Se veral kinds of balloon catheter were used for embolization. External carotid c avernous fistulas and rare carotid cavernous fistulas (CCF) with minute leakage were treated by cyanoacrylate or coils. Although artery approach was applied in most cases (477 cases), vein approach showed its own advantages in some special cases.Results We found a special “bileakage sign” indicating multileakage o f TCCF, which was never mentioned before. All 482 cases were embolized successfu lly, and 405 cases maintained the patency of internal carotid artery (ICA). No t reatment related deaths occurred and the symptoms and signs of 462 cases were r elieved after embolization. Emergency embolization was needed in some conditions such as serious epistaxis, delayed or repeated subdural hematoma, and rapid vis ual impairment.Conclusion Endovascular embolization of TCCF is a safe and efficient me thod.
