Interventional Radiology

Interventional radiology is available at our Cherry Hill, Edmonds, First Hill and Issaquah facilities. The departments feature several procedure rooms, and specially trained physicians utilize many non-surgical, minimally invasive treatments as alternatives to open surgical procedures. Interventional radiology procedures are generally easier for the patient because they involve small incisions, minimal pain and shorter recovery times.

Our interventional radiologists are board certified physicians with additional advanced training in minimally invasive, targeted treatments performed using imaging to guide them. They use their expertise in X-rays, CT, ultrasound and other medical imaging technologies to guide small instruments such as catheter tubes through the blood vessels or other pathways. Diseases are treated through the skin versus through open surgery.

Possible complications

Most interventional radiology procedures are performed using an IV sedative to help you relax. After the procedure, you may have some discomfort in the area of the body where the procedure was performed.

What to expect prior to your exam

Most procedures will require a lab and discontinuance of blood thinning medications prior to your procedure. Your doctor will explain this to you and an interventional nurse will contact you the day prior to your procedure regarding pre-procedure instructions.

Please do not eat or drink anything past midnight the night before your procedure, unless you are otherwise instructed in the pre-op phone call. This includes gum, mints and water.

What to expect the day of your exam

  • Please bathe or shower the morning of your procedure.
  • You are required to have an escort drive you home after your procedure. Escorts of minors must remain on site while the patient is in our care.
  • Things to bring with you: photo ID, insurance/pharmacy cards, medication list with dosages, allergy list with reactions
  • Leave all your valuables and jewelry at home.
  • A receptionist will register you and ask you to sign a hospital consent form.

  • You will change into a hospital gown.
