Fig. 2

Topography of the intra-pelvic arterial lesions found in the study. All the lesions are arbitrarily reported on the right side of the pelvis for clarity purposes. Each circle corresponds to an arterial lesion location; the size of each circle is proportional to the number of arterial lesions found at the particular location, and the number within each circle refers to the number of cases found at the particular location. Artery names are reported on the left side of the pelvis. This figure is authors’ own work
