Towards a Computed Collateral Circulation Score in Ischemic Stroke [PDF]

arXiv, 2020
Stroke is the second leading cause of disability worldwide. In order to minimize disability, the goal of stroke treatment is to preserve tissue in the area where blood supply is decreased but sufficient to stave off cell death. Thrombectomy has been shown to offer fast and efficient reperfusion with high recanalization rates.

Text2Struct: A Machine Learning Pipeline for Mining Structured Data from Text [PDF]

arXiv, 2022
Many analysis and prediction tasks require the extraction of structured data from unstructured texts. However, an annotation scheme and a training dataset have not been available for training machine learning models to mine structured data from text without special templates and patterns.

3D‐cultured BMSC exosomes improve cerebral ischemia/reperfusion injury‐induced neuronal apoptosis by regulating the microglia polarization

BMEMat, EarlyView.
The study reveals that microglial activation significantly contributes to neuroinflammation following cerebral ischemia‐reperfusion injury. It demonstrates that utilizing GelMA hydrogel for three‐dimensional culture of bone marrow‐derived mesenchymal stem cells (BMSCs) enhances the efficacy of BMSC‐derived exosomes in regulating microglial polarization

Post-operative neutrophil-to-lymphocyte ratio and outcome after thrombectomy in acute ischemic stroke

Frontiers in Neurology, 2022
BackgroundNeutrophil to lymphocyte ratio (NLR) is a novel inflammatory marker to predict adverse cardiovascular events. However, there is a lack of data on hemorrhagic transformation (HT) and neurological outcome after mechanical thrombectomy in acute ...

Towards clinical translation of deep-learning based classification of DSA image sequences for stroke treatment [PDF]

arXiv, 2023
In the event of stroke, a catheter-guided procedure (thrombectomy) is used to remove blood clots. Feasibility of machine learning based automatic classifications for thrombus detection on digital substraction angiography (DSA) sequences has been demonstrated. It was however not used live in the clinic, yet.

AI-based Agents for Automated Robotic Endovascular Guidewire Manipulation [PDF]

arXiv, 2023
Endovascular guidewire manipulation is essential for minimally-invasive clinical applications (Percutaneous Coronary Intervention (PCI), Mechanical thrombectomy techniques for acute ischemic stroke (AIS), or Transjugular intrahepatic portosystemic shunt (TIPS)).

Endovascular Treatment of Malfunctioning Dialysis Fistulas: A Multicenter Retrospective Analysis Comparing Transradial and Conventional Transvenous Access

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Venous outflow is the favored access for endovascular management of dialysis fistulas. However, transradial access (TRA) offers advantages in specific clinical scenarios. The study aims to compare the efficacy, feasibility, and safety of TRA and transvenous access (TVA) in the endovascular management of malfunctioning dialysis ...
