Transradial access is widely used in cardiological adult interventions and less in pediatrics. In recent years, this access has become more popular in the neuroradiological community in adult patients since it has fewer complications and is more comfortable for the patient after the procedure. We present a single-center case series of 52 transradial access neurointerventions (43 angiographies and 9 therapeutic procedures) in pediatric patients, with a failure of 4 cases (7.7%) in which we could not puncture the artery, crossing over to transfemoral access. Since in five cases we did angiography followed by therapeutic intervention, thus doing only one puncture access for both procedures, then our access failure rate was 10.6%. The 34 successful transradial access solely angiographies had a median radiation exposure of 887 mGy (interquartile range 628–1352), median fluoroscopy time of 9.5 min (interquartile range 7.5–15.3), and median procedure time of 28 min (interquartile range 24–33 min) Therapeutic procedure diagnosis were: one ruptured saccular aneurysm, two juvenile nasopharyngeal angiofibromas, and five arteriovenous malformations. The transradial access neurointerventions for pediatric population older than 11 years is safe and feasible, having previous experience in adults. Younger population should be considered on a case-to-case basis, depending on ultrasound measurement of the arterial diameter and the materials available.

Abstract Background Laparoscopic resection is the most well described minimally-invasive approach for adrenalectomy. While it allows for improved cosmesis, faster recovery and decreased length of hospital stay compared with the open approach, instrument articulation limitations can hamper surgical dexterity in pediatric patients. Use of robotic assistance can greatly enhance operative field visualization and instrument control, and is in the early stages of adoption in academic centers for pediatric populations. Case presentation We present a single-institution series of pediatric adrenalectomy cases. The da Vinci Xi surgical system was used to perform adrenalectomies on three consecutive patients (ages, 2–13 years) at our center. Final pathology revealed ganglioneuroblastoma (n = 2) and pheochromocytoma (n = 1). Median operating time was 244 min (range, 244–265 min); median blood loss was estimated at 100 ml (range, 15–175 ml). Specimens were delivered intact and all margins were negative. Median post-operative hospital stay was 2 days (range, 1–6 days). All patients remain disease-free at median follow-up of 19 months (range, 12–30 months). Conclusion Our experience continues to evolve, and suggests that robotic surgery is safe, feasible and oncologically effective for resection of adrenal masses in well-selected pediatric patients.

BackgroundDiagnostic cerebral angiograms are increasingly being performed by transradial access (TRA) in adults, following data from the coronary literature supporting fewer access-site complications. Despite this ongoing trend in neuroangiography, there has been no discussion of its use in the pediatric population. Pediatric TRA has scarcely been described even for coronary or other applications. This is the first dedicated large study of transradial access for neuroangiography in pediatric patients.MethodsA multi-institutional series of consecutively performed pediatric transradial angiograms and interventions was collected. This included demographic, procedural, outcomes, and safety data. Data was prospectively recorded and retrospectively analyzed.ResultsThirty-seven diagnostic angiograms and 24 interventions were performed in 47 pediatric patients. Mean age, height, and weight was 14.1 years, 158.6 cm, and 57.1 kg, respectively. The radial artery measured 2.09+/-0.54 mm distally, and 2.09+/-0.44 mm proximally. Proximal and distal angiography were performed for both diagnostic and interventional application (17 distal angiograms, two distal interventions). Clinically significant vasospasm occurred in eight patients (13.1%). Re-access was successfully performed 11 times in seven patients. Conversion to femoral access occurred in five cases (8.2%). The only access-related complication was a small asymptomatic wrist hematoma after TR band removal.ConclusionsTransradial access in pediatric patients is safe and feasible. It can be performed successfully in many cases but carries some unique challenges compared with the adult population. Despite the challenge of higher rates of vasospasm and conversion to femoral access, it is worth exploring further, given the potential benefits.

