【摘要】：目的 :分析經(jīng)顱多普勒彩色超聲在新生兒缺氧缺血性腦病(HIE)的診斷價值。方法 :選取我院收治的45例HIE患兒為研究對象,及同期于我院生產(chǎn)的45例健康新生兒為對照組,所有新生兒均于出生后48 h內(nèi)進(jìn)行經(jīng)顱多普勒彩超檢查,分析其彩超結(jié)果及大腦中動脈附近血流動力學(xué)。結(jié)果 :對照組新生兒腦溝及雙側(cè)脈絡(luò)叢回聲較強(qiáng),腦實(shí)質(zhì)組織回聲中等,雙側(cè)基底節(jié)區(qū)回聲較均勻。研究組24例輕度患兒腦實(shí)質(zhì)回聲均勻度較差,回聲表現(xiàn)為略強(qiáng)小點(diǎn)狀,16例中、重度患兒超聲結(jié)果均顯示其側(cè)腦室出現(xiàn)狹窄,腦室旁白質(zhì)回聲增強(qiáng)。研究組新生兒Vs、Vd、Vm均顯著低于對照組,差異具有統(tǒng)計學(xué)意義(P0.05);中、重度組PI顯著高于對照組(P0.05);中、重度組RI0.72或≤0.55與對照組有統(tǒng)計學(xué)意義(P0.05)。結(jié)論 :經(jīng)顱彩超不僅可較為清晰的顯示新生兒顱腦回聲情況,還可有效的探測腦血流動力學(xué)的變化,為HIE的早期診斷提供豐富的參考數(shù)據(jù)支持,值得臨床進(jìn)一步實(shí)踐。
[Abstract]:Objective: to analyze the diagnostic value of transcranial Doppler color ultrasound (TCD) in neonatal hypoxic-ischemic encephalopathy (HIE). Methods: 45 cases of HIE in our hospital and 45 cases of healthy neonates in the same period were selected as the control group. All the newborns were examined by transcranial Doppler ultrasound within 48 hours after birth, the results of color Doppler and hemodynamics near the middle cerebral artery were analyzed. Results: the cerebral sulcus and choroid plexus of the control group had strong echo. The echo of brain parenchyma was moderate and the echo of bilateral basal ganglia was homogenous. In the study group of 24 cases of mild children, the echo degree of brain parenchyma was poor. The VsD V m in the study group was significantly lower than that in the control group, the difference was statistically significant (P 0.05), the Pi in the severe group was significantly higher than that in the control group (P 0.05). Conclusion: transcranial color Doppler sonography can not only clearly display the brain echo of newborn, but also can effectively detect the changes of cerebral hemodynamics in the severe group (RI0.72 or 鈮，
