Abstract

Background: Flow-related aneurysms (FRAs) associated with cerebral arteriovenous malformations (AVMs) pose a significant therapeutic challenge. Both their natural history and management strategy are still unclear and underreported. FRAs generally increase the risk of brain hemorrhage. However, following AVM obliteration these vascular lesions are expected to disappear or remain stable.

Methods: We present two cases where growth of FRAs was detected following complete obliteration of an unruptured AVM.

Results: The first patient presented with proximal middle cerebral artery (MCA) aneurysm growth after spontaneous and asymptomatic thrombosis of the AVM. In our second case, a very small aneurysmal-like dilation located at the basilar apex enlarged to a saccular aneurysm following complete endovascular and radiosurgical obliteration of the AVM.

Conclusion: The natural history of flow-related aneurysms is unpredictable. In the cases where these lesions are not managed first, there should be close follow-up. When aneurysm growth is evident, active management strategy seems mandatory.

脑动静脉畸形闭塞后与血流有关的动脉瘤生长

背景：与脑动静脉畸形（AVMs）相关的血流相关动脉瘤（FRAs）给治疗带来了巨大挑战。其自然病史和治疗策略仍不明确，且报告不足。FRA 通常会增加脑出血的风险。然而，在 AVM 消除后，这些血管病变有望消失或保持稳定：我们介绍了两例在未破裂的 AVM 完全阻塞后发现 FRA 生长的病例：结果：第一例患者在 AVM 自发无症状血栓形成后出现大脑中动脉 (MCA) 近端动脉瘤增生。在我们的第二例患者中，位于基底动脉顶的一个非常小的动脉瘤样扩张在血管内和放射外科手术完全清除 AVM 后扩大为一个囊状动脉瘤：结论：血流相关动脉瘤的自然病史难以预测。结论：血流相关动脉瘤的自然病史是不可预测的，在未首先处理这些病变的情况下，应进行密切随访。当动脉瘤明显增大时，必须采取积极的治疗策略。

期刊介绍： The Journal of Neurological Surgery Part A: Central European Neurosurgery (JNLS A) is a major publication from the world''s leading publisher in neurosurgery. JNLS A currently serves as the official organ of several national neurosurgery societies. JNLS A is a peer-reviewed journal publishing original research, review articles, and technical notes covering all aspects of neurological surgery. The focus of JNLS A includes microsurgery as well as the latest minimally invasive techniques, such as stereotactic-guided surgery, endoscopy, and endovascular procedures. JNLS A covers purely neurosurgical topics.
