INTRAOPERATIVE COLOR DOPPLER SONOGRAPHY DURING RENAL-ARTERY REVASCULARIZATION

Intraoperative color Doppler sonography is emerging as a useful proced ure for evaluating renal arteries during transaortic renal endarterect omy or bypass grafting [1-3]. Technical difficulties encountered durin g surgical renal revascularization, such as intimal defects or flaps, partial or complete thrombosis, and anastomotic stenosis of the renal artery, can be difficult to detect and evaluate. Intraoperative color Doppler sonography allows evaluation at a time when the problem is oft en correctable. We have been performing intraoperative sonographic stu dies of the renal artery for several years and have studied 151 vessel s. In this pictorial essay, we present some of our observations on the se cases.
