OBJECTIVE The evaluation of the venous neurovasculature, especially the dural venous sinuses, is most often performed using MR or CT venography. For further assessment, diagnostic cerebral angiography may be performed. Three-dimensional rotational angiography (3D-RA) can be applied to the venous system, producing 3D rotational venography (3D-RV) and cross-sectional reconstructions, which function as an adjunct to traditional 2D digital subtraction angiography. METHODS After querying the database of Baylor St...

Bilateral thalamic dysfunction secondary to venous congestion may result from either venous sinus thrombosis or high flow arteriovenous malformations or a combination of both. We present a case of bilateral thalamic edema resulting from concomitant choroid plexus arteriovenous malformation (AVM) and straight sinus thrombosis and describe our treatment approach. The patient presented with several weeks of progressive confusion and memory deficits. Magnetic resonance imaging and venography (MRI/ MRV) showed bilateral thalamic T2 hyperintensities and straight sinus thrombosis...

RATIONALE: Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSAH) is characterized by a pattern of extravasated blood restricted to the perimesencephalic cisterns, normal angiographic findings, and an excellent prognosis with an uneventful course and low risks of complication. The precise etiology of bleeding in patients with PNSAH has not yet been established. The most common hypothesis is that PNSAH is venous in origin. Intracranial venous hypertension has been considered as the pivotal factor in the pathogenesis of PNSAH...

BACKGROUND: Intensive care for comatose survivors of cardiac arrest includes targeted temperature management (TTM) to attenuate cerebral reperfusion injury. A recent multi-center clinical trial did not show any difference in mortality or neurological outcome between TTM targeting 33°C or 36°C after out-of-hospital-cardiac-arrest (OHCA). In our institution, the TTM target was changed accordingly from 34 to 36°C. The aim of this retrospective study was to analyze if this change had affected patient outcome...

We report a case of an 8-year-old girl with posterior fossa abnormalities, haemangioma, arterial lesions, cardiac abnormalities or coarctation of the aorta and eye abnormalities syndrome with right carotid aplasia and complete basilar occlusion. The patient initially presented at 2.5 weeks of age with a growing right facial haemangioma involving segments 1, 3 and 4. Initial MRI at 2.5 weeks of age revealed an extraconal right orbital haemangioma without posterior fossa abnormalities and MR angiography (MRA) 3 weeks later showed right internal carotid aplasia...

PURPOSE: Delayed cerebral ischemia (DCI) still remains a major complication after subarachnoid hemorrhage (SAH). The aim of our study was to evaluate whether flow analysis of admission digital subtraction angiography (DSA) using parametric color coding (PCC), a postprocessing algorithm, allows ultra-early identification of SAH patients at risk for developing subsequent symptomatic vasospasm. METHODS: In this study 52 patients who suffered SAH from aneurysm rupture, were retrospectively enrolled...

Compressed sensing (CS) MRI has just been introduced to research areas as an innovative approach to accelerate MRI. CS is expected to achieve higher k-space undersampling by exploiting the underlying sparsity in an appropriate transform domain. MR angiography (MRA) provides high spatial resolution information on arteries; however, a relatively long acquisition time is necessary to cover a wide volume. Reduction of acquisition time by CS for time-of-flight (TOF) MR angiography (Sparse-TOF) is beneficial in clinical examinations; therefore, the clinical validity of Sparse-TOF needs to be investigated...

We report the case of an 18-year-old woman with personality disorders who was hospitalized a few hours after suicidal ingestion of acetaminophen, quetiapine, acetylsalicylic acid, and ethanol. Twelve hours after admission, severe liver damage was evident, but the patient was stable and awaiting hepatic transplantation. Electrolytes were successfully controlled. The condition of the liver stabilized. Cardiac biomarkers then deteriorated unexpectedly. Localized ST-segment elevations were noted on electrocardiogram, but angiography ruled out myocardial infarction...

Pilocytic astrocytomas are found predominantly in the pediatric population and are extremely rare in elderly patients. We describe a case of pilocytic astrocytoma in an elderly patient who presented with the symptoms of an enlarged tumoral cyst. A 70-year-old woman was found to have an asymptomatic small solid tumor with a cystic component in the right frontal lobe at "Ningen Dock(medical checkup)of the Brain". She was hospitalized and underwent further examinations including cerebral angiography. At that time, she was opposed to undergoing an operation for tumor removal owing to lack of symptoms...

