37例肺隔离症的诊断和治疗分析

目的探讨肺隔离症的诊断、鉴别诊断和治疗方法。方法回顾性分析37例手术证实为肺隔离症的临床资料并复习相关文献。结果1985年至今该院共治疗37例肺隔离症，其中叶内型33例（89%），叶外型4例（11％）。叶内型以咳嗽、脓痰、咯血和发热等呼吸道感染症状为主，叶外型多无症状。术前确诊该症10例（27％），主要诊断手段为胸片、CT、MRA、选择性动脉造影。两例患者施行了PET检查。该组均为肺叶切除，无手术死亡及并发症发生。结论肺隔离症发病率低，临床表现不特异，易误诊和遗漏。诊断方法和技术在不断提高，异常的主动脉供血血管是肺隔离症诊断的关键。手术是该症目前的治疗方法。

Pulmonary sequestration: review of 37 cases

[Objective] To explore the cause,diagnosis and treatment of pulmonary sequestration.[Method] 37 cases were analyzed and literatures were reviewed.[Result] Between 1985 and now,37 cases(89 %)were intralobar type,4 cases(11%)were extralobar type.Most of the 33 cases accompanied with respiratory infections,the 4 cases had no symptoms.10 cases(13%)were confirmed before operation by CT,MRI and angiography.Lobectomy was performed in every case,no post operative morbidity happened.[Conclusion] Despiteitsrarity,X-ray,CT,MRI and angiography are sufficiently suggestive of diagnosis of pulmonary sequestration.Resection of the lung leads to excellent results and the long-term outcome is highly favorable.
