| Abstract | BACKGROUND AND PURPOSE: Intracranial angioplasty and stenting are therapeutic options for patients with symptomatic intracranial arterial stenoses intractable to medical therapy. However, the long-term safety and clinical efficacy of these techniques are unknown. We sought to assess the long-term outcome and efficacy of these techniques. METHODS: Procedural data and 30-day outcomes were collected from patients treated with coronary balloons and stents for >/=70% atherostenoses. Clinical and radiographic follow-up data were obtained at 30 days, 6 months, 12 months, and yearly thereafter. RESULTS: Fifty-three patients (median age, 67 years; interquartile range [IQR], 58.75 to 75 years) with 69 arterial lesions were treated during a 7-year period. The technical success rate was 98.6% (68/69), with a reduction of the median percent stenosis from 85% (IQR, 70% to 95%) to 0% (IQR, 0% to 26%). In 76.8% (53/69) of the procedures, a stent was implanted. The 30-day death/stroke rate was 10.1% (7/69) with 1 death, and within a median follow-up of 24 months (IQR, 10.25 to 36.5 months), the transient ischemic attack or stroke rate reached 5.8% (4/69). Restenosis rate at 1 year was 15.9% (11/69) and was symptomatic in 18.2% (2/11). The restenosis rate was 50% for angioplasty (8/16) and 7.5% (4/53) for stenting (hazard ratio=5.02; 95% CI, 1.22 to 20.68). Factors associated with restenosis were vessel size <2.5 mm (hazard ratio=4.78; 95% CI, 1.35 to 16.93) and interventions performed in the setting of an acute stroke (hazard ratio=6.36; 95% CI, 1.78 to 22.56). CONCLUSIONS: Intracranial stenting may reduce the rate of recurrent ischemia in patients in whom medical therapy is unsuccessful and is probably more durable than angioplasty alone. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
