Abstract
Objective: Superficial temporal artery (STA)-middle cerebral artery (MCA) anastomosis is conducted for flow augmentation. In this study, we measured the STA cut flow of a Korean population and evaluated the relationship between STA cut flow and long-term patency of the bypass.
Methods: A retrospective study was conducted. Intraoperative measurement of STA flow was conducted using a microvascular flow meter on patients who underwent STA-MCA. After cutting the distal end, the STA flow rate was measured with no resistance and recorded. After finishing anastomosis, STA flow was measured and recorded. The cut flow index was calculated by dividing post anastomosis flow by cut flow in intracranial atherosclerotic stenosis patients.
Results: The median STA cut flow was 35.0 mL/min and the post anastomosis flow was 24.0 mL/min. The cut flow of STA decreased with aging (p=0.027) and increased with diameter (p=0.004). The cut flow showed no correlation with history of hypertension or diabetes mellitus (p=0.713 and p=0.786), but did correlate a positively with history of hyperlipidemia (p=0.004). There were no statistical differences in cut flow, STA diameter, and post anastomosis flow between the frontal and parietal branches (p=0.081, p=0.853, and p=0.990, respectively).
Conclusion: The median STA cut flow of a Korean population was 35 mL/min. Upon reviewing previous articles, it appears that there are differences in the STA cut flow between Western and Asian patients.
目的:颞浅动脉(STA)-大脑中动脉(MCA)吻合术是为了增加血流量而进行的。在这项研究中,我们测量了韩国人群的颞浅动脉切口血流量,并评估了颞浅动脉切口血流量与旁路长期通畅性之间的关系:方法:我们进行了一项回顾性研究。方法:这是一项回顾性研究,使用微血管流量计对接受 STA-MCA 手术的患者进行术中 STA 流量测量。切开远端后,在无阻力的情况下测量并记录 STA 流量。完成吻合后,测量并记录 STA 流量。用吻合后血流除以颅内动脉粥样硬化性狭窄患者的切口血流,计算切口血流指数:结果:中位 STA 切断流量为 35.0 mL/min,吻合后流量为 24.0 mL/min。随着年龄的增长,STA 的切口血流量降低(p=0.027),而随着直径的增加(p=0.004)。切口血流与高血压或糖尿病史无相关性(p=0.713 和 p=0.786),但与高脂血症史呈正相关(p=0.004)。额叶分支和顶叶分支的切口血流、STA 直径和吻合后血流没有统计学差异(分别为 p=0.081、p=0.853 和 p=0.990):结论:韩国人的中位 STA 切口血流量为 35 毫升/分钟。回顾以往的文章,西方和亚洲患者的 STA 切流量似乎存在差异。
期刊介绍:
The Journal of Korean Neurosurgical Society (J Korean Neurosurg Soc) is the official journal of the Korean Neurosurgical Society, and published bimonthly (1st day of January, March, May, July, September, and November). It launched in October 31, 1972 with Volume 1 and Number 1. J Korean Neurosurg Soc aims to allow neurosurgeons from around the world to enrich their knowledge of patient management, education, and clinical or experimental research, and hence their professionalism. This journal publishes Laboratory Investigations, Clinical Articles, Review Articles, Case Reports, Technical Notes, and Letters to the Editor. Our field of interest involves clinical neurosurgery (cerebrovascular disease, neuro-oncology, skull base neurosurgery, spine, pediatric neurosurgery, functional neurosurgery, epilepsy, neuro-trauma, and peripheral nerve disease) and laboratory work in neuroscience.
