Clinical Research of Combined Arteriovenous Approach Embolization on Complex Carotid-Cavernous Fistulas

Abstract

The objective of this study was to observe the curative effect of combined arteriovenous approach embolization on complex carotid-cavernous fistulas. The clinical data of 13 patients with complex carotid-cavernous fistulas treated with combined arteriovenous approach embolization in our department between January 2017 and January 2020 were analyzed retrospectively. All 13 patients received the combined arteriovenous approach embolization with coil combined with Onyx glue. The intraoperative angiography immediately showed that the fistula could be completely blocked, and the carotid artery was/got unobstructed. The patients had no clinical symptoms recurring during a follow-up period of 3-18 months, on average $9.1\pm 6.3$ months. A combined arteriovenous approach embolization on complex carotid-cavernous fistulas is safe and effective since it can improve the occlusion rate and reduce the relapse rate.
