Abstract:
Objective To evaluate the feasibility, safety and efficacy of Solitaire stent placement for treatment of complex intracranial atherosclerotic stenosis. Methods We retrospectively reviewed the clinical data of 18 patients who underwent Solitaire stent placement for symptomatic intracranial arterial stenoses in our department between November 2011 and June 2012, with focus on the stenosis morphology, condition of the diseased blood vessels, surgical success rate, and perioperative complications. We also summarized the early outcomes and imaging findings during follow-up. Results The patients included 8 males and 10 females, with a mean age of 66. 55 + 9. 84 years old. Mori typing results were 5 A, 8 B, and 5 C types; LMA typing results were good in 2, moderate tortuosity in 12, severe tortuosity in 4 cases. All the patients received successful Solitaire stent implantation. The average stenosis rate was reduced from (74 + 12. 5)% to (10 + 5. 5)% after the procedure. There was only one patient (5. 6%) had post-operative complication (cerebral infarction of the target vessel territory), who had temporal symptom and recovered well at follow-up. Clinical follow-up was available for 18 patients, with a mean of 6.2+ 1. 4 months; and no patients experienced any ischemic episodes. Fifteen patients had DSA or CTA follow-up for a mean of 7. 8 + 2. 6 months. There were 3 in-stent restenosis (20%) cases and one of them wassymptomatic with transient ischemic attack. Conclusion Solitaire stent placement is feasible, safe and effective for complex symptomatic intracranial artery stenosis, with definite short-term effectiveness, and the long-term effect warrants further investigation.
