PURPOSE Studies of long-term percutaneous transluminal angioplasty (PTA) results have been less extensive in children than in adults. The authors sought to evaluate the outcomes of PTA for pediatric renovascular hypertension. MATERIALS AND METHODS The authors retrospectively evaluated 19 hypertensive children (ages 2-18 years) who underwent renal PTA from(More)
Fibromuscular dysplasia (FMD) and neurofibromatosis type 1 (NF1) are the most common causes of pediatric renal artery stenosis (RAS) in western countries, and characterization of their angiographic features could aid in an accurate diagnosis and in treatment. This study characterizes renal angiographic findings in pediatric fibromuscular dysplasia (FMD) and(More)
BACKGROUND Cystinosis is a metabolic disease characterized by accumulation of cystine in different organs and tissues, leading to potentially life-threatening organ dysfunction. Infantile cystinosis typically leads to end-stage renal disease, necessitating renal replacement therapy. Liver disease in cystinosis is rare and is mostly reported as nodular(More)
The purpose of this manuscript is to provide an overview of the normal development of the pancreas as well as pancreatic pathology in children. Diagnostic imaging plays a major role in the evaluation of the pancreas in infants and children. Familiarity with the range of normal appearance and the diseases that commonly affect this gland is important for the(More)
PURPOSE To evaluate the clinical outcomes of percutaneous sclerotherapy for congenital head and neck lymphatic malformations in our institution. MATERIALS AND METHODS Over a 7-year period, 17 children (10 M, 7 F) mean age 5.8 months (5 days to 13 months) underwent 49 sclerotherapy procedures for congenital head and neck malformations. The imaging and(More)
An infant, in whom the prenatal diagnosis of tuberous sclerosis complex was made, presented with extreme bilateral nephromegaly owing to diffuse cystic changes. Histology of the resected non-functioning left kidney revealed, in addition to the characteristic cysts, two foci of renal cell carcinoma not visible on US or MRI. This infant is exceptional given(More)
Historically, the evaluation of renovascular hypertension has been accomplished by US, renal scintigraphy and digital subtraction angiography. Based on its high accuracy reported in adults renal CT angiography (CTA) with pediatric-appropriate low radiation dose techniques has become an important tool in the workup of renovascular hypertension in children.(More)
The Mulliken and Glowacki classification (1982) differentiated vascular anomalies into two groups based on their endothelial characteristics: hemangiomas and vascular malformations. Vascular anomalies are localized defects of the vasculature that affect a limited number of vessels in a restricted area of the body. These defects are secondary to errors in(More)
Developmental dysplasia of the hip (DDH) includes a variety of states in the developing fetal, neonatal and infant hip. Initial pathology is the abnormal laxity of the hip joint making it susceptible to displacement of the femoral head from the acetabulum. Sustained subluxation or dislocation of the femoral head over time prevents normal development of the(More)
PURPOSE To report the outcome of tunneled dialysis catheter insertion in 120 patients. MATERIALS AND METHODS A retrospective review of the interventional radiology database and electronic medical records of 120 patients who had tunneled dialysis catheters inserted from April 1997 to July 2010 was performed with institutional review board approval. There(More)
