The Potential of Creatinine-Fibrinogen Ratio Levels as an Indicator of Severe Placenta Abruptio: A Retrospective Case Control Study.

PURPOSE

To compare the relationship between the severity of placenta abruptio and creatinine-fibrinogen ratio (CFR).

PATIENTS AND METHODS

Patients with mild and severe placental abruption were separated. Patients with ≥1 maternal complications (eg, DIC, hypovolemic shock, blood transfusion, hysterectomy, acute kidney injury, death) were classified as severe placental abruption, while those without were classified as mild. The two groups were compared in terms of hematological parameters and CFR levels at the time of hospital admission.

RESULTS

In the study of patients classified by the severity of placental abruption, there were 107 individuals in the mild group and 51 in the severe group. The severe group had elevated creatinine and diminished fibrinogen levels (p = 0.001 and p < 0.001, respectively). The CFR levels of the severe group was significantly higher (p < 0.001). CFR levels were used for ROC analysis to differentiate mild and severe abruptio placenta. CFR had an AUC value of 0.730 (p < 0.001). CFR cut-off values were 0.1381 with 64.7% sensitivity and 76.6% specificity. In this analysis, logistic regression revealed significantly greater CFR (OR 1.064, 95% CI: 1.010-1.220; p = 0.019).

CONCLUSION

CFR appears to be an effective indicator for predicting severity of placenta abruptio in pregnant women with placental abruption.
