Treatment Outcomes and Effects of Ethanol Sclerotherapy on Systemic Coagulation Profile of Patients with Venous Malformation

Venous malformations (VMs) and sclerotherapy may disrupt the normal systemic coagulation profile in individuals. This study investigated a correlation between the clinical efficacy of sclerotherapy in the treatment of VMs and the changes in coagulation indexes to provide data that will inform the future application of this therapy.From September 2019 to September 2020, 61 patients were enrolled in this study to receive sclerotherapy with absolute alcohol. The clinical outcomes and the coagulation profile were assessed.Sclerotherapy induced increasing fibrin (original) degradation products (FDP) and D-dimer (D-D) levels. The changes in FDP and D-D level pretreatment and posttreatment were positively correlated with treatment outcomes. Moreover, a repeated treatment with absolute alcohol may restore normal levels of FDP and D-D.Upregulation of FDP and D-D levels after sclerotherapy results in good therapeutic outcomes. Therefore, monitoring changes in FDP and D-D levels in patients with VMs undergoing sclerotherapy may reflect the effects of sclerotherapy.
