Interventional Radiology

Interventional Radiology is used to diagnose and treat diseases through the use of catheters and advanced imaging, in many cases eliminating the need for risky surgeries and lengthy recoveries.

The Interventional Radiology team at VSH – North County is organized to provide comprehensive care in every facet of minimally invasive procedures. Interventional radiology is performed using state of the art diagnostic and therapeutic modalities to perform procedures on various body systems with the use of small catheters inserted into the arteries, veins, or other hollow organs within the body.

Imaging modalities include fluoroscopy, endoscopy, computed tomography (CT), ultrasonography, and MRI. Through the use of advanced imaging, these procedures are able to treat several disorders while minimizing pain, recovery time, complications, and long term side effects commonly seen with more invasive surgical procedures.

Our team is one of a few across the nation that can perform the vast procedures described below. Many of these procedures are performed through teamwork with our colleagues in the Surgery, Internal Medicine, and Radiology Services.

Minimally Invasive Procedures

The interventional radiology team uses minimally invasive procedures and dedicated medical equipment to treat the following conditions and diseases in dogs and cats:

Image guided, percutaneous interventions in the chest, abdomen, and extremities can be used to treat the conditions below. This represents a detailed, but incomplete list. The Interventional Radiology service accepts requests for client consultations and phone consultations with referring veterinarians. If you are interested in a procedure that is not on the list below, please contact us.
