Advantages of 3D High-Resolution Vessel Wall Imaging in a Patient With Blood Blister-Like Aneurysm: A Case Report and Literature Review.

Blood blister-like aneurysms (BBAs) are rare and challenging intracranial aneurysms. They pose significant diagnostic and surgical risks due to their delicate walls. Accounting for a small percentage of intracranial aneurysms, BBAs are pathologically pseudoaneurysms, often resulting from arterial dissection, with a high tendency to rupture.

A cavernous sinus dural arteriovenous fistula treated by direct puncture of the superior ophthalmic vein with craniotomy: illustrative case.

Background: The authors report a case of symptomatic cavernous sinus (CS) dural arteriovenous fistula (dAVF) that was successfully treated using direct puncture of the superior ophthalmic vein (SOV) with craniotomy. CS dAVF is commonly treated using transvenous embolization (TVE), with the most common access route via the inferior petrosal sinus (IPS). However, this route is sometimes unavailable because of an occluded, hypoplastic, aplastic, or tortuous IPS.

Percutaneous transluminal angioplasty for persistent primitive hypoglossal artery stenosis: illustrative case.

Background: We report a case of symptomatic, progressive stenosis of a persistent primitive hypoglossal artery (PPHA), which was successfully treated with percutaneous transluminal angioplasty (PTA) of the origin of the PPHA. The PPHA is a type of carotid-basilar anastomosis with an incidence of 0.02% to 0.

Angiogenic and inflammatory responses in human induced microglia-like (iMG) cells from patients with Moyamoya disease.

Angiogenic factors associated with Moyamoya disease (MMD) are overexpressed in M2 polarized microglia in ischemic stroke, suggesting that microglia may be involved in the pathophysiology of MMD; however, existing approaches are not applicable to explore this hypothesis. Herein we applied blood induced microglial-like (iMG) cells. We recruited 25 adult patients with MMD and 24 healthy volunteers.

Protein Nanoparticles Modified with PDGF-B as a Novel Therapy After Acute Cerebral Infarction.

Treatment options for cerebral infarction beyond the time window of reperfusion therapy are limited, and novel approaches are needed. PDGF-B is considered neuroprotective; however, it is difficult to administer at effective concentrations to infarct areas. Nanoparticles (NPs) are small and stable; therefore, we modified PDGF-B to the surface of naturally occurring heat shock protein NPs (HSPNPs) to examine its therapeutic effect in cerebral infarction.

A Novel Hyperspectral Imaging System for Intraoperative Prediction of Cerebral Hyperperfusion Syndrome after Superficial Temporal Artery-Middle Cerebral Artery Anastomosis in Patients with Moyamoya Disease.

Background: Postoperative cerebral hyperperfusion syndrome (CHS) may occur after superficial temporal artery (STA)-middle cerebral artery (MCA) bypass for moyamoya disease (MMD). Predicting postoperative CHS is challenging; however, we previously reported the feasibility of using a hyperspectral camera (HSC) for monitoring intraoperative changes in brain surface hemodynamics during STA-MCA bypass.

Objective: To investigate the utility of HSC to predict postoperative CHS during STA-MCA bypass for patients with MMD.

Coiling for a saccular aneurysm on the caudal channel in double origin of the posterior inferior cerebellar artery.

Background: Double origin of the posterior inferior cerebellar artery (DOPICA) is a rare cranial imaging finding with an incidence of 0.36-6% reported in various retrospective studies. Aneurysms on a DOPICA are even rarer.

Usefulness of Oral Xa Inhibitor for Management of Ischemic Stroke Associated with Thrombosis in the Pulmonary Vein Stump after Lung Resection.

Objectives: Brain infarction is a critical complication after lung resection using video-assisted thoracoscopic surgery. Recent reports have described its association with thrombosis in the pulmonary vein (PV) stump. However, the optimal management of this complication remains controversial.

Epstein-Barr virus-positive diffuse large B-cell primary central nervous system lymphoma associated with organized chronic subdural hematoma: a case report and review of the literature.

We here report on a rare case of Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) detected in both brain parenchyma and in an organized chronic subdural hematoma (OCSH). A 96-year-old man diagnosed with asymptomatic OCSH in the left frontal convexity was referred to our hospital because of a de novo mass lesion just beneath the OCSH on contrast-enhanced magnetic resonance imaging. The size of the OCSH remained stable.