Robotic assisted neurosurgery has become increasingly utilized for its high degree of precision and minimally invasive approach. Robotic stereotactic assistance (ROSA®) for neurosurgery has been infrequently reported in the pediatric population. The goal of this case series was to describe the clinical experience, anesthetic and operative management, and treatment outcomes for pediatric patients with intractable epilepsy undergoing ROSA® neurosurgery at a single-center institution. Patients who underwent implantation of stereoelectroencephalography (SEEG) leads for intractable epilepsy with ROSA® were retrospectively evaluated between August 2016 and June 2018. Demographics, perioperative management details, complications, and preliminary seizure outcomes after resective or ablative surgery were reviewed. Nineteen children who underwent 23 ROSA® procedures for SEEG implantation were included in the study. Mean operative time was 148 min. Eleven patients had subsequent resective or ablative surgery, and ROSA® was used to assist with laser probe insertion in five patients for seizure foci ablation. In total, 148 SEEG electrodes were placed without any perioperative complications. ROSA® is minimally invasive, provides superior accuracy for electrode placement, and requires less time than traditional surgical approaches for brain mapping. This emerging technology may improve the perioperative outcomes for pediatric patients with intractable epilepsy since large craniotomies are avoided; however, long-term follow-up studies are needed.

Object The majority of pediatric craniopharyngiomas are treated using a transcranial approach. Although there is an increasing acceptance of transsphenoidal resection in adults, there are few reports describing this approach in the pediatric population. The purpose of this study is to report the outcomes after transsphenoidal surgery in a consecutive series of pediatric patients with craniopharyngiomas treated at a single institution with the goal of gross-total resection (GTR). Methods Twenty-three patients with pathologically proven craniopharyngiomas were identified who were 18 years of age or less at the time of surgery. The medical records and imaging studies of the patients were retrospectively reviewed. One patient who was lost to follow-up after surgery was excluded. Results Among the 22 patients included in the study, 11 underwent transsphenoidal surgery as the primary procedure and 11 underwent transsphenoidal surgery as a secondary procedure after a previous procedure. All patients had at least some sellar component to their tumor and all had either anterior or posterior pituitary dysfunction at presentation. In the entire cohort, a GTR was achieved in 15 (68%) of 22 patients, a radical subtotal resection in 4 (18%) of 22 patients, a subtotal resection in 1 patient, and a partial resection in 2 patients. The degree of resection was higher in the primary transsphenoidal group. After a mean follow-up of 82 months, 4 patients (18%) experienced recurrence. Recurrence occurred in 13% after GTR compared with 28.5% after all other degrees of resection. Tumor recurred in 9% of the primary transsphenoidal group and in 30% of patients who had undergone other therapies prior to the transsphenoidal operation. No patient who had panhypopituitarism experienced a gain of function postoperatively, 67% developed new panhypopituitarism, and 56% experienced new diabetes insipidus. Vision improved or normalized in 9 (64%) of 14 patients presenting with visual loss. Complications included 1 death 3 weeks postoperatively, 2 CSF leaks, and new obesity in 37%. Conclusions Transsphenoidal resection of pediatric craniopharyngiomas results in a high rate of both visual improvement and GTR with a low associated risk of recurrence. The transsphenoidal approach should be considered in selected pediatric patients with craniopharyngioma, especially those with infradiaphragmatic origin.

The dynamic of SARS-CoV-2 and other respiratory virus in children and adolescents is relevant in clinical context. There are few studies comparing clinical course in COVID-19 (coronavirus disease) and other respiratory virus in pediatric patients. The aim of this study was to compare demographics and clinical features, exams abnormalities, and outcomes in SARS-CoV-2 and other respiratory virus infections in a pediatric population. This was a single-center prospective study, between April 17 to September 30, 2020. We evaluated 76 pediatric COVID-19 and 157 other respiratory virus infections. Rhinovirus occurred in 132/157(84%). COVID-19 patients were significantly older, had more fever (69% versus 50%; p=0.01), pneumonia (22% versus 5%; p<0.01), myalgia (29% versus 8%; p=0.001), headache (31% versus 14%; p=0.01) and worse outcomes than those with other respiratory virus infections. Our data emphasizes differences in clinical presentation and outcomes between pediatric COVID-19 and rhinovirus infections.

