- Abstract
Background: Pediatric interventional radiology is a distinct subspecialty differing from both pediatric diagnostic radiology and adult interventional radiology. We conducted a workforce survey in 2005 to evaluate the state of pediatric interventional radiology at that time. Since then there have been many advancements to the subspecialty, including the founding of the Society for Pediatric Interventional Radiology (SPIR)., Objective: To evaluate the current state of the pediatric interventional radiology workforce and compare findings with those of the initial 2005 workforce survey., Materials and Methods: We sent a two-part survey electronically to members of SPIR, the Society for Pediatric Radiology (SPR), the Society of Chairmen of Radiology in Children's Hospitals (SCORCH) and the Society of Interventional Radiology (SIR). Part 1 focused on individual practitioners (n=177), while part 2 focused on group practices and was answered by a leader from each group (n=88). We examined descriptive statistics and, when possible, compared the results to the study from 2005., Results: A total of 177 individuals replied (a 331% increase over the first study) and 88 pediatric interventional radiology (IR) service sites responded (a 131.6% increase). Pediatric IR has become a more clinically oriented specialty, with a statistically significant increase in services with admitting privileges, clinics and performance of daily rounds. Pediatric IR remains diverse in training and practice. Many challenges still exist, including anesthesia/hospital support, and the unknown impact of the new IR residency on pediatric IR training, although the workforce shortage has been somewhat alleviated, as demonstrated by the decreased mean call from 165 days/year to 67.2 days/year., Conclusion: Pediatric interventional radiology practitioners and services have grown significantly since 2005, although the profile of this small subspecialty has changed and some challenges remain.

- Abstract
Paediatric palliative care is a distinct subspecialty that offers treatment to children with many types of illness, including oncological, neurological and respiratory problems. Paediatric interventional radiologists can make a useful contribution to symptom management as part of a multidisciplinary team. Interventions for pain management include local ablation or other treatment of painful lesions, image-guided nerve blocks and the insertion of devices for the delivery of analgesic drugs. Various techniques are also available for the management of ascites, pleural effusions and other symptomatic complications of the underlying disease process.

- Abstract
The scope for image-guided intervention in the chest is very wide and encompasses procedures in the heart, pulmonary and systemic vasculature, lungs and pleural cavities, airway, and esophagus. This review describes the most important procedures that are usually performed by radiologists. Percutaneous drainage is now the most common method of treating both empyemas and lung abscesses in children. Although most lung biopsies are carried out by other means, percutaneous biopsy and localization are important alternatives for the diagnosis of focal lung lesions. Esophageal strictures are common in children and are usually best treated by balloon dilatation. The use of retrievable or biodegradable stents has recently been introduced for refractory esophageal strictures. Similarly, balloon dilatation and stenting are now increasingly used in children with stenosis or extrinsic compression of the trachea or bronchi., (Copyright © 2011 Elsevier Inc.

Background: Arteriovenous fistulae (AVF) provide superior primary vascular access for children on chronic dialysis compared to central venous catheters (CVC). However, AVFs inevitably develop complications and will require some intervention to maintain long-term functional patency.Methods: We report an 'endovascular-first' approach to the maintenance and rescue of paediatric AVFs. Thirty interventions targeting 46 lesions in 18 children (median age 11 years [range 5-17]) were performed. Sixty-eight percent of the AVFs were brachio-cephalic fistulae, 26% brachio-basilic fistulae and 5% radio-cephalic fistulae. Immediate functional success was 86% with good dialysis adequacy (mean urea reduction ratio > 70%) at 3 months post procedure.Results: There was one significant complication, consisting of an AVF rupture which was managed with a covered stent.Conclusions: Repeated interventions may be necessary to maintain AVF patency and avoid central venous catheters. This is the largest series reported to date. [ABSTRACT FROM AUTHOR]

Purpose: Radiologically inserted gastrojejunal tubes (RGJ) and surgical jejunostomy (SJ) are established modes of jejunal feeding. The aim of the study is to review nutritional outcomes, complications and the practical consideration to enable patients and carers to make informed choice.Methods: Retrospective review of patient notes with a RGJ or SJ in 2010, with detailed follow-up and review of the literature.Results: Both RGJ and SJ are reliable modes to provide stable enteral nutrition. Both have complications and their own associated limitations.Conclusions: The choice has to be tailored to the individual patient, the social care available, the inherent medical disease and risk/benefit of repeated anaesthetic and radiation exposure. RGJ and SJ are important tools for nutritional management that achieve and maintain growth in a complex group of children. The risk and benefits should be reviewed for each individual patient.

