Abstract:
Objective To analyze the predictive value of CT cerebral perfusion(CTP)combined with CT angiography(CTA)for the prognosis of patients with large atherosclerotic cerebral infarction.Methods A retrospective study was performed in 98 patients with large atherosclerotic cerebral infarction who were admitted to Haian People's Hospital from January 2021 to November 2024.There were 63 males and 56 females with a mean age of(57.26±5.03)years.The mean time from onset to admission was(4.89±0.69)h.There were 20 patients with a history of smoking.After admission,CTP and CTA were performed to evaluate relative cerebral blood volume(rCBV),relative cerebral blood flow(rCBF),relative mean transit time(rMTT),relative time to peak(rTTP),and CTA score.The prognosis was evaluated according to the modified Rankin scale(mRS)3 months after intravenous thrombolysis.Then the patients were assigned to good prognosis group(0-2 points)or poor prognosis group(3-6 points).The basic data and the parameters of CTP and CTA were compared between the two groups.The receiver operating characteristic(ROC)curve was used to analyze the CTP-and CTA-related influencing factors of poor prognosis in patients with large atherosclerotic cerebral infarction.Results During 3-month follow-up,poor prognosis was found in 30 patients(25.21%).The rCBV,rCBF and CTA scores of the poor prognosis group were significantly lower than those of the good prognosis group,while the National Institutes of Health stroke scale(NIHSS)score,rMTT and rTTP at admission in the good prognosis group were significantly higher than those in the good prognosis group(P<0.05).Logistic regression equation analysis(introduction level 0.05,exclusion level 0.10)showed that NIHSS score(OR=1.622,95%CI:1.258 to 2.093),rMTT level(OR=10.757,95%CI:2.847 to 40.640)and rTTP level(OR=14.774,95%CI:3.280 to 66.558)at admission were risk factors for poor prognosis in patients with large atherosclerotic cerebral infarction(P<0.05),while CTA score(OR=0.315,95%CI:0.163 to 0.608),rCBF level(OR=0.008,95%CI:0.001 to 0.109),and rCBV level(OR=0.016,95%CI:0.002 to 0.155)were protective factors for poor prognosis in these patients(P<0.05).ROC curve analysis showed that the sensitivities of CTA score,rCBF,rCBV,rMTT,and rTTP in predicting poor prognosis in patients with large atherosclerotic cerebral infarction were 79.2%,75.0%,70.8%,58.3%,and 83.3%,respectively;the specificities were 62.2%,64.9%,70.3%,72.0%,and 70.3%,respectively;their combination had a relatively high predictive value for poor prognosis(area under the curve was 0.863).Conclusion The combination of CTP and CTA has a relatively high value in predicting the prognosis of patients with large atherosclerotic cerebral infarction.
