Recanalization of the Chronically Occluded Internal Carotid Artery: Review of the Literature. [PDF]

open access: yes, 2020
Introduction: We reviewed the literature on interventions for patients with medically refractory chronically occluded internal carotid artery (COICA) to assess the risks and/or benefits after recanalization via an endovascular technique (ET) or hybrid ...

Ischemic brain lesions after carotid artery stenting increase future cerebrovascular risk [PDF]

open access: yes, 2015
Background Brain lesions on diffusion-weighted imaging (DWI) are frequently found after carotid artery stenting (CAS), but their clinical relevance remains unclear.

Micro/Nanorobots for Combating Brain Disorders: Challenges, Advances, and Perspectives

open access: yesAdvanced Science, EarlyView.
Micro/nanorobots (MNRs) offer a transformative approach for precision therapy in brain disorders. By overcoming biological barriers and enabling controlled propulsion, targeted delivery, and real‐time imaging/tracking, MNRs pave the way toward effective, minimally invasive treatments. This review outlines the interplay between brain disease challenges,

Adjusting for bias introduced by instrumental variable estimation in the Cox Proportional Hazards Model

open access: yes, 2017
Instrumental variable (IV) methods are widely used for estimating average treatment effects in the presence of unmeasured confounders. However, the capability of existing IV procedures, and most notably the two-stage residual inclusion (2SRI) procedure ...

A Soft‐Tip Hydraulically Steerable Catheter for Enhanced Flexibility and Safety in Vascular Interventions

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a hydraulically steerable catheter with a soft tip in vascular procedures. The steering soft tip achieves a minimal diameter of 2.6 mm and supports a 180° bend. Real‐time shape and position tracking, facilitated by segmentation and endpoint detection techniques, improves navigation.

Clinical Studies Target Fewer Complications, Better Outcomes for Vascular Surgery [PDF]

open access: yes, 2017
Two studies at the Jefferson Vascular Center (JVC) are assessing innovative methods to reduce risk of complications — and increase positive outcomes — for vascular surgery patients. Here, Paul DiMuzio, MD, FACS, William M. Measey Professor of Surgery and

Acute administration of tirofiban versus aspirin in emergent carotid artery stenting

open access: yesInterventional Neuroradiology, 2018
Background Carotid artery stenting requires antiplatelet therapy for prevention of in-stent thrombosis. Patients suffering from acute ischemic stroke undergoing intravenous thrombolysis and emergent carotid artery stenting (eCAS) are at high risk for ...

Carotid Artery Stent Placement

open access: yesJACC: Cardiovascular Interventions, 2010
In the past 3 years, there have been significant developments in the field of carotid revascularization, including: 1) the results of a large primary stroke prevention trial; 2) the emergence of novel platforms for emboli protection; 3) improved characterization of the high-risk carotid artery stent (CAS) patient; 4) completion of several very large ...

Microendovascular Neural Recording from Cortical and Deep Vessels with High Precision and Minimal Invasiveness

open access: yesAdvanced Intelligent Systems, EarlyView.
Intravascular electroencephalography (ivEEG) using micro‐intravascular electrodes was developed. Cortical‐vein ivEEG showed a higher signal‐to‐noise ratio and finer spatial resolution of somatosensory evoked potentials (SEPs) than superior sagittal sinus ivEEG, and deep‐vein ivEEG captured clear visual evoked potentials.
