REVIEW
Joseph T Church, Marcus D Jarboe
Vascular access procedures are an important and frequent component of the day-to-day practice of the pediatric surgeon. Most access procedures can be performed percutaneously via Seldinger or modified Seldinger technique and are aided by technology, such as ultrasound and fluoroscopy. Complications, such as infection, do occur, and the pediatric surgeon should be able to diagnose and treat these when they arise. The indications, techniques, and complications of vascular access are covered in this article.

OBJECTIVES: The aim of this study was to evaluate the effectiveness of UltraBLOX™ radiation attenuating hand cream during lengthy cardiac catheterization procedures in children. BACKGROUND: The hands of interventional cardiologists receive high doses of radiation due to their proximity to the X-ray beam. Radiation attenuating gloves have about a 26% attenuation rate, but reduce dexterity and tactile sensation. The UltraBLOX™ cream is a new FDA-approved X-ray attenuating cream that can be applied to the operator's hands for radio-protection...

Endomyocardial biopsy (EMB) with fluoroscopy is used for rejection surveillance in pediatric heart transplantation. Lowering frame rate may reduce radiation, but decreases temporal resolution and image quality. We undertook a quality initiative reducing frame rate from 10 frames per second (FPS) to 5 FPS. To assess whether lowering frame rate can reduce radiation exposure without compromising safety, data on EMBs from 9/2009 to 4/2013 without angiography or intervention were reviewed. Effective dose was calculated from dose area product (DAP) and fluoroscopy time...

BACKGROUND: Recent studies have shown an increase in morbidity associated with button battery ingestions in children. OBJECTIVE: To perform a comprehensive, imaging-focused review of all patients with confirmed button battery ingestions/insertions imaged at our institution in the last 15 years. MATERIALS AND METHODS: Radiology reports from Jan. 1, 2000, to July 12, 2015, were searched for the terms "battery" and "batteries." Confirmed cases of battery ingestion/insertion for which images were available were reviewed...

BACKGROUND: Although practice patterns vary, scout radiographs are often routinely performed with pediatric fluoroscopic studies. However few studies have evaluated their utility in routine pediatric fluoroscopy. OBJECTIVE: To evaluate the value of scout abdomen radiographs in routine barium or water-soluble enema, upper gastrointestinal (GI) series, and voiding cystourethrogram pediatric fluoroscopic procedures. MATERIALS AND METHODS: We retrospectively evaluated 723 barium or water-soluble enema, upper GI series, and voiding cystourethrogram fluoroscopic procedures performed at our institution...

Brandon M Green, Joseph D Stone, Robert W Bruce, Nicholas D Fletcher
BACKGROUND: Flexion-type supracondylar humerus fractures are much more uncommon than their extension-type counterparts. Instability in elbow flexion renders traditional closed techniques inadequate and often results in the need for open reduction. We present a simple technique for closed reduction using a transolecranon pin for temporary stability. METHODS: A retrospective review of 9 patients treated with a transolecranon pin technique for a flexion-type supracondylar humerus fracture was performed...

INTRODUCTION: Langerhans cell histiocytosis (LCH) occurs rarely in the spine of adults. The radiological findings usually resemble vertebral tumors. Etiology of LCH has not been clearly established yet. Therapeutic approaches are still controversial. We describe a case of LCH in an adult spine. CASE DESCRIPTION: A patient who presented with low back pain had an osteolytic lesion in the L1 vertebral body without neurological deficits, and fluoroscopy-guided needle biopsy of the L1 vertebral body was performed...

BACKGROUND: The present objective was to compare medial mini-open and percutaneous treatment of pediatric supracondylar fractures according to fluoroscopy time, duration of surgery, and iatrogenic ulnar nerve injury. METHODS: A total of 104 Gartland type III supracondylar humerus fractures were prospectively evaluated between 2011 and 2013. Patients were divided into 2 groups according to type of fixation. In Group A (41 patients), medial pin was inserted with mini-open incision with 2 lateral pins inserted percutaneously...

A survey about radiation protection in pediatric radiology was conducted among 22 general and seven children's hospitals in the Netherlands. Questions concerned, for example, child protocols used for CT, fluoroscopy and x-ray imaging, number of images and scans made, radiation doses and measures taken to reduce these, special tools used for children, and quality assurance issues. The answers received from 27 hospitals indicate that radiation protection practices differ considerably between general and children's hospitals but also between the respective general and children's hospitals...

BACKGROUND: Life-threatening midgut volvulus usually occurs in infants with malrotation and requires rapid diagnosis and surgical treatment to prevent bowel necrosis and death. However, because of the low frequency of upper gastrointestinal studies performed in infants younger than 1 month, many diagnostic radiology residents finish their residency training having limited or no opportunity to perform or observe an upper gastrointestinal (GI) series for evaluation of bilious emesis in a neonate...

OBJECTIVE: The aim of the study was to calculate the effective dose during fluoroscopy-guided pediatric interventional procedures of the liver in a phantom model before and after adjustment of preset parameters. METHODS: Organ doses were measured in three anthropomorphic Rando-Alderson phantoms representing children at various age and body weight (newborn 3.5kg, toddler 10kg, child 19kg). Collimation was performed focusing on the upper abdomen representing mock interventional radiology procedures such as percutaneous transhepatic cholangiography and drainage placement (PTCD)...

Children are more radio sensitive than adult. This study aims to assess radiation doses and the associated hazards to pediatric during cardiac catheterization procedures. Radiation dose for 112 patients was estimated in the biggest cardiac center in Sudan. The median KAP in Gy cm(2), CK in mGy, number of frames and fluoroscopy time in minutes were (4.6, 29.0, 340.4, 13.5) and (6.0, 35.0, 318, 9.8) for the diagnostic and therapeutic cardiac procedures, respectively. The median (KAP in Gy cm(2), effective dose in mSv) for different age groups in the intervals of less than 1 year, 1-<5 years, 5-<10 years and 10-15 years old were (2...

Symptomatic subfibular and/or lateral talocalcaneal impingement in pediatric patients may result from an accessory anterolateral talar facet (AALTF). This impingement may cause pain and disability and may limit athletic performance in high-level athletes. We report the case of a 12-year-old female competitive gymnast who had refractory, lateral-sided right ankle pain for 4 months and underwent right ankle arthroscopic resection of the AALTF causing impingement. Standard medial and anterolateral portals with the addition of an accessory anterolateral-distal portal were used in conjunction with a 30° 2...

The aim of this study was to assess image quality and radiation dose of a biplane angiographic system with cone-beam CT (CBCT) capability tuned for pediatric cardiac procedures. The results of this study can be used to explore dose reduction techniques. For pulsed fluoroscopy and cine modes, polymethyl methacrylate phantoms of various thicknesses and a Leeds TOR 18-FG test object were employed. Various fields of view (FOV) were selected. For CBCT, the study employed head and body dose phantoms, Catphan 504, and an anthropomorphic cardiology phantom...

BACKGROUND: Intraoperative C-arm fluoroscopy and low-dose O-arm are both reasonable means to assist in screw placement for idiopathic scoliosis surgery. Both using pediatric low-dose O-arm settings and minimizing the number of radiographs during C-arm fluoroscopy guidance decrease patient radiation exposure and its deleterious biological effect that may be associated with cancer risk. We hypothesized that the radiation dose for C-arm-guided fluoroscopy is no less than low-dose O-arm scanning for placement of pedicle screws...
