Intraoperative color Doppler sonography is emerging as a useful procedure
for evaluating renal arteries during transaortic renal endarterectomy or
bypass grafting. Technical difficulties encountered during surgical renal
revascularization, such as intimal defects or flaps, partial or complete
thrombosis, and anastomotic stenosis of the renal artery, can be difficult
to defect and evaluate. Intraoperative color Doppler sonography allows
evaluation at a time when the problem is often correctable. We have been
performing intraoperative sonographic studies of the renal artery for
several years and have studied 151 vessels. In this pictorial essay, we
present some of our observations on these cases.
