Aim: To investigate the safety and efficacy of Derivo® embolisation device (DED), a new-generation flow diverter designed to treat cerebrovascular aneurysms, and its long-term clinical outcomes.
Material And Methods: In total, 146 patients with 182 aneurysms were treated with DED. The mean age of the participants was 51.5 years; among them, 46 (31.5%) presented with acute subarachnoid haemorrhage. The mean aneurysm size was 8.3 mm, and 12 aneurysms were involved the vertebrobasilar system. Ophthalmic aneurysms account for most internal carotid artery (ICA) aneurysms.
Results: The Glasgow Coma Scale (GCS) score of 12 patients was < 15. DED was associated with a mortality rate of 2.7% and permanent morbidity rate of 3.4%, and a complete aneurysm occlusion rate was achieved in 78.7% of cases after 7.02 months.
Conclusion: The DED device is a new-generation flow diverter with excellent opening behaviour and navigational benefits. Our results indicated a safe aneurysm occlusion with optimum morbidity and mortality values despite the fact that almost one-third of the patients presented with subarachnoid haemorrhage.

Introduction: The efficacy and safety of statins for secondary prevention in patients who have experienced a cardioembolic stroke are not well-defined. However, previous observational data reported hyperlipidemia as a risk factor for both ischemic and bleeding complications in patients with AF and previous stroke. Based on these premises, we conducted a sub-analysis of the RAF and RAF-NOAC studies to evaluate the efficacy and safety of statins in secondary prevention in patients with acute ischemic stroke and AF.

The prevailing belief is that third-generation tyrosine kinase inhibitors (TKIs) targeting the epidermal growth factor receptor (EGFR) (TGET) outperform first-generation EGFR-TKIs (FGET) in managing advanced-stage EGFR-mutated non-small cell lung cancer (NSCLC). However, this standpoint lacks substantiation in evidence-based medicine. Therefore, this meta-analysis was conducted to compare the efficacy and adverse effects (AEs) of these two categories.

Atrial septal defects are among the most prevalent congenital anomalies necessitating surgical intervention. Thrombus formation is a recognized complication that is typically characterized by an embolic event following patch-based repair. However, thromboembolic complications following primary repair of atrial septal defects are exceedingly uncommon.

The mediastinal vasculature can be affected by various etiologies in cancer patients. Both direct and indirect sequela of cancer may result in life-threatening clinical presentations. Tumor growth may cause vessel narrowing and decreased blood flow from either extrinsic mass effect, invasion into the vascular wall, or tumor thrombus within the lumen.

Ectopic varices can result from portal vein stenosis following pancreaticoduodenectomy with concomitant portal vein resection reconstruction, and they can cause gastrointestinal bleeding. Although they can sometimes be fatal, various treatments have been reported. This report describes a case in which a percutaneous transhepatic approach was used to simultaneously perform variceal embolization and portal vein stenting in which a favorable outcome was achieved.
