title: Endovascular treatment of carotid artery occlusion in progressive stroke syndromes: technical note.
abstract: OBJECTIVE
  We describe two patients, with progressing neurological deficits, who showed improvement after revascularization of their carotid arteries using stents.
  
  
  METHODS
  One patient presented clinically with the symptoms of a middle cerebral artery territory stroke. Angiography demonstrated total occlusion of the right internal carotid artery (ICA), with evidence of clot from the origin of the ICA to the middle cerebral artery trifurcation. The second patient presented with bilateral ICA occlusions and evidence of a progressing left hemispheric deficit; she was receiving therapeutic levels of heparin at the time of deterioration of her condition.
  
  
  METHODS
  Thrombolysis and stenting successfully recanalized the occluded vessels, and the deficits of the first patient were reversed. With the second patient, a dissected carotid loop was encountered. Straightening of the loop with a wire and stenting of the carotid artery using two stents allowed revascularization of the left hemisphere and resolution of most of the deficits of this patient.
  
  
  CONCLUSIONS
  This report demonstrates the technical feasibility of placing stents in high-risk patients with carotid artery occlusions from either dissection or atherosclerosis. Both patients sustained much smaller infarctions than would have been expected if the carotid artery territory had been infarcted. We report on the technical feasibility of reopening acutely closed ICAs by using endovascular methods.
