Veterinary Interventional Radiology

Interventional radiology involves the use of contemporary imaging methods (primarily video x-ray, called fluoroscopy) to gain access to different structures of the pet's body for diagnostic and therapeutic reasons without the need for traditional surgery.

Veterinary Interventional Endoscopy

Interventional endoscopy involves the use of endoscopes, small cameras which can be guided throughout the body via naturally existing orifices, often in conjunction with other contemporary imaging techniques, such as ultrasound or fluoroscopy. Guided by these images, the veterinarian can reach most parts of the body without the need for open surgery.

These non-surgical alternatives offer many advantages, including:

  • Quicker recovery
  • Less anesthesia time
  • Shorter hospital stay
  • Less pain

Examples of health issues treated interventionally:


  • Nasopharyngeal stenting
  • Tracheal stenting
  • Tracheal balloon dilation

  • Fluoroscopic-assisted tracheobronchial foreign body removal
  • CT-Guided lung biopsy


  • Esophageal balloon dilation
  • Esophageal stenting
  • PEG: Percutaneous endoscopically-placed gastric tubes
  • Jejunostomy through PEG tube
  • Colonic stenting
  • Laser ablation of colonic polyps
  • Anorectal balloon dilation


  • Hepatic vascular stenting (for vascular obstruction secondary to tumors)
  • Percutaneous transjugular coil embolization for PSS
