Intra-articular osteoid osteomas are uncommon and occur in only 10-13% of cases. Intra-articular osteoid osteomas may not demonstrate typical clinical features and feature subtle radiographic differences when compared to extra-articular osteoid osteomas. Radiofrequency ablation (RFA) has been found to be a safe and reliable method of treating osteoid osteomas. The possible complications of RFA include bleeding, muscle burn, and in cases of intra-articular osteoid osteoma, septhic arthritis. In this study, we evaluated the efficacy of radiofrequency ablation (RFA) of intra-articular osteoid osteomas at a single tertiary pediatric center. Read More

Inguinal lymph node identification using ultrasound is critical in performing intranodal lymphangiography. We routinely utilize a 15 MHz “hockey stick” linear high resolution ultrasound probe (Philips Epic 7) for identification as well as to gain needle access into the inguinal lymph node. However in children with severe body wall edema and in low weight premature babied identification of lymph nodes can be difficult and sometimes impossible. Higher frequency ultrasound transducers offer the potential for improved identification of lymph nodes in such cases. The aim of this study was to compare imaging finding of high resolution US probe to the traditional 15 mHz probe in patients undergoing lymph node access for lymphangiography. Read More

Low dose C-arm Computed Tomography (CT), is a technology that uses flat panel detectors to acquire real-time 3D images during an interventional radiology (IR) procedure to assist with anatomic localization and procedural mapping. This study describes our low dose protocol and applications of its use at a pediatric institution. Read More

Percutaneous lymphatic interventions (PLI) target the pulmonary lymphatic abnormalities seen in patients with plastic bronchitis (PB). Existing data in patients with congenital heart disease(CHD)indicates poor transplant-free survival after the diagnosis of PB. We describe various techniques of PLI and characterize intermediate-term survival and complications after PLI. Read More
