Carotid artery stenting is a new treatment for carotid atherosclerotic stenosis, which has developed rapidly in recent years, but its long-term efficacy and the occurrence of complications require further follow-up. Dr. Ling of the Royal Perth Hospital, Australia, published in the June 2008 issue of the American Journal of Vascular Surgery (Ling AJ, Mwipatayi P, Gandhi T, Sieunarine K. Stenting for carotid artery stenosis: fractures, proposed etiology and the need for surveillance. etiology and the need for surveillance. J Vasc Surg. 2008 Jun;47(6):1220-6) published a paper stating that one should be alert for carotid stent dissection. The authors retrospectively analyzed all cases of carotid artery stenting performed between March 2004 and December 2006 by a single operator. To ensure the quality of measurements and evaluations, two vascular surgeons and a radiologist each read films separately to determine the presence of stent breaks. At a mean follow-up of 15 months, the incidence of carotid stent breaks was found to be 29.2% (14 out of 48 stents broke), with restenosis occurring in 21% of those who broke. A significant correlation was found between vascular calcification and stent fracture. Although the sample in this study was small, it confirms that carotid stent breaks do exist, and more importantly, some breaks can lead to adverse outcomes such as in stenosis. Therefore, the authors suggest that carotid stenting should be followed by routine ultrasound Doppler examination of patency and stenosis, in addition to routine plain neck radiographs to clarify the presence of stent breaks.
