Rg. Mcwilliams et al., THE DEMONSTRATION OF AORTOCAVAL FISTULAS BY HELICAL COMPUTED-TOMOGRAPHY, British journal of radiology, 68(810), 1995, pp. 653-656
We report the helical computed tomography findings in two patients wit
h spontaneous aortocaval fistula (ACF) complicating abdominal aortic a
neurysm. The use of overlapping slices produced high quality multiplan
ar reformats which provided anatomical information about the likely si
te of the ACF and also the relationship of the renal arteries to the n
eck of the aneurysm.
