Two cases of aneurysmal malformations of the vein of Galen with later spontaneous thrombosis are reported. Angiograms before thrombosis in both cases showed mural type aneurysmal malformations of the vein of Galen with slow arteriovenous shunts and associated stagnation of contrast in the venous sac secondary to severe outflow restriction. Based on these angiographic findings, the patients were managed conservatively and the arteriovenous malformations of the vein of Galen thrombosed with good clinical outcomes. Twenty cases of spontaneous thrombosis previously reported in the literature are reviewed.
报告了两例Galen静脉瘤样畸形伴随后自发性血栓形成的病例。两例病例在血栓形成前的血管造影显示Galen静脉的壁型瘤样畸形，伴有缓慢的动静脉分流以及由于严重的流出道受限导致静脉囊内造影剂滞留。基于这些血管造影结果，对患者进行了保守治疗，Galen静脉的动静脉畸形发生血栓形成，临床结果良好。对文献中先前报道的20例自发性血栓形成病例进行了回顾。
