Objective To study the endovascular management of intradural hemorrhage spontaneous vertebral artery dissection (SVAD) with guglielmi detachable coils (GDCs) and mechanical coils,and explore its therapeutic effect.Methods Four patients with defined intradural hemorrhage SVAD by DSA,admitted to our hospital from January 2008 to December 2011,were chosen in our study;SVAD in 4 patients located in the proximate posterior inferior cerebellar artery.Endovascular management was adopted by evaluating their medical imaging and clinical data.The aneurysms were filled with GDCs,and the parent arteries were performed embolism with mechanical coils.Results No patient died; no aneurysms ruptured and no other severity complications happened during operation.Postoperative angiography showed complete occlusion of SVAD in 4 cases.No rehemorrhagia or ischemia happened during the 6-36 months of follow up.Conclusion Endovascular intervention with GDCs and mechanical coils is a safe and efficacious method for intradural hemorrhage SVAD,which can not only decrease the ratio ofrebleeding,but decrease the surgery cost as well.
