Abstract

Abstract:

The treatment of mediastinal tumor has always been a clinical difficulty due to its complex anatomical location and many important organs. Compared with traditional local treatment, endobronchial ultrasound guided laser multi-point ablation of mediastinal tumors has many advantages, including real-time monitoring of ablation range and effect, avoidance of damage to normal tissue and organs, few side effects and good tolerance. This article describes the standard operating procedure for endobronchial ultrasound guided laser multi-point ablation of mediastinal tumors.

Key words: catheter ablation, bronchoscopes, mediastinal neoplasms, endobronchial ultrasound guided laser ablation

Figures/Tables 6

Fig.1 The EBUS field of view showing ablation fiber tends to emit energy forward

Fig.2 An obvious coking cavity appeared in the ablation center，forming a blind spot in the EBUS ultrasound field of view

Fig.3 The EBUS field of view showed that the fiber endpoint was close to the blood vessel

Fig.4 EBUS monitoring of energy distribution and new hyperechoic areas during ablation

Fig.5 Adjusted the lens body and EBUS field of view so that the fiber endpoint was in the middle of the EBUS field of view

Fig.6 After multi-point laser ablation，two new hyperechoic ablation centers could be seen in the EBUS field of view
