Magnetic Milli‐Spinner for Robotic Endovascular Surgery

Advanced Materials, EarlyView.
The magnetic milli‐spinner, with its unique structural design, achieves rapid and stable navigation through complex vasculature at speeds up to 23 cm·s−1. It further enables multifunctional treatment, including localized suction and shear for efficient clot removal, targeted drug delivery, and in situ embolization for aneurysm therapy, establishing it ...

Posterior Circulation Mechanical Thrombectomy through Primitive Trigeminal Artery: A Case Report

Case Reports in Neurology
Introduction: Primitive trigeminal artery (PTA) is a rare intracranial vascular malformation, and mechanical thrombectomy and revascularization via PTA are rarely reported. Case Presentation: We reported a case of mechanical thrombectomy through PTA in a

Paradoxical pulmonary artery systolic pressure response with catheter-directed therapies for pulmonary embolism

American Heart Journal Plus, 2023
Background: Early data on use of catheter-directed therapies (CDT) for treatment of Intermediate or High-Risk pulmonary embolism (PE) show improvement in pulmonary artery systolic pressures (PAsP) and RV/LV ratios. Occasionally a paradoxical rise in PAsP

Suction force-suction distance relation during aspiration thrombectomy for ischemic stroke: A computational fluid dynamics study [PDF]

, 2016
Acute Ischemic Stroke (AIS) is the major type of stroke occurring in patients. Aspiration thrombectomy, which uses suction to remove the thrombosis, is a promising technique in the clinical treatment of AIS patients.

Subarachnoid Hemorrhage in Mechanical Thrombectomy for Acute Ischemic Stroke: Analysis of the STRATIS Registry, Systematic Review, and Meta-Analysis

Frontiers in Neurology, 2021
Background: The indications for mechanical thrombectomy in acute ischemic stroke continue to broaden, leading neurointerventionalists to treat vessel occlusions at increasingly distal locations farther in time from stroke onset.

Iron Overload Mediates the Differential Cell Fate of Astrocytes from Neurons and Its Regulatory Mechanisms in Ischemic Stroke

Advanced Science, EarlyView.
Upon ischemia/reperfusion‐induced iron overload condition, neurons and astrocytes exhibit similar oxidative stress changes but opposite alterations in endogenous antioxidant defense mechanisms, leading to divergent ferroptotic outcomes. The iron deposition and neuronal loss are increased within the perilesional cortex of stroke patients ...

Limb salvage using Pounce LP mechanical thrombectomy system after failed open and percutaneous thromboembolectomy

Journal of Vascular Surgery Cases and Innovative Techniques
Mechanical thrombectomy devices have limited efficacy in organized subacute and chronic thrombi and face challenges in small-caliber distal vessels. The Pounce LP Thrombectomy System (Surmodics) is a fully percutaneous, purely mechanical thrombectomy ...

High White Blood Cell Count Is a Risk Factor for Contrast-Induced Nephropathy following Mechanical Thrombectomy for Acute Ischemic Stroke

Cerebrovascular Diseases Extra, 2020
Background: Although mechanical thrombectomy is a standard endovascular therapy for patients with acute ischemic stroke (AIS), the incidence of and risk factors for contrast-induced nephropathy (CIN) following mechanical thrombectomy are infrequently ...
