    Abstract:
    OBJECTIVE: This study was performed to explore the clinical features, typing, distribution, and treatment of pulmonary sequestration (PS), with the aim of improving the awareness and treatment of this condition. METHODS: Clinical data regarding surgical procedures, outcomes, and prognosis of 208 pediatric patients with PS who were treated in our center from January 2005 to October 2017 were retrospectively analyzed. RESULTS: PS was confirmed by ultrasonography, enhanced computed tomography (CT), and/or magnetic resonance imaging (MRI) before surgery, and the surgeries were smoothly performed in all 208 patients (138 males, 70 females; age, 1 month to 14 years; mean age, 19.70 ± 48.82 months). The operative time ranged from 10 to 230 min (mean, 70 ± 48.75 min), and the intraoperative blood loss volume ranged from 1 to 200 ml (mean, 5 ± 18 ml). PS was located in multiple sites of the thoracic cavity and was also found in some rare locations such as the neck and abdomen. The feeding arteries of the PS mainly arose from the thoracic aorta or abdominal aorta, and a few of them originated from other vessels in the systemic circulation. The venous drainage differed between intralobar and extralobar PS: in patients with intralobar PS, the venous drainage was mainly via the pulmonary veins, especially the lower pulmonary veins; in patients with extralobar PS, the venous drainage was via the azygos vein and hemiazygos vein or reached the right atrium via the vena cava. The infection rate in children with intralobar sequestration was 71.17% (79/111), and that in children with extralobar sequestration was 31.37% (16/51). CONCLUSION: PS has increasingly been detected by prenatal ultrasonography, and enhanced CT and MRI are the main techniques for diagnosing PS. Once confirmed, PS should be surgically resected. We choose an age of 6 to 12 months for surgical resection. Minimally invasive video-assisted thoracic surgery has many advantages in the treatment of PS and can be the treatment of choice for this condition. TYPE OF STUDY: Treatment Study. LEVEL OF EVIDENCE: Level III.
