The vein of Galen aneurysmal malformation (VGM) is a rare intracranial arteriovenous fistula with a dramatic manifestation during infancy and 100% mortality without treatment. Therapeutic strategies for VGMs have changed over time as a result of advances in endovascular techniques. We present our experience and multimodality approach within the last 4 decades.
A retrospective analysis and angiographic review were performed of patients with VGM between 1975 and 2016 at our institution.
Eighteen consecutive patients were identified, including 10 with choroidal and 8 with mural VGMs. In 37 endovascular interventions, a transarterial approach was mostly performed (82.8%). One patient was initially treated surgically and received 2 Gamma Knife treatments after multiple embolizations. The preferred embolization agent was histoacryl for choroidal VGMs and a combination of coils and histoacryl for mural VGMs. Total occlusion was achieved in 87.5% of mural VGMs and 11.1% of choroidal VGMs. Cerebral hemorrhages and infarction occurred only in patients younger than 1 month. At a median follow-up interval of 4.6 years, good outcome was achieved in 53.8% and poor outcome in 46.2%, with an overall mortality of 16.7%. Poor outcome was significantly associated with choroidal-type VGMs, age <1 month at first embolization, and incomplete occlusion.
Endovascular embolization using a transarterial approach is the therapy of choice. Gamma Knife radiosurgery can be considered as second-line therapy in a multimodal approach. Whereas treatment within the first month of life is associated with the highest mortality and complications, we did not detect any severe adverse events thereafter.
大脑大静脉动脉瘤样畸形(VGM)是一种罕见的颅内动静脉瘘,在婴儿期表现显著,未经治疗死亡率达100%。由于血管内技术的进步,VGM的治疗策略随时间发生了变化。我们介绍过去40年里我们的经验和多模式治疗方法。
对1975年至2016年在我院诊断为VGM的患者进行回顾性分析和血管造影复查。
共确定18例连续患者,其中脉络丛型VGM 10例,壁型VGM 8例。在37次血管内介入治疗中,大多采用经动脉入路(82.8%)。1例患者最初接受手术治疗,在多次栓塞后接受了2次伽玛刀治疗。脉络丛型VGM首选的栓塞剂是组织黏合剂,壁型VGM则采用弹簧圈和组织黏合剂联合使用。壁型VGM的完全闭塞率为87.5%,脉络丛型VGM为11.1%。脑出血和梗死仅发生在1个月以下的患者中。中位随访期为4.6年,53.8%的患者预后良好,46.2%的患者预后不良,总死亡率为16.7%。预后不良与脉络丛型VGM、首次栓塞时年龄<1个月以及闭塞不完全显著相关。
经动脉入路的血管内栓塞是首选治疗方法。伽玛刀放射外科可作为多模式治疗方法中的二线治疗。虽然出生后第一个月内进行治疗与最高的死亡率和并发症相关,但此后我们未发现任何严重不良事件。
