The treatment of brain arteriovenous malformations (AVMs) in children has always been a challenge for interventionalists, neurosurgeons, and radiosurgeons. Endovascular embolization is usually performed through transarterial access, but in selected cases the transvenous approach can be considered. The authors of this report aimed to evaluate the efficacy of transvenous embolization in very selected pediatric cases. They describe 4 children treated using transvenous embolization for AVMs that were small, had a single drainage vein, and were deeply located or had a difficult arterial access. The 6-month angiographic and clinical follow-ups are reported as well. In all cases, complete occlusion of the AVM was achieved with no side effects for the patient. Transvenous embolization may represent a promising alternative therapeutic option in very selected cases.
儿童脑动静脉畸形（AVM）的治疗一直是介入放射科医生、神经外科医生和放射外科医生面临的挑战。血管内栓塞通常通过经动脉途径进行，但在某些特定情况下，可以考虑经静脉途径。本报告的作者旨在评估在非常特定的儿科病例中经静脉栓塞的疗效。他们描述了4例使用经静脉栓塞治疗的儿童AVM，这些AVM体积小、有单一引流静脉、位置深或动脉入路困难。同时报告了6个月的血管造影和临床随访情况。在所有病例中，AVM均实现了完全闭塞，且患者无副作用。在非常特定的病例中，经静脉栓塞可能是一种有前景的替代治疗选择。
