Abstract

Background: Digital subtraction angiography (DSA), the gold standard for the diagnosis of intracranial arteriovenous malformations (AVMs), can show clean nidus resection, leading to a perceived cure. Most cases of intracranial AVM recurrence have been reported in pediatric patients. The conventional understanding indicates that AVMs arise when abnormal blood vessels develop between the fourth and eighth weeks of embryonic development, which coincides with the typical period of blood vessel formation in the brain. As such, recurrent ectopic AVM are rare in adults.

Case summary: Herein, we present the case of a 31-year-old adult with a history of an intracranial AVM originally diagnosed with a symptomatic de novo cerebellar AVM formation. Recurrence was observed five years following angiographically-confirmed excision of the initial AVM. DSA performed prior to initial AVM resection indicated no cerebellar abnormalities. Moreover, the recurrent arteries exhibited differences in arteries and draining veins. In addition to reporting this case, we analyzed six previously-reported adult patients with similar ectopic recurrent AVMs. These cases are summarized to review and explore the potential causes of ectopic AVM recurrence in adults, which increase the likelihood of acquired AVM.

Conclusion: The clinical course of the reported patients demonstrated the possibility of ectopic AVM recurrence in adults. The median time between the diagnosis of the initial AVM and the occurrence of ectopic recurrent AVM in adults was 11 years (range: 5-20 years). Magnetic resonance imaging follow-up for more than 10 years may be required in adult AVM-treated patients.

成人动静脉畸形治疗后的异位复发:病例报告和文献综述。
背景:数字减影血管造影术(DSA)是诊断颅内动静脉畸形(AVM)的金标准,可显示干净的瘤巢切除,从而达到治愈的目的。大多数颅内动静脉畸形复发病例都发生在儿童患者身上。传统观点认为,动静脉畸形是在胚胎发育的第 4 至第 8 周出现异常血管时产生的,而胚胎发育的第 4 至第 8 周恰好是脑血管形成的典型时期。因此,复发性异位 AVM 在成人中非常罕见。病例摘要:本病例是一名 31 岁的成人,曾有颅内 AVM 病史,最初被诊断为无症状的新发小脑 AVM 形成。经血管造影证实切除初始 AVM 五年后发现复发。在切除最初的动静脉畸形之前进行的 DSA 显示小脑没有异常。此外,复发动脉在动脉和引流静脉方面存在差异。除报告本病例外,我们还分析了之前报告过的六名患有类似异位复发性 AVM 的成人患者。总结这些病例是为了回顾和探讨成人异位 AVM 复发的潜在原因,这些原因增加了获得性 AVM 的可能性:结论:所报告患者的临床病程证明了成人异位 AVM 复发的可能性。成人从诊断出最初的 AVM 到发生异位复发 AVM 的中位时间为 11 年(范围:5-20 年)。接受过 AVM 治疗的成人患者可能需要磁共振成像随访 10 年以上。
