Laboratory Assessment of Unfractionated Heparin (UFH) with Activated Clotting Time (ACT) and Anti-Xa Activity during Peripheral Arterial Angiographic Procedure

Diagnostics, 2023
Activated clotting time (ACT) is used in cardiac surgery for monitoring unfractionated heparin (UFH). In endovascular radiology, ACT use is less established. We aimed to test the validity of ACT in UFH monitoring in endovascular radiology.

Association Between Time to Treatment With Endovascular Reperfusion Therapy and Outcomes in Patients With Acute Ischemic Stroke Treated in Clinical Practice.

Journal of the American Medical Association (JAMA), 2019
Importance Randomized clinical trials suggest benefit of endovascular-reperfusion therapy for large vessel occlusion in acute ischemic stroke (AIS) is time dependent, but the extent to which it influences outcome and generalizability to routine clinical ...

PP2Acα Deficiency in Vascular Smooth Muscle Cells Accelerates Aortic Aneurysm and Dissection by Regulating KLF4 Phosphorylation and Ubiquitination

Advanced Science, EarlyView.
Vascular smooth muscle cells (VSMCs)‐specific deficiency of PP2Acα exacerbates aortic aneurysm and dissection (AAD) by promoting phenotypic switching through AKT1‐mediated phosphorylation and stabilization of Kruppel‐like factor 4 (KLF4). Reduced PP2Acα enhances KLF4 ubiquitination resistance, suppressing VSMC contractile genes and accelerating aortic ...

Deep Reinforcement Learning for the Navigation of Neurovascular Catheters

Current Directions in Biomedical Engineering, 2019
Endovascular catheters are necessary for state-ofthe- art treatments of life-threatening and time-critical diseases like strokes and heart attacks. Navigating them through the vascular tree is a highly challenging task. We present our preliminary results

Endovascular Neuromodulation: Safety Profile and Future Directions

Frontiers in Neurology, 2020
Endovascular neuromodulation is an emerging technology that represents a synthesis between interventional neurology and neural engineering. The prototypical endovascular neural interface is the StentrodeTM, a stent-electrode array which can be implanted ...

Limitations of Flow Diverters in Posterior Communicating Artery Aneurysms

Brain Sciences, 2021
Background: Treatment of intracranial aneurysms with flow diverters (FDs) showed promising results. However, a subset of patients treated for posterior communicating artery (PComA) aneurysms has variable occlusion rates.

Toward the Clinical Translation of Implantable Brain–Computer Interfaces for Motor Impairment: Research Trends and Outcome Measures

Advanced Science, EarlyView.
Implantable brain–computer interfaces (iBCIs) are rapidly approaching clinical translation. This review maps key trends in the development of iBCIs and highlights the lack of standardised clinical outcome measures. It discusses a proposed framework for the selection of outcome measures in clinical trials and introduces a new international registry of ...

A randomized trial comparing conventional and endovascular repair of abdominal aortic aneurysms.

New England Journal of Medicine, 2004
BACKGROUND Although the initial results of endovascular repair of abdominal aortic aneurysms were promising, current evidence from controlled studies does not convincingly show a reduction in 30-day mortality relative to that achieved with open repair.
