Abstract: Objective To evaluate the early management of intracranial vertebral dissecting anourysms. Method The raptured intracrunial verterbral dissecting aneurysms have been treated early since August 2005 according to their specific configuration by three endovascular techniques. 6 aneurysms were treated by stent-assisted coiling;4 aneurysras were treated by double stents technique;4 anourysms were treated by anemysm and parent artery coiling. Bloody cerebrospinal fluid was drained as early as possible after endovascular treatment, together with calcium channel blockers to prevent cerebral vasospasm. Results There was no embolic or bleeding complication during the operations. 13 patients recovered well, except that one patient who harbored Hunt&Hess Ⅴ died due to initiated severe brain damage. Follow-up 16 months, there is no rebleeding. Angiographic follow-up,6 anerysms treated by stent-assisted coiling except one who had partial recanahzation did not recur. In 4 aneurysms treated by double stents technique, the fusiform ectasia portion of two aneurysms disappeared and remarkably diminished in another two aneurysms. 3 aneurysms treated by aneurysm and parent artery coiling have no recanalization. Conclusions Early endovascular treatment of ruptured vertebral dissecing uneurysms is safe and effective. According to morphologic characteristics of aneurysm,it is better to choose a suitable technique such as stent-assisted coiling.
