AIM: The study objective was to evaluate the efficacy of occlusions of large and @entity438 with microcoils using stent assistance (SA). MATERIAL AND METHODS: The study is based on analysis of treatment outcomes in 37 @entity1 with large (15-25mm) and giant (more than 25mm) @entity438 , aged 18 to 72 years, who were hospitalized at the Burdenko Neurosurgical Institute in the period between 2004 and 2014. Selection of @entity1 for endovascular treatment using SA was based on the anatomical parameters of the @entity439 and carrier vessel. The main determining factor was the index of the @entity439 body to neck size ratio. @entity439 was performed with microcoils of different configurations, including those with a biologically active coating. Self-expanding stents with both an open-cell and closed-cell design were used for SA. The results of intervention for large and @entity439 were evaluated using control angiography immediately after occlusion of the @entity439 . The condition of @entity1 with @entity439 as well as with @entity1756 in the "cold" period was evaluated using the modified Rankin scale. The condition of @entity1 in the acute period of @entity72465 was evaluated on the Hunt and Hess scale. RESULTS: The technical success (successful implantation of stents and coils with total or subtotal @entity439 ) was 94.5%. The postoperative disability was 2.7%; mortality was 2.7%. 28 @entity1 were followed up for the period of 5 to 84 months (the mean was 20 months.). In the long-term period, the total and @entity432 rate, including the results of re-operations, amounted to 90%. @entity717 was 10.7%, and mortality was 3.5%. CONCLUSION: Stent assistance enables achieving total or @entity432 of large and @entity439 in 90% of cases. In certain clinical situations, it is an alternative to other existing methods.
