Portal vein thrombosis (PVT) is a major cause of pediatric portal hypertension and gastrointestinal (GI) bleeding. Recanalization with balloon angioplasty (BA) and stent placement have emerged as a minimally invasive treatment option for PVT. We sought to review the success and complication rates of transcatheter PVT therapy in pediatric patients with native liver. Read More

Stenosis of the inferior vena cava or the hepatic veins is an underlying cause for hepatic compromise in liver transplant patients and in patients with inflammatory diseases of the liver, leading to considerable morbidity. CT-guided or ultrasound-guided minimally invasive vessel recanalization procedures can reverse liver failure in these patients by restoring vessel patency. However, it can be difficult to employ these techniques using traditional guidewire tips against fibrotic obstructions associated with vessels that have undergone repeated stenosis. Sharp recanalization offers an alternative strategy to gain access through these obstacles by utilizing needles or the sharp end of the guidewire tip to penetrate the vessel obstruction. This technique has been well-described and employed successfully in adult patients, but has not yet been reported in the pediatric setting. Read More

Bone biopsy for histopathology and tissue culture remains the gold standard for diagnosis of osteomyelitis. However, MRI often results in a radiologic diagnosis of osteomyelitis preceding biopsy. The purpose of this study is to examine the diagnostic yield of percutaneous bone biopsies and the effect of biopsy results on clinical management in children with suspected osteomyelitis and positive MRI findings.
