What is Interventional Radiology?

Interventional Radiology (IR) is a medical specialty that performs minimally invasive, image-guided procedures to diagnose and treat diseases in nearly every organ system. Often called "surgery with a needle," IR represents a revolutionary approach that offers patients safer alternatives to traditional open surgery. 

Medicine's Third Pathway: Beyond Surgery and Medication

Unlike diagnostic radiology which focuses on interpreting images, IR physicians and technologists use real-time imaging technologies (like X-ray, ultrasound, CT, and MRI) to guide tiny instruments through blood vessels and other pathways to reach diseased areas—all through incisions no larger than a pinhole.

Minimally Invasive

Small incisions mean less pain and trauma to the body

Reduced Risk

Lower infection rates and fewer complications compared to open surgery

Faster Recovery

Many procedures are outpatient, with patients returning home the same day

Vascular Interventions:

  • Angioplasty & Stenting: Opening blocked arteries throughout the body

  • Embolization: Blocking blood vessels to stop bleeding or cut off tumors

  • Thrombolysis: Dissolving dangerous blood clots

  • Varicose Vein Treatment: Eliminating painful varicose veins without surgery

  • Thrombectomy: Mechanically remove dangerous blood clots with various devices
  • Intravascular Lithotripsy: Shockwaves fracture vascular calcium, helping balloons expand effectively

Drainage & Access:

  • Biopsies: Precise tissue sampling for diagnosis

  • Abscess Drainage: Removing infection without major surgery

  • Port Placement: Creating access for chemotherapy or dialysis

  • Feeding Tubes: Providing nutrition when swallowing is difficult

  • Hemodialysis catheter placement: Venous access for long-term dialysis treatment
  • Pleural/Abdominal catheter placement: Catheters inserted to manage and drain fluid

Oncology Services:

  • Chemoembolization: Delivering chemotherapy directly to liver tumors

  • Ablation: Using heat or cold to destroy tumors without surgery

  • Radioembolization: Targeting liver cancer with radiation-filled beads

Pain Management:

  • Nerve Blocks: Targeted pain relief for chronic conditions

  • Vertebroplasty: Stabilizing spinal fractures from osteoporosis

  • Kyphoplasty: Restoring vertebral height and stabilizing spinal fractures
