Dr. Okuno was invited and had two talks on OEIS in Las Vegas. 

The 9th Outpatient Endovascular and International Society（OEIS）was held from June 24-25, 2022 at Las Vegas. Our director Dr. Yuji Okuno was invited and had speeches at the conference with the theme of Embolization for Chronic Shoulder, Knee, and Other Joint’s Pain: How we do it, and another talk for dinner symposium. 

After each talk, many doctors from the States questioned him. It was also an opportunity to realize that catheterization for chronic pain is of strong interest in the United States as well.
