小儿肺隔离症的诊断及外科治疗

Diagnosis and Surgical Treatment of Child Pulmonary Sequestration

１９９３～１９９８年手术治疗肺隔离症５例，其中叶向型１例、叶外型４例，１例叶外型肺隔离症含二块隔离肺组织、其中一块未见迷走血管。手术方式均为病灶切除，术后随访２个月～５年，效果良好。对儿童病例长期存在的下肺叶肿物，特别是位于左下肺叶者，均应警惕肺隔离症的可能，宜进一步检查明确诊断。叶内型肺隔离症、如病灶位于肺叶表面、胸腔粘连不甚、所附肺叶顺应性良好、可行病灶切除，而不必行肺叶切除术。

Five cases of pulmonary sequestration were treated by surgical operation during 1993~1998, of them one was of intralobar type, the other were of extralobar type. One of the latter 4 cases contained two pieces of sequestered lung tissue, and in one piece no aberrant vessels were observed. The operative mode was all focal excision, and the cases were under follow-up survey for 2 months- 5 years after operation. The results showed that the effects of the treatment were very good. It is suggested that in case of long-standing lump in the lower lobe of lung, especially in the lower lobe of the left lung, we should watch out for the possibility of pulmonary sequestration, and further examinations should be made to verify the diagnosis. As for the intralobar type of pulmonary sequestration, if the fool are located on the surface of lung lobe, the thoracic adhesion is not very severe, and the compliance of the involved lobe is good, it is suitable to conduct focal excision, whereas lobar excision is not necessary.
