OBJECTIVE: To study the feasibility, safety and validity of percutaneous angioplasty and stenting (PTAS) for symptomatic @entity731 of basilar artery. METHODS: The results of treatment and follow-up of 40 cases with symptomatic @entity731 of basilar artery performed PTAS from August 2003 to December 2009 were studied retrospectively, who had either recurrent transient @entity63 attacks (TIAs) or obvious @entity63 symptoms and resistant to medical therapy. RESULTS: PTAS were successfully performed in all the 40 cases and the post-operative average residual stenosis descended to 14%    11% from pre-operative 82%    14%. After operation the @entity1 were administrated with antiplatelet drugs. After procedure the clinic symptoms and signs of @entity63 were improved obviously in 38 cases and deteriorated in 2 cases whose CT scanning showed that the range of @entity1188 in brain stem enlarged. The symptoms improved after treatment but 2 @entity1 had @entity51 . No @entity548 occurred in the group. During the follow-up for 2 months to 7 years, transcranial doppler ultrasonography in 26 cases demonstrated the blood flow was faster than normal in 2 cases, and digital subtraction angiography (DSA) in 6 cases showed @entity256 in 1 case. The second stent was implanted because of the symptomatic restenosis. In another case the follow-up DSA showed @entity432 in-stent but there was no @entity63 of post circulation because the generation of anastomoses. CONCLUSIONS: PTAS is a feasible, safe and effective therapeutic method for the @entity1 with symptomatic @entity731 of basilar artery. Further study in large number of @entity1 is needed for long-term outcome.
