Background Cerebral edema is frequent in patients with acute ischemic stroke (AIS) who undergo reperfusion therapy and is associated with high mortality. The impact of collateral pial circulation (CPC) status on the development of edema has not yet been determined. Methods We studied consecutive patients with AIS and documented M1-middle cerebral artery (MCA) and/or distal internal carotid artery (ICA) occlusion who underwent reperfusion treatment. Edema was graded on the 24-hour non-contrast computed tomography (NCCT) scan...

The video demonstrates resection of a Grade II Spetzler-Martin unruptured, medium-sized arteriovenous malformation (AVM). A young woman presented with headaches and seizures. The right frontal lesion measured 4.5 cm in largest dimension and had superficial venous drainage. Partial Onyx embolization, primarily of the anterior cerebral feeding arteries, was performed. Bone removal for exposure allowed identification of indentation from the large superficial draining vein. The video demonstrates careful microsurgical dissection on the AVM/brain interface, with selective interruption of feeding arteries circumferentially...

Case: Circulatory support using veno-arterial extracorporeal membrane oxygenation for aortic disease is conventionally contraindicated. In this case, a 66-year-old man experienced cardiopulmonary arrest caused by acute aortic dissection. When exercising in the gym, he experienced chest discomfort, so the staff immediately called an ambulance. While in the ambulance, he experienced cardiopulmonary arrest. His initial electrocardiogram showed ventricular fibrillation. At the emergency department, we immediately performed extracorporeal cardiopulmonary resuscitation...

Iatrogenic and traumatic cerebral internal carotid artery injuries are uncommon but potentially lethal complications. Direct surgical repair of ICA injuries may be difficult in an acute setting. However, endovascular treatment with a flow-diverter embolization device is a feasible alternative technique that we experienced. In this clinical report, we describe demographic data, radiographic images, lesion characteristics, endovascular procedure notes, postprocedural hospital course, and follow-up digital subtraction angiography of 5 patients...

Paradoxical embolism due to isolated pulmonary arteriovenous malformation (AVM) is an uncommon cause of ischemic stroke, with the majority occurring in patients who have not yet been diagnosed with their malformation. We report a 32-year-old man who presented with an abrupt onset of right facial weakness and expressive aphasia. Brain magnetic resonance imaging revealed an acute infarct in the left middle cerebral artery territory and chronic infarcts in the bilateral cerebellar hemispheres. A cardioembolic mechanism was initially considered in the setting of perimyocarditis diagnosed a few months earlier...

BACKGROUND: Transient global amnesia is reported to be caused by cerebral venous congestion. Internal jugular venous flow reversal in particular with the Valsalva maneuver leads to cerebral venous congestion. In addition, Valsalva maneuver can also induce subarachnoid hemorrhage. Transient global amnesia and subarachnoid hemorrhage might have common a pathophysiology in cerebral venous congestion. CASE PRESENTATION: We report here the case of a 57-year-old woman who twice experienced convexal subarachnoid hemorrhage just after straining at stool following an episode of transient global amnesia...

OBJECTIVE The purpose of this study was to evaluate the detection rate and occurrence site according to patient sex and age of unruptured intracranial aneurysms detected through MRI and MR angiography (MRA). METHODS A total of 4070 healthy adults 22 years or older (mean age [± SD] 50.6 ± 11.0 years; 41.9% women) who underwent a brain examination known as "Brain Dock" in the central Tokyo area between April 2014 and March 2015 were checked for unruptured saccular aneurysm using 3-T MRI/MRA. The following types of cases were excluded: 1) protrusions with a maximum diameter < 2 mm at locations other than arterial bifurcations, 2) conical protrusions at arterial bifurcations with a diameter < 3 mm, and 3) cases of suspected aneurysms with unclear imaging of the involved artery...

Posterior cerebral artery (PCA) aneurysms can be technically challenging lesions due to the intricacy of perforating branches and the relationship to cranial nerves and the brainstem. Fusiform aneurysms of the perimesencephalic segment of the PCA are a rare finding which does not favor direct clip occlusion or reconstruction. In such cases, proximal parent vessel occlusion is an option for aneurysm treatment. Extracranial-intracranial (EC-IC) bypass can be used to revascularize beyond the lesion when considering proximal occlusion...

BACKGROUND: Cerebrovascular disease (CVD) is a risk factor of stroke and cerebral hypoperfusion is one of the underlying mechanisms. We hypothesized that coronary artery bypass grafting (CABG) can be performed at an acceptable risk for such patients without concomitant surgery for CVD. METHODS: Carotid echo was carried out for 538 consecutive patients undergoing isolated CABG between 2005 and 2016. Magnetic resonance image/angiography (MRI/A) for neck and brain was performed for 288 patients (stenosis≥50% in echo were basically included)...

Intracranial 'kissing' aneurysms are rare types of multiple aneurysms referring to two adjacent aneurysms arising from identical or different arteries with separate origins and partially adherent walls. The present study reported a 54-year-old female patient, who was identified with a 'kissing' aneurysm in the A3 segment of the bilateral anterior cerebral arteries, as demonstrated by head computed tomography and emergency cerebral digital subtraction angiography analysis. In total, 12 days following the clipping of the aneurysms, the patient was discharged with a Modified Rankin Scale=0 and recovered well with no neurological deficits...

BACKGROUND: Superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis is the standard treatment for Moyamoya disease (MMD). Cerebral hyperperfusion syndrome is a potential complication of this procedure and can cause local vasogenic edema and/or delayed intracerebral hemorrhage. Cerebral hypoperfusion is a contradictory postoperative pathophysiological condition implicated in MMD, but its association with symptomatic local vasogenic edema has not been reported. CASE REPORT: A 31-year-old woman with MMD underwent left STA-MCA anastomosis 3 months after a minor completed stroke in bilateral hemispheres...
