超声联合血FAR对卵巢肿瘤切除术后下肢深静脉血栓形成的早期预测价值OA

Objective:To investigate the early predictive value of ultrasound parameters combined with fibrinogen/albumin ratio(FAR)for lower extremity deep venous thrombosis(LEDVT)after ovarian tumor resection.Methods:A total of 84 patients underwent ovarian tumor resection at our hospital from June 2021 to June 2024 were collected.According to the results of lower extremity deep vein angiography,they were divided into normal group and thrombus group.The coagulation indexes(D-dimer(D-D),prothrombin time(PT),etc.),vascular ultrasound parameters(peak systolic blood flow velocity(PSV),end diastolic blood flow velocity(EDV)and mean blood flow velocity(MFV))and FAR value before and after surgery were compared between the two groups.Receiver operating characteristic curve was used to analyze the predictive efficiency of ultrasound parameters combined with FAR on LEDVT after ovarian tumor resection.Pearson correlation analysis was adopted to analyze the correla-tion between ultrasound parameters,FAR and coagulation indexes.Results:The PT in thrombus group after surgery was short-er than that in normal group,and the D-D level before and after surgery was higher than that in normal group(P＜0.05).The FAR in thrombus group was higher(P＜0.05),while the PSV,EDV and MFV were lower than those in normal group(P＜0.05).Ultrasound parameters combined with FAR had the highest predictive efficiency on LEDVT after ovarian tumor resection,and the Youden index,area under the curve,sensitivity and specificity were 0.680,0.905,95.45%and 72.58%respectively.PSV in thrombus group was positively correlated with postoperative PT,and negatively correlated with postoperative D-D(P＜0.05),and FAR value was positively correlated with postoperative D-D(P＜0.05).Conclusion:Ultrasound parameters combined with FAR has high predictive efficiency on LEDVT after ovarian tumor resection,and can be used as an effective auxiliary method for early screening and risk stratification.
