Cerebral Bleed

BACKGROUND: Enterprise stent was approved for the treatment of wide-necked intracranial aneurysms. However, it has been widely used in the endovascular treatment of intracranial artery stenosis, which is still controversial. The purpose of this study was to evaluate the safety and efficiency of the Enterprise stent in the endovascular treatment of intracranial artery stenosis disease. METHODS: We conducted a retrospective case series of 107 patients with intracranial artery stenosis who received Enterprise stent implantation at Nanjing Drum Tower Hospital from January 2020 to December 2022...

INTRODUCTION: Patients of acute coronary syndrome (ACS) at a high-bleeding risk (HBR) often require dual antiplatelet therapy (DAPT) to reduce the risk of recurrent cardiovascular events. Clopidogrel and ticagrelor are the most commonly used antiplatelet agents in DAPT regimens. However, the safety profiles of these drugs in ACS patients at HBR remain a subject of ongoing debate. AIM: To investigate any difference between the safety of clopidogrel and ticagrelor used as a part of DAPT regimen in ACS patients at HBR...

Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a relatively rare and treatable subtype of CAA. We have herein reported a case of CAA-ri with repeated recurrent lobar haemorrhages within a short time as the main manifestations and effectively treated with immunosuppressive therapy. Our case expanded the clinical spectrum of CAA-ri and indicated that leptomeningeal inflammation might be a trigger and bleeding source for recurrent haemorrhage in CAA.

BACKGROUND: Radiation treatment for diseases of the brain can result in hemorrhagic adverse radiation effects. The underlying pathologic substrate of brain bleeding after irradiation has not been elucidated, nor potential associations with induced somatic mutations. METHODS: We retrospectively reviewed our department's pathology database over 5 years and identified 5 biopsy specimens (4 patients) for hemorrhagic lesions after brain irradiation. Tissues with active malignancy were excluded...

OBJECTIVE: The relationships between immediate bleeding severity, postoperative complications, and long-term functional outcomes in patients with aneurysmal subarachnoid hemorrhage (aSAH) remain uncertain. Here, the authors apply their recently developed automated deep learning technique to quantify total bleeding volume (TBV) in patients with aSAH and investigate associations between quantitative TBV and secondary complications, adverse long-term functional outcomes, and death. METHODS: Electronic health record data were extracted for adult patients admitted to a single institution within 72 hours of aSAH onset between 2018 and 2021...

Introduction Reversible cerebral vasoconstriction syndrome (RCVS) is most commonly characterized by focal or diffuse severe thunderclap headache with or without focal neurological deficits and associated transient focal vasoconstriction of the intracerebral arteries lasting up to three months. We present six patients diagnosed as RCVS, with three patients presenting with focal neurological deficits without headache and the remaining three with severe headache alone. Neuroimaging revealed focal subarachnoid bleed with or without segmental intracerebral vasospasm, which resolved over three months...

AIMS: Alteplase is a cornerstone thrombolytic agent in clinical practice, but presents a potential bleeding risk. Stroke patients need pre-screening to exclude hemorrhagic stroke before using Alteplase. In this study, we develop a new thrombolytic agent citPA5, characterized by an enhanced safety profile and minimal bleeding tendency. METHODS AND RESULTS: A clot lysis agent, named citPA5, is developed based on rtPA with point mutations to completely suppress its proteolytic activity in the absence of fibrin...

BACKGROUND: Cerebral cavernous malformation (CCM) is a disease associated with elevated risk of focal neurological deficits, seizures, and hemorrhagic stroke. The disease has an inflammation profile and improved knowledge of CCM pathology mechanisms and exploration of candidate biomarkers will enable new non-invasive treatments. METHODS: We analyzed protein expression signature in human CCM tissue samples by using a highly specific and sensitive multiplexing technique, proximity extension assay...

Vertigo is a complication of craniomaxillofacial contour plastic surgery characterized by dizziness from hypovolemia in the cerebral hemispheres and brainstem. The authors analyzed the current status and influencing factors of postoperative vertigo in patients who undergo craniomaxillofacial contouring and discussed improvements in nursing strategies. The authors investigated 418 patients admitted to the authors' hospital who underwent craniomaxillofacial contouring between November 2020 and October 2023 and divided them into asymptomatic and symptomatic groups based on syncopal precursors or vertigo...

OBJECTIVES: To investigate the safety of early antiplatelet therapy in non-cardioembolic mild stroke patients with thrombocytopenia. METHODS: Data of acute ischemic stroke patients with baseline National Institutes of Health Stroke scale (NIHSS) score ≤3 and a platelet count <100×109 /L were obtained from a multicenter register. Those who required anticoagulation or had other contraindications to antiplatelet therapy were excluded. Short-term safety outcomes were in-hospital bleeding events, while the long-term safety outcome was 1-year all-cause death...

