Abstract:
Total 2625 cases of pulmonary sequestration were collected from literatures of Chinese National Knowledge Infrastructure from 1998 to 2008. The age, gender, clinical symptoms, chest CT scan,chest X-ray findings, lesion location, supplying artery, venous reflux, and preoperative misdiagnosis of 2625 cases were retrospectively reviewed. The male: female ratio of all cases was 1.58: 1. The main clinical symptoms of pulmonary sequestration were cough, sputum, fever, hemoptysis and chest pain, but 13.36% patients were asymptomatic. Chest CT scan showed pulmonary massive lesions (49.00%), pulmonary cystic lesions (28.57%), pulmonary cystic-solid lesions ( 11.57% ), and flaky shadows (7.96%). Pulmonary sequestration mainly located in the lower lobe; 66. 43% located in the left posterior basal segments, and 20. 16% located in the right posterior basal segments. Pulmonary sequestrations were divided into three types, intralobar sequestration (83. 84% ), extralobar sequestration ( 16.03% ), and mixed sequestration (0.13% ). The arterial supply was mainly from branches of thoracic aorta (76. 55% ) and abdominal aorta (18.47%). The clinical manifestations of pulmonary sequestration were various, so the preoperative misdiagnosis rate was as high as (59 ± 20) %. We should take full advantage of clinical symptoms, imaging findings and location characteristics to improve the preoperative diagnosis rate.
