Abstract
BACKGROUND AND PURPOSE A ruptured peripheral cerebral aneurysm (PPCA) associated with moyamoya disease (MMD) is a rare but potentially life-threatening condition with controversial management strategies. We aim to summarize the clinical characteristics, treatment strategies, and prognostic factors of PPCAs in MMD. METHODS We reviewed studies published in PubMed between 1980 and 2023 and used logistic regression analysis to identify the risk factors for adverse outcomes. RESULTS Of 425 identified studies, 48 eligible studies involving 121 participants were included in the current study. The mean age at diagnosis was 40.8±15.1 years, with a peak age of onset between 41 and 50 years. Among the identified participants, 59.6% were female, and 55.9% presented with impaired consciousness. Aneurysms were present in the posterior (35.5%) or anterior (30.6%) choroidal arteries in 66.1% of the cases, and 71.1% of the patients presented with intraventricular hemorrhage (IVH) with or without intracerebral hematoma (ICH). The treatment strategies were embolization (28.9%), direct surgery (21.5%), revascularization (22.3%), and conservation (27.3%). Favorable outcomes were achieved in 86.8% of all cases, with 97.1% for embolization, 65.4% for direct surgery, 96.3% for revascularization, and 84.8% for conservative treatment. Aneurysm rebleeding occurred in 11 (26.8%) of 41 patients managed conservatively, leading to worse outcomes in 7 patients (63.6%). Impaired consciousness (odds ratio [OR], 8.61; 95% confidence interval [CI], 2.06-36.00) and aneurysm rebleeding (OR, 16.54; 95% CI, 3.08-88.90) independently predicted poor outcomes. CONCLUSION PPCA should be considered in patients with hemorrhagic MMD, particularly those with IVH with or without ICH. Endovascular and bypass treatments are recommended as first-line options, with direct open surgery as an alternative in urgent hematoma evacuation cases. Detailed preoperative planning and intraoperative technical assistance are necessary to reduce procedure-related complications. Conservative management should be selected with caution because of the high risk of rebleeding and poor outcomes. Impaired consciousness and aneurysm rebleeding appeared to be independent risk factors for adverse prognoses. We emphasize that treatment selection should be personalized, and the potential benefits should be weighed against the associated risks.

Abstract
Peripheral aneurysms in patients with moyamoya disease have been reported to be hazardous owing to their rupture-prone nature. High-resolution vessel wall imaging has recently emerged as a useful modality for evaluating intracranial aneurysmal status. We present the vessel-wall imaging of peripheral aneurysms in three patients with moyamoya disease. Strong circumferential wall enhancement was observed in ruptured peripheral aneurysms. Peripheral aneurysms were located at the connection point between the single main stem and the multiple medullary tributaries of the choroidal anastomosis. Using high-resolution vessel-wall imaging, we identified the characteristics of peripheral aneurysms in patients with moyamoya disease.

Abstract
Background Aneurysms in moyamoya vessels or on collaterals are difficult to treat. Parent artery occlusion (PAO) via endovascular treatment (EVT) is often the last resort, but the safety and efficacy of this approach need to be evaluated. Materials and methods A retrospective study was performed on patients admitted to our hospital who were diagnosed with unilateral or bilateral moyamoya disease (MMD) associated with ruptured aneurysms in moyamoya vessels or on collaterals. These aneurysms were treated with PAO, and the clinical outcome was recorded. Results Eleven patients were aged 54.7 ± 10.4 years, and six patients were male (54.5%, 6/11). The aneurysms in 11 patients were single and ruptured, and the average size was 2.7 ± 0.6 mm. Three (27.3%, 3/11) aneurysms were located at the distal anterior choroidal artery, 3 (27.3%, 3/11) were at the distal lenticulostriate artery, 3 (27.3%, 3/11) were at the P2-3 segment of the posterior cerebral artery, 1 (9.1%, 1/11) was at the P4-5 segment of the posterior cerebral artery, and 1 was at the transdural location of the middle meningeal artery. Among the 11 aneurysms, PAO by coiling was performed on 7 (63.6%, 7/11), and Onyx casting was performed on 4 (36.4%, 4/11). Of 11 patients, 2 (18.2%, 2/11) suffered intraoperative hemorrhagic complications. During follow-up, all patients had good outcomes with a modified Rankin scale score of 0-2. Conclusion As a last resort, the application of PAO with coiling or casting Onyx for ruptured aneurysms in moyamoya vessels or on collaterals may be safe with an acceptable clinical outcome. However, patients with MMD may not always achieve expected health outcomes, and PAO for the aneurysm can bring only temporary relief.