BACKGROUND: Local vasogenic edema induced after direct revascularization in moyamoya disease (MMD) is associated with blood-brain barrier dysfunction, potentially leading to postoperative cerebral hyperperfusion (CHP) or delayed intracerebral hemorrhage. This phenomenon allows the leakage of fluids, proteins, and other substances from the blood vessels into the extracellular compartment. Typically, such edema is observed postoperatively rather than intraoperatively. OBSERVATIONS: A 48-year-old female with ischemic-onset MMD underwent revascularization on her left hemisphere with Suzuki's angiographic stage III...

BACKGROUND: No uniform consensus has been achieved regarding the ambulation protocol after transfemoral cerebral angiography (TFA). Until now, in most hospitals patients are prescribed 8-12 h strict immobilization along with bed rest in the supine position after TFA in China, which causes great discomfort to patients. OBJECTIVE: To evaluate the effect of an evidence-based early ambulation protocol on the prevention of vascular complications and general discomfort in patients following transfemoral cerebral angiography (TFA)...

Percutaneous techniques for femoral arterial access are increasingly being performed due to advances in endovascular cerebral procedures, as they provide a less morbid and minimally invasive approach than open procedures. Common complications associated with this peripheral puncture include hematoma, bleeding, pseudoaneurysm, arteriovenous fistula, retroperitoneal bleeding, inadvertent venous puncture, dissection, etc. The retrograde femoral access is currently the most frequently used arterial access as it is technically straightforward, allows for the use of larger size sheaths and catheters, allows repeated attempts, etc...

Basal ganglia germinomas (BGGs) are rare lesions. Because of the atypical features of early-stage clinical symptoms and imaging characteristics, BGGs are easily misdiagnosed with non-tumorous conditions. This article presented cases of 2 young male patients who came to the hospital due to right arm weakness. Brain Magnetic Resonance Imaging (MRI) images in the first case revealed a lobulated mixed component mass on the left basal ganglia. The solid part showed restricted diffusion on diffusion-weighted imaging, heterogeneous strong enhancement, and no signal of calcification or bleeding...

BACKGROUND: Sporadic cerebral small-vessel disease (CSVD), i.e., hypertensive arteriopathy (HA) and cerebral amyloid angiopathy (CAA), is the main cause of spontaneous intracerebral hemorrhage (ICH). Nevertheless, a substantial portion of ICH cases arises from non-CSVD etiologies, such as trauma, vascular malformations, and brain tumors. While studies compared HA- and CAA-related ICH, non-CSVD etiologies were excluded from these comparisons and are consequently underexamined with regard to additional factors contributing to increased bleeding risk beyond their main pathology...

BACKGROUND: Approximately 90% of intracardial thrombi originate from the left atrial appendage in non-valvular atrial fibrillation patients. Even with anticoagulant therapy, left atrial appendage thrombus (LAAT) still occurs in 8% of patients. While left atrial appendage closure (LAAC) could be a promising alternative, the current consensus considers LAAT a contraindication to LAAC. However, the feasibility and safety of LAAC in patients with LAAT have yet to be determined. METHODS: This systematic review synthesizes published data to explore the feasibility and safety of LAAC for patients with LAAT...

OBJECTIVE: This study focuses on exploring the efficacy observation, complications, and nursing aspects of using enteral nutrition suspension in patients with acute ischemic stroke. METHODS: This study retrospectively analyzed clinical data from 188 patients with acute ischemic stroke treated in the Neurology Department of our hospital from October 2022 to September 2023. Patients who received routine treatment and nursing interventions were included in the control group (96 cases), while patients who received additional treatment with enteral nutrition suspension on top of the control group were included in the treatment group (92 cases)...

BACKGROUND: The very elderly (≥80 years) are at high risk of nonvalvular atrial fibrillation and thromboembolism. Given its recent approval, the comparative effectiveness and safety of edoxaban in this population, relative to the commonly used apixaban, remain unknown. METHODS: Using the United Kingdom Clinical Practice Research Datalink, we identified a cohort of patients aged ≥80 with incident nonvalvular atrial fibrillation and newly treated with edoxaban or apixaban between 2015 and 2021...

For patients with moyamoya disease, antiplatelet agents are often used during the perioperative periods of revascularization surgeries to prevent ischemic events. However, antiplatelet therapy is associated with the risk of hemorrhagic complications. Further, the influence of antiplatelet therapy on perioperative ischemic or hemorrhagic complications has not been investigated. This study aimed to determine the impact of antiplatelet agents on adult moyamoya disease patients with ischemic onset during the perioperative period...
