Risk analysis and outcomes of bronchopulmonary sequestrations

Researched and discussed the risks and outcomes of bronchopulmonary sequestrations, especially the intralobar type.

A retrospective review of our experiences with bronchopulmonary sequestrations from January 2012 to April 2015 is reported. The present study researched and discusses the risks and outcomes of bronchopulmonary sequestrations, especially the intralobar type, compared with other types of bronchopulmonary sequestrations in symptoms, surgery, pathology, and excretion.

A total of 126 bronchopulmonary sequestrations were diagnosed. All fetal chest cases (18–30 weeks) of solid or high-echo masses were diagnosed antenatally and then confirmed by ultrasound. Enhanced computed tomography was used to confirm the diagnosis. Eighty-three boys and 43 girls were included. The mean age at surgery was 4.2 ± 0.5 months. There were 103 cases of left, 22 cases of right, and 1 case of bilateral sequestration. There were 62 extralobar cases, 51 intralobar cases, 13 cases within the diaphragm, and a rare bilateral case. A preoperative history of recurrent respiratory tract infection was present in 39 cases, including 10 extralobar and 29 intralobar cases. Operations were completed successfully, and diagnoses were confirmed pathologically. Thirty-seven cases were associated with congenital bronchopulmonary malformation changes, of which 4 were extralobar, 31 were intralobar, and 2 were within the diaphragm.

The intralobar type was relatively uncommon among bronchopulmonary sequestrations. However, due to communication with normal lung tissue, infection is common in the intralobar type. Computed tomography examinations are very important immediately after birth. It is necessary to resect the mass in early childhood.
