In 11 of 18 cases, only PTA was performed and in seven of 18 cases, we used stents. The mean stenosis before and after PTA\/stenting was 82.8% and 22.3%, respectively. In 11 cases of PTA only, the stenotic rate decreased from 81.8% to 29.6%, while 85.0% of the stenotic rate remarkably reduced to 6.0% in seven cases of stenting.<\/jats:p>\n                  <jats:p>The 30 days morbidity and 30 days mortality rate were 5.5% and 5.5%, respectively. There was only one haemorrhagic complication (cerebellar haemorrhage) in cases of stenting, and no ischemic events during or after the procedures. Restenosis (more than 50% stenosis) occurred in four of 18 cases (22.2%) during mean follow-up period of 12 months. Two patients with VA occlusion before treatment, developed restenosis and reocclusion. Complete total occlusion seems to be a high-risk lesion and strict follow-up is required.<\/jats:p>\n                  <jats:p>In this study, PTA\/stenting for intracranial vertebrobasilar artery stenosis or occlusion is an effective treatment, but strict indications may be required because procedure-related 30 days morbidity rate was 5.5% in addition to unclear natural history.<\/jats:p>","DOI":"10.1177\/15910199040100s205","type":"journal-article","created":{"date-parts":[[2017,1,10]],"date-time":"2017-01-10T12:36:06Z","timestamp":1484051766000},"page":"21-25","source":"Crossref","is-referenced-by-count":5,"title":["Clinical Results of Percutaneous Transluminal Angioplasty and Stenting for Intracranial Vertebrobasilar Atherosclerotic Stenoses and Occlusions"],"prefix":"10.1177","volume":"10","author":[{"given":"M.","family":"Tsuura","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Terada","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Wakayama Medical University, Wakayama;
