IVR (Interventional Radiology)

IVR means a series of treatments using various tools (catheter, puncture needle, etc.) inserted percutaneously into a body cavity while observing the inside of the body by diagnostic imaging, such as radiography, angiography, ultrasonography or CT. Catheterization is one method used in IVR. Hokkaido University Hospital is an institution designated by Japanese Society of Interventional Radiology, and our radiologists, mostly specialists affiliated to the Society, are providing IVR in cooperation with many departments. Examples of diverse IVR applications are given below. If you are interested in IVR, consult your doctor and make an IVR reservation for your first visit to the Department of Diagnostic and Interventional Radiology.

  • IVR of hepatocellular carcinoma/liver metastases (arterial embolization/chemoembolization/trans-arterial chemotherapy)
  • Arterial embolization of visceral artery aneurysm (liver, spleen, pancreas, kidney, etc.)
  • IVR of traumatic bleeding/iatrogenic bleeding/hemoptysis (arterial embolization, stent graft insertion)
