目的探讨多层螺旋CT及后处理技术显示肺隔离症异常血管的价值.方法回顾性分析10例经手术和病理证实的肺隔离症患者的胸部CT平扫、增强及最大密度投影、多平面重组、容积再现等重建图像. 结果 9例为肺叶内型,1例为肺叶外型;8例位于左下肺,2例位于右下肺;血管重建可显示9例异常供血血管(其中7例来自降主动脉,2例来自腹主动脉),并清楚显示其起源、走行、分支和分布,除1例引流至奇静脉外,其余均引流至下肺静脉. 结论多层螺旋CT血管成像及其后处理重建技术能很好地显示肺隔离症的异常血管,对肺隔离症的诊断具有重要的临床应用价值,可作为该病的首选检查方法.

Objective To assess the value of MSCT and postprocessing techniques in displaying abnormal blood vessels of pulmonary sequestration. Methods Ten patients with pulmonary sequestration proved with operation and pathology underwent both plain and enhanced chest CT scan. The reconstructed images of maximum intensity projection, multiplanar reconstruction and volume rendering were analyzed retrospectively. Results Of 10 patients, intra-lobe type sequestration was seen in 9 patients and extra-lobar type in 1 patient. The lesions located in the left lower lobe in 8 patients and in the right lower lobe in 2 patients. Angiography postprocessing technique displayed abnormal supplying vessels in 9 patients (7 from descending aorta and 2 from abdominal aorta) and displayed the origin, courser, branches and distribution of lesions clearly. Vessels in 9 patients drained into inferior pulmonary veins except in one drained into azygos vein. Conclusion MSCT angiography with postprocessing reconstruction techniques can display abnormalities of pulmonary sequestration clearly and has great value in the diagnosis of pulmonary sequestration, so as might be the first choice in diagnosing pulmonary sequestration.