LIVER cancer ,INTERVENTIONAL radiology ,LIVER tumors ,CHILDHOOD cancer ,CANCER chemotherapy ,PEDIATRICS ,DIAGNOSIS - Abstract
Imaging is crucial in the assessment of children with a primary hepatic malignancy. Since its inception in 1992, the PRETEXT (PRE-Treatment EXTent of tumor) system has become the primary method of risk stratification for hepatoblastoma and pediatric hepatocellular carcinoma in numerous cooperative group trials across the world. The PRETEXT system is made of two components: the PRETEXT group and the annotation factors. The PRETEXT group describes the extent of tumor within the liver while the annotation factors help to describe associated features such as vascular involvement (either portal vein or hepatic vein/inferior vena cava), extrahepatic disease, multifocality, tumor rupture and metastatic disease (to both the lungs and lymph nodes). This manuscript is written by members of the Children's Oncology Group (COG) in North America, the International Childhood Liver Tumors Strategy Group (SIOPEL) in Europe, and the Japanese Study Group for Pediatric Liver Tumor (JPLT; now part of the Japan Children's Cancer Group) and represents an international consensus update to the 2005 PRETEXT definitions. These definitions will be used in the forthcoming Trial to Pediatric Hepatic International Tumor Trial (PHITT). [ABSTRACT FROM AUTHOR]

Primary liver malignancies are rare in children. Hepatoblastoma and hepatocellular carcinoma (HCC) together represent the overwhelming majority of cases. Overall survival of hepatoblastoma approaches 80% with multimodal treatment approaches that include chemotherapy, surgery and transplantation. However, there remains a subset of children with hepatoblastoma in whom resection or transplantation is not possible. The 5-year survival for children diagnosed with HCC is less than 30% and remains a significant therapeutic challenge. The poor outcomes for children with primary liver tumors motivate investigation of new therapeutic alternatives. Interventional oncology offers a broad scope of percutaneous and transcatheter endovascular cancer therapies that might provide clinical benefits. Minimally invasive approaches are distinct from medical, surgical and radiation oncologic treatments, and in adults these approaches have been established as the fourth pillar of cancer care. Transarterial chemoembolization is a minimally invasive locoregional treatment option performed by interventional radiologists with level-I evidence as standard of care in adults with advanced liver malignancy; transarterial chemoembolization in adults has served to prolong disease-free progression, downstage and bridge patients for surgical and transplant interventions, and improve overall survival. However, while several groups have reported that transarterial chemoembolization is feasible in children, the published experience is limited primarily to small retrospective case series. The lack of prospective trial evidence has in part limited the utilization of transarterial chemoembolization in the pediatric patient population. The purpose of this article is to provide an overview of the role of interventional radiology in the diagnosis and endovascular management of hepatic malignancies in children. [ABSTRACT FROM AUTHOR]

Hepatoblastoma and hepatocellular carcinoma (HCC) are the most common pediatric liver malignancies, with hepatoblastoma occurring more commonly in younger children and HCC occurring more commonly in older children and adolescents. Although surgical resection (including transplant when necessary) and systemic chemotherapy have improved overall survival rate for hepatoblastoma to approximately 80% from 30%, a number of children with this tumor type are not eligible for operative treatment. In contradistinction, pediatric HCC continues to carry a dismal prognosis with an overall 5-year survival rate of 30%. The Paediatric Hepatic International Tumour Trial (PHITT) is an international trial aimed at evaluating both existing and emerging oncologic therapies for primary pediatric liver tumors. Interventional radiology offers a number of minimally invasive procedures that aid in diagnosis and therapy of pediatric liver tumors. For diagnosis, the PHITT biopsy guidelines emphasize and recommend percutaneous image-guided tumor biopsy. Additionally, both percutaneous and endovascular procedures provide therapeutic alternatives that have been, to this point, only minimally utilized in the pediatric population. Specifically, percutaneous ablation offers a number of cytotoxic technologies that can potentially eradicate disease or downstage children with unresectable disease. Percutaneous portal vein embolization is an additional minimally invasive procedure that might be useful to induce remnant liver hypertrophy prior to extended liver resection in the setting of a primary liver tumor. PHITT offers an opportunity to collect data from children treated with these emerging therapeutic options across the world. The purpose of this manuscript is to describe the potential role of minimally invasive percutaneous transhepatic procedures, as well as review the existing data largely stemming from the adult HCC experience.

Interventional radiology is a rapidly growing discipline in paediatrics. Many non-vascular interventional techniques may be used in the gastrointestinal tract in children. The technically simpler and more common of these may be adopted by any paediatric radiologist with an interest in interventional radiology. Other rarer and more complex techniques are currently restricted to specialist centres with a higher overall caseload. This review emphasizes the common procedures such as oesophageal dilatation, gastrostomy, insertion of transgastric jejunal feeding tubes and biopsy. Less common salivary, hepatobiliary, pancreatic and intestinal interventions are also described. [ABSTRACT FROM AUTHOR]

