| Outline of Final Research Achievements |
We created the HIFU treatment device that located the probe for the image in the center of HIFU transducer newly, furthermore, we introduced a degassed cooling circulation device in a treatment system. Sequential HIFU irradiation contains a trigger wave, heating wave and rest time. We confirmed that both artery and vein could occlude by the animal experiment using the rabbit histologically. The ultrasonic irradiation sequence used in the present study allowed confirmation of ultrasound images even during HIFU irradiation. Targeting could be achieved by setting the imaging probe in the center and placing the HIFU beam and imaging ultrasonic wave on the same axis. We performed the HIFU treatment for 2 cases of TRAP sequence and succeeded in occlusion of intraacardiac fetal blood flow. However, reperfusion were observed. Radio frequency ablation was added sequentially and was able to be treated.