Abstract
Ruptured choroidal microaneurysms associated with moyamoya syndrome are rare entities. Their small size and deep/distal location make them challenging to treat. Both surgical and endovascular treatment options carry significant risk of stroke. Here we present a two-patient case report of ruptured choroidal microaneurysms treated with Nbutyl cyanoacrylate (nBCA) endovascular embolization utilizing neuromonitoring and provocative testing during one of the cases. We also present a review of the literature evaluating surgical and endovascular treatment of these aneurysms.

Treatment of ruptured aneurysms of the choroidal collateral system in moyamoya disease: a systematic review and data analysis. J Neurosurg 2021; 136:637-646.

Abstract
OBJECTIVE Moyamoya disease (MMD) is a chronic, progressive steno-occlusive condition of the distal internal carotid arteries of unknown etiology. Collateral arterial networks typically develop in MMD, bypassing the steno-occlusion. Aneurysms arising on the collateral networks are a known source of hemorrhage. The choroidal collateral system is the most common location for collateral pathway aneurysms in MMD and associated hemorrhage. The authors performed data collection and analysis to further elucidate the best treatment approaches for ruptured aneurysms of the choroidal collateral system in MMD, which as yet remain unclear. METHODS A comprehensive data collection and analysis of case reports and case series with ruptured choroidal collateral artery aneurysms (CCAAs) was performed. PRISMA guidelines for systematic reviews were followed and the Medline, Embase, and Scopus databases were searched for relevant studies. A database was created including patients with ruptured CCAA in MMD. Original data from case series were included whenever possible. A previously unreported case of a ruptured choroidal artery aneurysm in MMD treated by the authors was also included. RESULTS The database comprised 72 patients with ruptured CCAA in MMD. The most common clinical symptoms were headache, nausea, and vomiting (39%). Initially, a conservative treatment approach was chosen in 29% of cases but led to rehemorrhage in 40% of cases; 63% of these rehemorrhages occurred during the first 35 days. Endovascular treatment seemed a safe option for aneurysm exclusion, mainly through parent vessel sacrifice, but had a treatment failure rate of 21%, due to inadequate access. Aneurysm treatment with revascularization as the initial treatment strategy led to aneurysm regression in 82% with no reported rehemorrhage. Aneurysm exclusion through open surgery was effective but was associated with a relatively high complication rate (25%). Outcome after rupture of CCAA was poor, with 41% of patients deceased or permanently disabled. Overall, patient outcomes were better in the endovascular and revascularization treatment group than in the conservative treatment group. CONCLUSIONS Rupture of CCAA in MMD is associated with high morbidity and rerupture rate requiring urgent treatment.

Abstract
Peripheral collateral vessel aneurysms in Moyamoya disease (MMD) remain difficult to treat due to their deep location, small size, and vascular fragility. We report the case of an aneurysm localized in the hypothalamus, which was rapidly increasing in size with repeated hemorrhage despite revascularization surgery. Aneurysm clipping was performed to prevent further progress and rerupture with favorable outcome. To our best knowledge, this is the first description of a hypothalamic aneurysm in MMD being clipped via a transcallosal, transchoroidal approach through the third ventricle.

