Analysis of risk factors for postoperative thrombosis in patients with hematological diseases undergoing PICC surgery

This study analyzes the prognostic factors of thrombosis in patients with hematological diseases after peripherally inserted central catheter (PICC) surgery. We conducted a retrospective analysis of 223 patients with hematological diseases who underwent PICC catheterization between January 2017 and June 2021. These patients were categorized into the thrombotic group and non-thrombotic group based on the occurrence of thrombosis following PICC catheterization. Subsequently, we identified influencing factors for thrombosis in patients with hematological diseases after PICC catheterization using univariate and multivariate logistic regression. Furthermore, we drew the ROC curve and calculated the AUC value to obtain the ideal critical value for predicting thrombosis risk in these patients. After PICC catheterization in 223 patients with hematological tumors, 107 cases developed thrombosis. The univariate analysis revealed significant differences in age, catheter placement, catheter-related complications (infection), the proportion of underlying diseases, and coagulation-related indicators between the 2 groups. Furthermore, the multivariate analysis demonstrated that catheter infection, diabetes, history of thrombosis, fibrinogen degradation products (FDP), antithrombin III (AT-III) and D-dimer were all independent factors of thrombosis in patients with hematological diseases after PICC. The AUC areas of the working characteristic curves of FDP, AT-III, and D-dimer in predicting post PICC thrombosis in patients with hematological diseases were 0.744, 0.651, and 0.595, respectively. Hematological diseases patients with catheter infection, diabetes, history of thrombosis, FDP > 3.24 mg/L, AT-III < 93%, or D-dimer > 2.41 µg/mL are prone to thrombosis after PICC surgery.
