NCT ID NCT06128681
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new ultrasound-guided technique to diagnose and treat mediastinal diseases (conditions in the chest area). Researchers will compare this method to traditional approaches in 30 participants. The goal is to see if the new technique improves diagnostic accuracy and helps treat mediastinal masses using freezing or laser.

Who is studied
The patient had mediastinal imaging abnormalities, and the disease type could not be identified through routine examination, and it was difficult to carry out further treatment or the patient was not satisfied with the previous treatment effect; In addition, patients with clearly diagnosed malignant tumors are difficult to perform tumor resection, or patients with other reasons are difficult to tolerate surgical open surgery, and mediastinal tumor ablation can reduce tumor compression and achieve the purpose of tumor reduction
