Two case reports of preoperative selective artery embolization with robotic-assisted thoracoscopic lobectomy for chronic cavitary pulmonary aspergillosis: technology, safety and short-term outcomes.

Background: Minimally invasive surgical resection is a possible radical treatment for pulmonary aspergillosis; however, it is difficult and can be accompanied by a variety of complications, especially in chronic cavitary pulmonary aspergillosis (CCPA). Selective artery embolization is usually conducted as palliative management or emergent control of hemoptysis in CCPA. In this report, we share our experience of 2 CCPA patients who underwent preoperative selective artery embolization followed by robotic-assisted thoracoscopic lobectomy. Case Description: Two male patients with post-tuberculosis CCPA had recurrent hemoptysis. They underwent preoperative selective artery embolization and robotic-assisted thoracoscopic lobectomy in July-August 2022. The intraoperative blood loss volumes for the 2 patients were 160 and 200 mL, respectively. Both patients had good short-term outcomes, and the post-operative stays for each patient were 15 and 9 days, respectively. Conclusions: Robotic-assisted thoracoscopic lobectomy following selective artery embolization is a potential safe and effective treatment for CCPA. Robotic resection has a number of advantages, including the dexterity, the sharp, 3-dimensional, and magnified vision, and a minimally invasive procedure. Selective preoperative feeding artery embolization can reduce intraoperative bleeding and provide a clearer surgical vision, thus facilitating minimally invasive approaches. We expect further systematic clinical researches to validate the conclusion.
