The results and outcome of primary spontaneous pneumothorax in adolescents

Primary spontaneous pneumothorax (PSP) is a rare pulmonary pathology that occurs in the absence of known lung disease. A retrospective study was performed to evaluate the results and outcome of PSP treatment in adolescents.

The cases with PSP from January 2004 to December 2017 were evaluated for age, sex, family and smoking history, clinical and radiological findings and results of treatment.

Ten cases with PSP were included. The mean age of the patients was 15 years (10-17 years) and the male to female ratio was 9:1. Two of the patients (20%) had family history of PSP and four cases (40%) had smoking history. The initial complaints were chest pain (n=8), acute onset of cough (n=1) and breathing difficulty (n=1). Tube thoracostomy was performed in nine cases in which three of them were bilateral. Chest computed tomography (CT) demonstrated bullae (n=4; 40%) and subpleural blebs (n=2; 20%). Pleurodesis with talc was performed in four patients with pneumothorax for longer than a week in follow-up (n=4; 40%). Five cases had recurrent PSP within one year (n=5; 50%) and underwent pleurodesis with talc (n=4), autologous-blood (n=1) and bleomycin (n=1). Bleb excision was performed in two cases with persistent pneumothorax despite pleurodesis.

Tube thoracostomy and oxygen supplementation, are considered as initial and adequate treatment of PSP in most of the adolescents. Prolonged air leaks require pleurosdesis as the first line treatment and surgical excision of blebs should be reversed for the patients who are unresponsive to other treatment options.
