Since 1991 the decision to treat a symptomatic patient who has suffered a TIA or minor stroke has largely been guided by the results of the North American Symptomatic Carotid Endarterectomy Trial (NASCET)6 and the European Carotid Surgery Trial (ECST).7 These two trials used angi- Duplex Velocity Criteria for ICA Stenosis—Hoe-Chin Chua et al who do not require it.

The management of atherosclerotic carotid occlusive disease for stroke prevention has entered a time of dramatic change. Improvements in medical management have begun to challenge traditional interventional approaches to asymptomatic carotid stenosis. Simultaneously, carotid artery stenting (CAS) has emerged as an alternative to carotid endarterectomy (CE). Finally, multiple factors beyond

These changes persist during long-term follow-up and across all grades of in-stent restenosis after CAS. The proposed new velocity criteria accurately define residual stenosis >or =20%, in-stent restenosis >or =50%, and high-grade in-stent restenosis > or =80% in the stented carotid artery. There has been an ongoing debate regarding which duplex ultrasound (DUS) criteria to use to determine the rate of in-stent restenosis. This prospective study revisits DUS criteria for determining the rate of in-stent restenosis. In analyzing a subset of 12 patients (pilot study) who had both completion carotid angiography and DUS within 30 days, 10 patients with normal post-stenting carotid angiography (< 30% residual stenosis) had peak systolic velocities (PSVs) of the stented internal The optimal DUS velocity criteria for in-stent restenosis of >or=30%, >or=50%, and >or=80% were the PSVs of 154, 224, and 325 cm/s, respectively.

Introduction The identification of carotid artery stenosis is the most common indication for cerebrovascular ultrasound. The majority of stenotic lesions occur in the proximal internal carotid artery (ICA); however, other sites of involvement in the carotid system may or may not contribute to significant neurologic events.
Although it may be true that intimal hyperplasia causing early restenosis in patched carotid arteries is less compliant and, The widely referenced Society for Radiologists in Ultrasound Consensus Statement on carotid duplex ultrasound (CDUS) imaging indicates that an ICA peak systolic velocity (PSV) ≥230 cm/s corresponds to a ≥70% ICA stenosis, leading to the potential conclusion that asymptomatic patients with an ICA PSV ≥230 cm/s would benefit from CEA. Various duplex criteria have been used to predict hemodynamically significant carotid artery stenosis.