We report the case of a patient who has progressed well over 5 years following single-stage aneurysm clipping and superficial temporal artery-middle cerebral artery(STA-MCA)double anastomoses in the acute phase, for a ruptured distal anterior choroidal artery(AChA)aneurysm accompanied by a twig-like MCA. The patient was a 49-year-old female who developed a sudden severe headache and disturbance of consciousness due to subarachnoid hemorrhage and intraventricular hemorrhage(IVH). Cerebral angiography showed a right twig-like MCA associated with an abnormal vascular network and a ruptured aneurysm in the distal AChA...

INTRODUCTION: It is expected that anatomical variations in the circle of Willis have a direct effect on blood flow in the internal carotid artery. Rupture of the lenticulostriate artery of the middle cerebral artery 1st segment (M1) is the most common cause of putaminal intracerebral hemorrhage(ICH), and we hypothesized that this could be related to the anatomical variations of the circle of Willis and the predominance of the anterior cerebral artery 1st segment (A1). METHODS: We retrospectively reviewed the records of 544 patients who were treated for spontaneous ICH between 2013 and 2016 at Yeungnam University Hospital...

Vascular changes during spontaneous headache attacks have been studied over the last 30 years. The interest in cerebral vessels in headache research was initially due to the hypothesis of cerebral vessels as the pain source. Here, we review the knowledge gained by measuring the cerebral vasculature during spontaneous primary headache attacks with the use of single photon emission tomography (SPECT), positron emission tomography (PET), magnetic resonance imaging (MRA) and transcranial Doppler (TCD). Furthermore, the use of near-infrared spectroscopy in headache research is reviewed...

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired disease characterized by clonal hematopoietic stem cell disorder, with increased mortality and morbidity. Venous thrombosis is the most common cause of mortality in PNH. The relationship between PNH and cerebrovascular disease is unclear; few cases are reported in the literature, most of them related to cerebral venous thrombosis; In PNH the involvement of intracranial and extracranial arterial sites is very rare. We report a case of a 49-year-old woman who has a medical history of diabetes mellitus, hypertension, and PNH and presented multiple lacunar strokes in a routine consultation with a hematologist...

BACKGROUND: Cranioplasty is a well-established surgical operation that is used worldwide for skull defect patients following decompressive craniectomy (DC). However, especially in some cases, fatal complications such as malignant cerebral swelling after uneventful cranioplasty should be attended to. CASE DESCRIPTION: We present a rare case of massive malignant ipsilateral cerebral swelling following uneventful titanium mesh cranioplasty due to rare ipsilateral intracranial vasculopathy confirmed by magnetic resonance angiography and magnetic resonance venography (MRA and MRV)...

- A diagnosis of cerebral vasculitis is frequently considered in patients with new or progressive neurological symptoms for which there is no other explanation.- A clinician considering a diagnosis of cerebral vasculitis should be well aware of alternative diagnoses, since these are generally more common.- Several consecutive examinations are required for diagnosing cerebral vasculitis, because there is no diagnostic procedure that is highly sensitive as well as highly specific.- The added value of the different procedures may depend on the type of blood vessels involved...

Statins have pleiotropic effects that are considered beneficial in preventing cerebral vasospasm and delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage (aSAH). Many studies using statins have been performed but failed to show remarkable effects. We hypothesized that a long-acting statin would be more effective, due to a longer half-life and stronger pleiotropic effects. Patients with aSAH were randomly assigned to a pitavastatin group (4 mg daily; n = 54) and a placebo group ( n = 54) after repair of a ruptured aneurysm...

BACKGROUND: The frontal bridging vein, which is the venous drainage route of the frontal cortex into the superior sagittal sinus (SSS), sometimes poses an obstacle in the anterior interhemispheric approach during surgery for anterior cerebral artery aneurysms. Although severe complications including venous infarction or edema due to damage to the bridging vein are well known, only a few reports have discussed how to avoid venous injury when we must sacrifice the bridging vein to obtain an appropriate surgical field...
