Interventional Radiology

Interventional radiology uses image-guided procedures (X-rays, fluoroscopy, ultrasound, and CT) to diagnose and treat diseases throughout the body. Many of these procedures require minimally-invasive technics using a small needle, which minimize the risk and improve recovery time in comparison to traditional open surgery.

Services We Offer

  • Aneurysmal Bone Cysts: Radiology physicians at Nationwide Children’s Hospital were the first to discover and pioneer the minimally-invasive treatment of aneurysmal bone cyst using doxycycline foam injections. Our team pioneered the precise use of ultrasound as a highly specific imaging tool for identification of solid tumor nodules in the aneurysmal bone cysts, which allows for precise, minimally-invasive treatment of all parts of the tumor.
  • Dermoid Ablations: Nationwide Children's Hospital is considered the expert in dermoid cyst ablation treatment because of the non-surgical, minimally-invasive procedure that was developed and pioneered by our interventional radiology team.
  • Salivary Gland Ablations: Prior to advancements at Nationwide Children’s Hospital, there were no successful interventional radiological (minimally invasive) therapies for ranulas. Ranula is a condition when saliva cannot get into the mouth and builds up into large bubbles (cysts) either in the floor of the mouth or in the neck. The need for salivary gland ablation treatment was recognized, so our interventional radiologists developed a new procedure. Patients with both simple ranulas and plunging (dividing) ranulas have been successfully treated without surgery for 10 years at Nationwide Children's Hospital. We have treated kids and adults in ages ranging from 5 to 54 years.
  • Lymphatic Malformations: Interventional radiologists at Nationwide Children’s Hospital have created an internationally-recognized program for providing innovative, successful minimally-invasive treatment of lymphatic malformations. For more than 20 years, our radiology team has been refining the treatment process, especially in the eye, abdomen, head and neck. Our team truly is the lymphatic malformation expert because they have developed and perfected the following procedures:
    • A dual-drug catheter based treatment of macrocystic (large) lymphatic malformation, which is a technique using a new coaxial catheter system to access the eye, head, neck and the extremities.
    • The first, successful minimally-invasive "foam" injection treatment for microcystic (small) lymphatic malformation, which was long considered to be untreatable using traditional injection treatments.
    • A microcystic venolymphatic malformation (both lymphatic vessels and veins) treatment using another foam injection with a drug called "bleomycin."
    • An outpatient macrocystic lymphatic malformation treatment with a novel dual-drug system.
  • Orbital Slow Flow Malformations
  • Venous Malformations
  • Sclerotherapy
    • Branchial Cleft Cysts and Sinuses
    • Thyroglossal Duct Cysts
    • Organ cysts
    • Solid benign tumor ablations
