Clinical Analysis of Imaging Diagnosis and Interventional Treatment of Pulmonary Arteriovenous Malformations

Objective To discuss the imaging features and the effect of interventional therapy in patients with pulmonary arteriovenous malformations( PAVMs). Methods Retrospective analysis of the clinical data of 15 patients who suffered from with PAVMs intervention therapy in our hospital from Oct 2007 to Nov 2013 were done.. Then summarized the clinical manifestation,imaging features,effect of intervention therapy and discussed the value of intervention therapy. Results 15 patients underwent CTA and showed the feeding arteries,drainage veins of the lesions and the different shape of the aneurysm sac,suggest pulmonary arteriovenous malformation,and the lesions classification,12 cases simple type,3cases complex type. Transcatheterembolization for pulmonary arteriovenous malformations was successfully performed in all15 cases,and 13 patients relative symptoms disappeared after treatment. 2 cases of complex type alleviated after treatment.All operation results were fine,with no serious complication. Conclusion Cases with potential PAVMs should undergo CTA as soon as possible to ensure diagnosis,interventional therapy is a safe and effective treatment method.
