Background And Purpose: As flow diversion (FD) is becoming increasingly important in the endovascular treatment of intracranial aneurysms, the rate of technical complications is also increasing. Inadequate FD implantation may lead to both ischemic complications and decreased treatment efficacy. The aim of this study was to evaluate the efficacy of off-label stent retriever (SR) use in managing technical complications associated with FD implantation.

Bleeding is usually attributed to arterial feeders arising from the anterior spinal artery (ASA) and aneurysms located on such feeders. Perimedullary AVFs are typically found on the ventral surface of the spinal cord, which makes them difficult to treat through traditional microsurgical methods.

- Pediatric intracranial aneurysms are rare and require specialized diagnosis and treatment, as highlighted by a case of a child with a thrombosed dissecting aneurysm in the middle cerebral artery that needed emergency microsurgery.
- The treatment involved aneurysm trapping, decompression, and revascularization through a less invasive minipterional craniotomy, which was successful despite a later occlusion of the bypass after one year, leaving the patient asymptomatic.
- Key takeaways stress the importance of immediate intervention for unstable vascular lesions and the effectiveness of a multidisciplinary approach in managing complex cases in children.
Background: Emerging evidence suggests that endovascular thrombectomy is beneficial for treatment of childhood stroke, but the safety and effectiveness of endovascular thrombectomy has not been compared with best medical treatment. We aimed to prospectively analyse functional outcomes of endovascular thrombectomy versus best medical treatment in children with intracranial arterial occlusion stroke.
Methods: In this prospective registry study, 45 centres in 12 countries across Asia and Australia, Europe, North America, and South America reported functional outcomes for children aged between 28 days and 18 years presenting with arterial ischaemic stroke caused by a large-vessel or medium-vessel occlusion who received either endovascular thrombectomy plus best medical practice or best medical treatment alone.
Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare but severe complication following vaccination with adenovirus vector-based COVID-19 vaccines. Antibodies directed against platelet factor 4 (PF4) are thought to be responsible for platelet activation and subsequent thromboembolic events in these patients. Since a single vaccination does not lead to sufficient immunization, subsequent vaccinations against COVID-19 have been recommended.
