The role of transarterial embolization has been well studied in adults but data is lacking in the pediatric population. As a newly designated level 1 trauma center we present our institutional experience of the efficacy and safety of transarterial embolization for pediatric abdominal and pelvic trauma as well as a review of the current literature. We discuss the multidisciplinary approach to management and the role of the interventionalist as a clinician. Read More

Hemangioma occurs mainly in soft tissue but rarely be shown in bone. It is benign vascular bone tumors that account for 1% of all primary bone tumors. It is also called hamartoma because it is proliferating tumor originated from bone tissue. Most prevalent sites of intraosseous hemangioma are vertebrae and skull. Within the calvarium, the parietal bone is most commonly involved followed by the frontal bone. Within the facial skeleton, the mandible, maxilla, and nasal bones are involved. Hemangioma of the maxilla is very rare in newborn period. We experienced a neonatal case of intraosseous hemangioma of the right maxilla treated with embolization in an early infant period.

In 2014, 3 patients including a 28-week preemie, 18 day-old neonate, and 11 month-old infant, were treated for large hepatic AVMs. Symptoms included CHF in both the 890-gram preemie and neonate and no symptoms in the infant with imaging revealing extensive shunting. Embolization of the AVMs was performed using various agents, entry sites, and arterial and venous techniques. Agents utilized included detachable and non-detachable coils and vascular plugs. Both direct puncture and intra-vascular techniques, including the use of the umbilical artery, were utilized. Immediate hospital course and short-term clinical and radiographic follow-up was conducted.

Technical success was achieved in all 3 patients without immediate complications. The two symptomatic patients improved clinically on short-term follow up with resolution of the preemie’s and neonate’s CHF, confirmed on post-embolization imaging. Conventional angiography demonstrated complete resolution of the AVM in the infant. Read More

Congenital portosystemic shunt is a rare vascular malformation that leads to severe complications. Two types are described: extrahepatic and intrahepatic. Extrahepatic shunt is represented by a direct communication of the portal trunk, or one of its branches of origin, to the inferior vena cava, or one of its branches.

We present two cases of extrahepatic shunt treated with stent-graft placement.

Case 1: Two y.o. male with cutaneous telangiectasias and liver calcifications on abdominal ultrasound. An extrahepatic portosystemic shunt was detected on color Doppler examination.

MR and catheter angiography revealed a large fistula between the main portal vein and the suprarenal inferior vena cava. The fistula was closed by deploying a balloon expandable stent-graft in the retrohepatic inferior vena cava. Five years later, the liver function was normalized and no complication was observed.

Case 2: Thirteen y.o. male referred for three hepatic lesions and an extrahepatic portosystemic shunt.

MR and angiography revealed a large fistula between the left portal vein and the inferior vena cava. It was closed by deploying a custom self-expandable stent-graft (Zenith, Cook Medical, Bloomington, IN) in the inferior vena cava. At five years follow-up, the patient is asymptomatic with a resolution of the liver lesions. Read More

Vascular malformations in pediatric populations range from simple venous malformations to complex arteriovenous malformations. These present a spectrum of clinical and imaging findings. As radiologists, understanding these vascular anomalies is crucial for accurate diagnosis and determining appropriate therapeutic strategies. This educational exhibit aims to provide a comprehensive review of pediatric vascular malformations, enriched with insights from clinical cases. Read More

Ultrasound guided percutaneous liver biopsy is frequently performed in pediatric patients. Published post-biopsy complication rates range between 0.3 - 3.3% according to Society of Interventional Radiology Standards of Practice. Post-biopsy tract embolization has been prophylactically used to theoretically decrease the bleeding risk, but is not the current standard of care at our institution. The goal of this study is to determine if there is a need for prophylactic biopsy tract-embolization after ultrasound guided liver biopsy in the pediatric population.
