Interventional Radiology

interventional-radiology Interventional radiology (IR) involves the use of contemporary imaging techniques such as fluoroscopy (real time x-ray), with or without ultrasound, to place implants or guide the delivery of materials to specific areas inside the body for both diagnostic and therapeutic purposes. We can access blood vessels and various lumens (urethra, trachea, ureter, etc.) in order to deliver specific materials. IR is commonly used to treat many common ailments. At SVS, we offer treatment of congenital heart defects, implant pacemakers, place stents and coils, or even deliver medications directly into a tumor.

One example of this would be coronary artery stent placement, where a small metal mesh tube is placed within the lumen of the vessel in order to relieve a blockage during a heart attack. Within recent years, this modality has undergone tremendous evolution within veterinary medicine and new applications are constantly emerging.

Mainstream veterinary applications of IR currently available at SVS include:

  • Treatment of congenital heart defects (e.g. Patent Ductus Arterious/PDA, Pulmonic Stenosis)
  • Pacemaker implantation for bradyarrhythmias (e.g. complete heart block)
  • Tracheal stenting for collapsing trachea
  • Urethral stenting for palliative relief of malignant urethral obstructions (i.e. a tumor blocking outflow of urine from the bladder to the urethra)
  • Ureteral stenting for the management of obstructive ureterolithiasis (i.e. stones), stricture or malignancies

Additional less commonly employed applications of IR include the following:

  • Nasopharyngeal stenting for acquired or congenital strictures
  • Intra-hepatic shunt management
  • Embolization of inaccessible tumors using local chemotherapy
  • Ectopic ureter management
  • Nasojejunal feeding tube placement
