Superficial temporal artery (STA) to middle cerebral artery (MCA) bypass surgery is a common treatment for preventing cerebral ischemia in patients with intracranial artery stenosis. The aim of this study was to analyze the surgical outcomes of the STA-MCA bypass procedure, particularly with regard to the invasiveness of targeted bypass (TB) with preoperative planning using Amira software.
Consecutive patients with single STA-MCA bypass performed by a single neurosurgeon from January 2019 to May 2022 were included. The clinical parameters of seven TB patients were compared with those of 11 patients treated with the conventional method (CM).
Compared with CM patients, TB using Amira software patients had a shorter scalp incision (median [interquartile range]=11.2 [9.7-12.7] cm vs. 16.9 [16.0-17.7] cm, respectively; =0.004], smaller craniotomy size (11.8 [11.5-14.4] cm vs. 20.9 [17.1-22.2] cm, respectively; =0.01], shorter surgery duration (201 [195-218] min vs. 277 [229-310] min, respectively; =0.003], and less intraoperative bleeding (10 [10-20] g vs. 23 [20-50] g, respectively; =0.033]. However, there were no differences in surgical complications between the two groups.
Detailed preoperative evaluation using Amira software can reduce the invasiveness of the STA-MCA bypass procedure.
颞浅动脉（STA）-大脑中动脉（MCA）搭桥手术是预防颅内动脉狭窄患者脑缺血的常用治疗方法。本研究旨在分析STA-MCA搭桥手术的手术效果，特别是关于使用Amira软件进行术前规划的靶向搭桥（TB）的侵袭性。
纳入2019年1月至2022年5月由单一神经外科医生进行单次STA-MCA搭桥手术的连续患者。将7例TB患者的临床参数与11例采用传统方法（CM）治疗的患者的临床参数进行比较。
与CM患者相比，使用Amira软件的TB患者头皮切口更短（中位数[四分位间距]=分别为11.2[9.7-12.7]cm和16.9[16.0-17.7]cm；P=0.004），开颅尺寸更小（分别为11.8[11.5-14.4]cm和20.9[17.1-22.2]cm；P=0.01）手术时间更短（分别为201[195-218]分钟和277[229-310]分钟；P=0.003），术中出血更少（分别为10[10-20]g和23[20-50]g；P=0.033]。然而，两组之间的手术并发症没有差异。
使用Amira软件进行详细的术前评估可以降低STA-MCA搭桥手术的侵袭性。
