“…Follow up of endovascularly treated mesenteric vessels is said to be important because of the high incidence of restenosis or occlusion in the stented vessels, but there is no evidence that intervention on the basis of duplex‐defined restenosis improves long‐term patency or prevents recurrence of symptoms 9 …”
Although ultrasound is a convenient, non-invasive tool for follow up of endovascular treatment of mesenteric stenosis, its use is unclear as in our study restenosis did not correlate with recrudescence of symptoms.

“…Using native vessel criteria for reintervention in in-stent restenosis, Morvay et al found that intervention based on ultrasound findings did not improve patency outcomes or prevent recurrence of symptoms. 27 Recently, in a hypothesis-seeking study, Mitchell et al concluded that DUS criteria for native SMA stenosis cannot be applied to stented SMA stenosis. 28 Early in our experience, angiograms would be performed based on the lower nonvalidated velocity criteria to confirm the diagnosis of in-stent restenosis.…”
Visceral stenting has an exceptionally high technical success rate with low procedural morbidity and mortality. Clinical primary patency and primary patency were significantly higher for the SMA group than for the CA group. Our data suggest that CA atherosclerotic lesions do not respond well to endovascular stenting, bringing into question its clinical utility.
“…Όταν συνδυάζονται τα μορφολογικά και τα ποσοτικά κριτήρια, η ευαισθησία της μεθόδου για την ανίχνευση στένωσης της νεφρικής αρτηρίας (της τάξεως του 70% ή μεγαλύτερης) ανέρχεται στο 72%-92%. Επίσης, η doppler υπερηχοτομογραφία μπορεί να χρησιμοποιηθεί με μεγάλη ακρίβεια για τον έλεγχο της βατότητας του αγγείου μετά την τοποθέτηση stent 7 παρόλο που δεν είναι δυνατή η απευθείας απεικόνισή του 30 .…”
