Background: Rete middle cerebral artery (MCA) is a rare anomaly of the intracranial circulation that mimics congenital Moyamoya disease (MMD). Similar to MMD, it is reported almost exclusively in East-Asian ethnicities. Here, we report 13 patients with rete MCA anomaly from a predominantly non-Asian background in the USA.

While some reports mention bypass surgery for T-MCA, akin to MMD, there is no established treatment method. Previous reports highlight the efficacy of revascularization procedures in preventing recurrent strokes in T-MCA patients, but there is limited data on its usefulness for cases with intracerebral hemorrhagic onset.

Background And Objectives: Moyamoya disease (MMD) is characterized by progressive steno-occlusion of the internal carotid arteries, leading to compensatory collateral vessel formation. The optimal surgical approach for MMD remains debated, with bilateral revascularization potentially offering more comprehensive protection but involving more extensive surgery compared to unilateral revascularization. This study aims to compare bilateral revascularization and unilateral revascularization short-term safety profile in the treatment of MMD.

Background: Moyamoya angiopathy (MMA) is an important cause of juvenile stroke but an overall rare disease among European populations compared with East Asian cohorts. Consecutively, hemorrhagic MMA is described well in East Asian cohorts, but knowledge in non-Asian patients is limited. Literature suggests that disease presentation may vary between those cohorts, also including hemorrhage frequencies.

The authors evaluated the long-term outcomes of their strategy to initially perform unilateral surgery and withhold surgery to the contralateral hemispheres with mild vascular changes and hemodynamic impairment.
Methods: The authors retrospectively evaluated Japanese pediatric patients (onset age ≤ 15 years) diagnosed with bilateral sporadic moyamoya disease who underwent unilateral revascularization.
