Interventional Radiology

Interventional Radiology

Interventional Radiology is a sub-specialty of radiology that uses image guidance to perform minimally invasive procedures. Board-certified interventional radiologists use tiny instruments, including catheters and wires to diagnose and treat a variety of conditions and diseases that once required open surgery. By minimizing the physical trauma to the patient, non-surgical interventions reduce recovery time and hospital stays.

Some of the interventional treatments that are used at South Nassau include:

  • Uterine Fibroid Embolization – a minimally invasive technique used to shrink painful uterine fibroids that can affect women 35 and older
  • Y-90 Radioembolization treats liver tumors
  • Bland Embolization – Non-chemotherapeutic embolization involving the injection of small particles through a catheter in the hepatic artery. It is performed to block – or reduce the blood flow to cancer cells in the liver
  • Thermal Ablation – Uses microwave and/or radiofrequency energy to destroy tissue by heating it. The procedure is used in the treatment of renal cell cancer, liver cancer and lung cancer.

Interventional Radiology is also used to help guide in the placement of certain devices, via Vascular Access, which may include the following procedures:

  • Ports and tunneled catheters
  • Peripherally inserted central catheters (PICCs)
  • Transjugular intrahepatic portosystemic shunts (TIPS)
  • Gastric and esophageal variceal embolization, and more.
