28例肺隔离症的临床分析

目的探讨肺隔离症的病因、诊断、鉴别诊断及治疗方法。方法回顾性分析28例手术证实为肺隔离症的临床资料并复习相关文献。结果 1998年至今该院收治的28例肺隔离症,其中叶内型26例(92.9%),叶外型2例(7.1%)。叶内型多以咳嗽、脓痰、咯血和发热等呼吸道感染症状为主,叶外型多无症状,但部分伴其他畸形。术前确诊该症6例(21.5%),主要诊断方法为胸片、CT、MRA、选择性动脉造影。全组均为肺叶切除,无手术死亡及并发症发生。结论肺隔离症发病率低,易误诊及漏诊,诊断方法主要为X线、CT、MRI检查及主动脉逆行造影等检查方法,发现异常的主动脉供血血管是明确诊断的关键。

Pulmonary sequestration:a clinical analysis of 28 cases

Objective To explore the pathogen, diagnosis and treatment of pulmonary sequestration. Methods Data of twenty-eight patients with pulmonary sequestration were retrespectively analyzed and the literatures were reviewed. Results 26 cases（92.9% ）were intralobar type,2cases （7.1%） extralobar type. Most of the 26 cases had respiratory infection,6 eases had no symptoms. 6 eases（21.5% ） were confirmed before operation by X-ray, CT, MRI and angiography. Lobectomy was performed on every case and there was no post-operative morbidity. Conclusion X-ray, CT, MRI are useful for the diagnosis. Finding the anomalous systemic artery is the key in diagnosis of pulmonary sequestration.
