Efficacy and safety analysis of dexamethasone-lipiodol emulsion in prevention of post-embolization syndrome after TACE: a retrospective analysis

Abstract

Abstract Background To investigate the efficacy and safety of dexamethasone-lipiodol emulsion in the prevention of post-embolization syndrome after TACE. Method The data of 255 patients who underwent TACE in the interventional department from June 2017 to June 2020 were collected. This is a retrospective assessment of patients who were non-randomly treated with dexamethasone in TACE. The patients were divided into two groups: TACE using lipiodol + chemotherapeutic emulsion group (TACE group, N = 133); TACE using lipiodol + dexamethasone + chemotherapeutic emulsion group (TACE + dexamethasone group, N = 122). Primary study endpoint: incidence of abdominal pain, fever, nausea and vomiting 0–72 h after TACE in both groups. Secondary study endpoints: incidence of infection after TACE in both groups. Results Incidence of post-embolization syndrome after TACE (TACE group vs TACE + dexamethasone group): abdominal pain, 55.6% versus 36.1% (P value 0.002); fever, 37.6% versus 13.1% (P value 0.000); nausea, 60.9% versus 41.0% (P value 0.001); vomiting, 48.1% versus 21.3% (P value 0.000). Incidence of infection after TACE (TACE group vs TACE + dexamethasone group): 1.5% versus 2.5% (P value 0.583). Conclusion The lipiodol + dexamethasone emulsion can significantly reduce the incidence rate of post-embolization syndrome after TACE, with exact effect and high safety.
