Intracranial bleeding

A 50-year-old male patient with a history of transcranial surgery and subsequent radiotherapy for a pituitary adenoma presented with repetitive pulsatile nasal bleeding. A right cavernous segment pseudoaneurysm was discovered on the angiogram, and the patient failed the balloon occlusion test. A Papyrus (Biotronik, Berlin, Germany) stent graft, which is approved for coronary interventions, was successfully deployed over a coaxial guiding system during the emergent treatment of the false aneurysm. The patient tolerated the procedure well and nasal bleeding did not recur after the procedure...

IMPORTANCE: Comparisons are limited for immediate-intensive and delayed-intensive statin for secondary stroke prevention and neuroprotection in patients with acute mild ischemic stroke or transient ischemic attack (TIA) from atherosclerosis. OBJECTIVE: To estimate whether immediate-intensive statin therapy is safe and can lower the risk of recurrent stroke compared with delayed-intensive statin in patients with acute mild ischemic stroke or high-risk TIA from atherosclerosis...

IMPORTANCE: Whether infarct size modifies the treatment effect of early vs late direct oral anticoagulant (DOAC) initiation in people with ischemic stroke and atrial fibrillation is unknown. OBJECTIVE: To assess whether infarct size modifies the safety and efficacy of early vs late DOAC initiation. DESIGN, SETTING, AND PARTICIPANTS: Post hoc analysis of participants from the multinational (>100 sites in 15 countries) randomized clinical Early Versus Later Anticoagulation for Stroke With Atrial Fibrillation (ELAN) trial who had (1) acute ischemic stroke, (2) atrial fibrillation, and (3) brain imaging available before randomization...

BACKGROUND: Cerebral microbleeds (CMBs) are an important risk factor for stroke recurrence and prognosis. However, there is no consensus on the safety of antiplatelet therapy in patients with ischemic stroke and CMBs. OBJECTIVE: This study aimed to observe the effects of dual antiplatelet therapy with aspirin and clopidogrel on bleeding conversion in patients with different degrees of CMBs. MATERIALS AND METHODS: An observational retrospective study was conducted on 160 patients with acute mild ischemic stroke admitted to the Stroke Center, Affiliated Hospital of Beihua University between March 2021 and December 2022...

BACKGROUND: Alteplase (tPA) is the initial treatment for acute ischemic stroke. Current tPA guidelines exclude patients who took direct oral anticoagulants (DOAC) within the prior 48 hours. In this propensity-matched retrospective study we compared acute ischemic stroke patients treated with tPA who had received DOACs within 48 hours of thrombolysis to those not previously treated with DOACs, regarding three outcomes: mortality; intracranial hemorrhage (ICH); and need for acute blood transfusions (as a marker of significant blood loss)...

BACKGROUND: Birth injury or birth trauma refers to physical damage or trauma that occurs to a newborn during the birthing process. To ensure continuous care and improve neonatal outcomes, it is crucial to know the incidence, types, relation to the mode of delivery, and their management. METHODOLOGY: This is a retrospective cohort study conducted at Aga Khan University Hospital, Pakistan from January 2018 to December 2022. Neonates aged from birth to 28 days of life identified to sustain any form of mechanical birth injuries were included...

When stroke occurs in pediatric age, it might be mistakenly interpreted as non-accidental head injury (NAHI). In these situations, a multidisciplinary approach is fundamental, including a thorough personal and familial history, along with accurate physical examination and additional investigations. Especially when the clinical picture is uncertain, it is important to remember that certain genetic conditions can cause bleeding inside the brain, which may resemble NAHI. Pediatric strokes occurring around the time of birth can also be an initial sign of undiagnosed genetic disorders...

Cancer-associated stroke is an evolving subgroup of embolic strokes of undetermined source. A man in his mid-20s with progressive follicular variant acinic cell carcinoma of the parotid was admitted because of new onset left-sided weakness. Neuroimaging confirmed a right middle cerebral artery infarction. After extensive diagnostics, stroke aetiology was deemed from cancer-induced hypercoagulability. Questions which arose regarding his management included (1) What was the best antithrombotic for secondary stroke prevention? (2) What was his risk for intracranial or tumorous bleeding once antithrombotics had been started? (3) How many days post-stroke could the antithrombotic be initiated? and (4) When could he be cleared for palliative chemotherapy and whole brain irradiation? The approach to address the abovementioned questions in the management of a rare cancer complicated by stroke is presented...

BACKGROUND: Long-term anticoagulation (AC) therapy reduces the risk of stroke in patients with Atrial Fibrillation (AF). However, data on the impact of AC on in-hospital stroke outcomes is lacking. METHODS: The National Inpatient Sample was used to identify adult inpatients with AF and a primary diagnosis of ischemic stroke between 2016 and 2020. Data was stratified between AC users and nonusers. A multivariate regression model was used to describe the in-hospital outcomes, adjusting for significant comorbidities...

BACKGROUND: Middle fossa arachnoid cysts (MFACs) are rare, congenital lesions that may rupture and cause symptoms of elevated intracranial pressure. We sought to describe the presence of and factors associated with optic nerve edema in MFACs, focusing on the utility of ophthalmologic evaluations for guiding cyst management. METHODS: We reviewed clinical and radiographic information for all patients with MFACs with ophthalmologic evaluations at our institution. Headache, cranial nerve palsy, emesis, altered mental status, fatigue, and seizures were considered MFAC-related symptoms...

