| Outline of Final Research Achievements |
We performed basic experiments and optimization of a novel therapy for venous malformation. In this therapy, heated saline, which has no systemic toxicity, is injected into the lesions and destroys vascular endothelial cells. In vitro experiments, maximum lethal temperature was 50 °C for both fibroblasts and vascular endothelial cells. Between 40 and 50 °C, however, fine adjustment of temperature led to death of only vascular endothelial cells and survival of fibroblasts. In vivo experiments, we used a rabbit model of venous malformation with auricular vein. Our results indicate that injecting heated saline is a potential therapy for venous malformation.
