Finite element analysis for severe asthma therapy at the airway smooth muscle by radiofrequency ablation

摘要

This paper presents a three-dimensional finite element analysis for severe asthma therapy by using radiofrequency (RF) ablation. We study a solution for severe asthma treatment by using radiofrequency ablation method. Severe asthma patients have breathlessness symptom, coughing, and wheezing that influence a daily life of patients. In case of severe asthma, patients have breathlessness symptom, coughing, and wheezing all the time. All symptoms cause to die. Severe asthma therapy by using radiofrequency ablation is a new alternative maneuver to the patient and hopefully may extend his lifetime, reduce using of medicines in asthma treatment and also save money on medical care in long run. The research results obtained from our three-dimensional finite element analysis show temperature distribution for airway dilation and increasing airway wall dimension by using radiofrequency ablation technique significantly. These results also guide us to develop an advance asthma treatment in the future.
