Evaluation of potential renal donors and renal allograft recipients: digital video subtraction angiography.

Digital video subtraction angiography is a safe, easily performed, outpatient procedure that was applied to evaluating the arterial anatomy of 11 potential renal donors and 22 examinations of 19 renal allograft recipients. Digital intravenous angiography depicted the number and position of renal arteries preoperatively in renal donors and excluded renal arterial or parenchymal disease. It accurately defined transplant arterial stenoses and demonstrated the status of the intrarenal circulation. No morbidity nor decreased renal function resulted. Digital video subtraction angiography has become the procedure of choice for these referrals at this institution.
