动静脉畸形患者无水乙醇栓塞后发生循环抑制和溶血反应1例报告

Cardiovascular depression and intravascular hemolysis secondary to ethanol injection for arteriovenous malformation

无水乙醇在动静脉畸形硬化剂治疗中最为有效,但在临床使用过程中的风险也较大。本文报告1例无水乙醇治疗后出现血红蛋白尿和循环抑制的患者,并对其治疗过程进行总结和讨论,提出谨慎选择无水乙醇治疗剂量和加强实时监测,以提高治疗安全性。

Ethanol is the only liquid embolization agent which can cure arteriovenous malformation. Complications of ethanol embolization are not rare including local tissue injury, intravascular hemolysis and cardiovascular depression even collapse, etc. This report presented a case of long time cardiovascular depression and intravascular hemolysis secondary to ethanol embolotherapy of right ear. In order to avoid the fatal complications that are associated with ethanol sclerotherapy, anesthesiologists should consider the use of continuously invasive hemodynamic monitoring while surgeons should carefully choose the dose of ethanol.
