AIMS: To evaluate the safety and efficacy of endovascular intervention in the treatment of ruptured vertebrobasilar dissecting aneurysms (VBDAs) with the aim of developing endovascular treatment standards for this disorder. MATERIALS AND METHODS: The results of 40 consecutive patients with ruptured VBDAs, who were treated with internal trapping (n = 7), stent(s)-assisted coiling (n = 26), and solely stenting (n = 7) from January 2010 to June 2014, were retrospectively reviewed and analyzed. RESULTS: A treatment protocol for the ruptured VBDAs was created and proved to be effective. All 7 patients treated with internal trapping had satisfactory outcomes; none had treatment-related complications, rebleeding, or recanalization after treatment. Of the 26 patients treated with stent-assisted coiling, one patient suffered from an acute in-stent thrombosis during the operation, one had a small cerebral cortical infarction, one had rebleeding, and one had recanalization of his obliterated aneurysm after surgery. Of the seven patients treated solely with stenting, one patient had recanalization and two patients suffered rebleeding, of whom one patient died. CONCLUSIONS: The treatment protocol for ruptured VBDAs proposed in this study proved to be a simple and effective method in selecting the requisite treatment. If a proper endovascular strategy is in place, an effective treatment outcome for ruptured VBDAs can be obtained.
