肺隔离症影像诊断与介入治疗

肺隔离症是临床比较少见的先天性肺发育异常疾病,占所有肺发育畸形的0.15%~6.4%。X线、CT、MRI等影像检查在肺隔离症的诊断中发挥着重要的作用,尽管DSA被认为是其诊断的金标准,但MSCT三维血管重建可以清晰显示供血动脉和引流静脉,有利于手术前了解血管情况。目前,肺隔离症的主要治疗方法仍为外科手术,但介入治疗创伤小、费用低,且具有良好的发展前景。总结分析肺隔离症的影像表现、鉴别诊断,并就肺隔离症的介入治疗展开讨论。

Image diagnosis and interventional treatment of pulmonary sequestration

Pulmonary sequestration (PS) is a rare congenital dysplasia of the lung disease, accounting for about 0.15%to 6.4%of all lung malformations. Radiological exam including X-ray, CT, and MRI, plays an important role in the diagnosis of PS. DSA aortography is considered to be the golden standard for diagnosing PS. While 3D vascular reconstruction of MSCT can be used to inspect feeding arteries and draining veins. Today, although PS patients could be aggressively treated with surgery, minimally invasive and economic interventional therapy becomes a promising choice. In this paper, we summarized the imaging manifestations and differential diagnosis of PS, and discussed about interventional treatment.