Classical trigeminal neuralgia (TN), caused by vascular compression of the nerve root, is a severe cause of pain with a considerable impact on a patient's quality of life. While microvascular decompression (MVD) has lower recurrence rates when compared with partial sensory rhizotomy (PSR) alone, refractoriness can still be as high as 47%. We aimed to assess the efficacy and safety profile of MVD + PSR when compared to standalone MVD for TN. We searched Medline, Embase, and Web of Science following PRISMA guidelines...

BACKGROUND: Venous thromboembolism (VTE) has a serious impact on the prognosis of patients with spontaneous intracranial hemorrhage (sICH). However, the use of prophylactic heparin remains controversial. OBJECTIVES: This study investigated the safety and timing of prophylactic heparin for VTE in patients with sICH. DESIGN: This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines...

Secondary prevention of patients with chronic coronary syndrome is based on the long-term use of a single anti-aggregating drug which is traditionally represented by acetylsalicylic acid (ASA) in light of the results of studies and meta-analyses which have demonstrated a clear anti-ischaemic efficacy against of an acceptable increase in the risk of bleeding, especially intracranial and gastrointestinal bleeding. The availability of drugs such as clopidogrel, which inhibits platelet activity through the P2Y12 receptor pathway, has called into question this paradigm, also in consideration of the fact that the scientific evidence that supports the use of ASA in secondary prevention is based on dated studies with some limitations...

Acute subdural hemorrhages are a common emergency presentation often associated with trauma. However, in the absence of significant trauma, it is important to consider alternative causes. In this case, a 58-year-old woman with trivial trauma after a sudden collapse had bilateral subdural hemorrhages on CT. CT-angiogram revealed anterior communicating artery aneurysm, which had ruptured. This case explores intracerebral aneurysms as a rare cause of subdural hemorrhage that is important to consider in the absence of significant trauma...

BACKGROUND: This review aims to evaluate the safety and efficacy of apixaban vs. vitamin K antagonists (VKAs) in patients on dialysis. METHODS: All types of studies published on PubMed, Embase, CENTRAL, and Web of Science up to 10 September 2023 and comparing outcomes of apixaban vs. VKA in dialysis patients were eligible. RESULTS: Two randomized controlled trials (RCTs) and six retrospective studies were included. Apixaban treatment was associated with significantly lower risk of major bleeding (RR: 0...

INTRODUCTION: Superficial siderosis (SS) of the central nervous system (CNS) is a rare disease characterized by deposition of hemosiderin along the leptomeninges, due to chronic or recurrent bleeding into the subarachnoid space. The association of unruptured intracranial aneurysm (IA) and cortical SS is a quite rare occurrence. METHODS: Systematic literature review to assess possible commonalities and/or differences of previous reported cases was undertaken. CASE PRESENTATION: We report a case of a 40-year-old woman with a history of generalized seizures over the past year...

Background: Impella devices are used for mechanical circulatory support in patients with cardiogenic shock or those undergoing high-risk percutaneous coronary intervention (PCI). Anticoagulation protocols in this population are not well established and are complicated by concomitant use of purge solutions containing unfractionated heparin (UFH) and intravenous UFH continuous infusion (CI) for systemic anticoagulation. Objectives: To evaluate thrombotic and bleeding complications when using a novel UFH protocol with a reduced initial UFH CI dose of 6 units/kg/hour targeting an anti-Xa goal of 0...

This article addresses the management of venous thromboembolism in patients with malignant brain tumours, including both primary and secondary (metastatic) tumours. The available data on patients on venous thromboembolism recurrence and bleeding risks in patients with brain tumours is limited, since these patients have been excluded from most randomised, interventional, head-to-head, clinical trials comparing low molecular weight heparins to vitamin K antagonists or to direct oral factor Xa inhibitors. More information is available from retrospective observational studies, which however were generally small, and carried a high risk of confounding...

Neuromodulatory interventions are relatively novel and approaches to studying harms and tolerability have varied. Using a checklist based on guidelines from Good Clinical Practice and the Harms Extension of the CONSORT (Consolidated Standards of Reporting Trials) Statement, we identified how adverse events are measured, assessed, and reported in studies evaluating neuromodulation for the treatment of mental and neurodevelopmental disorders among children and adolescents. A systematic literature review identified 56 experimental and quasi-experimental studies evaluating transcranial magnetic stimulation (TMS), transcranial alternating (tACS) or direct (tDCS) current stimulation, transcranial pulse stimulation (TPS), and vagus or trigeminal nerve stimulation (VNS or TNS)...

Delayed cerebral ischemia (DCI) is a serious, life-threatening, complication affecting patients who have survived the initial bleeding from a ruptured intracranial aneurysm. Due to the challenging diagnosis, potential DCI prognostic markers should be of value in clinical practice. According to recent reports isoprostanes and red blood cell distribution (RDW) showed to be promising in this respect. We conducted a prospective study of 27 aSAH patients and control group (n = 8). All patients from the study group were treated within the first day of the initial bleeding...