Abstract
There is little information regarding severe intraventricular hemorrhage casting associated with moyamoya disease. Performing only external ventricular drainage in such a case is preferred way, however, there are no scientific date supporting this rule. This is the description of aspiration of severe intraventricular hemorrhage in moyamoya disease patients in acute phase. Our two cases suggested that early endoscopic aspiration of severe intraventricular hemorrhage may prevent poor outcomes.
Introduction When severe intraventricular hemorrhage (IVH) casting in moyamoya disease (MMD) is mentioned, experts advocate not to evacuate the IVH in acute phase. However, the devastating outcomes derived from this empirical rule have not been addressed. Herein, we report two MMD cases undergoing obliteration of ruptured aneurysm and early complete aspiration of severe IVH casting, and showed good outcomes. Presentation of cases Case 1: A 55-year-old woman was admitted to our hospital. Her initial Glasgow Coma Scale (GCS) was 4 and a computerized tomography (CT) scan showed severe IVH. Cerebral angiography (CAG) revealed MMD and an aneurysm. Direct surgery was performed for the ruptured aneurysm, followed by endoscopic complete aspiration of residual IVH. The modified Rankin Scale (mRS) was 1 at discharge. Case 2: A 44-year-old woman was admitted to our hospital. Her initial GCS was 4 and the CT scan showed a severe IVH. CAG revealed MMD and an aneurysm. Transcatheter arterial embolization was carried out for the aneurysm, followed by endoscopic complete aspiration of the residual IVH. The mRS was 2 at discharge. Discussion Performing only external ventricular drainage in acute phase for such IVH casting is generally preferred way, however, there are no scientific date supporting this empirical rule. Early surgical removal of severe IVH casting is an approach for severe IVH casting in MMD. Conclusion Early aspiration of severe IVH casting is an option for managing MMD with critical intracranial pressure, and it has the potential to prevent poor outcomes in MMD patients with severe IVH.

Location-based treatment of intracranial aneurysms in moyamoya disease: a systematic review and descriptive analysis. Neurosurg Rev 2020; 44:1127-1139. [PMID: 32385590 DOI: 10.1007/s10143-020-01307-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Revised: 04/12/2020] [Accepted: 04/23/2020] [Indexed: 12/20/2022]
Abstract
We conducted a systematic review of the literature to evaluate the efficacy of various treatment modalities for intracranial aneurysms (IA) in patients with moyamoya disease (MMD) based on anatomical location of IA. A comprehensive review of studies documenting single cases or series of MMD patients with concomitant IA was conducted. Aneurysms were classified into two primary anatomical categories: those of the Circle of Willis (CoW) and those of peripheral "moyamoya" collateral vessels. Conservative, endovascular, and open surgical treatment modalities and their outcomes between each anatomical subgroup were descriptively compared. A total of 124 studies consisting of 275 patients with 313 IA were included. Of all IA, 59.6% were located on CoW vessels, 33.7% on peripheral vessels, and 6.7% in "other" locations. Of all CoW IA, 87.2% treated with endovascular techniques had no or minimal deficit at follow-up as compared with 56.7% of those treated with open surgery. Ninety-five percent of patients with peripheral aneurysms treated with endovascular therapy had no or minimal deficit, in contrast to open surgery (69.6%). Of peripheral IA treated conservatively with or without revascularization, 65.7% had spontaneous resolution as compared with 12.0% IA of the CoW. Our results support the use of endovascular techniques for direct treatment of both CoW and peripheral IA. Aneurysms of peripheral vessels respond well to indirect treatment through surgical revascularization as opposed to CoW aneurysms. The quality of evidence is limited due to heterogeneity of included studies and IA management in MMD patients should be considered in a case-specific manne.

The prospects and pitfalls in the endovascular treatment of moyamoya disease-associated intracranial aneurysms. Neurosurg Rev 2020; 44:261-271.

Abstract
Moyamoya disease (MMD) is characterized by progressive stenosis or occlusion of the distal internal carotid artery and simultaneous formation of collateral vasculature. The fragile alteration and increased hemodynamic stress in the intra- and extracranial vasculature would conjointly result in the formation of intracranial aneurysms in MMD patients. According to our classification, the MMD-associated aneurysms are divided into the major artery aneurysms (MAAs) and non-MAAs. The non-MAAs are further subdivided into the distal choroidal artery aneurysms, moyamoya vessel aneurysms, transdural collateral aneurysms, and anastomosis aneurysms. Currently, endovascular treatment (EVT) has become the main stream for the MMD-associated aneurysms. There is no difference to EVT for the MMD-associated MAAs of the non-stenosed major arteries with that in the non-MMD patients. While it is a big challenge to perform EVT for MMD-associated aneurysms in the stenosed arteries. Generally speaking, the parent arteries of the non-MAAs are slim, and super-selective catheterization is technically difficult. Most of the times, parent artery occlusion with liquid embolic agents or coils can only be performed. The vasculature in MMD patients is fragile; perioperative management and meticulous intraoperative manipulation are also very important to avoid complications during EVT. In spites of the complications, the EVT can bring good outcome in selected cases of MMD-associated aneurysms.
