INTRODUCTION: This study aimed to investigate the clinical characteristics and indicators of spontaneous hemopneumothorax (SHP) compared with primary spontaneous pneumothorax (PSP).
METHODS: We retrospectively evaluated patients who underwent surgery for spontaneous pneumothorax (SP) between April 2003 and April 2019. Clinical characteristics and perioperative outcomes were compared between SHP and PSP.
RESULTS: We identified 17 (8%) and 194 (92%) patients who underwent surgery for SHP and PSP, respectively. The SHP group was significantly older (mean±standard deviation: 31±10 vs. 25±8 years; p=0.002), with a higher proportion of patients aged >30 years compared to the PSP group (53% vs. 21%; p=0.006). Furthermore, the SHP group had definitive characteristics, left-side pneumothorax (82% vs. 54%; p=0.022), smoking habits (59% vs. 29%; p=0.009), and fewer patients with episodes of ipsilateral SP (12% vs. 50%; p=0.002) than the PSP group. In SHP, the most frequent bleeding point was the superior thoracic aperture in 15 patients (88%), followed by the left mediastinum in one patient. Seven patients (41%) of the SHP group had hemodynamic instabilities and needed perioperative blood transfusion.
CONCLUSION: SHP had distinct clinical characteristics compared to PSP. Older age (>30 years), left-side laterality, smoking status, and a first episode of pneumothorax were feasible indicators of SHP.
