Abstract:
Objective To observe the value of CT angiography(CTA)for classifying type of peripheral arteriovenous fistula(AVF)in children.Methods Totally 22 children with peripheral AVF were retrospectively enrolled,the type of AVF was classified with preoperative CTA,and therapeutic planning was developed.Taken digital subtraction angiography(DSA)findings during interventional therapy as gold standards,the efficacy of CTA for classifying type of AVF was analyzed.Results Among 22 cases,DSA detected 3 cases of type Ⅰ,13 cases of type Ⅱa and 6 cases of typeⅡb peripheral AVF,while 3 cases of type Ⅰ,14 cases of type Ⅱa and 5 cases of type Ⅱb peripheral AVF were classified based on CTA.CTA misdiagnosed 1 case of type Ⅱa as type Ⅱb,and 2 cases of type Ⅱb as type Ⅱa peripheral AVF,its accuracy of CTA for classifying type Ⅰ,Ⅱa and Ⅱb peripheral AVF was 100%(3/3),92.31%(12/13)and 66.67%(4/6),respectively.Among 22 cases,13 cases underwent interventional closure,2 cases underwent interventional therapy combined with surgery,while 3 cases did not receive relevant treatment due to drainage vein occlusion.One month after treatments,the symptoms of 19 cases who underwent treatment improved significantly,and no signs of AVF was found with re-examination of ultrasound nor CTA.Conclusion CTA was helpful to classifying type of peripheral AV in children,which could provide references for interventional therapy.
