“…A simple description indicating a stenosis, if present, may be reported. Identification of stenosis can be based on grayscale and/or color flow narrowing, elevated velocity through the stenosis, and typical poststenotic waveforms. The velocity criteria for stenosis after interventions may require different criteria than native vessels 27,28 . Stents require different velocity criteria than native vessels 29–32 …”

“…The sensitivity and specificity in the detection of high-degree stenosis were 100% and 93.3%, respectively [ 4 ]. When compared with CT angiography, DUS had a specificity of 97.7%, sensitivity of 100%, a positive predictive value of 98.4%, and a negative predictive value of 100% for the detection of ICA restenosis [ 5 ]. However, criteria for diagnosis of restenosis are not well established.…”

Patient: Male, 76Final Diagnosis: Carotid in-stent restenosisSymptoms: NoneMedication: —Clinical Procedure: Carotid Doppler ultrasound • carotid percutaneous angioplastySpecialty: CardiologyObjective:Unusual clinical courseBackground:Restenosis after carotid artery stenting (CAS) is a poorly described phenomenon. Studies have reported a variable incidence ranging from 4% to 19.7% at 1 year of follow-up. Doppler Ultrasound (DUS) is now routinely used in the follow-up after CAS and endarterectomy with optimal accuracy in detecting significant restenosis, compared to digital subtraction angiography (DSA).Case Report:We reported the case of a 76-year-old patient with evidence of recurrent severe in-stent restenosis (ISR) of the left internal carotid artery (ICA). In April 2007, due to evidence at DUS of severe left ICA disease, the patient underwent CAS. In January 2009, due to DUS evidence of severe ISR, the patient underwent balloon angioplasty. In September 2011, DUS showed a severe ISR with a peak systolic velocity (PSV) of 436 cm/s; in June 2012 angiography showed a sub-expanded stent in the middle medial side with severe ISR (70%). Multiple inflations were performed and a slight residual sub-expansion of the lateral side of the stent was observed. Post-procedural DUS showed a reduction of PSV to 283 cm/s and 266 cm/s at 1-month follow-up. An increasing value (322 cm/s) was noticed at 3-month follow-up DUS, while at 6-month follow-up DUS showed an important increase to 483 cm/s. Strict follow-up was adopted because of the patient’s refusal of further treatment.Conclusions:Criteria for diagnosis of restenosis are not well established. The optimal treatment is still debated and no indications have been established, due to the lack of sufficient data. Approaches to ISR include percutaneous transluminal angioplasty, cutting-balloon angioplasty (CB-PTA), stenting, and drug-eluting balloon (DEB) angioplasty. Several studies indicate that endovascular treatment, including balloon angioplasty and (CB-PTA) alone or in conjunction with stenting, is the preferred strategy.

Color Duplex Sonography in the Detection of Internal Carotid Artery Restenosis After Carotid Endarterectomy

Abstract: Color duplex sonography can be effectively used as a primary diagnostic tool for evaluation of patients with suspected internal carotid artery restenosis after carotid endarterectomy.
