Angiographical Jaggy Sign of Remnant M2 Occlusion during Acute Mechanical Thrombectomy
In this study, we focused on the angiographical findings of remnant occlusion. Methods: Among 83 patients who underwent mechanical thrombectomy for the acute internal carotid artery or proximal middle cerebral artery (M1) occlusion, 25 patients (30%) intraoperatively exhibited the remnant M2 occlusion, in spite of the recanalization of the other M2.

Detection of Stenosis Progression in Intracranial Vertebral Artery Dissection Using Carotid Ultrasonography
Background: The purpose of this study was to assess whether carotid ultrasonography indices detect arterial stenosis progression in patients with vertebral artery (VA) dissection. Methods: This was a retrospective, single-center, observational study that enrolled patients with intracranial VA dissection who were admitted from January 2011 to June 2017. Magnetic resonance angiography (MRA) was done on admission and followed up at a median 20 days after onset (interquartile range [IQR] 9-58 days), and ultrasonography was performed at a median of 22 (interquartile range 7-56) days.

Intraoperative Aneurysm Rupture during Resection for Presumed Metastasis
A 54-year-old male with metastatic melanoma, including a presumed brain metastasis underwent elective surgery when there was sudden onset of extensive bleeding upon resection. An emergent cerebral angiogram revealed a fusiform left posterior cerebral artery aneurysm. Malignant melanoma commonly metastasizes to the brain and has shown to assume a wide variety of appearances with involvement of almost any intracranial structures. The unexpected intraoperative finding required immediate action and strategic rethinking.

Dural Sinus Thrombosis with Nonsymptomatic Persistent Falcine Sinus: A Case Report
A 24-year-old woman was admitted to our hospital after convulsive status epilepticus. A cerebral magnetic resonance venography revealed a persistent fetal falcine sinus. Additionally, the posterior third of the superior sagittal sinus was hypoplastic and the abnormal deep venous drainage was accompanied. These abnormalities had already been detected by magnetic resonance imaging several years ago. In the present scan, we discovered a sinus thrombosis in the hypoplastic superior sagittal sinus. In the cerebral angiography, we observed delayed venous return in the left parieto-occipital lobe and hypothesized that cerebral ve...

Carotid-Cavernous Sinus Fistula caused by Persistent Primitive Trigeminal Artery Aneurysm rupture: A case report
Carotid-Cavernous sinus fistula (CCF) caused by a ruptured aneurysm of persistent primitive trigeminal artery (PPTA) is exceptionally rare. Herein, we reported the case of a 64-year-old female who presented with headache, pulsatile tinnitus, and diplopia. Angiography showed a PPTA and CCF. Three-dimensional digital subtraction angiograms revealed a direct shunt between the PPTA aneurysm and the left cavernous sinus. The trigeminal carotid fistula was successfully treated with detachable coils and Onyx, and the PPTA was preserved.

Clinical and Radiological Difficulties to Detect Isolated MCA Dissection before Intravenous tPA Therapy
A 64-year-old woman was admitted to our hospital 48 minutes after sudden onset of dysphasia and right hemiplegia. Head computed tomography revealed small infarcts in the left putamen and 4-dimensional computed tomography angiography depicted high-degree stenosis in the left middle cerebral artery and delayed filling of the contrast media in the left middle cerebral artery territory. The patient underwent intravenous tissue plasminogen activator treatment. On day 5 of hospitalization, the patient underwent conventional cerebral angiography, revealing internal carotid artery to middle cerebral artery dissection.

Carotid Webs in Cryptogenic Ischemic Strokes: A Matched Case-Control Study
Background: Young individuals with symptomatic carotid webs may be predisposed to ischemic strokes. However, evidence remains scarce. This investigation reports the frequency of carotid webs among patients with cryptogenic strokes compared to a control group. Methods: Consecutive cryptogenic ischemic strokes and trauma patients were identified. Additional inclusion criteria required age 18-60 years and availability of head/neck computed tomography (CT) angiography. CT angiogram (CTA) neck images were evaluated independently by 2 fellowshiptrained specialists.

