Imaging of Vascular Anomalies.

Vascular anomalies (VAs) are a heterogeneous group of vascular malformations and tumors that are frequently encountered in daily practice. While most are benign, malignant vascular tumors exist, as do other nonvascular soft-tissue malignancies that may masquerade as a benign VA. The subtleties of arriving at an accurate diagnosis can be intimidating, as new entities are described and names of conditions have been modified.

What the Interventional Radiologist Needs to Know about the Genetics of Vascular Anomalies.

The purpose of this article is to familiarize the reader with the basic genetics and vascular biology behind the array of vascular anomalies they may encounter in their practice. Individuals with vascular malformations are often referred to multidisciplinary clinics composed of diverse specialists all with the same goal: how to provide the best care possible. The team is typically composed of physicians, nurses, social workers, and technical staff from multiple specialties including diagnostic and interventional radiology, dermatology, hematology/oncology, otolaryngology, plastic surgery, and several additional subspecialties.

Preoperative Multidisciplinary Team Huddle Improves Communication and Safety for Unscheduled Cesarean Deliveries: A System Redesign Using Improvement Science.

Background: Optimal communication between care teams is a critical component in providing safe, timely, and appropriate patient care. Labor and delivery (L&D) units experience rapidly changing clinical scenarios often requiring escalation in care and unplanned cesarean deliveries (CDs). The University of Cincinnati Medical Center (UCMC) is a 550-bed academic level 4 maternal care center with a 13-bed L&D unit in Cincinnati, OH.

Venous Compressive Disorders.

Venous compressive disorders are a heterogenous group of vascular syndromes characterized by extrinsic venous compression that can lead to complications of venous hypertension or venous thrombosis. Endovascular damage secondary to deep venous thrombosis (DVT) can result in post-thrombotic syndrome (PTS), a potentially debilitating condition that can be associated with significant morbidity in the pediatric population. Here we discuss 4 venous compressive disorders: iliac vein compression (May-Thurner syndrome [MTS]); subclavian vein compression at the venous thoracic inlet (Paget-Schroetter syndrome); left renal vein compression (nutcracker syndrome); and popliteal vein compression (popliteal entrapment syndrome) with a focus on clinical evaluation and diagnostic methods.

MS care: integrating advanced therapies and holistic management.

Lifestyle and environmental factors are key determinants in disease causality and progression in neurological conditions, including multiple sclerosis (MS). Lack of exercise, poor diet, tobacco smoking, excessive alcohol intake, social determinants of health, concomitant medications, poor sleep and comorbidities can exacerbate MS pathological processes by impacting brain health and depleting neurological reserves, resulting in more rapid disease worsening. In addition to using disease-modifying therapies to alter the disease course, therapeutic strategies in MS should aim to preserve as much neurological reserve as possible by promoting the adoption of a "brain-healthy" and "metabolically-healthy" lifestyle.

Fostering research in pediatric interventional radiology: needs assessment and suggestions for support.

Background: Due to the rarity of pediatric diseases, collaborative research is the key to maximizing the impact of research studies. A research needs assessment survey was created to support initiatives to foster pediatric interventional radiology research.

Objective: To assess the status of pediatric interventional radiology research, identify perceived barriers, obtain community input on areas of research/education/support, and create metrics for evaluating changes/responses to programmatic initiatives.

Sociodemographic Disparities in the Diagnostic Management of Pediatric Thyroid Nodules.

Importance: Thyroid cancer is the most common pediatric endocrine malignant neoplasm. Disparities in the workup of thyroid nodules may be significantly associated with thyroid cancer outcomes.

Objective: To determine the association of sociodemographic factors with the odds of receiving a biopsy, timeliness of the procedure, and risk of nodule malignancy.

Update on Pediatric Interventional Radiology.

The field of pediatric interventional radiology encompasses the treatment of a broad range of patients. Whether treating a premature infant who weighs less than 1 kg or treating an adult-sized teenager who weighs more than 100 kg, the innovative skills of the interventional radiologist are required to adapt equipment designed for adult patients, to meet the needs of children. Moreover, children cannot be treated simply as small adults owing to a number of factors, including differences in physiology, disease processes, and treatment techniques between pediatric and adult patients.

