A vascular synthetic model for improved aneurysm segmentation and detection via Deep Neural Networks [PDF]

arXiv
We hereby present a full synthetic model, able to mimic the various constituents of the cerebral vascular tree: the cerebral arteries, the bifurcations and the intracranial aneurysms. By building this model, our goal was to provide a substantial dataset of brain arteries which could be used by a 3D Convolutional Neural Network (CNN) to either segment ...

The role of atherosclerosis in HIV‐associated vasculopathy in young South African stroke patients

HIV Medicine, Volume 26, Issue 4, Page 633-642, April 2025.
Abstract Background HIV‐associated vasculopathy is known to cause stroke in people living with HIV (PLWH). The role of atherosclerosis is unclear. We assessed the aetiology of vasculopathy in PLWH and tested the utility of markers of subclinical atherosclerosis to distinguish atherosclerotic (AV) from non‐atherosclerotic vasculopathy (NAV).

MoSt-DSA: Modeling Motion and Structural Interactions for Direct Multi-Frame Interpolation in DSA Images [PDF]

arXiv
Artificial intelligence has become a crucial tool for medical image analysis. As an advanced cerebral angiography technique, Digital Subtraction Angiography (DSA) poses a challenge where the radiation dose to humans is proportional to the image count. By reducing images and using AI interpolation instead, the radiation can be cut significantly. However,

Superwide Left Atrial Circumferential Ablation for Persistent Atrial Fibrillation: A Randomized Controlled Trial

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background It remains to be answered whether further enlargement of the isolation area in the left atrium (LA) could produce better effectiveness than pulmonary vein antrum isolation (PVAI) for treatment of atrial fibrillation (AF). Aims To assess the effectiveness of superwide left atrial circumferential ablation (SWLACA) for treatment of ...

Nomogram for Deep Vein Thrombosis Prediction Post‐Endovascular Thrombectomy in Acute Ischemic Stroke: A Retrospective Multicenter Observational Study

Journal of Clinical Nursing, EarlyView.
ABSTRACT Background Deep vein thrombosis (DVT) is a frequent complication following endovascular thrombectomy (EVT) in patients with acute ischaemic stroke (AIS), potentially leading to fatal pulmonary embolism (PE). Identifying patients early at high risk for DVT is clinically important.

Automated Registration of 3D Neurovascular Territory Atlas to 2D DSA for Targeted Quantitative Angiography Analysis [PDF]

arXiv
Subarachnoid hemorrhage (SAH), typically due to intracranial aneurysms, demands precise imaging for effective treatment. Digital Subtraction Angiography (DSA), despite being the gold standard, broadly visualizes cerebral blood flow, potentially masking key details in areas.

The causative role of amyloidosis in the cardiac complications of Alzheimer's disease: a comprehensive systematic review

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustration of the bidirectional causative link between cerebral amyloid‐beta (Aβ) angiopathy and cardiovascular disease in Alzheimer's disease (AD). Common cardiovascular risk factors like microvascular thrombosis, diabetes, atrial fibrillation, hypertension and atherosclerosis lead to cerebral hypoperfusion and ...

Cerebral blood flow during simulated central hypovolaemia in people with hypertension: does vertebral artery hypoplasia matter?

The Journal of Physiology, Volume 603, Issue 6, Page 1417-1437, 15 March 2025.
Abstract figure legend Participants with hypertension underwent magnetic resonance angiography (MRA) during central hypovolaemia induced by lower body negative pressure (LBNP). Participants were assigned to a group with vertebral artery hypoplasia (VAH; n = 13) or without VAH group (n = 11) post‐acquisition.
