Predictors of a favorable outcome after successful recanalization in patients with cerebral major vessel occlusion
【Background】Although tissue-plasminogen-activator (tPA) and endovascular treatment (EVT) were reported to be useful for recanalization in patients with major vessel occlusion (MVO), the outcome in some patients with recanalization was unfavorable. We could detect prolongation of the ipsilateral posterior cerebral artery to the ischemic side on magnetic resonance angiography (MRA) in some patients (ipsilateral-PCA sign). We investigated the predictors including radiological findings for a favorable outcome after successful recanalization.

Clipping in Awake Surgery as End-Stage in a Complex Internal Carotid Artery Aneurysm After Failure of Multimodal Endovascular and Extracranial-Intracranial Bypass Treatment
Intracranial carotid artery aneurysm can be treated via microsurgical or endovascular techniques. The optimal planning is the result of the careful patient selection through clinical, anatomic, and angiographic analysis.

A Case of Ruptured Vertebrobasilar Junction Aneurysm Associated with Subclavian Steal Phenomenon
A 77-year-old woman with arteriovenous shunt for hemodialysis in the left forearm suffered from subarachnoid hemorrhage due to the rupture of a saccular aneurysm located on the left lateral wall of vertebrobasilar junction. Her left subclavian artery was severely stenosed and subclavian steal phenomenon was demonstrated on the digital subtraction angiography. Embolization of the parent artery including the aneurysm using detachable coils resulted in the successful obliteration of the aneurysm through the revascularized left subclavian artery.

The Pathophysiology of Watershed Infarction: A Three-Dimensional Time-of-Flight Magnetic Resonance Angiography Study
Most of the time, watershed infarcts (WIs) involve steno-occlusive carotid disease. The pathophysiological mechanism could be predicted by their pattern: internal WIs (IWIs) are thought to be due to hemodynamic impairment in contrast to cortical WIs (CWIs), which are more likely to be caused by microembolic phenomena. We used a 3D time-of-flight (TOF) magnetic resonance angiography (MRA) study to assess this hypothesis.

In Response to Spinal Vascular Malformations in Children
We appreciate Dr. Pearl and Dr. Gailloud's interest in our case report of a then 3-year-old child who presented with subarachnoid hemorrhage in the setting of a spinal arteriovenous malformation (AVM). Digital subtraction angiography of the left T11 segmental artery revealed a spinal dural arteriovenous fistula (DAVF) with the fistulous connection located at the level of T11 at the neural foramen. There appeared to be a single feeding artery with venous egress. There was a large associated venous varix.

Successful Resection of a Growing Distal Medial Lenticulostriate Artery Pseudoaneurysm Presenting with Isolated Intraventricular Hemorrhage
We report a very rare case of the isolated IVH due to the rupture of the distal medial LSA pseudoaneurysm that was not visible at the initial angiography but later emerged and grew.

Comparison of Rates of Growth between Unruptured and Ruptured Aneurysms Using Magnetic Resonance Angiography
Growth is a key risk factor for rupture of unruptured cerebral aneurysms. There are few reports of investigations into the actual growth of ruptured intracranial aneurysms. The aim of the present study was to ascertain the risk of rupture of aneurysms based on the growth of unruptured and ruptured aneurysms.

Isolated Internal Carotid Artery Thrombus and Cerebral Infarction in a Patient with Necrotizing Pancreatitis: Case Report
We report a case of a patient presenting with right arm weakness, slurred speech, and altered mental status in the setting of acute on chronic pancreatitis. The patient was found to have scattered left cerebral hemisphere cortical infarctions, and catheter angiography confirmed the presence of intraluminal left ICA thrombus, with no evidence of atherosclerotic disease in the cervical or intracranial vasculature.

Agenesis of the Left Internal Carotid Artery Associated with Dolichoectatic Intracranial Arteries
A 28-year-old man without a significant medical history visited our hospital complaining of a headache. Computed tomography (CT) demonstrated thick, calcified vertebral artery (VA) and basilar artery (BA), despite the patient being young. Magnetic resonance angiography demonstrated the absence of the left internal carotid artery (ICA). The right ICA, the bilateral VA, and the BA were well developed and dolichoectatic. CT revealed the absence of the carotid canal on the left side. The condition was diagnosed as congenital agenesis of the left ICA with dolichoectatic changes in 3 other arteries.

Cerebral Infarcts by Nonbacterial Thrombotic Endocarditis Associated with Adenomyosis: A Case Report
We report a case of multiple embolic cerebral infarcts associated with nonbacterial thrombotic endocarditis (NBTE) in a patient with adenomyosis. The patient presented with dysarthria, left perioral sensory change, and left-hand weakness. Magnetic resonance imaging revealed multiple vascular territory infarctions involving the bilateral cerebellum and the right precentral gyrus. Magnetic resonance angiography was normal. d-Dimer, carbohydrate antigen (CA) 19-9, and CA125 levels were elevated. Abdominal and pelvic computed tomography with iodine contrast enhancement revealed a huge adenomyosis with left ovarian cyst.

Letter to the Editor regarding “Comparison of Rates of Growth between Unruptured and Ruptured Aneurysms Using Magnetic Resonance Angiography”
We would like to commend the authors Watanabe et al. for their study assessing the rate of growth of unruptured versus ruptured aneurysms on magnetic resonance angiography (MRA).1 The natural history of small, unruptured intracranial aneurysms (UIAs) is not well understood, and small UIAs have low growth and rupture rates reported in the literat ure.2 We have a few questions for the authors and concerns about the conclusions.

Comparison of Rates of Growth between Unruptured and Ruptured Aneurysms Using Magnetic Resonance Angiography JSCVD-D-17-01123
1) As you mentioned, there are possibilities of changing the size of aneurysms just after rupture. Actually, in retrospective study, it is impossible precisely to evaluate the size of aneurysms just before rupture against just after rupture. In our study, the period from magnetic resonance imaging before aneurysm rupture to subarachnoid hemorrhage was variable in all patients.
