Carotid artery stenting (CAS) has traditionally been performed using the transfemoral approach (TFA). Recently, the transradial approach (TRA) has gained attention for its lower invasiveness and reduced complication risk. This study compares outcomes between two access strategy timeframes, TFA-first and TRA-first, to evaluate how this shift influences outcomes in a real-world setting.

Article Synopsis
  • The study investigated the effect of administering P2Y inhibitors during endovascular treatment (EVT) in patients with anterior circulation thrombosis due to acute ischemic stroke.
  • Out of 242 patients analyzed, those who received P2Y inhibitors had a significantly higher rate of carotid artery stenting and better functional outcomes after 90 days compared to those who did not.
  • The results showed that patients treated with P2Y inhibitors had an adjusted odds ratio of 6.65 for better outcomes, suggesting a strong positive association with the use of these medications.

Background: Restenosis after carotid artery stenting (CAS) is associated with the risk of developing ischemic stroke. We aimed to evaluate the inhibitory effect of cilostazol addition on in-stent restenosis (ISR) in patients treated with CAS.

Methods: In a randomized, open-label, blind-end point trial, patients with symptomatic and asymptomatic carotid artery stenosis and scheduled for CAS were randomly assigned to adding cilostazol (50 or 100 mg, twice per day) on other antiplatelets from 3 days before CAS or not adding cilostazol.

Background: The addition of antiplatelet therapy to anticoagulant therapy in patients with stroke with non-valvular atrial fibrillation (NVAF) and atherothrombotic disease may increase bleeding risk without reducing recurrent stroke risk.

Aims: To evaluate the clinical benefits of anticoagulant monotherapy compared to combination therapy with anticoagulants and antiplatelet agents.

Methods And Design: This is an investigator-initiated prospective multicenter, randomized, open-label, parallel-group clinical trial.

Objective: Rupture of cerebral aneurysms has a poor prognosis, and growing aneurysms are prone to rupture. Although the number of coil embolization procedures is increasing worldwide, they are more prone to recurrence than clipping surgeries. However, there is still no drug that prevents aneurysm growth or recanalization after coil embolization.

Article Synopsis
  • This study evaluated the safety and effectiveness of the Versi Retriever for mechanical thrombectomy in patients suffering from acute ischemic stroke (AIS) at 10 hospitals in Japan.
  • It involved 58 patients, showing that 62% achieved a good recovery (mRS 0-2) after 90 days, and 100% had successful blood flow restoration.
  • The procedure had an 8% mortality rate within 90 days and a significant occurrence of intracranial hemorrhage, indicating that while effective, some risks are involved.

Article Synopsis
  • Endovascular treatment (EVT) shows promise for addressing extracranial vertebral artery (VA) stenosis, but optimal procedures and efficacy are still unclear.
  • A study analyzed data from 308 patients in Japan who underwent EVT, focusing on procedural success and outcomes at 30 days post-treatment.
  • Results indicated a high procedural success rate (98%) and functional independence (80%) without significant differences based on type of treatment used, highlighting EVT's potential but also the need for additional research.

Background And Objectives: Endovascular treatment (EVT) for medium vessel occlusion (MeVO) raises concern about hemorrhagic complications; however, its clinical impact has not been elucidated. Therefore, we investigated the association between intracranial hemorrhage (ICH) after EVT for MeVO and functional outcomes.

Methods: We conducted a post hoc analysis of the Japan Registry of NeuroEndovascular Therapy 4, a nationwide registry in Japan from 2015 to 2019 including 13 479 patients who underwent EVT for acute ischemic stroke.

Article Synopsis
  • * Results showed that AF patients had more severe initial strokes (higher NIHSS scores) and less favorable outcomes at discharge, although adjustments indicated some improvement for AF patients over time.
  • * Over the study period, AF patients experienced a noticeable decrease in stroke severity and an increase in favorable outcomes, suggesting that advances in stroke care benefits AF patients more than non-AF patients.

Article Synopsis
  • The study evaluated a new device called the Stabilizer, designed to enhance the safety and efficacy of neuroendovascular procedures that require exchanging medical instruments, which can be risky due to potential vessel injury.! -
  • Conducted across nine centers in Japan, the trial involved 31 patients with conditions like intracranial aneurysms and artery stenosis, with the Stabilizer achieving a 100% technical success rate and no device-related complications.! -
  • The findings of this first multicenter trial underscore the Stabilizer's potential as a reliable tool in managing complex neuroendovascular cases where traditional exchange methods might pose challenges.!

We reported the main results of the Japanese Registry of Neuroendovascular Therapy (JR-NET) 4, a nationwide surveillance of therapy (NET) in Japan from January 2015 to December 2019. JR-NET 4 registered consecutive patients who underwent NETs by Japan Society of Neuroendovascular Therapy (JSNET) -certified specialists. The primary endpoint was functional independence (mRS score of 0-2) at 30 days post-NET, with secondary endpoints focusing on technical success and major adverse events within 30 days.

Objective: Existing evidence is inconclusive on whether women after carotid artery stenting (CAS) experience worse outcomes than men.

Methods: The outcomes of women and men were compared using the data from nationwide retrospective registry between 2015 and 2019. The primary outcome was the incidence of ischemic stroke and all-cause death.

Introduction: The benefit of endovascular therapy (EVT) among stroke patients with large ischemic core (ASPECTS 0-5) in the extended time window outside of trial settings remains unclear. We analyzed the effect of EVT among these stroke patients in real-world settings.

Patients And Methods: The CT for Late Endovascular Reperfusion (CLEAR) study recruited patients from 66 centers in 10 countries between 01/2014 and 05/2022.

Objective: The term "weekend effect" refers to an increase in the mortality rate for hospitalizations occurring on weekends versus weekdays. In this study, we investigated whether such an effect exists in patients undergoing mechanical thrombectomy for acute ischemic stroke with large vessel occlusion (currently the standard treatment for this condition) at a single center in Japan.

Methods: We surveyed 151 patients who underwent mechanical thrombectomy for acute ischemic stroke with large vessel occlusion (75 and 76 patients were treated during daytime and nighttime, respectively) from January 2019 to June 2021.

Article Synopsis
  • The study investigates the relationship between signal intensity (SI) of the middle meningeal artery (MMA) and the recurrence of chronic subdural hematoma (CSDH) post-surgery.
  • It included 185 patients, finding that a higher SI ratio and a diagnosis of dementia were significant predictors for the recurrence of CSDH.
  • The research concluded that patients with a higher SI ratio on magnetic resonance angiography are more likely to experience a recurrence after surgery, allowing for the development of a risk score based on these findings.

Objective: We describe the rare case of a patient who was treated for a ruptured distal posterior inferior cerebellar artery (PICA) aneurysm via an ipsilateral persistent primitive proatlantal artery (PPPA).

Case Presentation: An 86-year-old female with a medical history of hypertension presented with headache and nausea. CT showed subarachnoid hemorrhage in the posterior cranial fossa, and CTA revealed an aneurysm at the left-side distal PICA.

Objective: Acute mechanical thrombectomy (AMT) in patients with acute ischemic stroke from large vessel occlusion (LVO) is performed without directly identifying the occluded vessels. In this study, we evaluated whether 1.5 T magnetic resonance imaging (MRI) with 3D-fast imaging employing steady-state acquisition (FIESTA) could visualize the occluded intracranial middle cerebral artery (MCA) and internal carotid artery (ICA) before AMT.
