Moyamoya disease (MMD) suffers from impaired cerebrovascular hemodynamics and high perioperative complications occurrence. This study aims to propose and evaluate the relationship between intraoperative hemodynamics and perioperative complications, and propose a potential compensatory self-recirculation network in MMD. We prospectively enrolled 63 MMD patients undergone combined revascularization, and patients were divided into decreased and increased group according to decreased and increased microvascular transit time (MVTT), respectively. Mean age of all patients was 45.9 ± 9.4 years. The post-bypass hyperperfusion syndrome occurrence was significantly higher in the decreased MVTT group, and the cerebral infarction occurrence was significantly higher in the increased MVTT group. For the hemodynamics of the recipient artery around anastomosis, the parameters of distal site demonstrated a significant higher intensity and shorter time in the decreased MVTT group, while the parameters of the proximal site demonstrated a significant higher intensity and shorter time in the increased MVTT group. Pre-bypass and post-bypass collision of blood flow in artery and vein were firstly observed and illustrated. Intraoperative hemodynamics showed close relationship with perioperative complications. The blood flow of MMD seems to develop a unique compensatory self-recirculation system and contribute to the clinical complications, providing a new insight to the clinical management the pathology of the disease.
烟雾病(MMD)存在脑血管血流动力学受损和围手术期高并发症发生率的问题。本研究旨在提出并评估术中血流动力学与围手术期并发症之间的关系,并提出 MMD 中潜在的代偿性自循环网络。我们前瞻性纳入 63 例行联合血运重建的 MMD 患者,根据微血管转运时间(MVTT)的降低和升高,将患者分为降低组和升高组。所有患者的平均年龄为 45.9±9.4 岁。在降低 MVTT 组,术后过度灌注综合征的发生率明显更高,而在升高 MVTT 组,脑梗死的发生率明显更高。对于吻合口周围受区动脉的血流动力学,降低 MVTT 组的远侧部位参数表现出明显更高的强度和更短的时间,而升高 MVTT 组的近侧部位参数表现出明显更高的强度和更短的时间。首次观察并图示了术前和术后动脉和静脉血流的碰撞。术中血流动力学与围手术期并发症密切相关。MMD 的血流似乎形成了一种独特的代偿性自循环系统,导致了临床并发症,为该疾病的临床治疗提供了新的视角。
