Embolization of dural arteriovenous fistula during twin pregnancy - A case report and literature review.

We encountered a case of cavernous sinus DAVF during a twin pregnancy. This case suggests that hemodynamic shift due to pregnancy has potential to cause higher shunt flow in an arteriovenous fistula. The timing of treatment should be determined in consideration of the hemodynamic change in the course of pregnancy. If X-ray exposures and iodine contrast media are appropriately managed, endovascular intervention is one treatment option, even during pregnancy.
