Evaluation of the congenital vascular lesions of the brain requires multiple conventional intra-arterial digital subtraction angiographic examinations which have many associated risks including exposure to ionizing radiations. Magnetic resonance digital subtraction angiography is a non-invasive procedure with no related risks of radiation exposure. This technique can be of greater clinical significance in diagnosis and treatment planning of neurovascular abnormalities among children who are at far greater risk of invasive procedures like intra-arterial digital subtraction angiography.
We report a congenital pial arteriovenous fistula in an infant which is a rare vascular lesion and has recently been identified as different from other vascular malformations. Magnetic resonance digital subtraction angiography provided hemodynamic information in absolute agreement with intra-arterial digital subtraction angiography indicating its significance in evaluating vascular lesions.
Magnetic resonance digital subtraction angiography can be used in children in conjunction with intra-arterial digital subtraction angiography to minimize the cumulative radiation dose and multiple anesthesias.
评估脑部先天性血管病变需要进行多次传统的动脉内数字减影血管造影检查，这些检查存在许多相关风险，包括暴露于电离辐射。磁共振数字减影血管造影是一种非侵入性检查，不存在辐射暴露的相关风险。对于像动脉内数字减影血管造影这样的侵入性检查风险高得多的儿童，这项技术在神经血管异常的诊断和治疗规划中可能具有更大的临床意义。
我们报告了一例婴儿先天性软脑膜动静脉瘘，这是一种罕见的血管病变，最近已被确定与其他血管畸形不同。磁共振数字减影血管造影提供的血流动力学信息与动脉内数字减影血管造影完全一致，表明其在评估血管病变中的重要性。
磁共振数字减影血管造影可与动脉内数字减影血管造影联合用于儿童，以尽量减少累积辐射剂量和多次麻醉。
