摘要
目的 探讨儿童肝动脉 门静脉瘘的数字减影血管造影 (DSA)诊断及其临床意义。方法 回顾性分析 1997～ 2 0 0 1年 8例肝动脉 门静脉瘘患儿的肝动脉造影DSA图像 ,观察其特征性血管造影表现 ;通过与CT及超声图像比较 ,评价其对临床诊断及治疗的作用。结果 CT及超声诊断不明的 8例患儿经皮股动脉穿刺行肝动脉造影均能清晰显示 :肝动脉增粗 ,动脉期见大量的门静脉分支及主干显影。在DSA下导管顺利插入肝动脉 ,并注入聚乙烯醇颗粒进行扩充术 ,术后造影复查见肝动脉 门静脉瘘消失。结论 经皮肝动脉DSA对肝 门静脉分支瘘的诊断和治疗具有重要价值。
Objective To evaluate the efficacy and clinical significance of percutaneous selective hepatic arteriography in the diagnosis of hepatic-portal arteriovenous fistula (AVF) in children.Methods Digital subtraction angiography (DSA) images of hepatic arteriography were retrospectively analyzed in 8 children with AVF. The imaging manifestation of AVF was evaluated and summarized, and the advantage of DSA compared with ultrasound and CT was discussed.Results All 8 cases showed clear contrast opacification in main trunk and branches of portal vein during artery phase. Four cases that could not be diagnosed by ultrasound and 6 cases without abnormality in CT were also diagnosed by hepatic arteriography. All cases were successfully treated by transarterial embolization under DSA. Conclusions Percutaneous selective hepatic arteriography is effective and of great value for the diagnosis of AVF in children, and is helpful for further treatment.
