摘　　要：目的探讨前交通动脉(ACoA)的代偿功能对双侧颈动脉粥样硬化性狭窄患者非术侧颈动脉血流速度测定与狭窄程度评估的影响。方法回顾性连续纳入2019年1月至2021年1月首都医科大学宣武医院神经外科双侧颈动脉粥样硬化性狭窄、接受单侧颈动脉内膜切除术(CEA)且ACoA开放的患者161例。所有患者采用经颅彩色多普勒超声(TCCD)和(或)经颅多普勒超声(TCD)检查,并经DSA和(或)CT血管成像(CTA)证实。依据ACoA开放代偿是否完全,将所有患者分为ACoA开放代偿完全组(69例)和开放代偿不完全组(92例)。比较CEA前后ACoA开放代偿完全组和开放代偿不完全组颈动脉超声(CDU)测得的收缩期峰值流速(PSV)和舒张期末流速(EDV),并将超声与DSA或CTA评估非术侧颈动脉狭窄程度(轻度、中度、重度狭窄)的结果进行一致性分析。结果两组患者年龄、性别及危险因素的差异均无统计学意义(均P>0.05)。CEA后1周内,ACoA开放代偿完全组和开放代偿不完全组的非术侧颈动脉的PSV[分别为(107±35)、(122±40)cm/s]和EDV[分别为(37±12)、(47±16)cm/s]与术前PSV[分别为(177±58)、(163±54)cm/s]和EDV[分别为(64±21)、(76±25)cm/s]比较均下降,差异均有统计学意义(均P<0.01)。在ACoA开放代偿完全组的非术侧颈动脉中,CDU评估颈动脉的狭窄程度与DSA或CTA评估结果存在相对不一致性(Kappa=0.074);DSA或CTA评估为轻度狭窄的58例患者中,55例(94.8%)超声高估为中度狭窄,2例(3.4%)高估为重度狭窄;DSA或CTA评估为中度狭窄的9例患者中,8例超声高估为重度狭窄。ACoA开放代偿不完全组的非术侧颈动脉狭窄程度与DSA或CTA评估结果具有一致性(Kappa=0.920);DSA或CTA评估为轻度狭窄的70例患者中,2例(2.9%)超声高估为中度狭窄;DSA或CTA评估为中度狭窄的9例患者中,1例超声高估为重度狭窄。结论ACoA开放且代偿功能完全的双侧颈动脉粥样硬化性狭窄患者术前非术侧颈动脉PSVObjective To explore the impacts of compensatory function of the anterior communicating artery(ACoA)on the measurement of blood flow velocity and the degree of stenosis of the non-operative carotid artery in patients with bilateral carotid atherosclerotic stenosis.Methods A total of 161 patients with carotid artery stenosis and the ACoA patency,who underwent unilateral carotid endarterectomy(CEA)from January 2019 to January 2021,were enrolled into this study.Examination was performed using transcranial color-coded Doppler(TCCD)and(or)transcranial Doppler ultrasound(TCD)and confirmed by DSA and(or)CT angiography(CTA).According to whether the ACoA compensation was complete,all patients were divided into complete ACoA group(69 cases)and incomplete ACoA group(92 cases).The peak systolic velocity(PSV)and end-diastolic velocity(EDV)measured by the carotid ultrasound were compared between the complete ACoA group and the incomplete ACoA group before and after CEA.In addition,the results of stenosis degree of non-operative carotid artery evaluated by the ultrasound and DSA or CTA were analysed for the consistency.Results There was no significant difference in age,gender and risk factors for cerebrovascular disease between the two groups(all P>0.05).Within 1 week after CEA,the PSV([107±35]cm/s,[122±40]cm/s)and EDV([37±12]cm/s,[47±16]cm/s)of the nonoperative carotid artery decreased significantly when compared with those before CEA in both complete and incomplete ACoA patent groups(PSV[177±58]cm/s,[163±54]cm/s and EDV[64±21]cm/s,[76±25]cm/s,all P<0.01).In the complete ACoA group,the stenosis degrees of non-operative carotid arteries assessed by the CDU were inconsistent with that assessed by the DSA or CTA(Kappa=0.074).Of the 58 patients with mild stenosis assessed by DSA or CTA,55(94.8%)were overestimated as moderate stenosis,and 2(3.4%)were overestimated as severe stenosis.Of the 9 patients with moderate stenosis assessed by DSA or CTA,8 had ultrasound overestimation to severe stenosis.In the incomplete ACoA group
