Abstract
Introduction and iliac arteries, but did suggest an AVF at the left renal pedicle. T1-weighted CE-MRA during injection Arteriovenous fistula (AVF) of the renal pedicle is a of 35 ml of gadolinium-DTPA confirmed this finding (Fig. 1). Cardiological investigation revealed a dirare complication of nephrectomy. Just 68 cases have been described since the first report in 1934. As latation of the left ventricle with a cardiac output of 8.1 l/min. cardiac failure is a frequent and serious sequela, closure of the fistula is indicated in all cases. Conventional As the haemodynamic alterations did not pose a serious hazard for operation, pre-operative endoangiography has been considered the best technique to identify the anatomical orientation of the fistula. luminal closure of the AVF was not performed. By a transperitoneal approach the remnant of the left renal We used Contrast-Enhanced Magnetic Resonance Angiography (CE-MRA) in the diagnostic work-up of artery was occluded with metal clips. Postoperatively no complications were noted. His lumbar and abthis case with superior results. dominal pain disappeared completely and the cardiac output decreased to 5.2 l/min. CE-MRA was repeated and showed complete disappearance of the fistula (Fig. Report 2).
