Microwave Ablation of Metastatic Lung Lesions Under Guidance of Augmented Reality CT Navigation System (Sirio): A Case Report

Abstract

Microwave ablation (MWA) of lung lesions under guidance of computed tomography (CT) and SIRIO system (Sistema robotizzato assistito per il puntamento intraoperatorio) is providing accurate and real time visualization system. We present a case of 65 y male patient with multiple metastatic lung lesions from gluteal mesenchymal tumor confirmed histopathologically, MWA of two lesions under general anesthesia using double lumen endotracheal tube to exclude LT lung. Complete ablation of lesions was achieved, post-procedure pneumothorax was treated by (Heimlich valve) insertion, 24 hours follow up revealed complete resolution of pneumothorax. In this case report we found that the total procedure time and the total effective radiation dose of the whole procedure were reduced in compared with a previous case of MW ablation of similar sizes lesions under CT guidance only.
