Now, we are attending to the above-written meeting in Kobe and learning recent advantage of devices and techniques in the field of endovascular therapy. I could really enjoy a lot of talks about the situation of neurosurgery in Argentina and Japan with Prof. Pedro Lylyk from Department of Neurosurgery and Interventional Neuroradiology, Clinica La Sagrada Familia, Buenos Aires. We are going to meet again in Toyama and Buenos Aires in very near future.
