OBJECTIVES: Renal arteriovenous (AV) @entity292 is uncommon, but sometimes causes severe @entity811 . To assess the value of color Doppler ultrasound (CD-US) for the detection of @entity8 , we retrospectively reviewed our experience with this disease. MATERIALS AND METHODS: Between 1994 and 2001, five @entity1 with @entity8 were diagnosed in our institution. Post-biopsy @entity2548 of the transplanted kidney was found in 1 @entity1 . @entity8 was detected in 2 @entity1 who presented with gross @entity811 . In the remaining 2 @entity1 , @entity8 was discovered incidentally during abdominal ultrasonography. We evaluated gray-scale and CD-US imaging in those five @entity1 . RESULTS: In all 5 @entity1 , CD-US showed a whirling flow pattern within an echo-free structure suggesting @entity2548 . However, it was difficult to distinguish @entity2548 from @entity439 using only CD-US. While pulsed spectral Doppler evaluation of the lesion might be helpful, prompt venous filling on dynamic CT scan and/or renal arteriography was the most definitive sign for diagnosing the @entity8 . CONCLUSIONS: CD-US is excellent for demonstrating turbulent blood flow signals within the kidney. However, another radiographic study is required to give a definite diagnosis of @entity8 . Due to its low cost, low risk and wide availability, we recommend that CD-US be the first-line imaging procedure for the evaluation of @entity811 and @entity8 as well as for followup for @entity8 .
