The evaluation of the imaging diagnosis of congenital pulmonary arteriovenous fistula

目的 :探讨先天性肺动静脉瘘影像诊断特点。方法 :分析 11例先天性肺动静脉瘘平片、CT、MRI和肺动脉血管造影表现。结果 :按病变形态与影像表现 ,先天性肺动静脉瘘分为三型 :6例为单纯型 ,4例为复杂型 ,1例为弥漫型。结论 :肺动脉血管造影是确诊本病的重要手段 。

Objective:To approach the characteristics of correlative image of congenital pulmonary arteriovenous fistula(CPAVF).Methods:To analyze the plain films, CT and MRI, as well as the pulmonary arterographies of 11 cases of CPAVF.Results:The image of CPAVF can be divided into 3 types: simple type 6 cases, complex type 4 cases,diffuse type 1 case.Conclusion:The pulmonary arterographies can be used to confirm the diagnosis of CPAVF and to choose the proper therapies.
