Intraoperative duplex sonography during renal artery reconstruction

Accuracy of duplex sonography scans after renal artery stenting

“…22,23 Moreover, despite the compliance changes associated with RA bypass and endarterectomy, we have observed a high correlation between native RDS criteria for intraoperative assessment and postoperative surveillance compared with cut-film angiography. 2 A potential limitation of this and many other studies is the accuracy of the most common reference standard-DSA. Angiography provides a two-dimensional image of a three-dimensional structure.…”

“…1 RDS has also proven utility as an intraoperative completion study after open operative repair. 2 Moreover, RDS accurately defines patency, restenosis, and occlusion in followup after operative repair of RVD. 3 In addition to evaluation for clinical disease, RDS has defined the prevalence of RVD in a large, free-living group of elderly participants and defined the rate of anatomic progression in this group on follow-up.…”

Renovascular disease in children and adolescents

“…In the last half, intraoperative RDS scanning was used to assess the adequacy of repair. 29 In this instance, major defects were revised at the first procedure. Overall, three major defects were identified by completion RDS scans and each was repaired.…”

Surgical Revascularization of Atherosclerotic Renovascular Disease: State of the Art

“…15 They have also proved valid in a retrospective study when preoperative radiographic studies were compared with intraoperative duplex prior to surgical repair. 16 We have examined the results of intraoperative duplex in an additional 249 renal artery repairs with anatomic follow-up evaluation.…”

“…15 Freedom from static projections, the absence of potentially nephrotoxic contrast material, and the hemodynamic data provided by Doppler spectral analysis makes duplex sonography a very useful intraoperative method to assess renovascular repairs.…”
