RESUMO
Objective To summarize the radiographic characteristic and endovascular interventional technique in patients with intracranial vertibrobasil dissectimng aneurysm.Methods Totally 30 patients of intracranial vertibrobasil dissectimng aneurysm were embolized by endovascular therapy,4 with stent implantation technique,26 with stent assisted coiling technique.Results Patency of parent artery was restored in 25 cases(83.3%),and except 1 case(3.3%) of postoperative intracerebral hemorrhage,no other complications occurred.All patients were followed up from 5 months to 34 months(average 11.2).All cases recovered well.No case died in the cohort.Conclusion Intracranial vertibrobasil dissectimng aneurysm has following angiographic features: string sign,pearl and string sign,and double lumen sign.Therapeutic strategies depend on clinical symptoms,the location,configuration of the dissection,and the relationship of vital branches around.The results suggested that embolization of intracranial vertibrobasil dissectimng aneurysm with coils is minimally invasive,safe,effective and reliable.
