Management of the treatment delay in symptomatic carotid artery stenosis

Saving time to intervention is crucial in patients with symptomatic carotid artery stenosis (SCAS). We introduced a fast-track protocol (FTP). Time frames from the onset of symptoms to intervention before and after the introduction of an FTP were analyzed. SCAS patients (403 patients/405 procedures) were evaluated according to whether surgery was performed before (group 1) or after (group 2) the introduction of the FTP. Time frames to surgery, causes of delay and frequency of recurrent events are reported. The median time delay decreased from 17 to 12 days (p<0.001), but time to ultrasound examination remained unchanged. Surgery was within 2 weeks in 41% in group 1 and in 57% in group 2 (p=0.001). Of 181 (30%) patients treated according to the FTP, 54 were operated within 7 days (median), and 80% had the intervention within 2 weeks. Time to surgery decreased significantly after the introduction of the FTP.
