Interventional Radiology

Mount Sinai South Nassau Interventional Radiology

What is Interventional Radiology?

Interventional Radiology is a sub-specialty of radiology that uses image guidance to perform minimally invasive procedures. Interventional radiologists (board-certified physicians) use tiny instruments, including catheters and wires to diagnose and treat a variety of conditions and diseases that once required open surgery. Image guided therapy eliminates the need for open surgery and allow shorter recovery times and hospital stays. Under the leadership of Sydney Yoon, MD, interventional radiology at Mount Sinai South Nassau continues to advance in this rapidly growing field of medicine.

Benefits of Interventional Radiology

  • Most procedures can be performed as an outpatient or require only an overnight stay
  • Most procedures are performed with local anesthesia, seldomly with general anesthesia
  • Many vascular procedures can be performed from the wrist, including uterine artery embolizations

  • Liver, kidney and lung cancer
  • Uterine fibroids
  • Vertebral compression fractures
  • Pulmonary emboli/DVT
  • Filter placement and removal
  • Varicose veins
  • Poor venous access (ports, PICCs, tunneled catheters)
  • Gastrointestinal bleeding
  • Musculoskeletal pain
  • Abscess
  • Biopsy
  • Gallbladder disease
