Clinical Study on the Effects of Pulmonary Vessels on Cryoablation and Preventive Embolization Strategies

Sponsor: Haibo Shao

Summary

This study targeted high-risk individuals with incomplete ablation and performed selective pulmonary artery embolization before lung cryoablation, which could enhance the therapeutic effect and reduce the risk of intraoperative bleeding. Previous studies have shown that selective pulmonary artery embolization before ablation has no adverse reactions related to embolization. In this study, gelatin sponge particles were used for selective pulmonary artery embolization. Gelatin sponge is an absorbable embolic material that can be absorbed and degraded in the human body within about 7 days, which has high safety and a low probability of adverse reactions. The surgical risks are detailed in the surgical protocol. The study aims to optimize the lung cryoablation strategy for high-risk individuals with incomplete ablation, aiming to improve the prognosis of high-risk recurrent patients. The two groups of patients underwent lung CT reexamination every three months after surgery to observe the tumor ablation situation.

Official title: This Study Aims to Provide New Evidence for Optimizing the Lung Cryoablation Strategy by Targeting High-risk Individuals With Incomplete Ice Ball Morphology in Lung Cryoablation. This is Achieved Through the Use of Selective Pulmonary Artery Embolization.
