Axial CT of a stable patient with a fracture of the right pubic ramus (circled in A) presenting with a small focal region of contrast extravasation (circled in B). Proximal angiograms, from the right external iliac artery (C) and from right internal iliac artery (D), showing no signs of contrast extravasation in correspondence of the site of the findings on CT. The selective catheterizations of the suspected injured arteries based on CT findings, for the digital studies, i.e., of the right external obturator artery [non-subtracted (E) and subtracted (F) angiograms] and of the right internal obturator artery [non-subtracted (G) and subtracted (H) angiograms], showing no signs of bleeding. According to the proposed algorithm, the angiographic study was considered completed and the empiric embolization was not performed
