A Safety and Feasibility Single-Arm Study of a Novel Catheter Thrombectomy Device for the Treatment of Pulmonary Embolism (ENGULF).

Background: Despite advances in therapy options, pulmonary embolism (PE) continues to carry a high risk of mortality and morbidity. Currently, therapeutic options are limited with only 2 US Food and Drug Administration-cleared catheter-based embolectomy devices approved for the treatment of intermediate-risk PE. The novel Hēlo PE thrombectomy catheter (Endovascular Engineering, Inc) has a flexible and collapsible funnel with an internal agitator for a dual mechanism of treatment for acute PE.

Moisture Content Prediction in Polymer Composites Using Machine Learning Techniques.

The principal objective of this study is to employ non-destructive broadband dielectric spectroscopy/impedance spectroscopy and machine learning techniques to estimate the moisture content in FRP composites under hygrothermal aging. Here, classification and regression machine learning models that can accurately predict the current moisture saturation state are developed using the frequency domain dielectric response of the composite, in conjunction with the time domain hygrothermal aging effect. First, to categorize the composites based on the present state of the absorbed moisture supervised classification learning models (i.

SCAI Position Statement on Best Practices for Percutaneous Axillary Arterial Access and Training.

Axillary artery access has become increasingly widespread as an alternative to the femoral route for large-bore transcatheter aortic valve replacement (TAVR), endovascular aortic repair (EVAR), and mechanical circulatory support (MCS) procedures. Advantages of percutaneous access include avoidance of a surgical incision, general anesthesia, and conduit graft infection. This statement aims to review the anatomic considerations and risks for percutaneous axillary artery access, suggest best practices for access techniques, hemostasis/closure strategies, and complication management, and recommend options for training and privileging.

Outcomes of Stroke Thrombectomy Performed by Interventional Radiologists versus Neurointerventional Physicians.

Purpose: To test the hypothesis that interventional radiologists (IRs) and neurointerventional (NI) physicians have similar outcomes of endovascular stroke thrombectomy (EVT), which could be used to improve the availability of thrombectomy.

Materials And Methods: Eight hospitals providing EVT performed by IRs and NI physicians at the same institution submitted sequential retrospective data limited to the era of modern devices. Good clinical outcomes (a 90-day modified Rankin score [mRS] of 0-2) and technically successful revascularization (a modified thrombolysis in cerebral infarction score of ≥2b) were compared between the specialties after adjusting for treating hospital, patient age, stroke severity, Alberta stroke program early computed tomography score, time from symptom onset to door, and clot location.
