【摘要】：目的探討經(jīng)顱彩色多普勒超聲(TCCS)診斷顱內(nèi)段椎動(dòng)脈狹窄的血流動(dòng)力學(xué)參數(shù)標(biāo)準(zhǔn)。方法回顧性納入622例門診或住院可疑后循環(huán)缺血患者,從中選取經(jīng)TCCS、彩色多普勒血流顯像(CDFI)篩查和DSA檢查的患者共216例,其中顱內(nèi)椎動(dòng)脈正常者33例(15.3%),狹窄率50%者45例(20.8%),狹窄率為50%~69%者44例(20.4%),狹窄率為70%~99%者94例(43.5%)。通過檢測(cè)顱內(nèi)段椎動(dòng)脈、椎間隙段收縮期峰值流速(PSV1、PSV2)和舒張期末流速(EDV1、EDV2),分別計(jì)算顱內(nèi)段平均流速(MV)、顱內(nèi)段與椎間隙段收縮期峰值流速、舒張期末流速的比值SPRP(PSV1/PSV2)、SPRE(EDV1/EDV2)。以DSA檢查結(jié)果為標(biāo)準(zhǔn),計(jì)算受試者工作特征(ROC)曲線下面積,獲得最佳截?cái)帱c(diǎn)。結(jié)果 TCCS診斷顱內(nèi)段椎動(dòng)脈狹窄血流動(dòng)力學(xué)參數(shù)最佳截?cái)帱c(diǎn)分別為:狹窄率50%的參數(shù)標(biāo)準(zhǔn)為110 cm/s≤PSV1≤145 cm/s,65 cm/s≤MV≤85 cm/s;狹窄率為50%~69%的參數(shù)標(biāo)準(zhǔn)為145 cm/s≤PSV1≤190 cm/s,85 cm/s≤MV≤115 cm/s;狹窄率為70%~99%的參數(shù)標(biāo)準(zhǔn)為PSV1≥190 cm/s,MV≥115 cm/s。結(jié)論 TCCS可有效評(píng)價(jià)顱內(nèi)段椎動(dòng)脈狹窄的血流動(dòng)力學(xué)變化,為顱內(nèi)段椎動(dòng)脈狹窄的超聲評(píng)判標(biāo)準(zhǔn)提供參考。
[Abstract]:Objective to investigate the criteria of hemodynamic parameters for diagnosis of intracranial vertebral artery stenosis by transcranial color Doppler ultrasound (TCCS). Methods A total of 622 patients with suspected posterior circulation ischemia were enrolled retrospectively. 216 patients were screened by TCCS, CDFI by color Doppler flow imaging (CDFI) and examined by DSA. Among them, there were 33 cases with normal intracranial vertebral artery, 45 cases with 50% stenosis, 44 cases with 20.4% with 50% stenosis, and 94 cases with 43.5% stenosis. The peak systolic velocity (PSV1PSV2) and the end-diastolic velocity (EDV1 / EDV2) of intracranial vertebral artery and intervertebral space were measured, respectively. The mean flow velocity of intracranial segment and the ratio of peak systolic velocity of intracranial segment to intervertebral segment, the ratio of peak systolic velocity of intracranial segment to intervertebral segment, and the ratio of peak systolic velocity of intracranial segment to intervertebral segment and end-diastolic velocity of PSV1 / PSV2EDV2 were calculated respectively. The area under the ROC curve was calculated according to DSA results and the optimum truncation point was obtained. Results the best truncation points of hemodynamic parameters for diagnosis of intracranial vertebral artery stenosis were as follows: the parameter standard of 50% stenosis rate was 110 cm/s 鈮，
