A 54-year-old woman presented to our hospital with progressive motor weakness of the right arm. She had a medical history of systemic lupus erythematosus (SLE) and hypothyroidism. Magnetic resonance imaging indicated a watershed infarction of the left hemisphere. Cervical echogram indicated severe stenosis of the internal carotid artery (ICA) without wall thickening. Cerebral angiography indicated left ICA occlusion, development of unilateral moyamoya vessels, and leptomeningeal anastomosis. Encephaloduroarteriosynangiosis (EDAS) was performed after cerebral (99) (m)Technetium-ethyl-cysteinate-dimer single-photon emission computed tomography indicated a decreased cerebral blood flow, diminished cerebrovascular perfusion reserve. Motor weakness finally disappeared 6 months after surgery. Moyamoya syndrome is a rare complication of both SLE and hypothyroidism, and the surgical indication remains controversial. By evaluating the decreased cerebral perfusion reserve capacity and the existence of leptomeningeal anastomosis, EDAS could be an efficient method for the treatment of moyamoya syndrome associated with SLE and hypothyroidism.

Objective: The leptomeningeal ivy sign is a distinctive finding of moyamoya disease (MMD), characterized by a linear high signal intensity along the cortical sulci on contrast-enhanced T1 magnetic resonance imaging (MRI) and fluid-attenuated inversion-recovery MRI. We recently identified a similar linear enhancement along the cortical sulci using gadolinium-enhanced vessel wall MRI (VWMR) in patients with MMD. The aim of this study was to introduce the concept of the "VWMR ivy sign (VIS)".

Purpose: Bypass surgery is regarded as the standard treatment option for symptomatic and hemodynamically unstable moyamoya disease (MMD). However, there is ongoing debate about the most effective type of bypass surgery. We aimed to analyze the long-term outcomes of combined and indirect bypasses for MMD patients through intra-individual comparisons.

The efficacy of preoperative radiotherapy combined with surgery (preRT + S) for primary retroperitoneal sarcoma (RPS) remains unclear. This study aimed to compare preRT + S with surgery alone (SA) in patients with RPS. Core databases were searched for directly comparative studies depending on preRT.

Methylenetetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) polymorphisms are known risk factors for vascular diseases due to the impact on folate metabolism dysfunction and homocysteine (Hcy) accumulation. This study aimed to investigate the association between folate metabolism risk and hemorrhagic risk in moyamoya disease (MMD). In this prospective study, we enrolled 350 MMD patients with complete genotype data for MTHFR and MTRR.

Objectives: Moyamoya disease (MMD) is a rare cerebrovascular condition, and it is a well-known risk factor of acute ischemic stroke (AIS). While IV thrombolysis (IVT) is an established treatment for patients with AIS, its efficacy and safety for patients with MMD is largely unknown.
Methods: This was a large retrospective analysis of the 2016-2021 Nationwide Readmissions Database in the United States.
