Abstract

In this issue, Liu et al[1][1] found that choroidal collateral anastomosis was a predictor of the recurrent hemorrhage of Moyamoya disease (MMD), especially lateral posterior choroidal artery anastomosis. This study will further deepen our understanding of the risk factors of MMD rebleeding. The

Highlights

In this issue, Liu et al[1] found that choroidal collateral anastomosis was a predictor of the recurrent hemorrhage of Moyamoya disease (MMD), especially lateral posterior choroidal artery anastomosis
The common hemorrhage site of MMD is intraventricular hemorrhage, and it is common in the paraventricular area of the posterior lateral ventricle
Intraventricular hemorrhage was associated with recurrent hemorrhage of MMD, and the risk of recurrent hemorrhage in hemorrhagic MMD was 4.3%

Summary

Introduction

Liu et al[1] found that choroidal collateral anastomosis was a predictor of the recurrent hemorrhage of Moyamoya disease (MMD), especially lateral posterior choroidal artery anastomosis. The predominant feature of the pathology of MMD is known to be progressive stenosis of the carotid artery terminations and the development of dilated, fragile perforating arteries, which are termed “Moyamoya vessels.” MMD is an uncommon cerebrovascular disease, it is an important cause of stroke. More than half of adult MMD presents with intracranial bleeding.
