The predictive value of the Haller index for recurrent pneumothorax risk after primary spontaneous pneumothorax

In this study, we aimed to evaluate the predictive value of the Haller index for recurrence risk in primary spontaneous pneumothorax patients. Between January 2018 and December 2023, a total of 285 patients (260 males, 25 females; median age: 23 years; range, 17 to 35 years) with primary spontaneous pneumothorax who underwent thoracic computed tomography and followed for at least one year were retrospectively analyzed. The patients were divided into two groups as the non-recurrence group (n=170) and recurrence (n=115) group. The Haller index was calculated from computed tomography scans at presentation and its predictive value for recurrent pneumothorax was estimated. The median age was significantly higher in the non-recurrence group than in the recurrence group (p
