Abstract:
Objective To observe the effectiveness and safety of endovascular stent assisted angioplasty for symptomatic intracranial arteriostenosis.Methods 4 patients with symptomatic intracranial arteriostenosis were treated with endovascular angioplasty using balloon expandable stents. Therapeutic effects were evaluated by clinical manifestations, digital subtraction angiography (DSA) and transcranial Dopple (TCD) before and after the operation. Follow up was made for 7~10 months.Results Technical success was achieved in all patients, with no complication of cerebral embolism and hemorrhage except one of transient seizure during operation. Angiographic results immediately after stenting suggested that the residual postoperation stenosis was 8%(0%~17%), with significant reduction from preoperation stenosis of 75%(70%~80.7%). No recurrent TIA and stroke occurred and no restenosis was found with serial TCD in all 4 patients during follow up of 7~10 months.Conclusions Endovascular stenting is a safe and effective therapeutic tool for symptomatic intracranial arteriostenosis.
