Balloon-mounted versus self-expandable stent in failed neurothrombectomy: a post hoc analysis of the SAINT study.
J Neurointerv Surg
January 2025
Department of Neurology, Emory University School of Medicine, Atlanta, Georgia, USA
Background: Previous studies have shown that when thrombectomy has failed, rescue intracranial stenting is associated with better clinical outcomes compared with failed reperfusion. However, comparative data regarding stent type are lacking.
Objective: To compare the procedural and clinical outcomes of balloon-mounted stents (BMS) with those of self-expandable stents (SES).
Background: Current guidelines recommend transcatheter aortic valve implantation (TAVI) for patients with aortic stenosis and porcelain aorta (PA). Neurological outcomes of patients with PA undergoing TAVI with modern valves require clarification as most trials examined balloon-expandable valves (BEV) and self-expandable valves in intermediate or high-risk patients, but not specifically in patients with PA. Our aim was to compare outcomes, including stroke and mortality, in well-matched patients with and without PA who received BEV during transfemoral TAVI procedures.

Purpose: To evaluate changes in non-target hepatic hemangiomas, which are neither subjected to embolization nor targeted for treatment, following selective bleomycin-lipiodol transarterial chemoembolization (TACE) of a giant hepatic hemangioma.
Materials And Methods: This single-center retrospective study included 24 patients with non-target hepatic hemangiomas distinct from primary giant hemangiomas treated with selective bleomycin-lipiodol TACE between 2009 and 2022. The size and volume of the lesions were assessed using computed tomography scans obtained before treatment, and at 6, 12 and 24 months.
Cervical sympathetic paraganglioma: A rare case managed with embolization and surgery with successful nerve recovery.

Introduction And Importance: Sympathetic paragangliomas are rare neuroendocrine tumors arising from the sympathetic nervous system.
Case Presentation: We present a case of a 48-year-old woman with an extremely rare paraganglioma arising from the cervical sympathetic chain that was presented to the emergency department with symptoms of respiratory insufficiency and dysphagia. Imaging revealed a highly vascularized tumor originating from the jugular fossa.
Multimodal Artificial Intelligence Model for Prediction of Abdominal Aortic Aneurysm Shrinkage After Endovascular Repair ( the ART in EVAR study).
J Endovasc Ther
January 2025
Department of Vascular Surgery, Rijnstate, Arnhem, The Netherlands.
Purpose: The goal of the study described in this protocol is to build a multimodal artificial intelligence (AI) model to predict abdominal aortic aneurysm (AAA) shrinkage 1 year after endovascular aneurysm repair (EVAR).
Methods: In this retrospective observational multicenter study, approximately 1000 patients will be enrolled from hospital records of 5 experienced vascular centers. Patients will be included if they underwent elective EVAR for infrarenal AAA with initial assisted technical success and had imaging available of the same modality preoperatively and at 1-year follow-up (CTA-CTA or US-US).
