Optimal Endovascular Therapy Technique for Isolated Intracranial Atherothrombotic Stroke-Related Large-Vessel Occlusion in the Acute-to-Subacute Stage.

Background And Purpose: Reocclusion after treatment is a concern in endovascular therapy for isolated intracranial atherothrombotic stroke-related large-vessel occlusion (AT-LVO). However, the optimal endovascular therapy technique for AT-LVO has not yet been investigated. This study evaluated the optimal endovascular therapy technique for AT-LVO in a real-world setting.

Differences in mechanical thrombectomy for acute ischemic stroke on weekdays versus nights/ weekends in a Japanese primary stroke core center.

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.

Endovascular Therapy for an Aneurysm of a Distal Posterior Inferior Cerebellar Artery via the Ipsilateral Persistent Primitive Proatlantal Artery: A Case Report.

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.

Usefulness of three-dimensional fast imaging employing steady-state acquisition MRI of large vessel occlusion for detecting occluded middle cerebral artery and internal carotid artery before acute mechanical thrombectomy.

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.

Mechanical Thrombectomy for Large Vessel Occlusion via the Transbrachial Approach: Case Series.

Mechanical thrombectomy has become a standard treatment for acute ischemic stroke with large vessel occlusion. In aged patients, it is difficult to guide the catheter via the transfemoral approach due to vessel tortuosity and aortic elongation. We report our preliminary clinical experience using the transbrachial approach.

Parent Artery Occlusion for Treatment of a Traumatic Pericallosal Artery Aneurysm: Case Report and Review of the Literature.

Background: Traumatic intracranial aneurysms are rare complications after head trauma. This report describes the case of a patient with a traumatic pericallosal aneurysm.

Case Description: A 73-year-old man developed headache and lower limb paresis, and emergency computed tomography scan revealed a hematoma in the corpus callosum.

Clinical Outcomes of Mechanical Thrombectomy for Acute Ischemic Stroke in Transfer Cases.

Objective: There are regional disparities in endovascular thrombectomy, and problems with emergency transport systems and hospital collaboration when transferring need to be addressed. In this study, the clinical outcomes of endovascular thrombectomy for transferred patients were analyzed.

Methods: Acute ischemic stroke patients who underwent endovascular thrombectomy between January 2016 and March 2019 were enrolled.

Clinical Results of Mechanical Thrombectomy in Nonagenarians with Acute Ischemic Stroke.

Objective: Multiple randomized trials have demonstrated the efficacy of mechanical thrombectomy (MT), but very elderly patients aged ≥90 years were excluded. It remains uncertain whether endovascular therapy is effective for nonagenarians. The objective of this study was to investigate the effectiveness and safety of MT in nonagenarians.

Impact of Endovascular Therapy in Patients With Large Ischemic Core: Subanalysis of Recovery by Endovascular Salvage for Cerebral Ultra-Acute Embolism Japan Registry 2.

Background And Purpose: Endovascular therapy (EVT) is strongly recommended for acute cerebral large vessel occlusion with the Alberta Stroke Program Early CT Score (ASPECTS) ≥6 due to occlusion of the internal carotid artery or M1 segment of the middle cerebral artery. However, the effect of EVT for patients who have ischemic core with ASPECTS ≤5 (0–5) was not established. The purpose of this study was to elucidate the outcomes of EVT for patients with large ischemic core.
