Outline of Research at the Start

光ファイバを血管内目的部位まで到達させたカテーテルを介して進めて、血管内焼灼により血管閉塞が可能であることを生体ブタを用いた動物実験で検証する。動脈閉塞に関しては血管撮影による動脈像、病理学的評価により検討を行う。あわせて、血管内焼灼において最適なパラメータ(出力、時間など)も評価する。

Outline of Final Research Achievements

In this study, we investigated the feasibility of arterial occlusion through intravascular ablation using a "Fiber Optic Therapy Device" via basic and animal experiments with live pigs. In the animal experiments, successful occlusion of the renal arteries was confirmed through both angiographic imaging and histological analysis. Additionally, we found that the temperature rise was significantly suppressed in a perfused environment with active blood flow, and that ablation tended to be more effective in curved vessel segments compared to straight ones. We also observed a characteristic temperature pattern during arterial occlusion, marked by a rapid temperature spike. Furthermore, excessive ablation was found to cause vascular collapse and contrast agent leakage. These findings contribute to the development of safe and effective methods for vascular cauterization and embolization.

Academic Significance and Societal Importance of the Research Achievements

本研究は、高出力半導体レーザを応用した「光ファイバ治療器」による血管内焼灼という、従来の物理的塞栓とは全く異なる新しい作用機序に基づく動脈塞栓術の実現可能性を、実験的に世界で初めて明らかにした点で極めて学術的意義が高い。リアルタイム温度モニタリングによる制御で動脈内の標的部位のみを選択的に加熱・閉塞できる本技術は、高価な塞栓物質を使用せず安全かつ確実な塞栓を可能とし、塞栓治療の在り方に革新をもたらす可能性を秘めている。今後、出血制御や腫瘍塞栓への臨床応用が進めば、医療費削減、資源節約、患者負担軽減に加え、医療格差の是正や低リソース地域での応用も期待され、社会的意義も極めて大きい。