ABSTRACTObjectivesA kind of pneumonia caused by unknown causes that occurred in Wuhan, Hubei, China in December 2019, was reported as a result of novel coronavirus infection on January 7, 2020, and then WHO named it COVID-19. To compare the difference of epidemiology and clinical characteristics between asymptomatic COVID-19 infections and moderate type of confirmed cases.MethodsRetrospective, single-center cohort study of COVID-19 involving 52 infections of both 26 asymptomatic and 26 moderate type of confirmed cases in the recovery stage at Guizhou Provincial Staff Hospital in Guiyang, China, from January 29, to March 31, 2020; final date of follow-up was April 22. This study was registered in Chinese Clinical Trial Registry Center. Documented the asymptomatic COVID-19 infections and moderate type of confirmed cases. Epidemiological, demographic, clinical, laboratory, radiological, and treatment data were collected and analyzed. Epidemiological and clinical characteristics of asymptomatic COVID-19 infections and moderate type of confirmed cases were compared.ResultsThe median treatment cycle of asymptomatic COVID-19 infections was 16 days (interquartile range, 11-20 days) and longer than 13 days (interquartile range, 10-15 days) of moderate type of confirmed cases (p=0.049). The median incubation period of asymptomatic COVID-19 infections was 10 days (interquartile range, 0-21 days), while the control group was 7 days (interquartile range, 1-15 days) (p=0.27). On the initial chest computerized tomography (CT) check, 18 (69.2%, 18/26) asymptomatic COVID-19 infections were no imaging changes, which was of no significance compared with 12 (46.2%, 12/26) patients with moderate type of confirmed patients (p=0.092).ConclusionsIn this single-center study, we found that asymptomatic COVID-19 infections have longer treatment cycle than those moderate type of confirmed cases.Key PointsIn this single-center case series involving 52 infections with asymptomatic and moderate type of COVID-19 cases, asymptomatic COVID-19 infections have longer treatment cycle than those moderate type of confirmed patients.

OBJECTIVEThe transradial approach (TRA) has been widely adopted by interventional cardiologists but is only now being accepted by neurointerventionalists. The benefits of the TRA over the traditional transfemoral approach (TFA) include reduced risk of adverse clinical events and faster recovery. The authors assessed the safety and feasibility of the TRA for neurointerventional cases in the pediatric population.METHODSPediatric patients undergoing cerebrovascular interventions since implementation of the TRA at the authors’ institution were retrospectively reviewed. Pertinent patient information, procedure indications, vessels catheterized, fluoroscopy time, and complications were reviewed.RESULTSThere were 4 patients in this case series, and their ages ranged from 13 to 15 years. Each patient tolerated the procedure performed using the TRA without any postprocedural issues, and only 1 patient experienced radial artery spasm, which resolved with the administration of intraarterial verapamil. None of the patients required conversion to the TFA.CONCLUSIONSThe TRA can be considered a safe alternative to the TFA for neurointerventional procedures in the pediatric population and provides potential advantages. However, as pediatric patients require special consideration due to their smaller-caliber arteries, routine use of ultrasound guidance is advised when attempting the TRA.

