Paradoxical Brain Embolism Caused by Isolated Pulmonary Arteriovenous Fistula Successfully Treated with Recombinant Tissue Plasminogen Activator
Pulmonary arteriovenous fistula (PAVF), a vessel malformation connecting the pulmonary circulation to the systemic circulation while bypassing the pulmonary capillaries, can cause paradoxical cerebral infarction. It is often associated with hereditary hemorrhagic telangiectasia (HHT), a genetic disease characterized by multiple dermal, mucosal, and visceral telangiectasia causing recurrent bleeding. Paradoxical cerebral embolism caused by PAVF without HHT is rare. Here, we report a patient with isolated PAVF who experienced an ischemic stroke caused by a paradoxical embolism from deep venous thrombosis; the patient was suc...

Insulin-Like Growth Factor 2 (IGF-2) Regulates Neuronal Density and IGF-2 Distribution Following Hippocampal Intracerebral Hemorrhage
Memory is the most critical cognitive function in humans. Hippocampus infarcts and artery lesions in stroke and trauma cause levels of memory loss, and it is an apparent cause of disability in the communities.1,2 Intracerebral Hemorrhage (ICH) caused by bleeding in the brain parenchyma and penetration of the hematoma into the hippocampus leads to severe memory damage.3,4 Many arteries supply the hippocampus, most of which branch off of the posterior cerebral artery, the anterior temporal, and the anterior choroidal arteries.

Risk of Stroke vs. Intracerebral Hemorrhage in Patients with Non-Valvular Atrial Fibrillation Undergoing Percutaneous Coronary Intervention: A Systematic Review and Meta-Analysis of Randomized Controlled Trials Comparing Dual vs. Triple Antithrombotic Therapy
About 15% of patients with non-valvular atrial fibrillation might require percutaneous coronary interventions (PCIs) with stent placement to treat obstructive coronary artery disease. Dual antiplatelet therapy (DAPT) with acetylsalicylic acid (aspirin) and P2Y12 antagonist is recommended after PCI. Patients requiring DAPT also require treatment with oral anticoagulation for atrial fibrillation. We conducted a meta-analysis to identify the antithrombotic regimen associated with the lowest rate of bleeding and thromboembolic events in non-valvular atrial fibrillation after PCI.

An Enriched Environment Leads to Increased Synaptic Plasticity-Associated miRNA Levels after Experimental Subarachnoid Hemorrhage
Subarachnoid hemorrhage is a type of stroke caused by usually bleeding in the subarachnoid space with high morbidity and mortality.1,2 The cause is usually arterial aneurysm rupture and arterial hypertension. SAH also affects cognitive functions. Half of the patients may return to their daily lives in a year after SAH, but most of these patients often have problems in memory, executive functions, and speech functions in the future.3 Although long-term neurological disorders are thought to be caused by late-term cerebral ischemia due to vasospasm triggered by extravascular blood contact with the arteries, the molecular basi...

Pharmacological Difference Between Platelet Aggregations in Cardioembolic Stroke Patients with Direct Oral Anticoagulants: A Pilot Study
Major hemorrhagic complication incidence in patients with arterial fibrillation (AF), and treated with direct oral anticoagulants (DOACs), is lower than in vitamin K antagonist-treated patients.1 –5 Additionally, among DOACs, the direct oral thrombin inhibitor (dabigatran) and direct oral factor Xa (FXa) inhibitors (apixaban and rivaroxaban) seem to affect the coagulation system differently, which could provide distinct clinical outcomes.6,7 The results from the US6 and Denmark8 cohort stu dies suggest there is a minute, but notable difference in major bleeding complication incidence between dabigatran and FXa inhibitors.

Intraoperative imaging reveals spot sign with surgical correlate during early endoscopic ICH evacuation
Intracerebral hemorrhage (ICH) is the most devastating form of stroke. Intraoperative imaging and management of intracavity bleeding during early endoscopic ICH evacuation may mitigate rebleeding, hematoma expansion, and neurological worsening. Here we document a case of intraoperative spot sign, detected in the angio suite using cone beam CT with contrast protocol, in a patient with spontaneous supratentorial ICH undergoing evacuation 13 hours after last known well. The spot sign was detected after endoscopic evaluation of the evacuated hematoma cavity demonstrated sufficient hemostasis, but before completion of the case ...

Tranexamic Acid for Spontaneous Intracerebral Hemorrhage: A Randomized Controlled Pilot Trial (ISRCTN50867461)
Background: Spontaneous intracerebral hemorrhage (ICH) can be devastating, particularly if hematoma expansion (HE) occurs. Tranexamic acid (TA), an antifibrinolytic drug, significantly reduced mortality in bleeding patients after trauma in the large CRASH-2 trial. The CRASH-2 ICH substudy found that TA nonsignificantly reduced mortality and dependency in traumatic ICH. The aim of this study was to assess the feasibility of performing a randomized controlled trial of tranexamic acid in spontaneous ICH, ahead of a definitive study.Methods: We performed a single-center, prospective, randomized (2:1), double-blind, placebo-co...

Spatial Relationship between Cerebral Microbleeds, Moyamoya Vessels, and Hematoma in Moyamoya Disease
Conclusions: Spatial relationship was demonstrated between the moyamoya vessels and perivascular hemosiderin deposition particularly around the subependymal–leptomeningeal anastomosis, suggesting the mechanism for the development of cMBs in MMD. Present study further supports previous findings that cMBs potentially serve as a marker for the bleeding-prone microangiopathy in MMD. The significance of the present study lies in selecting optimal surgical candidate for preventing future hemorrhage by the presence of the cMBs, whereas current surgical indication relying on the degree of ischemia frequently fails to detect pati...

Subdural and Intracerebral Hemorrhage Caused by Spontaneous Bleeding in the Middle Meningeal Artery after Coil Embolization of a Cerebral Aneurysm
Nontraumatic acute subdural hemorrhage (SDH) with intracerebral hemorrhage (ICH) is rare and is usually caused by severe bleeding from aneurysms or arteriovenous fistulas. We encountered a very rare case of spontaneous bleeding from the middle meningeal artery (MMA), which caused hemorrhage in the temporal lobe and subdural space 2 weeks after coil embolization of an ipsilateral, unruptured internal cerebral artery aneurysm in the cavernous portion. At onset, the distribution of hematoma on a computed tomography scan led us to believe that the treated intracavernous aneurysm could bleed into the intradural space. Emergenc...

Cerebral Amyloid Angiopathy Causing Large Contralateral Hemorrhage During Surgery for Lobar Hemorrhage: A Case Report
We report a rare case of cerebral amyloid angiopathy (CAA) causing large contralateral hemorrhage during surgery for lobar hemorrhage. A 62-year-old woman presented with lobar hemorrhage in the left frontal and parietal lobes recurring over the previous 1 month. Because we could not detect the origin of the lobar hemorrhage, we performed a biopsy around the lobar hemorrhage site with the removal of a hematoma. During the surgery, we identified acute brain swelling without bleeding from the operative field.
