[Usefulness of computed tomography in determining risk of recurrence after a first episode of primary spontaneous pneumothorax: therapeutic implications].
The main cause of primary spontaneous pneumothorax is the rupture of subpleural blebs or bullae. The presence of bullae may also lead to an increased risk of recurrence. The best way to detect them is by means of computed tomography (CT). Our objective in the present study was to determine whether bullae detected by CT represent an increased risk of recurrence after a first episode of primary spontaneous pneumothorax. We also evaluated therapeutic implications. ⋯ The present study could not demonstrate that the presence, size, or number of bullae on CT scans has any influence on recurrence rate. We cannot recommend surgery after a first episode of primary spontaneous pneumothorax based on the presence of bullae on the CT scan.
