Two patients died during the first 30 days (perioperative mortality) after pleural surgery for TETs (patients with TC suffered from pneumonia and acute respiratory distress syndrome after EPP; patient with TC undergoing total pleurectomy died due to acute pulmonary embolism and prolonged air leak). One patient with B2 thymoma undergoing EPP died between 30 and 90 days postoperatively (cause of death not tumour related). Two more patients died between 90 days and 1 year. A patient with TC after EPP died related to progression of metastatic disease at 8 months, and another patient with B2 thymoma after EPP died from pneumonia resulting in acute respiratory distress syndrome 10 months after surgery.
