title: Recurrent abrupt occlusion after transluminal angioplasty for basilar artery stenosis: case report.
abstract: OBJECTIVE
  Angioplasty for basilar artery stenosis is often complicated by recurrent abrupt vessel closure. The clinical results can be catastrophic. In this case report, we assess the effects of intra-arterial papaverine (American Regent Laboratories Inc., Shirley, NJ) on rebound occlusion.
  
  
  METHODS
  The patient presented with crescendo transient ischemic attacks from atherosclerotic narrowing of the midbasilar artery despite maximal medical treatment.
  
  
  METHODS
  Angioplasty of the midbasilar artery was performed with serial balloon inflations. The patient was treated successfully with intra-arterial papaverine and achieved a nearly full recovery, with only mild dysarthria, by the time of the 7-month follow-up examination.
  
  
  CONCLUSIONS
  Using intra-arterial papaverine, we were able to reverse the effects of this potentially life-threatening complication of basilar artery angioplasty.
