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 ...

The Impact of Early Postoperative Blood Pressure Variability and Hypertension Status on 90‐Day Functional Outcomes in Acute Ischemic Stroke due to Large Vessel Occlusion Patients Treated With Mechanical Thrombectomy

AGING MEDICINE, EarlyView.
Early postoperative blood pressure variability independently predicts poor 90‐day functional outcomes in AIS‐LVO patients after mechanical thrombectomy, with the adverse effect amplified in those with pre‐existing hypertension. Maintaining stable blood pressure in the early postoperative period may improve recovery in this high‐risk population ABSTRACT

Comparison of Intracranial Hemorrhage and Clinical Outcomes Among Patients Undergoing Mechanical Thrombectomy with and without Thrombolytic Therapy [PDF]

Aim: It remains controversial whether intravenous tissue plasminogen activator (IV tPA) increases complications in patients undergoing mechanical thrombolysis. In this study, we aimed to show the effect of IV tPA administration on complications. Methods:

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

A Steerable and Expandable Magnetic Aspiration Catheter for Enhanced Aspiration Thrombectomy

Advanced Intelligent Systems, EarlyView.
This article presents a novel magnetic aspiration catheter (MAC) that can be both actively steered and undergo distal‐end expansion via externally applied magnetic fields. The MAC facilitates precise branch selection and enhances clot engagement by improving endovascular navigation and aspiration efficiency. Phantom experiments validate its feasibility

Comparative study on treatment of acute cerebral infarction between mechanical thrombectomy by micro catheter and thrombectomy by Solitaire AB stent

Medicine, 2022
. Background:. Acute cerebral artery occlusion is a common disease with high morbidity and mortality. At present, the commonly used mechanical thrombectomy schemes are mechanical thrombectomy and stent thrombectomy.

Update on Mechanical Thrombectomy [PDF]

Journal of Neurology & Neurophysiology, 2015
Intra-arterial stroke therapy aims to restore perfusion of the distal arterial bed by recanalizing the primary arterial occlusive lesion [1]. Successful recanalization positively correlates with improved longterm functional outcomes [2-4]. The PROACT II4 trial published in 1999 demonstrated a clear benefit from administering prourokinase via a catheter-

Mechanical Thrombectomy for Stroke After Cardiac Surgery

, 2016
Stroke after cardiac surgery remains a devastating complication and its treatment options are limited. Systemic fibrinolysis is a relative contraindication, because it raises the risk of systemic hemorrhage. Endovascular therapy, mechanical thrombectomy,

Molecular mechanism of ischemic postconditioning in promoting diabetic ischemic brain injury repair via the microRNA‐34a–BDNF–SIX3 signaling axis

Animal Models and Experimental Medicine, EarlyView.
Diabetes combined with ischemic stroke (DMIS) exacerbates brain infarct size and neuronal damage compared to nondiabetic ischemic stroke (IS). This study reveals that microRNA‐34a (miR‐34a) plays a key role in DMIS pathogenesis: miR‐34a directly targets and suppresses brain‐derived neurotrophic factor (BDNF) and Sine oculis homeobox 3 (SIX3), promoting
