“…[10][11][12][13][14] It appears that higher PSVs are likely needed to stratify stenosis in these vessels. There is no consensus as to why stented internal carotid, renal, and now SMAs have higher than expected duplex scan-determined PSVs when compared to angiographic images.…”

“…It appears higher velocity levels are required for identification of stenosis in stented internal carotid arteries and renal arteries then would be expected from criteria developed for identifying stenosis in native internal carotid and renal arteries. [10][11][12][13][14][15] A similar situation may exist for the mesenteric vessels. The purpose of this study was to determine whether traditional duplex scan criteria for high-grade native artery mesenteric artery stenosis can be extrapolated to stented SMAs.…”

SMA stenting provides good anatomic results and significantly reduces measured pressure gradients. Duplex scans measured SMA PSVs are reduced post-stent placement but despite good angiographic results remain above criteria predicting high-grade native artery SMA stenosis. Duplex scan criteria developed to identify high-grade native artery SMA stenosis accurately predict high-grade native artery SMA stenosis but overestimate stenosis in stented SMAs. New duplex scan criteria are required to predict high-grade stenosis in stented SMAs.

Evaluation of various image reconstruction parameters in lower extremity stents using multidetector-row CT angiography: initial findings

et al. 2006

Image quality, visible lumen and patency of lower limb stents was assessed by multidetector-row computed tomography (MDCT) angiography using various reconstruction parameters and the results compared with conventional angiography. Fourteen patients (25 stents) were evaluated. From MDCT datasets, axial and coronal oblique reformations were reconstructed using differing reconstruction parameters (slice thickness, kernel, views). Artifacts and image quality were assessed using a five-degree scale (1=excellent, 5=poor). Visible stent diameter was measured. Stenosis severity was compared with calibrated catheter angiography. The image quality of medium and sharp image kernels were good/fair (1.9-2.4), while smooth kernel provided only acceptable/poor image quality (3.9-4.4). Coronal oblique images were rated superior to assess in-stent lumen rather than axial. Using medium and sharp kernels, the visible stent lumen was significantly greater than using smooth kernel (P<0.001). thirteen out of fourteen patients (24/25 stents) were correctly classified as patent. In one patient, in-stent stenosis (> or =50%) was falsely diagnosed using CT angiography (CTA) with smooth kernel and was, therefore, rated as false positive. Coronal oblique views, as well as medium and sharp kernels, have shown the best results regarding image quality to assess stent patency in the lower limb. Therefore, MDCT could be a valuable non-invasive modality for stent imaging in the peripheral vasculature.

Sonographic Follow‐up After Visceral Artery Stenting

Abstract: Sonography is a useful tool in the follow-up of patients after visceral artery stenting. Despite the fact that none of the renal artery stents were visualized directly, the flow parameters could be evaluated, and the pathologic changes were found.
