| 目的 观察CT血管造影（CTA）用于评估儿童外周动静脉瘘（AVF）类型的价值。方法 回顾性纳入22例外周AVF患儿，基于治疗前CTA评估AVF类型并制定治疗方案；以介入治疗中数字减影血管造影（DSA）所见为金标准，观察CTA评估AVF类型的效能。结果 22例中，DSA检出3例Ⅰ型、13例Ⅱa型、6例Ⅱb型外周AVF，CTA评估为3例Ⅰ型、14例Ⅱa型、5例Ⅱb型外周AVF；CTA将1例Ⅱa型误判为Ⅱb型、2例Ⅱb型误判为Ⅱa型，其对3种类型外周AVF的诊断准确率分别为100%（3/3）、92.31%（12/13）及66.67%（4/6）。22例中，13例接受介入封堵、2例接受介入与外科手术联合治疗、3例因引流静脉闭塞而未接受相关治疗；19例接受治疗者1个月后疼痛症状明显改善、患肢肿胀程度减轻，复查超声及CTA均未见AVF征象。结论 CTA有助于评估儿童外周AVF类型并为介入治疗提供参考。 |

| 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 type Ⅱb 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. |
