... following are the features a carotid scan in the post- stenting situation should address: n The location of the carotid stent: Most typically, the carotid stent is placed from CCA-to-ICA. Less com- monly, it may lie in the ICA only, CCA only, or rarely, CCA-to-ECA (Fig. 3). The reason for the placement of the stent across the bulb from CCA to ICA in most cases is for technical reasons at the time of stenting. The (typi- cally) ICA origin stenosis needs to be reliably covered by the nitinol stent (to effectively "cage" the atheroma / atheromatous debris), and this is most safely done using only one stent. ...

... stent (to effectively "cage" the atheroma / atheromatous debris), and this is most safely done using only one stent. Hence, the interventionist will typically run a 4 cm length stent from normal CCA to normal ICA, covering the diseased bulb and ICA origin. n Sampling of the stented carotid system: should be per- formed at the following locations: (Fig. 3) n 1: Mid / distal CCA before the stent ( to establish inflow velocity). n 2: Proximal stent in CCA / bulb; often there is a signifi- cant increase in velocity at this point even though there may be no perceptible change in calibre of the vessel on grey scale or colour Doppler US. This is thought to be due to compliance mismatch ...
