0.035-inch Non-Detachable Fibered CoilでInternal Trappingを施行したCarotid Blowout Syndrome：症例報告

Abstract

●Abstract● Objective: We report a case of carotid blowout syndrome (CBS) treated by internal trapping using 0.035-inch non-detachable fibered coils. Case presentation: A 54-year-old man presented with massive hemorrhage from a skin defect in the neck 12 years after radical neck dissection and chemoradiation therapy for a right submandibular gland adenocarcinoma. Emergency tracheostomy was performed and gauze compression resulted in hemostasis. CT angiography revealed a pseudoaneurysm of the right cervical carotid artery. In addition, the right external carotid artery was occluded. Under the diagnosis of impending CBS, we performed endovascular treatment on an emergency basis. Since the patient tolerated temporary balloon occlusion of the right common carotid artery, internal trapping using 0.035-inch non-detachable coils was performed under proximal flow control. The right carotid artery was successfully occluded without any neurological deficit. Conclusion: Internal trapping using 0.035-inch non-detachable fibered coils is an effective treatment for CBS. ●Key Words● carotid blowout syndrome, internal trapping, 0.035-inch non-detachable fibered coil