Hemicrania Continua Subsequent to Vertebral Artery Dissection: A Case Report
We herein report the case of a 45-year-old woman who developed a continuous hemicranial headache subsequent to vertebral artery dissection (VAD). After remission of VAD, the patient repeatedly experienced right forehead and temporal region throbbing headache, accompanied by nausea, ocular hyperemia and lacrimation of the right eye, nasal congestion, and rhinorrhea. Magnetic resonance angiography did not reveal the recurrence of dissection. Daily use of indomethacin (190.8 mg/day) showed an excellent effect on the headache, suggesting that the patient had developed hemicrania continua subsequent to VAD.

Is Artery Web Seen in Vertebral Artery?
Carotid artery web has been frequently reported. However, the vertebral artery web has been less reported. It is difficult and seldom to diagnose vertebral artery web with noninvasive examinations. Here, we present a case of asymptomatic vertebral artery web diagnosed by ultrasound and confirmed by digital subtraction angiography.

Enlargement of a Middle Cerebral Artery Aneurysm after Intra-Aneurysmal Embolization with Parent Artery Preservation for an Ipsilateral Large Internal Carotid Artery Aneurysm: A Case Report
We report a 77-year-old woman with marked enlargement of a middle cerebral artery (MCA) aneurysm 4 years after the successful intra-aneurysmal embolization of an ipsilateral large internal carotid artery (ICA) aneurysm. She intially presented with right third cranial nerve palsy due to a large ICA aneurysm, 20.8 mm in diameter. Initial magnetic resonance angiography (MRA) revealed a signal decrease in the right MCA, suggesting hemodynamic disturbance based on the contrast pooling in the right large ICA aneurysm exhibiting “Windkessel phenomenon”.

Bilateral Limb-Shaking Transient Ischemic Attacks
We describe the case of a 69 year-old man who presented with repeated episodes of irregular jerking movements in the bilateral upper and lower extremities, precipitated by standing up. Cerebral angiograms revealed occlusion of both internal carotid arteries, and the patient's symptoms responded to targeted blood pressure management. Physicians should be mindful of bilateral limb-shaking TIAs when presented with bilateral paroxysmal events that can mimic seizures or orthostatic hyperkinesia.

Hypoglossal Nerve Palsy due to Compression by a Persistent Primitive Hypoglossal Artery: Case Report
A 51-year-old Japanese woman was admitted to our hospital because of speech difficulty following severe headache. Neurological examination showed dysarthria and tongue weakness on the right side, indicating right hypoglossal nerve palsy. Needle electromyography of the right side of the tongue showed fibrillation potentials. Magnetic resonance angiography and computed tomography angiography revealed a right, persistent, primitive hypoglossal artery (PPHA) that met Lie's diagnostic criteria. Digital subtraction angiography showed an extended PPHA with irregular caliber in the portion running through the right hypoglossal canal.

Bihemisphere Ischemia Due to a Unilateral Lesion: A Case Report
We present the case of a 70-year-old man with multiple acute/subacute bilateral infarcts. The patient was found to have stenosis of the left internal carotid artery secondary to herpes zoster ophthalmicus vasculopathy, with involvement of the left proximal middle and anterior cerebral arteries. Angiographic studies also revealed A1 segment aplasia of the right anterior cerebral artery (ACA), thus indicating dependence on the left-sided circulation for perfusion of the bilateral ACA vascular territory.

Cervical Posterior Spinal Artery Syndrome Caused By Spontaneous Vertebral Artery Dissection: Two Case Reports and Literature Review
Herein, we described 2 patients with posterior spinal artery syndrome (PSAS) caused by vertebral artery dissection. The patients complained of sudden neck pain or walking instability. Neurological examination revealed sensory loss, muscle weakness, and sensory ataxia. Angiography showed double lumen sign or intimal flap in the vertebral artery. T2-weighted imaging and diffusion-weighted imaging of MRI showed a hyperintense lesion in the dorsal side of the cervical spinal cord at different times after onset.
