Establishment of a Rat Model of Superior Sagittal-Sinus Occlusion via a Thread-Embolism Method.

J Vis Exp 2021 Jul 4(173). Epub 2021 Jul 4.

Department of Neurosurgery, the First Affiliated Hospital of Wenzhou Medical University;

The mechanisms contributing to the natural onset of cerebral venous sinus thrombosis (CVST) are mostly unknown, and a variety of uncontrollable factors are involved in the course of the disease, resulting in great limitations in clinical research. Therefore, the establishment of stable CVST animal models that can standardize a variety of uncontrollable confounding factors have helped to circumvent shortcomings in clinical research. In recent decades, a variety of CVST animal models have been constructed, but the results based on these models have been inconsistent and incomplete. Read More

Department of Pediatric Gastroenterology, Sanjay Gandhi Post-Graduate Institute of Medical Sciences, Raebareily Road, Lucknow, 226014, Uttar Pradesh, India.

Radiological embolization is the treatment of choice in adults with visceral artery pseudoaneurysm (PSA) and gastrointestinal bleeding, but pediatric data is scanty. We analyzed the etiology, clinical presentation, and outcome of radiological intervention in children with PSA of celiac (CA) or superior mesenteric artery (SMA) branches. Electronic records of children with PSA of CA or SMA branches were reviewed and data on clinical and laboratory profile, radiological intervention, and outcome was recorded. Read More

Pediatric middle meningeal artery embolization for chronic subdural hematoma: A case report.

Surg Neurol Int 2021 25;12:239. Epub 2021 May 25.

Department of Neurosurgery, Medical College of Wisconsin, Milwaukee, Wisconsin, United States.

Background: The most common neuroradiological finding in pediatric nonaccidental trauma (NAT) is subdural hematoma (SDH). Management options for pediatric SDH range from conservative clinical surveillance to craniotomy or decompressive craniectomy. The middle meningeal artery (MMA) indirectly feeds the hematoma; thus, MMA embolization is an alternative or adjunct to current surgical treatments in adults. Read More

Radiation Therapy Improves Local Control in Juvenile Nasopharyngeal Angiofibroma following Disease Progression after Embolization and Surgical Resection: A Case Report.

Case Rep Oncol 2021 May-Aug;14(2):739-745. Epub 2021 May 27.

Department of Radiation Oncology, University of Nebraska Medical Center, Omaha, Nebraska, USA.

Juvenile nasopharyngeal angiofibroma (JNA) is a relatively uncommon, benign neoplasm of the nasopharynx that can be very difficult to diagnose early due to inconspicuous and seemingly harmless presenting symptoms. Early diagnosis and treatment of JNA are essential for a good prognosis. JNA typically responds well to radiation therapy (RT), but when it does not, the most appropriate next course of action has not been readily defined due to the limited occurrence and experience with this neoplasm.

Characteristics and surgical outcomes of pediatric intracranial aneurysms in Romania.

Turk Neurosurg 2021 Feb 5. Epub 2021 Feb 5.

University of Medicine and Pharmacy Carol Davila, Department of Neurosurgery, Bucharest, Romania.

Aim: Pediatric aneurysms are rare, occurring in under 5% of cases, and their clinical presentation, rupture probability, location, and outcome differ from those in adults. The present study aimed to analyze the demographic characteristics and surgical outcomes of the largest series of patients with pediatric aneurysms reported in Romania, in consideration of the primary factors that lead to good long-term outcomes. Given that all cases involved ruptured aneurysms, we also investigated the ability of microsurgical clipping to prevent massive hemorrhage and aggravation of neurological deficits. Read More

Bilateral Traumatic Carotid-Cavernous Fistula in a Child: Corkscrew Eyelid Vessels as an Indicator of Severe Congestion.

Turk Neurosurg 2021 ;31(4):654-657

Suleyman Demirel University, Department of Ophthalmology, Isparta, Turkey.

An 11-year-old girl presented with bilateral traumatic caroticocavernous fistula associated with corkscrew eyelid vessels, which were considered indicators of severe congestive disease in this case. Coil embolization was performed; similar to other congestive findings such as proptosis, orbital bruit, increased intraocular pressure, congested scleral and retinal vessels, engorged eyelid vessels resolved immediately after coil embolization. This pediatric case is unique given the caroticocavernous fistula was bilateral and was associated with prominent dilatation of the eyelid vessels, named for the first time as corkscrew eyelid vessels.