Kidney Replacement Therapy in Low Birth Weight Preterm Newborns.

Managing newborns with kidney failure is a complex undertaking; even under ideal circumstances, dialysis is technically challenging and available therapies are designed for adults. These issues are exacerbated in smaller newborns, and intervention has traditionally not been offered in those below a certain weight threshold. Ethical concerns abound and patients deemed too small for dialysis are typically transitioned to comfort or palliative care.

Pediatric trauma and the role of the interventional radiologist.

Purpose: While interventional radiologists occupy a critical role in adult trauma management, the role of interventionalist in pediatric trauma continues to evolve. The indications for transarterial embolization (TAE) are significantly different in pediatric patients in whom non-operative management (NOM) has a much more prominent role than in adults. Contrast extravasation on imaging may not require acute surgical or interventional management as it would in an adult.

Successful postoperative analgesia with ilio-inguinal nerve block following sclerotherapy for a labial venous malformation.

Though ilio-inguinal nerve block has been commonly utilised in male urologic surgery, a single injection ilio-inguinal nerve block alone has not previously been reported for analgesia of the vulva. In this report, we describe the case of a 14-year-old girl undergoing sclerotherapy of a venous malformation affecting the labia majora and minora. After induction of anaesthesia, we performed an ultrasound-guided ilio-inguinal nerve block using a total volume of 15 ml of ropivacaine 0.

Achieving Speaker Gender Equity at the SIR Annual Scientific Meeting: The Effect of Female Session Coordinators.

Purpose: To examine the impact of targeted efforts to increase the number of female speakers at the Society of Interventional Radiology (SIR) Annual Scientific Meeting (ASM) by reporting gender trends for invited faculty in 2017/2018 vs 2016.

Materials And Methods: Faculty rosters for the 2016, 2017, and 2018 SIR ASMs were stratified by gender to quantify female representation at plenary sessions, categorical courses, symposia, self-assessment modules, and "meet-the-expert" sessions. Keynote events, scientific abstract presentations, and award ceremonies were excluded.

Successful Medical Management of Life-threatening Hepatic Hemangioma in Neonates.

Hepatic hemangioma (HH) is a common asymptomatic, self-limiting benign vascular tumor of the liver in neonates. Although complicated HHs are rare, they have significant risks of morbidity and mortality, especially during the perinatal period. Because of the high risks of complications from surgical interventions, there is an unmet need for effective medical therapy.

Giant Congenital Melanocytic Nevus Treated With Trametinib.

Giant congenital nevi are melanocytic proliferations of the skin that may be complicated by melanoma, neurocutaneous melanocytosis, pain, pruritus, and disfigurement. Current treatment options include surgical resection and medical management of associated symptoms. There is limited efficacy in these modalities.

Untapped Resources: Attaining Equitable Representation for Women in IR.

Purpose: To investigate the current state of gender diversity among invited coordinators at the Society of Interventional Radiology (SIR) Annual Scientific Meeting and to compare the academic productivity of female interventional radiologists to that of invited male coordinators.

Materials And Methods: Faculty rosters for the SIR Annual Scientific Meetings from 2015 to 2017 were stratified by gender to quantify female representation among those asked to lead and coordinate podium sessions. To quantify academic productivity and merit, H-index, publications, and authorship by females over a 6-year period (2012-2017) were statistically compared to that of recurring male faculty.

Unleashing endogenous TNF-alpha as a cancer immunotherapeutic.

Tumor necrosis factor (TNF)-alpha was originally identified in the 1970s as the serum mediator of innate immunity capable of inducing hemorrhagic necrosis in tumors. Today, a wide spectrum of biological activities have been attributed to this molecule, and clinical translation has mainly occurred not in using it to treat cancer, but rather to inhibit its effects to treat autoimmunity. Clinical trials utilizing systemic TNF-alpha administration have resulted in an unacceptable level of toxicities, which blocked its development.
