To investigate the diagnosis of pulmonary sequestration, and compare the therapeutic effects between open chest surgery and thoracoscopic surgery for pulmonary sequestration.

The clinical data of 18 patients with pulmonary sequestration undergoing surgical treatments in Tianjin Medical University General Hospital between October 2009 and January 2016 were retrospectively analyzed, including 7 cases of thoracoscopic surgery and 11 cases of open surgery. The mean age, operation time, volume of intraoperative blood loss, time of postoperative drainage, volume of postoperative drainage, occurrence of postoperative complications, postoperative hospitalization time and total hospitalization expenses were compared between two groups.

The mean time of postoperative drainage and hospitalization in thoracoscopic surgery group was significantly shorter than that in open chest surgery group(t=4.553, P<0.05; t=5.068, P<0.05). However, there was no significant difference in mean age, operation time, volume of intraoperative blood loss and total hospitalization expenses between two groups(P>0.05). The diagnosis was mainly based on chest imaging diagnosis, especially chest enhanced CT and three-dimensional reconstruction of blood vessel imaging, which revealed abnormal arteries. In particular, multi-slice spiral CT scan significantly reduced the artifacts of three-dimensional reconstruction, which made the image closer to reality. Then, the preliminary diagnosis was formed on the basis of previous disease history.

Thoracoscopic surgery is safe and reliable to treat pulmonary sequestration with thoracoscopic surgery, which is worthy of widely application.
