“…For example, Torazawa et al described a case of direct vascular injury to the ICA terminus due to high-dose radiation that causes reactive proliferation of the endothelial lining and subendothelial connective tissue, which led to the progressive obliteration of the lumen of the ICA. [Torazawa, 2020]. The development of the de novo AVM after revascularization was described by Fuse et al, who presented the case of an AVM in a child diagnosed 4 years after EDAS for MMD [Fuse, 1996].…”

“…Additionally, few researches described increased level of angiogenic factors in the CSF of patients with MMS that could play an important role in development of the AVM [Schmit, 1996;O'Shaughnessy, 2005]. Later research has proposed the combination of the angiogenic factors of MMS and hemodynamic stress as the triggers of the development of AVM in MMS [Park, 2021;Torazawa, 2020;Mills, 2018]. On the contrary, some studies support the idea of AVM as a causative factor for MMS.…”

“…The prevalence of AVM with involvement of dural arteries linked with MMD is uncertain, with only two previously reported cases of concomitant MMD and dAVF and only two patients characterized as having concurrent MMS and dAVF [ 5 , 9 ]. According to the research, angiogenesis is the mechanism of de novo AVM formation in MMD patients, particularly after stereotactic radiosurgery [ 9 , 11 , 12 ]. However, in this particular case, the patient had no prior history of radiosurgery, which makes it unique.…”

(1) Background: This report describes the surgical management of a case of concurrent AVM with the involvement of dural arteries and moyamoya syndrome. Given the infrequency of this combination, there is currently no established management strategy available. (2) Case Description: A 49-year-old male patient with multiple symptoms including headaches, tinnitus, and visual impairment diagnosed with the coexistence of an arteriovenous malformation with the involvement of dural arteries and moyamoya syndrome was admitted to the national tertiary hospital. The patient underwent surgical management through embolization of the AVM from the afferents of the dural arteries, which has resulted in positive clinical outcomes. However, this approach may not be suitable for all cases, and a multidisciplinary team approach may be required to develop an individualized treatment strategy. (3) Conclusion: The contradictory nature of the treatment approaches in cases of combined AVM with the involvement of dural arteries and MMD highlights the complex nature of this condition and the need for further research to identify the most effective treatment strategies.

“…Fourth, although this review focused on increased flow velocity for the pathogenetic mechanisms, others mentioned that the hemodynamic attenuation changes can likely trigger the development of MMD. A case report demonstrated that decrease in flow velocity in ICA was prior to de novo development of MMD after stereotactic radiosurgery for AVM in a patient with RNF213 mutation (74) . A study with RNF213 knockout mice revealed that induced stenosis of bilateral common carotid arteries promoted further cerebral hypoperfusion (75) .…”

Moyamoya disease (MMD), which commonly exhibits moyamoya vasculopathy characterized by chronic progressive steno-occlusive lesions in the circle of Willis with “moyamoya” collateral vessels, has been well known for its unique demographic and clinical features. Although the discovery of the susceptibility gene RNF213 for MMD revealed the factor for its predominance in East Asians, the mechanisms underlying other predominant conditions (females, children, young to middle-aged adults, and anterior circulation) and lesion formation are yet to be determined. As MMD and moyamoya syndrome (MMS), which secondarily produces moyamoya vasculopathy due to pre-existing diseases, have the same vascular lesions despite differences in their original pathogenesis, they may share a common trigger for the development of vascular lesions. Thus, we herein consider a common trigger from a novel perspective on blood flow dynamics. Increased flow velocity in the middle cerebral arteries is an established predictor of stroke in sickle cell disease, which is often complicated by MMS. Flow velocity is also increased in other diseases complicated by MMS (Down syndrome, Graves’ disease, irradiation, and meningitis). In addition, increased flow velocity occurs under the predominant conditions of MMD (females, children, young to middle-aged adults, and anterior circulation), suggesting a relationship between flow velocity and susceptibility to moyamoya vasculopathy. Increased flow velocity has also been detected in the non-stenotic intracranial arteries of MMD patients. In a pathogenetic overview of chronic progressive steno-occlusive lesions, a novel perspective including the trigger effect of increased flow velocity may provide insights into the mechanisms underlying their predominant conditions and lesion formation.
