Is it necessary to study accessory arteries when screening the renal arteries for XXXX ?

PURPOSE: To determine the prevalence of isolated hemodynamically significant stenoses of accessory renal arteries when the main renal arteries are patent. MATERIALS AND METHODS: In 68 adults (24 @entity1 , mean age, 67 years +/- 10; 44 @entity1 , mean age, 67 years +/- 12), angiograms that fulfilled the following criteria were studied: (a) technically adequate renal angiograms obtained to evaluate suspected @entity2792 and (b) angiographically documented hemodynamically significant @entity850 of any renal artery. The percentage of kidneys and the percentage of @entity1 with hemodynamically significant isolated stenoses of accessory renal arteries were calculated. RESULTS: Eighty-seven kidneys in 68 @entity1 had hemodynamically significant @entity2791 . Fifteen kidneys had 16 accessory renal arteries. Four accessory arteries in three @entity1 had hemodynamically significant stenoses. Only one of 68 @entity1 (1.5%) had an accessory artery @entity850 unaccompanied by a main @entity2791 in either kidney; this @entity1 had bilateral hemodynamically significant accessory artery stenoses. Two @entity1 had coexistent hemodynamically significant stenoses of accessory and main renal arteries. CONCLUSION: The prevalence of a hemodynamically significant @entity850 isolated to an @entity8 was 1.5% in our study. Thus, failure to detect accessory renal arteries should not unduly affect the utility of a noninvasive test for detecting @entity2792 .
