OBJECTIVE: @entity439 arising from the pericallosal artery (PA) are uncommon and challenging to treat. The aim of this study was to report our experiences of the endovascular treatment of @entity1756 . METHODS: From September 2003 to December 2013, 30 @entity1756 in 30 @entity1 were treated at our institution via an endovascular approach. Procedural data, clinical and angiographic results were retrospectively reviewed. RESULTS: Regarding immediate angiographic control, complete occlusion was achieved in 21 (70.0%) @entity1 and near-complete occlusion in 9 (30.0%). Eight procedure-related complications occurred, including intraprocedural @entity397 and early rebleeding in three each, and @entity1031 event in two. At last follow-up, 18 @entity1 were independent with a modified Rankin Scale (mRS) score of 0-2, and the other 12 were either dependent or had expired (mRS score, 3-6). Adjacent @entity1410 was found to be associated with an increased risk of poor clinical outcome. Seventeen of 23 surviving @entity1 underwent follow-up conventional angiography (mean, 16.5 months). Results showed stable occlusion in 14 (82.4%), minor recanalization in two (11.8%), and major recanalization, which required recoiling, in one (5.9%). CONCLUSION: Our experiences demonstrate that endovascular treatment for a @entity1756 is both feasible and effective. However, periprocedural rebleedings were found to occur far more often (20.0%) than is generally suspected and to be associated with preoperative contrast retention. Analysis showed existing adjacent @entity1410 is predictive of a poor clinical outcome.
