We report a rare case of adult pial arteriovenous fistula (PAVF) treated with preoperative embolization and surgical excision. A 26-year-old man presented with sudden headache and vomiting. CT demonstrated a subcortical hemorrhage in the left temporal lobe. Cerebral angiograms revealed a PAVF. He was treated with endovascular embolization by n-buty...

Objective: The efficacy and safety of aspiration thrombectomy using Penumbra catheter with acute large vessel occlusion in the anterior circulation have been reported in previous studies. In some cases, the carotid siphon (CS) is elongated, and with this anatomy, especially where there is bifurcation of the ophthalmic artery (OA), navigation of Pen...

Introduction : Neural tube defects are usually observed at the brain and lumbosacral levels. We report a case of adult cervical spina bifida occulta that led to myelopathy. Case presentation : A 66-year-old woman presented with 5-month history of pain from the right occipital region to the upper limb, dullness of the bilateral upper limbs, numbness...
Article
Cervical foraminal canal stenosis is a common disease, but any relationships between the measurement values of cervical foraminal canals and clinical symptoms have yet to be explored. We aim to determine a numerical cutoff point of cervical foraminal bony canal size that does not lead to radiculopathy so as to establish criteria for the surgical in...

Objective: This study evaluated the efficacy of middle meningeal artery (MMA) embolization for organized chronic subdural hematoma (OCSDH). Methods: Between 2013 and 2017 at our institution, 11 consecutive patients with 14 OCSDH lesions required MMA embolization, accounting for 4.5% of the 314 patients treated for chronic subdural hematoma (CSDH) i...

Objective: We describe a case of de novo dural arteriovenous fistula (dAVF) developed after bilateral neck clipping for middle cerebral artery (MCA) aneurysms, treated with transarterial embolization (TAE) using liquid materials. Case Presentation: A 60-year-old man underwent neck clipping for a right ruptured MCA aneurysm, and a left unruptured MC...
Article
Tentorial dural arteriovenous fistula(dAVF)is classified as Cognard 4 with a high risk of aggressive feature, such as intracranial hemorrhage, venous infarction, and intracranial hypertension. We report a rare case presenting with ocular symptoms caused by tentorial dAVF. A 59-year-old man presented with progressive chemosis and exophthalmos of his...

Objective: Plaque protrusion is one of the current problems with carotid artery stenting (CAS) for carotid artery stenosis, and it may induce delayed postprocedural cerebral infarction. In this study, we evaluate the possibility of using three-dimensional rotational angiography (3DRA) to examine the stent lumen during CAS. Methods: First, as a basi...
Article
Recently, endovascular therapy (EVT) for acute ischemic stroke has been developed to enhance early recanalization in patients who do not respond to intravenous recombinant tissue plasminogen activator (rt-PA). However, the efficacy of EVT remains uncertain. We compared clinical outcomes in patients treated with intravenous rt-PA alone (t-PA group;...

... Many studies have reported catheters getting caught on the "ophthalmic ledge"-the point at which the ophthalmic artery takes off from the carotid siphon (20,58). This is commonly referred to as the "ledge effect" (59)(60)(61) and can also be seen as catheters get stuck at the posterior communicating artery or the anterior choroidal artery ostia. This challenge is particularly relevant for large-bore aspiration catheters where a larger difference between the inner diameter of the outer catheter and the inner catheter results in a step that catches at bends or branching vessels. ...
... Throughout the articles reviewed here, no pure quantitative classifications were found. The quantitative approaches in the included MRI studies all tried to define cutoff points for clinical significant symptoms in accordance with the CT-based study by Ozaki et al. [28]. ...
... In contrast to other groups of parasellar AVF, SPS dural AVFs rarely drain into the CS. 28,30) Although Toki et al. 30) reported tentorial dural AVF in this location with drainage to the CS, the drainage route to the CS was not the direct venous route of the medial part of the SPS, it was the petrosal vein, the transverse pontine vein (TPV), and the bridging vein between the TPV and CS. One reason for the rarity of drainage to the CS is the anatomical variety of the SPS. ...
