Purpose:
To observe and analyze the abnormal effect of ethanol sclerotherapy for arteriovenous malformations on hemodynamics.
Methods:
Twelve cases of arteriovenous malformations who received absolute ethanol sclerotherapy were chosen. The heart rate, blood pressure, SPO₂ and ETCO₂ at different times were recorded and analyzed.
Results:
Obvious change of HR and BP were observed before and after injection of absolute ethanol into arteriovenous malformation. HR changed from preoperational (82.8 ± 11.5) bpm to the highest (98.8 ± 13.5) bpm, While BP changed from preoperational (98.6 ± 6.5) mmHg/(53.1 ± 3.3) mmHg to the lowest (73.7 ± 6.3) mmHg/(39.3 ± 4.8) mmHg. No change of SPO₂ and PETCO₂ was observed.
Conclusions:
Absolute ethanol sclerotherapy for arteriovenous malformation can result in obvious S-shaped change of HR and BP. The actual cause is unknown, but we should pay more attention to the abnormal changes and manage accordingly.
