Methods: During seven years, from January 2012 until November 2019, data of eight patients who underwent posterior mediastinal mass resections for paraganglioma were collected and examined. Analysis of data was retrospectively processed and categorized as follows: demographics, preoperative, operative and postoperative.
Results: Among the eight patients, three presented with symptoms suggestive of functional paraganglioma (received preoperative preparations). Another two presented with non-functional posterior mediastinal mass, while the remaining three were removed during surgery (VATS) for other morbid conditions. Of these final three, two needed conversions after hemodynamic instability. Pathology suggested ?benign pathology? with an exception for one case. The outcome of our series was excellent without morbidity or mortality.
Conclusions: Proper preoperative investigations are needed to detect functional paraganglioma to perform optimal preoperative preparation and avoid a fatal intraoperative crisis. Tissue biopsy remains questionable, the need for embolization and bypass should be considered especially in aorticopulmonary types.
