Objectives: To report on early and mid-term outcomes of carotid artery stenting (CAS) in patients with angiographic string sign (SS). Background: Little is known about the prognosis of patients with carotid SS treated by CAS. Methods: We retrospectively evaluated early and mid-term outcomes, together with ultrasound findings, in patients with SS treated by CAS at our institution. Results: Of 308 CAS procedures, SS was diagnosed in 6.2% (19 patients, 58% symptomatic). Carotid stent implantation was successful in 18 patients (success rate 95%). There were no peri-procedural adverse events. One patient suffered from a transient ischemic attack during hospitalization and died of pneumonia. All remaining patients completed a 30-day follow-up, and no complications were reported (asymptomatic restenosis was diagnosed in 1 patient and successfully redilated). Six patients died of causes unrelated to CAS (pneumonia, decompensated heart failure, and contralateral stroke) before completing a 6-month follow-up. However, these patients presented with more pronounced, unfavorable clinical and angiographic characteristics compared to the rest of the patients. Conclusions: We suggest that CAS might be performed with acceptable procedural risk in patients presenting with SS, which is unsuitable for surgery. However, patients%26apos; clinical and angiographic characteristics must be carefully evaluated when considering interventional therapy, regardless of the favorable procedural outcomes.
