Abstract

BACKGROUND
Ethanol injection during a sclerotherapy for the treatment of arteriovenous malformation, which performed under general anesthesia, can cause significant hemodynamic changes, even cardiovascular collapse. However, guideline for adequate management of hemodynamic change or preventing detrimental complication has still not been proposed.
METHODS
Twenty-two piglets were randomly allocated to one of two groups: a 2.5 ml and a 4.0 ml ethanol. After baseline hemodynamic measurements, 2.5 ml or 4.0 ml of absolute ethanol was repeatedly administered in distal portion of renal vein with 10 minute intervals, and hemodynamic parameters were measured immediately before and after bolus injection of absolute ethanol until 10 minutes after final injection.
RESULTS
Compared with 2.5 ml group, systolic, mean and diastolic pulmonary arterial pressures (PAP) and pulmonary vascular resistance (PVR) of 4.0 ml group showed significant differences from the first bolus injection of absolute ethanol. Hemodynamic parameters of 2.5 ml group did not show the increasing or decreasing tendency during a session, whereas, in 4.0 ml group, systolic, mean and diastolic PAP and PVR showed significantly increasing tendency. However, systemic arterial blood pressure, heart rate, central venous pressure, pulmonary capillary wedge pressure, cardiac output, and systemic vascular resistance did not show increasing or decreasing tendency in both groups.
CONCLUSIONS
Based on the hemodynamic alterations observed from piglet model, the bolus injection of absolute ethanol during sclerotherapy in congenital arteriovenous malformation requires careful hemodynamic monitoring. We strongly recommend that anesthesiologist should carefully monitor the hemodynamic parameters after injection of relatively large amount of absolute ethanol.
