Methods: Consecutive patients with unruptured aneurysms undergoing stent implantation during endovascular treatment were included in this prospective study with approval from the local ethics committee. Blood samples were collected immediately before and 24 h after the procedure for biochemical analysis, including basic thrombosis indicators, bleeding tests, and a complete blood count.

Aim: To evaluate the safety and efficacy of flow diverter stents (FDSs) for treating remnant or recurrent intracranial aneurysms that were treated surgically.

Material And Methods: The patients who were treated with FDSs due to remnant or recurrent intracranial aneurysms after microsurgery were included in the study. The patients' demographics, treatment histories, aneurysm features, complications associated with flow diversion, and neurological and angiographic follow-up findings were evaluated.

Background/aim: The aim of this study is to present our experience on various endovascular treatment modalities of basilar fenestration aneurysms and reviewing our findings together with literature data.

Materials And Methods: A total of 26 basilar artery fenestration (BAF) aneurysms in 24 patients were endovascularly treated in two different neurointerventional radiology clinics. All patients had been evaluated with computed tomography (CT), CT angiography, and digital subtraction angiography before the procedure.

A unique feature of the flow-diverting stent (FDS) has rendered it useful in the endovascular treatment of selected intracranial aneurysms for the last decade. Delayed aneurysmal rupture and intracranial parenchymal bleeding are two leading hemorrhagic complications after FDS. It has recently been shown for the first time that there is a relationship between FDS and reduced level of vWF activity in patients undergoing endovascular cerebral aneurysm treatment.

Craniocervical arterial dissection is an important cause of arterial ischemic stroke in children. Recognition of dissections is of particular importance both in determining the risk of recurrence and in bringing about different treatment alternatives. We report a 10-year-old girl who presented with acute ischemic stroke due to spontaneous long segment dissection involving the parasellar internal carotid artery up to the distal M1 portion of the middle cerebral artery.

Background And Purpose: Vascular devices generating high shear stress can cause type 2A acquired von Willebrand disease, which is characterized by low von Willebrand factor activity accompanied by hemorrhagic complications. The braided mesh structure of flow-diverting stents with a relatively small strut size can create abnormally high shear stress while arterial blood flows through the stent struts into the aneurysm, and flow-diverting stent may be associated with reduced von Willebrand factor activity.

Materials And Methods: Aneurysmal morphologic parameters and patient data were examined retrospectively among patients who had an unruptured intracranial aneurysm treated with a flow-diverting stent.

Spinal dural arteriovenous fistula (SDAVF) is the most common type of spinal vascular malformation. The main purpose of endovascular treatment is to occlude the fistula site and the proximal part of the draining vein. However, this is not always possible because of the difficulty of selective catheterization in patients with tortuous feeding arteries, as well as the risk of reflux of the liquid embolic agent.

Purpose: The aim of this study was to determine whether half-dose loading (30 mg) of prasugrel is sufficient to achieve adequate platelet inhibition, and whether such a loading dose of prasugrel together with aspirin followed by a 10 mg/day prasugrel maintenance, could serve as a first-line antiplatelet strategy for patients undergoing flow-diverting stent (FDS) implantation.

Methods: Data from a group of consecutive patients treated for intracranial aneurysm with FDS were retrospectively collected. Platelet P2Y12 receptor responsiveness was assessed by a rapid platelet function test just prior to the procedure.

Background And Purpose: Serpentine aneurysms are partially thrombosed aneurysms with an eccentrically located tortuous intra-aneurysmal vascular channel. The large size, distinctive neck anatomy, and supply of the brain parenchyma by the outflow tract pose technical challenges in treatment. The aim of this study was to discuss the endovascular treatment results and illustrate the dynamic nature of serpentine aneurysms.

Ischemia-modified albumin (IMA) is assumed "N-terminal modified" albumin which is generated immediately following myocardial ischemia. The diagnosis of IMA is based on reduced cobalt binding affinity to albumin which is attributed mainly to incapability of cobalt to bind at albumin's modified N-terminus. Although the albumin cobalt binding test was accepted as a potentially powerful marker for discriminating acute coronary syndrome from nonischemic chest pain, its usefulness has been brought into question in recent years.

Aim: Eagle syndrome is a rare entity that causes recurrent throat pain, neck pain, dysphagia, or facial pain due to an elongated styloid process or calcified stylohyoid ligament. Clinical findings related to lower cranial nerve compression have also been reported. In some cases, it is reported that carotid artery compression or dissection can be seen due to elongated styloid process and this is called carotid artery syndrome.
