Abstract:
Objective:To investigate the value of color Doppler ultrasound in the evaluation of carotid artery restenosis after ca-rotid artery stenting (CAS) and carotid endarterectomy (CEA) .Methods :A total of 53 patients with 62 carotid artery stenosis diagnosed by digital subtraction angiography (DSA) were enrolled .All of them underwent CAS and CEA .The postoperative and preoperative ultrasound datum including the minimum luminal diameter ,the peak systolic velocity (PSV )of the internal ca-rotid artery (ICA) and common carotid artery (CCA) ,end diastolic velocity (EDV) of ICA were retrospectively analyzed . Results:A total of 52 arteries were normal or had <50% restenosis ,while 10 arteries had ≥50% restenosis after the treat-ment .Compared with those before treatment ,the minimum luminal diameter was significantly wider ,and PSVICA decreased significantly in patients with <50% restenosis(P<0 .01) ,whereas the minimum luminal diameter and PSVICA were not sig-nificantly changed in patients with≥50% restenosis(P>0 .05) .PSVICA ,EDVICA and PSVICA/PSVCCA in patients with≥50% restenosis significantly increased compared with that in patients with <50% restenosis(P<0 .01) .PSVICA/PSVCCA≥2 was set as the cut-off point ,the sensitivity and specificity for detecting ≥50% restenosis were 80 .0% and 98 .1% respective-ly .Conclusions :Color Doppler ultrasound can effectively evaluate carotid artery restenosis after CAS or CEA .
