Migration of n-BCA glue as a complication of venous malformation treatment in children

Preoperative n-butyl cyanoacrylate (n-BCA) embolization of venous malformations facilitates surgical resection. Although embolization is generally well-tolerated, central venous n-BCA migration can occur. The purpose of this article is to describe 3 cases of glue migration requiring glue embolectomy. Strategies for prevention and treatment of glue migration during embolization of venous malformations are reviewed.
