Comparative efficacy of urokinase and recombinant tissue-type plasminogen activators in intraventricular hemorrhage.

Objective: Spontaneous intracerebral hemorrhage (ICH) with intraventricular hemorrhage (IVH) is associated with high mortality and severe disability. This study aimed to compare the effects of urokinase-type plasminogen activator (uPA) and recombinant tissue-type plasminogen activator (r-tPA) on functional outcomes and IVH clearance in patients with IVH.

Methods: A retrospective analysis was conducted on 97 patients with IVH treated from January 2014 to February 2024.

Safety of antiplatelet medication discontinuation more than 12 months after stent-assisted coil embolization: a non-interventional, multicenter, observational study.

Background: Antiplatelet maintenance is essential to avoid ischemia following stent-assisted coiling (SAC) procedures. However, indications for antiplatelet medication discontinuation (AMD) remain controversial, and optimal timing of cessation has yet to be determined. Our goal, which we achieved through a multicenter, prospectively enrolled, non-interventional study, was to investigate the safety of AMD conducted more than 12 months after SAC.

Elevated Serum IL-6 as a Negative Prognostic Biomarker in Glioblastoma: Integrating Bioinformatics and Clinical Validation.

Glioblastoma multiforme (GBM) is the most lethal type of primary brain tumor, necessitating the discovery of reliable serum prognostic biomarkers. This study aimed to investigate the prognostic value of serum Interleukin-6 (IL-6) in GBM patients. Bioinformatics analysis via gene set enrichment analysis was conducted on The Cancer Genome Atlas RNA-seq data to explore the pathways enriched in samples with high expression.

The Potential Therapeutic Effects of Tadalafil on the Endothelium in a Subarachnoid Hemorrhage Animal Model: Insights from Immunohistochemical Staining.

This study investigated the potential of phosphodiesterase type 5 (PDE-5) inhibitors, specifically tadalafil, in preventing the delayed cerebral ischemia (DCI) post-rupture of cerebral aneurysms. A total of 19 rabbits were used in this study, divided into different treatment groups, including nimodipine alone, tadalafil alone, and a combination of nimodipine and tadalafil. Both nimodipine and tadalafil showed some impact on reducing endothelial apoptosis in the basilar arteries, although the effects were not statistically significant.

Coil embolization of the middle cerebral artery bifurcation aneurysms: Feasibility and durability.

Objective: To evaluate the feasibility and durability of coil embolization for MCAB aneurysms by analyzing clinical and radiological results.

Methods: From January of 2008 to June of 2018, we treated a total of 1785 aneurysms using coil embolization. The aneurysms were treated by both coiling and stent-assisted coiling.

Suction thrombectomy of distal medium vessel occlusion using microcatheter during mechanical thrombectomy for acute ischemic stroke: A case series.

While mechanical thrombectomy is known to be effective for distal medium vessel occlusion (DMVO) as well as large vessel occlusion, tortuous DMVO are predisposed to vessel injury during stent retriever thrombectomy. Furthermore, getting access to the thrombus may be difficult during suction thrombectomy using a dedicated suction catheter. Most studies describe DMVO treatment using stent retrievers and dedicated suction catheters, but there are limited studies reporting DMVO treated with suction thrombectomy using a microcatheter.

Distal stenting technique for coil embolization of early branch aneurysms of middle cerebral artery.

Background And Purpose: Stent-assisted coil embolization of early branch aneurysms of the middle cerebral artery (MCA) can sometimes be challenging due to the small diameter and acute angle of the branches. This study aimed to analyze the treatment results and report the feasibility and outcomes of the distal stenting technique for these aneurysms.

Materials And Methods: The distal stenting technique was used for 15 wide-neck MCA aneurysms (females, 10; males, 5; mean age, 65.

Endovascular recanalization therapy for patients with acute ischemic stroke with hidden aortic dissection: A case series.

Aortic dissection is one of the causes of acute ischemic stroke. Endovascular recanalization therapy (EVT) has emerged as an essential treatment for acute ischemic stroke due to large artery occlusion. However, it is rarely performed in the situation of hidden aortic dissection (AD).

Role of Adjunctive Tranexamic Acid in Facilitating Resolution of Chronic Subdural Hematoma after Surgery.

Objective: Chronic subdural hematoma (CSDH) is a common neurosurgical disease and generally treated with burr-hole surgery alone. Tranexamic acid (TXA) is an antifibrinolytic agent that potentially reduces recurrence rates and the residual hematoma volume. However, the role of postoperative TXA medication remains unclear to date.

Treatment results of anterior choroidal artery aneurysms treated mostly with coil embolization: A single-center experience.

Background: Anterior choroidal artery (AchA) aneurysms are usually small in diameter because of the size of the involved artery and are often wide-necked. Coil embolization of AchA aneurysm is thus challenging because of serious risks, such as thromboembolic occlusion of artery and perforation of aneurysm dome. Therefore, aneurysmal neck clipping remains widely performed despite a recent increase in the use of coil embolization for aneurysm treatment.

Endovascular coil embolization for unruptured intracranial aneurysms in patients over 80 years of age.

Objective: As the average life span in modern society continues to increase, much interest is focused on high-risk procedures in elderly patients, including major surgical operations. We investigated the results of endovascular coiling of unruptured intracranial aneurysms (UIA) in patients over 80 years of age.

Methods: We retrospectively analyzed 39 patients aged over 80 years who underwent coil embolization for UIA between April 2007 and April 2019 at our hospital.

Effectiveness of Cortical Atrophy Scale and Indirect Indices of Brain Atrophy to Predict Chronic Subdural Hematoma in Older Patients.

Objective: To determine whether baseline cerebral atrophy can predict the rate of future chronic subdural hematoma (CSDH) after head trauma and compare indirect markers of brain atrophy with volumetric analysis of computed tomography (CT).

Methods: Single institution case-control study involving 1,476 patients who visited our hospital after head trauma from January 2009 to December 2014. Forty-one patients with delayed CSDH were identified and age, gender matched 41 patients were selected as control group.

Pseudoaneurysm Formation after Repetitive Suction Thrombectomy Using a Penumbra Suction Catheter.

With the recent advent of suction catheters, the use of manual aspiration thrombectomy (MAT) for patients with acute ischemic stroke with large vessel occlusion has increased. Although contrast leakage and subarachnoid hemorrhage have been reported during MAT procedures, pseudoaneurysm formation due to vessel injury by suction catheters has not been. We discuss the case of a 60-year-old woman who presented to our emergency room with dysarthria and left-sided weakness.
