Thrombus Extruded From the Re-Entry Point of an Aortic Dissection in the Common Carotid Artery.

This case highlights the fact that in Stanford type A aortic dissection, there are cases of re-entry points in the common carotid artery from which thrombus protrudes. If it is a thrombus, there is a possibility of embolization, requiring immediate therapeutic intervention.

Covered stent deployment for a recurrent cervical internal carotid artery aneurysm referencing angioscopy: illustrative case.

Background: Extracranial carotid artery aneurysms (ECAAs) are rare, and treatment guidelines are lacking. Few reports on endovascular treatments performed for ECAAs exist.

Observations: A 73-year-old woman with a left giant cervical internal carotid artery aneurysm was treated with overlapping closed-cell stents.

Comparison Between Cz-C3/C4 and C3-C4 Montages to Protect Against Peripheral Stimulation in Transcranial Facial Motor-Evoked Potential Monitoring.

Introduction: In facial motor-evoked potential monitoring, efforts to reduce peripheral stimulation are necessary because it can cause false-negatives. The effects of peripheral stimulation on Cz-C3/C4 and C3-C4 montages were compared.

Methods: Facial motor-evoked potentials were recorded from bilateral orbicularis oculi (Oculi) and oris (Oris) muscles.

Case report: Usefulness of angioscopy in determining antiplatelet drug reduction after carotid artery stenting.

We report a case in which neointima was confirmed by angioscopy and antiplatelet drug administration was reduced 2 months after carotid artery stenting (CAS). A patient in their 80s was scheduled to undergo resection for renal cancer; however, he also had right cervical internal carotid artery stenosis. Because this was a risk for general anesthesia, CAS was performed after first starting dual antiplatelet therapy.

Coil Embolization of Unruptured Distal Anterior Cerebral Artery Aneurysm Using a Marathon Microcatheter.

Marathon is rarely used in coil embolization for an aneurysm; particularly, there have been no reports about distal anterior cerebral artery aneurysms. We have reported a case of successful use of Marathon in coil embolization in case of a distal anterior cerebral artery aneurysm. The patient was an 83-year-old woman.

Cerebral vasospasm after coil embolization for unruptured anterior communicating artery aneurysm: illustrative case.

Background: Compared with several reports of cerebral vasospasm after clipping for unruptured cerebral aneurysm, only one study to date has reported cerebral vasospasm after coil embolization. Herein, the authors report a rare case of cerebral vasospasm after coil embolization for unruptured cerebral aneurysm.

Observations: A 58-year-old woman with an unruptured anterior communicating artery aneurysm was referred to our department.

A Novel Approach for Transvenous Embolization of Dural Arteriovenous Fistula Using a Balloon and a Coil as Walls: Case Presentation.

Background: Transvenous embolization (TVE) for dural arteriovenous fistula (DAVF) is difficult depending on an accessible route. Reported herein is a case of transvenous embolization using a balloon and a coil as "walls." .

Bilateral Magnetic Resonance Imaging-Guided Focused Ultrasound Thalamotomy for Essential Tremor.

Introduction: Essential tremor is the most common movement disorder in adults. Bilateral symptoms are typical; however, bilateral thalamotomy for essential tremor is associated with a high probability of adverse events. We retrospectively investigated the efficacy and safety of staged bilateral ventral intermediate nucleus thalamotomy for refractory essential tremor using magnetic resonance imaging-guided focused ultrasound.

4-Hydroxyl-2-Nonenal Localized Expression Pattern in Retrieved Clots is Associated with Large Artery Atherosclerosis in Stroke Patients.

Objectives: The relationship between stroke etiology and clot pathology remains controversial.

Materials And Methods: We performed histological analysis of clots retrieved from 52 acute ischemic stroke patients using hematoxylin and eosin staining and immunohistochemistry (CD42b and oxidative/hypoxic stress markers). The correlations between clot composition and the stroke etiological group (i.

Feasibility and Efficacy of a 9-Fr Balloon-Guiding Catheter Sheathless Insertion to Reduce Access Site Complications During Mechanical Thrombectomy for Acute Ischemic Stroke.

Objective: A 9-French (Fr) sheath is routinely used during mechanical thrombectomy (MT) for treating acute ischemic stroke (AIS). However, the use of a large sheath is a risk factor for access site complications (ASCs). Previous studies focused on preventing intracranial complications, and only a few have explored ASCs.

What factors impact the clinical outcome of magnetic resonance imaging-guided focused ultrasound thalamotomy for essential tremor?

Objective: Magnetic resonance imaging-guided focused ultrasound (MRgFUS) is a novel and useful treatment for essential tremor (ET); however, the factors impacting treatment outcome are unknown. The authors conducted this study to determine the factors affecting the outcome of MRgFUS.

Methods: From May 2016 through August 2017, 15 patients with ET were admitted to Ohnishi Neurological Center and treated with MRgFUS.

Pharyngolaryngeal ulcers associated with the improper use of alendronate.

Bisphosphonates can cause mucosal irritation. Although esophageal ulceration is a well-recognized adverse effect of bisphosphonates, pharyngolaryngeal ulcers associated with the improper use of oral bisphosphonates have rarely been described. A previously healthy 78-year-old woman presented with refractory pharyngolaryngeal ulcers.

Resolution of Trigeminal Neuralgia After Transvenous Embolization of a Cavernous Sinus Dural Arteriovenous Fistula.

Background: Trigeminal neuralgia (TN) resulting from a dural arteriovenous fistula (DAVF) are rare. A case of cavernous sinus dural arteriovenous fistula (CSDAVF) in a patient with TN that resolved immediately after transvenous embolization (TVE) is described.

Case Description: A 75-year-old woman presented with continuous facial pain.

Lung adenocarcinoma in a patient with plasmacytoma.

An increased risk of second malignancy is well recognized in patients treated for plasma cell neoplasms. However, second solid tumor is very rare in such patients. We report a case of a 68-year-old woman with plasmacytoma who developed lung adenocarcinoma.

Nonalcoholic steatohepatitis (NASH) after pancreaticoduodenectomy: association of pancreatic exocrine deficiency and infection.

Previous clinical study has demonstrated that 30-40% of patients undergoing pancreaticoduodenectomy (PD) developed hepatic steatosis. However, nonalcoholic steatohepatitis (NASH) is a little-known complication after PD. Recently we encountered two patients with PD who later developed NASH diagnosed by liver biopsy.

Extraskeletal myxoid chondrosarcoma arising from the clavicle.

This report presents an extremely rare case of extraskeletal myxoid chondrosarcoma (EMC) arising from the clavicular periosteum. To the best of our knowledge, this may be the first detailed report of its clinicopathological findings. The patient was a 48-year-old man.

Soft-tissue sarcoma mimicking large haematoma: a report of two cases and review of the literature.

We report on 2 patients with soft-tissue sarcomas mimicking large haematomas. Neither patient had a medical history of trauma or bleeding tendency. In a patient with a large leiomyosarcoma in the buttock, insufficient biopsy material from initial surgeries precluded a correct diagnosis.

Intraneural metastasis of a synovial sarcoma to a peripheral nerve.

We describe a case of intraneural metastasis of a synovial sarcoma, the first published case of a metastasis of a soft-tissue sarcoma to a peripheral nerve.
