Anterior communicating artery aneurysm with concomitant A2 segment triplication and anterior communicating artery fenestration, A rare case series on microsurgical treatment.

Introduction And Importance: There are few cases of multiple simultaneous anterior communicating artery (AComA) aneurysms with A2 triplication and AComA duplication.

Cases Presentation: (1) A fenestrated AComA with a saccular aneurysm (neck diameter 9 mm; dome height 8 mm) projecting superiorly from the distal AComA branch, as well as an anomalous artery arising from the posterior surface of the same AComA. (2) A duplicate AComA with a saccular aneurysm (neck diameter of 5 mm; dome height of 9 mm) projecting superioposteriorly from the distal AComA branch, as well as an anomalous artery arising from the anterior surface of the same AComA was diagnosed.

The association of transradial access and transfemoral access with procedural outcomes in acute ischemic stroke patients receiving endovascular thrombectomy: A meta-analysis.

Objective: There is an ongoing debate regarding the benefits of using transradial access (TRA) over transfemoral access (TFA) in endovascular therapies including endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) patients. This study sought to investigate the association of TRA and TFA with procedural success, access-site complications, first-pass reperfusion (FPR), puncture-to-recanalisation (PTR) time and hemorrhagic transformation (HT) by performing a meta-analysis.

Digital subtraction angiography in cerebrovascular disease: current practice and perspectives on diagnosis, acute treatment and prognosis.

Digital Subtraction Angiography (DSA) is the gold-standard imaging modality in acute cerebrovascular diagnosis. The role of DSA has become increasingly prominent since the incorporation of endovascular therapy in standards of care for acute ischemic stroke. It is used in the assessment of cerebral vessel patency; however, the therapeutic role of DSA from a prognostic standpoint merits further investigation.

Middle Cerebral Artery Aneurysm Clipping With Immersive 360° Virtual Reality Model: 2-Dimensional Operative Video.

This is a 50-yr-old female who presented with severe headaches and was found to have an unruptured middle cerebral artery (MCA) aneurysm. She was taken to the operating room for microsurgical clipping. Prior to surgery, an interactive 360° virtual reality (VR) model (Surgical Theatre Inc) rendered from the patient's volumetric computed tomography (CT) angiography (CTA) was used for patient education and operative planning.

Acute Neurological Care in the COVID-19 Era: The Pandemic Health System silience () Consortium Pathway.

The management of acute neurological conditions, particularly acute ischemic stroke, in the context of Coronavirus disease 2019 (COVID-19), is of importance, considering the risk of infection to the healthcare workers and patients and emerging evidence of the neuroinvasive potential of the virus. There are variations in expert guidelines further complicating the picture for clinicians in acute settings. In this light, there is a compelling need for further formulation of recommendations that compile these variations seen in the numerous guidelines present.

Rapidly Expanding Pediatric Post Radiation Brainstem Cavernoma Presenting with Singultus.

Here we present a pediatric patient status post resection of a primitive neuroectodermal tumor (PNET) with cranial/spinal radiation and development of a medullary cavernoma seven years after radiation therapy. The patient's cavernoma demonstrated rapid symptomatic growth in six weeks resulting in the presentation of intractable hiccups (singultus). The patient underwent resection of the cavernoma with cessation of the hiccups.

Migration of a ventriculo-peritoneal shunt catheter into a back incision of a patient with previous spinal fusion.

Introduction: This case examines a unique, longitudinal presentation of an abandoned, migrating VP shunt which presents as multiple complications, including a weeping abscess in the patients back. We believe that the latter complication was potentially caused by the wound from the patient's previous history of spinal fusion surgery.

Case Presentation: The patient presents with an associated type 2 Chiari malformation, hydrocephalus, and a previous history of posterior spinal fusion (T4-L5 anterior fusion and T2-L5 posterior fusion) at age 11.

Sporadic Meningioangiomatosis: A Series of Three Pediatric Cases.

Meningioangiomatosis (MA) is a rare benign, hamartomatous lesion within the leptomeninges and cerebral cortex. Three percent of intractable epileptic patients with tumor develop MA. It may be accompanied with neurofibromatosis type II, or it may occur sporadically.

Intradural lumbosacral malignant extrarenal rhabdoid tumor: a case report.

Background: Rhabdoid tumors are highly malignant tumors predominantly affecting the pediatric population. When these tumors occur outside of the kidneys, they are referred to as malignant extrarenal rhabdoid tumors (MERT), a rare highly aggressive subtype. Less commonly, these tumors involve the neuro-axis.

Endoscopic corpus callosotomy and hemispherotomy.

Object: Corpus callosotomy and hemispherotomy are conventionally performed via a large craniotomy with the aid of a microscope for children with intractable epilepsy. Primary technical considerations include completeness of disconnection and blood loss. The authors describe an endoscopic technique performed through a microcraniotomy for these procedures.

Desmoplastic infantile ganglioglioma with associated giant aneurysm—case report.

Desmoplastic infantile ganglioglioma (DIG) and supratentorial giant cerebral aneurysm are each extremely rare entities in infants. Here, we present the case of an 8-day old boy who had both of these conditions concurrently. To our knowledge, there is no previous case reported of a patient with coexisting DIG and giant aneurysm.

Epidural spinal cord compression in a patient with blue rubber bleb nevus syndrome.

Blue rubber bleb nevus syndrome (BRBNS) can present with vascular malformations throughout the body, especially in the gastrointestinal tract. Spinal cord compression from these lesions is rare, particularly in the pediatric population. The authors report a case of BRBNS involving an 18-year-old female patient who presented with back pain and an epidural thoracic mass with cord compression.

Symptomatic cerebral vasospasm following resection of a medulloblastoma in a child.

Background: Vasospasm may occur following intracranial tumor resection but is uncommon following resection of tumors in the posterior fossa.

Methods: Case report.

Results: Here, we report an unusual pediatric case of symptomatic cerebral vasospasm following resection of a posterior fossa medulloblastoma in a 10-year-old child.

Pallidal deep brain stimulation for primary dystonia in children.

Background: Deep brain stimulation (DBS) at the internal globus pallidus (GPi) has replaced ablative procedures for the treatment of primary generalized dystonia (PGD) because it is adjustable, reversible, and yields robust clinical improvement that appears to be long lasting.

Objective: To describe the long-term responses to pallidal DBS of a consecutive series of 22 pediatric patients with PGD.

Methods: Retrospective chart review of 22 consecutive PGD patients, ≤21 years of age treated by one DBS team over an 8-year period.

Treatment of ruptured lenticulostriate artery aneurysms.

Object: Lenticulostriate artery (LSA) aneurysms are rarely reported in the literature, making management decisions challenging. Conservative, endovascular, and surgical treatments have been described primarily through case reports and reports of individual authors' experiences. The purpose of this study is to report neurological outcomes in a single-institution experience of ruptured lenticulostriate aneurysms treated surgically.
