Objective: This study aimed to examine the effect of drug-coated balloons (DCBs) on vascular luminal dilatational remodeling (VLDR) following simple balloon angioplasty.
Methods: A retrospective cohort study was conducted using data from patients diagnosed with intracranial atherosclerotic stenosis (ICAS), who were treated exclusively with balloon angioplasty at Henan Provincial People's Hospital between June 2019 and April 2023. Inverse probability weighting (IPW) was used to create balanced cohorts of patients who underwent drug-coated balloon angioplasty (DCBA) and plain old balloon angioplasty (POBA).
Background: Patterns of arterial remodeling may be associated with outcomes in patients with severe middle cerebral artery (MCA) stenosis after endovascular treatment (EVT). This study aims to investigate the potential correlation between arterial remodeling patterns in patients with severe MCA stenosis, and plaque characteristics and procedure-related perforator stroke (PS).
Methods: Consecutive patients with MCA atherosclerotic disease who underwent EVT at the First Affiliated Hospital of Zhengzhou University from January 2018 to June 2023 were retrospectively enrolled in this study.
Background: In-stent restenosis (ISR) is a crucial factor that affects the long-term efficacy of intracranial bare metal stent (BMS) implantation for intracranial atherosclerotic stenosis (ICAS). Patients with intracranial ISR are at a high risk of recurrent ischaemic events. The NOVA intracranial drug-eluting stent (DES) trial demonstrates that a DES can reduce ISR and stroke recurrence after intracranial bare stent implantation.

We assessed the safety and efficacy of DCBs vs stent angioplasty for symptomatic intracranial atherosclerotic stenosis (sICAS) and initially identified patients who might have benefited most from DCB treatment.
Methods: A single-center, retrospective cohort study was conducted from June 2021 to May 2022 with 154 patients with sICAS divided into 2 treatment groups: a DCB group (with or without remedial stenting, n = 47) and a stent group (n = 107).
Magnesium alloy is an excellent material for biodegradable cerebrovascular stents. However, the rapid degradation rate of magnesium alloy will make stent unstable. To improve the biocompatibility of magnesium alloy, in this study, biodegradable sodium alginate and carboxymethyl chitosan (SA/CMCS) was used to coat onto hydrothermally treated the surface of magnesium alloy by a dipping coating method.

However, currently available cardiac DCBs are not always suitable for the treatment of intracranial atherosclerotic stenosis (ICAS). This study aimed to evaluate the safety and efficacy of a novel DCB catheter designed for patients with severely symptomatic ICAS.

We aimed to examine whether the symptomatic qualifying artery modifies the effect of stenting plus medical therapy.
Methods: This is a post-hoc analysis of the CASSISS trial that included patients with symptomatic intracranial stenosis, randomly assigned to undergo stenting plus medical therapy or medical therapy alone; 358/380 patients were included.
Objective: In the present study, we conducted a meta-analysis of reported randomized controlled trials (RCTs) comparing the safety and efficacy of direct thrombectomy (DT) and bridging therapy (BT) for patients eligible for intravenous thrombolysis (IVT).
Methods: A comprehensive search of PubMed, Cochrane Library, EMBASE, and Web of Science up to July 11, 2022 was performed. RCTs comparing DT and BT were included.
Background: Autophagy plays an important role in the progression of carotid atherosclerosis (CAS). This study aimed to identify hub autophagy-related genes (ATGs) associated with CAS.
Methods: GSE43292 and GSE28829 datasets of early and advanced CAS plaques were enrolled from the Gene Expression Omnibus (GEO) database.
Introduction: Brain arteriovenous malformation (bAVM) might have a higher risk of rupture after partial embolization, and previous studies have shown that some metrics of vascular stability are related to bAVM rupture risk.
Objective: To analyze vascular stability of bAVM in patients after partial embolization.
Methods: Twenty-four patients who underwent partial embolization were classified into the short-term, medium-term, and long-term groups, according to the time interval between partial embolization and surgery.
Background: Intracranial aneurysm (IA) is an uncommon but severe subtype of cerebrovascular disease, with high mortality after aneurysm rupture. Current risk assessments are mainly based on clinical and imaging data. This study aimed to develop a molecular assay tool for optimizing the IA risk monitoring system.

The purpose of this study was to evaluate the efficacy of the one-stop stroke management (OSSM) platform in reducing in-hospital workflow times in patients receiving thrombectomy compared with the traditional model.
Methods: The data of patients who received thrombectomy treatment through the OSSM platform and traditional protocol transshipment pathway were retrospectively analyzed and compared.
Background: Pipeline embolization devices (PEDs) have been increasingly used for the treatment of posterior circulation aneurysms.
Objective: To investigate the safety and efficacy of PED in the treatment of small to medium unruptured vertebral artery intracranial aneurysms (VAIAs).
Methods: Data from 76 patients with 78 unruptured small and medium (≤12 mm) VAIAs were analyzed.
Background: Drug-coated balloon (DCB) angioplasty has been studied for reducing the occurrence of restenosis after treatment for intracranial atherosclerotic stenosis (ICAS), but no comparison has been published of the use of drug-coated and non-coated balloons in angioplasty for ICAS. We aim to compare the safety and efficacy of DCB angioplasty with conventional balloon (CB) angioplasty for the treatment of symptomatic ICAS.
Methods: One hundred cases with symptomatic ICAS treated with DCB (n=49) and CB (n=51) angioplasty were retrospectively analyzed.
Background And Purpose: Stent retriever thrombectomy is the standard therapeutic approach for ischemic stroke with acute large-vessel occlusion. This study evaluated the safety and efficacy of a new thrombectomy device (Skyflow) in the treatment of acute ischemic stroke.
Methods: After an arterial occlusion model was established, stent-retriever thrombectomy was performed.
Background And Purpose: Tirofiban administration after mechanical thrombectomy (MT) remains controversial. This study aimed to investigate the efficacy and safety of adjunct tirofiban treatment following MT for acute ischemic stroke (AIS) patients with large vessel occlusion (LVO) that resulted in successful reperfusion on digital subtraction angiography (DSA).
Methods: This retrospective study was conducted in Zhengzhou University University People's Hospital, an advanced stroke center in China.
Objective: To evaluate the safety and efficacy of the SeparGate™ balloon-guiding catheter (BGC) for blocking flow and delivering devices in neurointerventional surgery.
Method: This prospective multicenter single-arm trial enrolled patients who received BGC adjuvant therapy to provide temporary blood flow arrest of the supra-aortic arch arteries and their branch vessels in interventional therapy. The primary endpoint was immediate procedural success rate in flow arrest, device delivery, and withdrawal.
Background: Diagnosed as a kind of vascular neoplasm of infancy, hemangioma (HA) occurs mainly due to the aberrant proliferation of endothelial cells. Existing evidence has manifested the close relationship of long noncoding RNAs (lncRNAs) with the pathogenesis of HA. Although lncRNA DSCAM antisense RNA 1 (DSCAM-AS1) has been revealed to be implicated in the progression of human diseases, the underlying mechanism DSCAM-AS1 exerts in HA formation is unclear.

The adjunctive use of balloon guide catheter (BGC) may increase the rates of the first-pass effect. In this retrospective study we examined the impact of BGC on the first-pass effect in acute stroke patients.
