Cerebral Venous-Sinus Thrombosis: A Case Series Analysis [PDF]

Iranian Journal of Medical Sciences, 2011
Background: Cerebral venous-sinus thrombosis is an uncommon form but important cause of stroke, especially in young-aged women. Methods: We performed a retrospective descriptive-analytical study in which 124 patients with cerebral venous-sinus thrombosis,

Safety and Efficacy of Single Femoral Vein Puncture Technique for Double Access in Patent Foramen Ovale Closure Under ICE Guidance—A Single Center Experience of the “Two‐In‐One Technique”

Catheterization and Cardiovascular Interventions, Volume 105, Issue 6, Page 1427-1433, May 1, 2025.
ABSTRACT Background In selected patient populations, percutaneous closure of patent foramen ovale has been shown to be beneficial in preventing cerebral ischaemic events. In most cases, this procedure requires echocardiographic guidance, which may be transesophageal, transthoracic or intracardiac.

Robot-Assisted Deep Venous Thrombosis Ultrasound Examination using Virtual Fixture [PDF]

Deep Venous Thrombosis (DVT) is a common vascular disease with blood clots inside deep veins, which may block blood flow or even cause a life-threatening pulmonary embolism. A typical exam for DVT using ultrasound (US) imaging is by pressing the target vein until its lumen is fully compressed. However, the compression exam is highly operator-dependent.

Cerebral venous thrombosis: a descriptive multicenter study of patients in Pakistan and Middle East [PDF]

, 2008
Background and Purpose: The natural history, causative factors, and outcomes of patients with cerebral venous thrombosis from Asia and Middle East have not been well described. This descriptive multicenter study describes the results for cerebral venous

Interleaved flow‐sensitive dephasing (iFSD): Toward enhanced blood flow suppression and preserved T1 weighting and overall signals in 3D TSE‐based neuroimaging

Magnetic Resonance in Medicine, Volume 93, Issue 5, Page 1911-1923, May 2025.
Abstract Purpose To develop and validate a 3D turbo spin‐echo (TSE)–compatible approach to enhancing black‐blood (BB) effects while preserving T1 weighting and overall SNR. Methods Following the excitation RF pulse, a 180° RF pulse sandwiched by a pair of flow‐sensitive dephasing (FSD) gradient pulses in the phase‐ (y) and partition‐encoding (z ...

Imitation Learning for Robotic Assisted Ultrasound Examination of Deep Venous Thrombosis using Kernelized Movement Primitives [PDF]

Deep Vein Thrombosis (DVT) is a common yet potentially fatal condition, often leading to critical complications like pulmonary embolism. DVT is commonly diagnosed using Ultrasound (US) imaging, which can be inconsistent due to its high dependence on the operator's skill.

Uncertainty quantification of a thrombosis model considering the clotting assay PFA-100 [PDF]

arXiv, 2021
Mathematical models of thrombosis are currently used to study clinical scenarios of pathological thrombus formation. Most of these models involve inherent uncertainties that must be assessed to increase the confidence in model predictions and identify avenues of improvement for both thrombosis modeling and anti-platelet therapies.

Idiopathic Intracranial Hypertension in Pregnancy. A Systematic Review on Clinical Course, Treatments, Delivery and Maternal‐Fetal Outcome

European Journal of Neurology, Volume 32, Issue 5, May 2025.
ABSTRACT Background Idiopathic intracranial hypertension (IIH) during pregnancy presents significant challenges due to the physiological gestational changes, which can exacerbate its symptoms. Methods We conducted a systematic review on studies reporting maternal‐fetal outcomes of IIH during pregnancy, selecting 49 papers reporting on clinical course ...

Ultrafast ultrasound coded vector Doppler imaging of blood flow velocity and resistivity [PDF]

S. Yan, Y. Ding, G. Ma, Y. Fu, K. Xu, and D. Ta, Ultrafast Ultrasound Coded Vector Doppler Imaging of Blood Flow Velocity and Resistivity, Acta Physica Sinica, vol. 74, no. 1, 2025
Dynamic and precise measurement of cerebral blood flow velocity is crucial in neuroscience and the diagnosis of cerebrovascular diseases. Traditional color Doppler ultrasound can only measure the velocity component along the ultrasound beam, which restricts its ability to accurately capture the complete blood flow vector in complex environments.
