烟雾病脑室旁异常血管吻合的研究进展

脑室旁异常血管吻合是烟雾病研究中关于侧支血管的新术语，主要包括脉络膜动脉吻合、丘脑动脉吻合和豆纹动脉吻合。据报道，与成人烟雾病患者颅内出血的高风险有关，给患者及其家庭造成重大伤害。近年来，关于烟雾病的侧支血管的研究取得了较多进展，包括侧支血管影像学特点，其与临床症状之间的关系，其自然演变史及在脑血运重建术后的变化等。本文旨在回顾分析关于烟雾病脑室旁异常血管吻合的相关研究，探讨其临床诊疗策略以及未来研究方向。

Anomalous paraventricular anastomosis is a new nomenclature for collateral vessels in the study of moyamoya disease(MMD). It mainly includes choroidal anastomosis, thalamic anastomosis and lenticulostriate anastomosis. According to reports, it is associated with the high risk of intracranial hemorrhage in adult patients with MMD, causing significant harm to patients and their families. In recent years, significant progress has been made in the study of collateral vessels of MMD, including the imaging features, the relationship between collateral vessels and clinical symptoms, the natural history of collateral vessels and their changes after revascularization. This review aims to analyze the recent researches on paraventricular anomalous anastomosis in MMD, explore the treatment strategies, and put forward its research challenges and future research directions.
