ABSTRACT
Objective To preliminary evaluate the mid-term clinical effect of endovascular repair in treating spontaneous extracranial internal carotid artery (ICA) dissection,and to observe the patency of stent.Methods The clinical data and imaging materials of 6 patients with spontaneous extracranial ICA dissection,who were treated with endovascular repair during the period from March 2012 to December 2012,were retrospectively analyzed.The U.S.National Institute of Heahh Stroke Scale (NIHSS) scores were determined before and after endovascular repair,and the postoperative stent patency condition was assessed,the results were analyzed.Results A total of 6 patients,including 4 males and 2 females with a median age of 50 years old (40.75-54.75 years old),received endovascular repair therapy.The median interval from the onset of disease to accept endovascular treatment was 10 days (one week-3 months).After the implantation of stent,the blood flow in the true lumen returned to normal immediately,although part of the false lumen was still filled with contrast agent.Embolism of retinal artery occurred in one patient during the operation,no death occurred.The median follow-up time was 54.4 months (49.7-57.9 months).The NIHSS score determined at the last follow-up visit was not significantly different from the preoperative one (P=0.102).Imaging reexamination revealed that the false lumen at the ICA stent segment disappeared in all 6 patients,and no obvious in-stent stenotic changes were observed.Conclusion Endovascular therapy of selected symptomatic extracranial carotid artery dissection with bare stents can effectively prevent the recurrence of clinical symptoms and promote ICA remodeling with excellent mid-term patency.
