Abstract
Objective: We present a case in which the Angio-Seal arterial closure device (St. Jude Medical, Minnetonka, MN) and "route regaining technique" were used for emergency hemostasis after accidental intra-arterial collagen sponge deposition.
Case presentation: We treated a 66-year-old woman with a right basilar-anterior inferior cerebellar artery (BA-AICA) aneurysm through the left common femoral artery. After successful embolization, an Angio-Seal arterial closure device was inserted for hemostasis at the puncture site. However, hemostasis was incomplete and it was speculated that the collagen sponge was deployed intraarterially. We introduced another Angio-Seal device through the original puncture hole by using suture thread as a guide to locate intra-arterial objects.
Conclusion: This emergency hemostatic technique was useful for the management of unexpected bleeding stemming from intra-arterial collagen deployment. Physicians and staff should remain alert to the possibility of device-associated ischemic complications.
