Aim: To find clinical criteria applied in the first hours of disease for the identification of severe ischemic stroke caused by an occlusion of proximal major arteries.
Material And Methods: The authors have analyzed 133 medical histories of patients with the diagnosis of acute cerebral blood circulation disorder admitted in the first 6 h from onset. All patients underwent CT-angiography or digital subtraction angiography. Occlusion of the inner carotid artery, occlusion of M1-segment of the middle cerebral artery and occlusion of a major artery were considered as proximal occlusion of major cerebral arteries. Neurological status was assessed by the signs of proximal arterial occlusion (PAO).
Results And Conclusion: Checking of 5 PAO symptoms allows the prediction of occlusion location in approximately 80% of cases. Presence of ≥3 out of 5 symptoms is characterized by 70% sensitivity and 90% specificity with regard to the occlusion of the inner carotid artery, M1-segment of the middle cerebral artery and/or a major artery. Predictive value of this model should be verified in a prospective study.

Magnetic resonance angiography in diagnostic long-term follow-up of primary patency of the MOTIV drug-eluting bioresorbable vascular scaffold in the region below the knee: 5 years of experience.

Purpose: Treatment of peripheral artery disease (PAD) in the region below the knee (BTK) is dissatisfying as failure of treated target lesions (TLF) is frequent and diagnostic imaging is often challenging. In the BTK-region metallic drug-eluting stents (mDES) yielded best results concerning primary patency (PP), but also annihilate signal in magnetic resonance angiography (MR-A). A recently introduced non-metallic drug eluting bioresorbable Tyrocore® vascular scaffold (deBVS), that offers an option for re-treatment of lesions due to its full degradation within 3-4 years after placement, was investigated with respect to its compatibility with MR-A to unimpededly depict previously treated target lesions.

This first-in-man (FIM) study evaluated the feasibility and safety of a new peripheral plaque atherectomy system in patients with symptomatic lower extremity artery disease (LEAD). Ten patients with symptomatic LEAD (Rutherford class 2-5) were enrolled in a prospective, single-center study from March to April 2024. Patients aged 18-85 years with target lesions showing ≥70% stenosis and reference vessel diameters ≥1.

Background: Intravascular imaging (IVI) is widely recognized to improve outcomes after percutaneous coronary intervention (PCI). However, IVI is underutilized and is not yet established as a performance measure for quality PCI.
Methods: We examined temporal trends of IVI use for all PCIs performed at Veterans Affairs hospitals in the United States from 2010 to 2022 using retrospective observational cohorts.

Ischemic stroke is one of the major emergency diseases leading to death and disability worldwide, characterized by its acute onset and the urgent need for prompt medical intervention to reduce mortality and long-term disability. Chronic terminal internal carotid artery and/or middle cerebral artery occlusion (CTI/MCAO) is an important subtype of intracranial artery occlusive disease. The superficial temporal artery-to-MCA (STA-MCA) bypass has been proposed to improve cerebral blood flow (CBF) and cerebrovascular reserve (CVR), potentially enhancing neurological outcomes.

Purpose: The aim of our study was to assess the mid-term efficacy and safety of the FRED X flow diverting stent (FDS) in the treatment of intracranial aneurysms. The FRED X FDS is relatively new with limited data on its longer-term effectiveness and safety profile.
Methods: Patients with intracranial aneurysms treated with the FRED X FDS at two UK centres, between March 2021 and July 2022 with at least 18 months follow-up, were retrospectively reviewed.
