【摘要】 目的:分析顱內動脈瘤栓塞術后并發腦血栓與D-二聚體(D-D)的相關性。方法:選取2018年10月-2019年11月本院60例顱內動脈瘤栓塞術后并發腦血栓患者為A組,60例顱內動脈瘤栓塞術后未并發腦血栓患者為B組,另選取同時期60例健康體檢者為C組。比較三組的血小板計數(PLT)、凝血酶原時間(PT)、活化部分凝血活酶時間(APTT)、凝血酶時間(TT)、纖維蛋白原(Fg)及D-D水平;比較A、B組術后1、3 d的PLT、PT、APTT、TT、Fg及D-D水平;分析顱內動脈瘤栓塞術后并發腦血栓與D-D的相關性及D-D在術后并發腦血栓中的預測價值。結果:A組PLT、PT、APTT、TT、Fg及D-D水平均高于B組及C組,且B組各指標均高于C組(P<0.05);A組術后1、3 d的PLT、PT、APTT、TT、Fg及D-D水平均高于B組(P<0.05);術后1 d的D-D水平與顱內動脈瘤栓塞術后并發腦血栓呈正相關(r=0.873,P<0.05);D-D預測術后腦血栓發生的ROC曲線下面積為0.802(P=0.005),截斷點為1.72 μg/mL,靈敏度為83.30%,特異度為62.40%。結論:顱內動脈瘤栓塞術后并發腦血栓與D-D密切相關,D-D對顱內動脈瘤栓塞術后并發腦血栓的預測價值較高。

[Abstract] Objective: To analyze the correlation between the cerebral thrombosis and D-dimer (D-D) after intracranial aneurysm embolization. Method: A total of 60 patients complicated with cerebral thrombus after intracranial aneurysm embolization in our hospital from October 2018 to November 2019 were selected as group A, 60 patients without complicated cerebral thrombus after intracranial aneurysm embolization were selected as group B, and another 60 healthy patients during the same period were selected as group C. Platelet count (PLT), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fg) and D-D levels of the three groups were compared. PLT, PT, APTT, TT, Fg and D-D levels of group A and B were compared on 1 d and
3 d after surgery. The correlation between D-D and cerebral thrombus after intracranial aneurysm embolization and the predictive value of D-D in postoperative cerebral thrombus were analyzed. Result: The levels of PLT, PT, APTT, TT, Fg and D-D in group A were higher than those in group B and C, and all indicators in group B were higher than those in group C (P<0.05). The levels of PLT, PT, APTT, TT, Fg and D-D on 1 d and 3 d after surgery in group A were higher than those in group B (P<0.05). The D-D level on 1 d after surgery was positively correlated with cerebral thromboembolism after intracranial aneurysm embolization (r=0.873, P<0.05). The area under the ROC curve predicted by D-D was 0.802 (P=0.005), the cut-off point was 1.72 μg/mL, the sensitivity was 83.30% and the specificity was 62.40%. Conclusion: The correlation between the cerebral thrombosis and D-D after intracranial aneurysm embolization is closed,and D-D has a high predictive value for cerebral thrombus after intracranial aneurysm embolization.
本研究中顱內動脈瘤栓塞術后并發腦血栓患者的PLT、PT、APTT、TT、Fg、D-D水平均高于術后未腦血栓患者及健康體檢者,術后未腦血栓患者各指標則高于健康體檢者,Pearson相關性分析顯示,D-D與顱內動脈瘤栓塞術后并發腦血栓呈正相關(r=0.873,P<0.05),D-D預測術后腦血栓發生的ROC曲線下面積為0.802,截斷點為1.72 μg/mL,靈敏度與特異度分別為83.30%及62.40%,因此肯定了D-D與本類腦血管疾病患者術后并發腦血栓的關系,也肯定了D-D對于本類手術患者腦血栓發生危險的預測價值。分析原因,筆者認為D-D可有效反應血液高凝狀態,而顱內動脈瘤栓塞術患者術后D-D表達水平升高,說明患者存在繼發性的纖維蛋白溶解亢進,這是血栓形成的重要原因,且水平越高則說明危險程度越高[14-16]。同時提示對于本類手術患者進行D-D監測與及早干預的必要性,以達到防控腦血栓形成及改善預后的目的[17-19]。本研究結果顯示,并發腦血栓患者的術后的檢測結果升高趨勢,而未發生者為降低趨勢,提示對于上述指標術后變化規律的監測意義較高,對于出現持續升高的患者應重點進行防控。另外,顱內動脈瘤患者因手術治療及機體不良應激等因素也導致凝血功能呈現一定程度的亢進,主要與介入治療中的器材及操作等導致的凝血活性觸發情況有關,表現出D-D升高的狀態,而升高幅度較大者的血栓發生危險程度越高[20-22]。
綜上所述,顱內動脈瘤栓塞術后并發腦血栓與D-D密切相關,D-D對顱內動脈瘤栓塞術后并發腦血栓的預測價值較高。
