Ultrastructural Analysis of Volumetric Histotripsy Bio-effects in Large Human Hematomas.

Ultrasound Med Biol 2021 Jun 8. Epub 2021 Jun 8.

Laboratory for Industrial and Medical Ultrasound, Physics Faculty, M. V. Lomonosov Moscow State University, Moscow, Russian Federation; Center for Industrial and Medical Ultrasound, Applied Physics Laboratory, University of Washington, Seattle, Washington, USA.

Large-volume soft tissue hematomas are a serious clinical problem, which, if untreated, can have severe consequences. Current treatments are associated with significant pain and discomfort. It has been reported that in an in vitro bovine hematoma model, pulsed high-intensity focused ultrasound (HIFU) ablation, termed histotripsy, can be used to rapidly and non-invasively liquefy the hematoma through localized bubble activity, enabling fine-needle aspiration.

Clinical imaging factors of excellent outcome after thrombolysis in large-vessel stroke: a THRACE subgroup analysis.

Stroke Vasc Neurol 2021 Jun 8. Epub 2021 Jun 8.

Department of Neurology-Stroke Unit, CIC-P 1433, INSERMU1116, Université de Lorraine, Nancy Regional University Hospital Center, Nancy, France

Background: For patients with stroke with large-vessel occlusion (LVO), study of factors predicting response to intravenous thrombolysis (IVT) would allow identifying subgroups with high expected gain, and those for whom it could be considered as futile, and even detrimental. From patients included in the Mechanical Thrombectomy After Intravenous Alteplase vs Alteplase Alone After Stroke trial, we investigated clinical-imaging factors associated with optimal response to IVT.

Prediction of Early Recanalization after Intravenous Thrombolysis in Patients with Large-Vessel Occlusion.

J Stroke 2021 May 31;23(2):244-252. Epub 2021 May 31.

Department of Neurology, Yonsei University College of Medicine, Seoul, Korea.

Background And Purpose: We aimed to develop a model predicting early recanalization after intravenous tissue plasminogen activator (t-PA) treatment in large-vessel occlusion.

Methods: Using data from two different multicenter prospective cohorts, we determined the factors associated with early recanalization immediately after t-PA in stroke patients with large-vessel occlusion, and developed and validated a prediction model for early recanalization. Clot volume was semiautomatically measured on thin-section computed tomography using software, and the degree of collaterals was determined using the Tan score. Read More
