Twenty patients with cerebral arteriovenous malformations (AVMs) were followed up by angiography. Of the 20 AVMs, 16 were nontreated and the remaining 4 were residual. The follow-up periods between the two examinations were from 5 to 28 years, with a median interval of 15 years. At follow-up, the size of the AVM had increased in 4 patients (20%), decreased in 4 (20%), totally regressed in 4 (20%), and was unchanged in 8 (40%). In cases of enlarged AVMs, the patients were all young: from 0 to 11 years old at first angiography and from 6 to 30 at second angiography. The decrease or total regression of the AVM occurred in older patients (over 30 years old at second angiography), and the AVMs were relatively small and fed by single or a few feeders. The patient's age and the size of AVM should be considered when operative indications are discussed.
对20例脑动静脉畸形（AVM）患者进行了血管造影随访。在这20个AVM中，16个未接受治疗，其余4个为残留病变。两次检查之间的随访期为5至28年，中位间隔为15年。随访时，AVM大小增加的有4例（20%），减小的有4例（20%），完全消退的有4例（20%），不变的有8例（40%）。在AVM增大的病例中，患者均为儿童：首次血管造影时年龄为0至11岁，第二次血管造影时为6至30岁。AVM减小或完全消退发生在年龄较大的患者中（第二次血管造影时超过30岁），且AVM相对较小，由单一或少数供血支供血。在讨论手术指征时应考虑患者年龄和AVM大小。
