【摘要】：目的:探討T2 FLAIR序列血管高信號(hào)征(HVS)在大腦中動(dòng)脈供血區(qū)梗死患者的影像表現(xiàn)及臨床預(yù)后應(yīng)用價(jià)值。方法:回顧性分析經(jīng)頭顱MRI檢查的90例大腦中動(dòng)脈供血區(qū)梗死伴相應(yīng)臨床表現(xiàn)的患者,分析比較遠(yuǎn)端HVS組與無(wú)遠(yuǎn)端HVS組高血壓、高血脂等一般臨床資料、ASPECTS評(píng)分應(yīng)用和不同時(shí)期NIHSS評(píng)分之間的差異。同時(shí)間收集同一時(shí)期73例非腦梗死患者,觀察HVS征像顯示情況。結(jié)果:1、90例梗死患者中,遠(yuǎn)端HVS組48例,無(wú)遠(yuǎn)端HVS組42例,兩組一般臨床資料均無(wú)統(tǒng)計(jì)學(xué)差異(P0.05)。2、遠(yuǎn)端HVS組梗死腦葉范圍低于無(wú)遠(yuǎn)端HVS組,分別為(2.292±1.383)、(2.881±1.234),兩組差異有統(tǒng)計(jì)學(xué)意義(P0.05);DWI-ASPECTS中評(píng)分≤6分者前后兩組分別占35.4%和71.4%,差異有統(tǒng)計(jì)學(xué)意義(P0.05)。3、遠(yuǎn)端HVS組患者入院時(shí)、10-14天NIHSS評(píng)分以及早期神經(jīng)功能恢復(fù)分值均低于無(wú)遠(yuǎn)端HVS組,兩組比較差異均有統(tǒng)計(jì)學(xué)意義(P0.05)。4、90例患者中77例行MRA檢查,42例遠(yuǎn)端HVS組患者中,動(dòng)脈閉塞者占71.4%、狹窄占28.6%,35例無(wú)遠(yuǎn)端HVS組患者中,動(dòng)脈閉塞占37.1%、狹窄占40.0%、正常占22.9%;兩組比較差異有統(tǒng)計(jì)學(xué)意義(P0.05)。5、73例非腦�；颊逿2 FLAIR序列均未出現(xiàn)HVS征。結(jié)論:1、遠(yuǎn)端HVS征象可提示血管閉塞或嚴(yán)重狹窄;2、遠(yuǎn)端HVS征象可提示存在較好的側(cè)支循環(huán);3、HVS作為一種特殊的側(cè)支循環(huán)評(píng)估方法,可作為判斷患者預(yù)后指標(biāo)之一。
[Abstract]:Objective: to investigate the imaging features and clinical prognostic value of T 2 FLAIR hyperintensity sign in patients with infarction in the middle cerebral artery (MCA). Methods: 90 patients with middle cerebral artery (MCAA) infarction with corresponding clinical manifestations were retrospectively analyzed by MRI, and hypertension was compared between distal HVS group and non-distal HVS group. General clinical data such as hyperlipidemia and the difference between the application of ASPECTS score and the NIHSS score at different stages. HVS signs were observed in 73 patients with non-cerebral infarction at the same time. Results there were 48 cases in distal HVS group and 42 cases in non-distal HVS group. There was no significant difference in general clinical data between the two groups (P < 0.05). The range of infarct lobes in distal HVS group was lower than that in non-distal HVS group. The difference between the two groups was statistically significant (P < 6). The difference between the two groups was 35.4% and 71.4%, respectively. The NIHSS score and the early recovery score of the distal HVS group were significantly lower than those of the non-distal HVS group on 10-14 days after admission, and the recovery score of early nerve function in the distal HVS group was significantly lower than that in the non-distal HVS group. The difference between the two groups was statistically significant in 77 patients with MRA and 42 patients with distal HVS. Among the 42 patients with distal HVS, 71.4 patients had arterial occlusion, and 28.6patients with stenosis had no distal HVS. Arterial occlusion was 37. 1%, stenosis was 40. 0% and normal was 22. 9.The difference between the two groups was statistically significant (P 0. 05). There was no HVS sign on T2 FLAIR sequence in 73 patients with non cerebral infarction. Conclusion the distal HVS signs may indicate occlusion or severe stenosis. The distal HVS signs can be used as a special method to evaluate collateral circulation, and can be used as a prognostic index in patients.
