[Spontaneous arteriovenous XXXX of the external carotid artery treated by a detachable balloon--a case report].

Spontaneous @entity7838 ( @entity7838 ) of the external carotid system is very rare. We successfully treated such a case by the detachable balloon method. The @entity1 , a 2-year-and-9-month-old female who has no history of @entity130 had a pulsating mass at her right retroauricular region six months after birth. On admission to our clinic she was neurologically free except the pulsating mass (2 X 3 cm) with bruit and thrill. Selective right external carotid angiography revealed a high-flow simple @entity7838 from internal maxillary artery to jugular vein. The normal blood flow of both the external and internal carotid system was decreased. Under local anesthesia, non-detachable balloon catheter was inserted to the internal maxillary artery by the transfemoral approach and inflated at the proximal side of the orifice of @entity7838 until the vascular murmur in the @entity135 disappeared. The balloon catheter was then exchanged with a detachable balloon catheter (Debrun, No. 9) which was inflated by @entity1346 (0.4 ml), and was detached successfully. Follow-up angiography 1 year after the treatment revealed no recurrence of the @entity292 and almost branches of external carotid artery such as middle meningeal artery, occipital artery, superficial temporal artery and facial artery were clearly seen.