Fetal endoscopic tracheal occlusion (FETO) is a promising treatment for severe congenital diaphragmatic hernia, a condition that carries significant morbidity and mortality. It is hypothesised that balloon occlusion of the fetal trachea leads to an improvement in lung growth and development. The major documented complications of FETO to date are related to preterm delivery. To report a series of five infants who developed tracheomegaly following FETO. Review of all children referred with tracheomegaly to the paediatric intensive care and tracheal service at two referral centres. Five neonates presented with features of respiratory distress shortly after birth and were subsequently found to have marked tracheomegaly. Two neonates had tracheomalacia in addition. There are no previous reports in the literature describing tracheomalacia, or more specifically, tracheomegaly, as a consequence of FETO. We propose that the particularly compliant fetal airway is at risk of mechanical damage from in utero balloon occlusion. This observation of a new problem in this cohort suggests a thorough evaluation of the trachea should be performed in children who have had FETO in utero. It may be that balloon occlusion of the trachea earlier in utero (before 26 weeks’ gestation) predisposes to this condition. [ABSTRACT FROM AUTHOR]

Central venous access is increasingly becoming the domain of the radiologist, both in terms of the insertion of central venous catheters (CVCs) and in the subsequent management of these lines. This article seeks to provide an overview of the CVC types available for paediatric patients and a more detailed explanation of the spectrum of complications that may lead to catheter malfunction. A standard catheter contrast study or ‘linogram’ technique is described. The normal appearances of such a study and a detailed pictorial review of abnormal catheter studies are provided, together with a brief overview of how information from catheter investigations can guide the management of catheter complications.

Background: Image-guided core needle biopsy is widely used in paediatric oncology, but many protocols continue to discourage this practice. No published randomized studies compare image-guided needle biopsy with surgical techniques.Objective: To perform a systematic review of the literature on image-guided core needle biopsy in paediatric oncology.Materials and Methods: Several computerized databases were searched using the terms [(needle OR core) AND (biops*[ti]) AND (paediatric OR pediatric OR child OR children OR childhood OR boy OR girl)[ti]] to identify series of more than five cases of needle core biopsy for tumour diagnosis in children. Data from included studies were combined to calculate pooled estimates of adequacy, accuracy and complication rates.Results: Thirteen studies fulfilled the inclusion criteria. Overall biopsy adequacy rate (defined as sufficient to make a diagnosis) was 94% (95% CI 92-96%). The diagnostic accuracy rate in cases with adequate material (defined as achieving the correct specific diagnosis) was 94% (95% CI 92-96%). Complications requiring treatment occurred in 1%.Conclusions: Available pooled data suggest that about 95% of image-guided needle core biopsies provide an adequate sample for diagnosis of malignant disease in childhood. In such cases, the pathological diagnosis is correct in about 95%. Complications are rare. [ABSTRACT FROM AUTHOR]- Published

The treatment of hepatoblastoma is an example of the great advances made in paediatric oncology over the past few decades. Formerly a disease with a dreadful prognosis, children now have a 5-year survival rate of over 70%. This has been achieved by advances in surgical techniques and the use of chemotherapy. In future, we hope to be able to improve survival for children with high-risk tumours, and decrease the morbidity associated with treatment in the others. [ABSTRACT FROM AUTHOR]

A variety of portal vein anomalies that occur in children can be identified by US, CT, MRI and portal venography. Although these abnormalities can also occur in adults, there are certain pathological processes and aberrations within the portal system that are specific to children. Knowledge of the embryology and anatomy of the portal vein is of benefit in the understanding of these anomalies. Identifying deviations from normal portal architecture is important in the work-up for surgery such as liver transplantation, and prior to interventional procedures such as stent placement or embolization. The aim of this paper is to summarize the various types of congenital and acquired portal vein abnormalities that occur in children, describe their radiological features and provide images to demonstrate the differences from normal portal venous anatomy.

Abstract: Cisplatin-containing chemotherapy and complete surgical resection are both crucial in the cure of hepatoblastoma. Radical resection can be obtained either conventionally by partial hepatectomy or with orthotopic liver transplant, but the surgical approach to hepatoblastoma differs considerably across the world. Our main aim in this paper is to present the surgical recommendations of the Childhood Liver Tumour Strategy Group of the International Society of Paediatric Oncology (SIOPEL), as well as to stimulate international debate on this issue. We discuss biopsy, verification of resectability, resection principles, indications and potential contraindications for orthotopic liver transplant, as well as thoracic surgery for pulmonary metastases. We suggest that heroic liver resections with a high probability of leaving residual tumour should be avoided whenever possible. In such cases primary orthotopic liver transplant should be considered. Superior survival rates in hepatoblastoma patients who have received a primary transplant after a good response to chemotherapy support the strategy of avoiding partial hepatectomy in cases where radical resection appears difficult and doubtful. We recommend early referral to a transplant surgeon in cases of: (i) multifocal or large solitary PRETEXT IV (PRE Treatment EXTent of disease scoring system) hepatoblastoma involving all four sectors of the liver and (ii) unifocal, centrally located tumours involving main hilar structures or main hepatic veins. Because complete tumour resection is a prerequisite for cure, any strategy leading to an increased resection rate will result in improved survival. We advise the more frequent use of orthotopic liver transplant, as well as the standardisation of techniques for partial liver resection. These guidelines should not be seen as final, but rather as a starting point for further discussion between the various national and international liver tumour study groups. [Copyright &y& Elsevier]
