Systemic and Local Diffusion of Ethanol After Administration of Ethanol 96% Formulated in a Gel and Ethanol 98% Solution by the Percutaneous Route, in Patients With Congenital Venous Malformations:Pharmacokinetic, Pharmacodynamic and Clinical Study.
Absolute ethanol has been used "off-label" as an unmodified formulation (solution) in Congenital Venous Malformations (CVM). Despite its effectiveness, absolute ethanol appears difficult to handle because of its high diffusion capacity outside the CVM and in the blood circulation. A less diffusible ethanol-based product (ethanol gel) has been developed in order to minimize systemic and local diffusion capacities of ethanol. Therefore, the pharmacokinetic parameters and their clinical and paraclinical outcomes between ethanol gel 96% and absolute ethanol need to be carried out.

- Systemic Exposure to Ethanol With the Two Test Products: Determination of the Maximum Plasma Concentration (Cmax) [ Time Frame: Baseline visit (just before and during test product infusion procedure) ]Blood samples were performed, just before infusion, then 5 min, 10 min, 20 min, 40 min, 60 min, 90 min, and 120 min after infusion at the first site, then every 60 min onwards until ethanol levels are found under the detection limit. Cmax was estimated directly from experimental data. If all the ethanol concentrations of a patient was below the limit of quantification of the laboratory (LOQ), Cmax was reported as LOQ/2 for this patient.