Background: Pigmented villonodular synovitis (PVNS) is a benign proliferative synovial disorder most commonly described to affect the knee in adults. Literature describing PVNS in the pediatric population is limited to 2 small case series and a handful of single-patient case reports. Within these studies, only 2 patients with PVNS of the hip are described. Purpose: To describe the presentation, management, and outcomes of a single-center series of pediatric patients with PVNS of the hip treated with arthroscopic synovectomy. Study Design: Case series; Level of evidence, 4. Methods: A retrospective review of consecutive pediatric patients treated for PVNS at a single institution was performed. Inclusion criteria consisted of patients younger than 19 years with surgically treated PVNS of the hip. Results: Five pediatric patients with a mean age of 11.0 years were treated for PVNS of the hip from 2011 to 2016. The mean duration of symptoms from onset to surgical treatment was 247 days (range, 3-933 days). Upon review of magnetic resonance imaging (MRI) results, radiologists included PVNS in their differential in 3 patients. Seven surgeries were performed in 5 patients. All therapeutic procedures were arthroscopic synovectomies. Nodular PVNS was present in 4 patients, and diffuse disease was present in 1 patient. At a mean 32-month follow-up (range, 12-63 months), all patients were considered to be free of recurrence based on clinical examination and/or follow-up MRI. Four patients were asymptomatic and returned to all of their previous sports activities. Conclusion: Young age at the time of diagnosis is a point to be highlighted in this cohort, and symptoms may be present for many months prior to diagnosis due to the failure to consider PVNS in children. Therefore, for patients with “atypical” presentations or lack of improvement with treatment for rheumatologic, bleeding, or infectious disorders, PVNS should be strongly considered. MRI with gradient echo sequences is the diagnostic imaging study of choice. One patient with diffuse involvement and preoperative degenerative changes showed progressive changes postoperatively. This type of PVNS may have a worse prognosis, but more diffuse cases are needed before the prognosis can be determined. Arthroscopic synovectomy following a timely diagnosis of PVNS produces good outcomes in nodular cases, with no evidence of symptomatic or radiographic disease persistence among these patients.

Purpose: To date, little attention has been directed to retinal photoreceptor migration after traumatic macular hole surgical repair in the pediatric population. The purpose of this study was to evaluate optical coherence tomography (OCT) findings in the foveae of pediatric patients with history of traumatic macular hole surgical repair. Methods: Retrospective case series of 3 eyes in 3 pediatric patients with traumatic macular hole surgical repair. Spectral domain OCT images were obtained pre- and postoperatively. Results: We report 3 cases of restoration of the ellipsoid zone with good visual acuity outcomes following macular hole closure. Conclusion: Optical coherence tomography findings of an intact ellipsoid zone may be a predictor of visual acuity and explain better surgical outcomes in the pediatric population.

BackgroundDural venous sinus stenting (VSS) is an effective treatment for idiopathic intracranial hypertension (IIH) in adult patients. There are no published series to date evaluating safety and efficacy of VSS in pediatric patients.ObjectiveTo report on procedural device selection and technique as well as safety and efficacy of VSS for pediatric patients with medically refractory IIH due to underlying venous sinus stenosis.MethodsA multi-institutional retrospective case series identified patients with medically refractory IIH aged less than 18 years who underwent VSS.Results14 patients were identified at four participating centers. Patient ages ranged from 10 to 17 years, and 10 patients (71.4%) were female. Mean body mass index was 25.7 kg/m2 (range 15.8–34.6 kg/m2). Stenting was performed under general endotracheal anesthesia in all except two patients. The average trans-stenotic gradient during diagnostic venography was 10.6 mm Hg. Patients had stents placed in the superior sagittal sinus, transverse sinus, sigmoid sinus, occipital sinus, and a combination. Average follow-up was 1.7 years after stenting. Six patients out of 10 (60%) had reduced medication dosing, 12 of 14 patients (85.7%) had improvements in headaches, two patients (100%) with pre-stent tinnitus had resolution of symptoms, and four (80%) of five patients with papilledema had improvement on follow-up ophthalmological examinations. Two patients (14.3%) developed postprocedural groin hematomas, one patient (7.1%) developed a groin pseudoaneurysm, and one patient (7.1%) had postprocedural groin bleeding. No other procedural complications occurred. Four patients (28.6%) required further surgical treatment (cerebrospinal shunting and/or stenting) after their first stenting procedure.ConclusionsThis series suggests that VSS is feasible in a pediatric population with IIH and has a low complication rate and good clinical outcomes.
