title: Carotid endarterectomy after ischemic stroke--is there a justification for delayed surgery?
abstract: OBJECTIVE
  To assess the relationship between outcome of carotid surgery and wait after ischemic stroke.
  
  
  METHODS
  We retrospectively analysed data from patients undergoing carotid endarterectomy after ischemic stroke. We investigated the time interval between the event and endarterectomy in relation to surgical results and complications.
  
  
  RESULTS
  Between January 2000 and December 2003, 104 patients were scheduled to undergo carotid endarterectomy after a recent stroke. Endarterectomy was performed within 6 h in seven patients (6.7%); within 4 weeks in 29 (27.9%); 4 weeks or more in 62 (59.6%) and six (5.8%) patients received no further therapy. Perioperative complications among patients treated within 4 weeks were 3.4% and were comparable to those treated after 4 weeks (4.8%). However, more than 12% of the patients awaiting operation experienced a new cerebrovascular event (ischemic stroke or carotid occlusion), most of them occurred in the 3rd or 4th week after the initial event.
  
  
  CONCLUSIONS
  Our data indicates, that carotid endarterectomy can be performed with a comparable risk within a short delay after stroke. In addition severe cerebrovascular events occurring within the waiting period may be avoided.
